    <title language="eng">Biocompatible Macroion/Growth Factor Assemblies for Medical Applications</title>
    <abstract language="eng">Growth factors are a class of proteins that play a role in the proliferation (the increase in the number of cells resulting from cell division) and differentiation (when a cell undergoes changes in gene expression becoming a more specific type of cell) of cells. They can have both positive (accelerating the normal healing process) and negative effects (causing cancer) on disease progression and have potential applications in gene therapy and wound healing. However, their short half-life, low stability, and susceptibility to degradation by enzymes at body temperature make them easily degradable in vivo. To improve their effectiveness and stability, growth factors require carriers for delivery that protect them from heat, pH changes, and proteolysis. These carriers should also be able to deliver the growth factors to their intended destination. This review focuses on the current scientific literature concerning the physicochemical properties (such as biocompatibility, high affinity for binding growth factors, improved bioactivity and stability of the growth factors, protection from heat, pH changes or appropriate electric charge for growth factor attachment via electrostatic interactions) of macroions, growth factors, and macroion-growth factor assemblies, as well as their potential uses in medicine (e.g., diabetic wound healing, tissue regeneration, and cancer therapy).&#13;
Specific attention is given to three types of growth factors: vascular endothelial growth factors, human fibroblast growth factors, and neurotrophins, as well as selected biocompatible synthetic macroions (obtained through standard polymerization techniques) and polysaccharides (natural macroions composed of repeating monomeric units of monosaccharides). Understanding the mechanisms by which growth factors bind to potential carriers could lead to more effective delivery methods for these proteins, which are of significant interest in the diagnosis and treatment of neurodegenerative and civilization diseases, as well as in the healing of chronic wounds.</abstract>

    <title language="eng">Long-term corrosion studies of CrCoNi and CrMnFeCoNi in sulfuric acid</title>
    <abstract language="eng">This study investigates the long-term corrosion behavior of CrCoNi and CrMnFeCoNi MPEAs over 28 d in 1 M H2SO4. Corrosion progression and passive film evolution were analyzed using open circuit potential measurements, electrochemical impedance spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy. Unlike short-term polarization tests, where CrCoNi exhibited intergranular corrosion, long-term immersion resulted in a stable, Cr-rich passive oxide layer. In contrast, CrMnFeCoNi formed a porous mixed oxide layer, increasing its susceptibility to degradation and revealing a distinct corrosion mechanism. X-ray photoelectron spectroscopy tracking at weekly intervals showed that prolonged immersion led to the transformation of sulfide/sulfite species into a sulfate-containing surface film. This effect was only detectable in long-term corrosion studies. These findings provide new insights into the time-dependent degradation mechanisms of MPEAs and demonstrate that corrosion mechanisms differ significantly from short-term polarization tests. This highlights the need for long-term studies to properly assess material stability in practical applications.</abstract>

    <title language="eng">Deposition and Characterization of Cu-Enhanced High-Entropy Alloy Coatings via DC Magnetron Sputtering</title>
    <abstract language="eng">Protection against microbiologically influenced corrosion (MIC) is critical for materials used in aquatic environments, as MIC accelerates material degradation and leads to faster structural failure. Copper (Cu) has the potential to substantially improve the MIC resistance in alloys. In this study, high-entropy alloy (HEA) coatings containing Cu were deposited using DC (Direct Current) magnetron sputtering to enhance the corrosion resistance and mechanical properties of various substrates. Two CuCrFeMnNi HEA compositions in the form of bulk alloys and PVD (Physical Vapor Deposition) coatings, with 5% and 10% Cu, were analyzed for their microstructural, mechanical, and anticorrosive characteristics. Deposition parameters were varied to select the optimal values. Microstructural evaluations using SEM-EDS (scanning electron microscopy and energy dispersive X-ray spectroscopy), XRD (X-ray diffraction), and AFM (atomic force microscopy) revealed uniform, dense coatings with good adhesion composed of dendritic and interdendritic BCC (body-centered cubic) and FCC (face centered cubic) structures, respectively. Microhardness tests indicated improved mechanical properties for the samples coated with developed HEAs. The coatings exhibited improved corrosion resistance in NaCl solution, the 10% Cu composition displaying the highest polarization resistance and lowest corrosion rate. These findings suggest that Cu-containing HEA coatings are promising candidates for applications requiring enhanced corrosion protection.</abstract>

In this study, high-entropy alloy (HEA) coatings containing Cu were deposited using DC (Direct Current) magnetron sputtering to enhance the corrosion resistance and mechanical properties of various substrates. Two CuCrFeMnNi HEA compositions in the form of bulk alloys and PVD (Physical Vapor Deposition) coatings, with 5% and 10% Cu, were analyzed for their microstructural, mechanical, and anticorrosive characteristics. Deposition parameters were varied to select the optimal values. Microstructural evaluations using SEM-EDS (scanning electron microscopy and energy dispersive X-ray spectroscopy), XRD (X-ray diffraction), and AFM (atomic force microscopy) revealed uniform, dense coatings with good adhesion composed of dendritic and interdendritic BCC (body-centered cubic) and FCC (face centered cubic) structures, respectively. Microhardness tests indicated improved mechanical properties for the samples coated with developed HEAs. The coatings exhibited improved corrosion resistance in NaCl solution, the 10% Cu composition displaying the highest polarization resistance and lowest corrosion rate. These findings suggest that Cu-containing HEA coatings are promising candidates for applications requiring enhanced corrosion protection.&lt;\/jats:p&gt;","DOI":"10.3390\/app15041917","type":"journal-article","created":{"date-parts":[[2025,2,12]],"date-time":"2025-02-12T15:25:57Z","timestamp":1739373957000},"page":"1917","source":"Crossref","is-referenced-by-count":0,"title":["Deposition and Characterization of Cu-Enhanced High-Entropy Alloy Coatings via DC Magnetron Sputtering"],"prefix":"10.3390","volume":"15","author":[{"given":"Arcadii","family":"Sobetkii","sequence":"first","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8105-6609","authenticated-orcid":false,"given":"Laurentiu-Florin","family":"Mosinoiu","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7898-8774","authenticated-orcid":false,"given":"Stefania","family":"Caramarin","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8306-9246","authenticated-orcid":false,"given":"Dumitru","family":"Mitrica","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3902-5876","authenticated-orcid":false,"given":"Laura-Madalina","family":"Cursaru","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"given":"Alexandru-Cristian","family":"Matei","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2964-6764","authenticated-orcid":false,"given":"Ioan-Albert","family":"Tudor","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"given":"Beatrice-Adriana","family":"Serban","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"given":"Mihai","family":"Ghita","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"given":"Nicoleta","family":"Vitan","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"}]},{"given":"Julia","family":"Witt","sequence":"additional","affiliation":[{"name":"Federal Institute of Materials Research and Testing (BAM), 12205 Berlin, Germany"}]},{"given":"Ozlem","family":"Ozcan","sequence":"additional","affiliation":[{"name":"Federal Institute of Materials Research and Testing (BAM), 12205 Berlin, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3426-5085","authenticated-orcid":false,"given":"Bogdan","family":"Postolnyi","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"},{"name":"Institute of Physics for Advanced Materials, Nanotechnology and Photonics, Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"},{"name":"Faculty of Electronics and Information Technologies, Sumy State University, 116 Kharkivska St., 40007 Sumy, Ukraine"}]},{"given":"Alexander","family":"Pogrebnjak","sequence":"additional","affiliation":[{"name":"National R&amp;D Institute for Non-Ferrous and Rare Metals\u2014IMNR, 102 Biruintei Blvd, 077145 Pantelimon, Romania"},{"name":"Faculty of Electronics and Information Technologies, Sumy State University, 116 Kharkivska St., 40007 Sumy, Ukraine"},{"name":"Faculty of Material Science and Technology in Trnava, Institute Materials, Slovak University of Technology in Bratislava, 91724 Trnava, Slovakia"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Knisz, J., Eckert, R., Gieg, L.M., Koerdt, A., Lee, J.S., Silva, E.R., Skovhus, T.L., An Stepec, B.A., and Wade, S.A.

    <title language="eng">Mussel-Inspired Multivalent Linear Polyglycerol Coatings Outperform Monovalent Polyethylene Glycol Coatings in Antifouling Surface Properties</title>
    <abstract language="eng">Biofouling constitutes a major challenge in the application of biosensors and biomedical implants, as well as for (food) packaging and marine equipment. In this work, an antifouling surface coating based on the combination of mussel-inspired dendritic polyglycerol (MI-dPG) and an amine-functionalized block copolymer of linear polyglycerol (lPG−b−OA11, OA = oligo-amine) was developed. The coating was compared to a MI-dPG surface which was postfunctionalized with commercially available amine-terminated Polyethylene glycol (HO−PEG−NH2) of similar molecular weight. In the current work, These coatings were compared in their chemical stability, protein fouling characteristics, and cell fouling characteristics. The lPG−b−OA11-functionalized coating showed high chemical stability in both phosphate buffered saline (PBS) and sodium dodecyl sulfate (SDS) solutions and reduced the adhesion of fibrinogen from human plasma with 99% and the adhesion of human serum albumin with 96%, in comparison to the bare titanium dioxide substrate. Furthermore, the Proliferation of human umbilical vein endothelial cells (HUVECs) was reduced with 85% when the lPG−b−OA11 system was compared to bare titanium dioxide. Additionally, a reduction of 94% was observed when the lPG−b−OA11 system was compared to tissue culture polystyrene.</abstract>

    <title language="eng">Efficient detection of localized corrosion processes on stainless steel by means of scanning electrochemical microscopy (SECM) using a multi-electrode approach</title>
    <abstract language="eng">High resolution analysis of corrosion processes on stainless steels is a challenging task. The application of local electrochemical techniques such as scanning electrochemical microscopy (SECM) has opened new possibilities for the detection of corrosion products and activity on metallic surfaces. However, due to its stochastic nature, the analysis of pitting corrosion requires being at the right place at the right time. Scanning over large areas at a high resolution not only leads to long scan durations but also leaves many short-lived processes undetected. In this paper we present the combined automated operation of SECM and wire multi-electrodes connected to a multi-electrode analyzer (MMA). The inter-electrode currents between 25 wire electrodes connected via zero resistance ammeters (ZRA) are measured by the MMA at open circuit potential (OCP) and the electrodes reporting anodic currents are detected automatically to be analyzed by means of SECM. The results demonstrate the successful application of this methodology for the detection of unstable and stable pitting processes on 304 stainless steel in a corrosive aqueous environment.</abstract>

    <title language="eng">Iron to Gas: Versatile Multiport Flow-Column Revealed Extremely High Corrosion Potential by Methanogen-Induced Microbiologically Influenced Corrosion (Mi-MIC)</title>
    <abstract language="eng">Currently, sulfate-reducing bacteria (SRB) is regarded as the main culprit of microbiologically influenced corrosion (MIC), mainly due to the low reported corrosion rates of other microorganisms. For example, the highest reported corrosion rate for methanogens is 0.065 mm/yr. However, by investigating methanogen-induced microbiologically influenced corrosion (Mi-MIC) using an in-house developed versatile multiport flow test column, extremely high corrosion rates were observed. We analyzed a large set of carbon steel beads, which were sectionally embedded into the test columns as substrates for iron-utilizing methanogen Methanobacterium IM1. After 14 days of operation using glass beads as fillers for section separation, the highest average corrosion rate of Methanobacterium IM1 was 0.2 mm/yr, which doubled that of Desulfovibrio ferrophilus IS5 and Desulfovibrio alaskensis 16109 investigated at the same conditions. At the most corroded region, nearly 80% of the beads lost 1% of their initial weight (fast-corrosion), resulting in an average corrosion rate of 0.2 mm/yr for Methanobacterium IM1-treated columns. When sand was used as filler material to mimic sediment conditions, average corrosion rates for Methanobacterium IM1 increased to 0.3 mm/yr (maximum 0.52 mm/yr) with over 83% of the beads having corrosion rates above 0.3 mm/yr. Scanning electron images of metal coupons extracted from the column showed methanogenic cells were clustered close to the metal surface. Methanobacterium IM1 is a hydrogenotrophic methanogen with higher affinity to metal than H2. Unlike SRB, Methanobacterium IM1 is not restricted to the availability of sulfate concentration in the environment. Thus, the use of the multiport flow column provided a new insight on the corrosion potential of methanogens, particularly in dynamic conditions, that offers new opportunities for monitoring and development of mitigation strategies. Overall, this study shows under certain conditions methanogenic archaea can cause higher corrosion than SRB, specific quantifications, i.e., maximum, average, and minimum corrosion rates can be determined, and that spatial statistical evaluations of MIC can be carried out.</abstract>

    <title language="eng">Trained to corrode: Cultivation in the presence of Fe(III) increases the electrochemical activity of iron reducing bacteria – An in situ electrochemical XANES study</title>
    <abstract language="eng">This paper reports results from in situ electrochemical X-ray absorption near-edge spectroscopy (XANES) studies of the corrosion processes on model thin iron films in the presence of iron reducing bacteria Shewanella putrefaciens. Here we investigate the electrochemical activity of two cultures grown in the presence and absence of Fe(III) citrate in the culture medium. The XANES spectra and the OCP data of the Fe sample incubated with the culture grown in absence of Fe(III) did not show any significant changes during twenty hours of monitoring. In the case of the culture grown in Fe(III) containing medium, an accelerated dissolution of the iron film was observed together with the formation of a mixed Fe(II)-Fe(III) hydroxide surface layer. The open circuit potential (OCP) steadily approached the free corrosion potential of iron in neutral chloride containing electrolytes, indicating a continuous dissolution process without passivation.</abstract>

    <title language="eng">Corrosion and passivation of AlCrFe2Ni2Mox high-entropy alloys in sulphuric acid</title>
    <abstract language="eng">Corrosion behaviour of AlCrFe2Ni2Mox (x = 0.0, 0.1, 0.15, 0.3 and 0.6) high-entropy alloys was investigated in a 0.1 M H2SO4 solution. Passive films formed upon anodic polarisation, built of Al-based inner layer and (Cr, Fe, Mo)-based outer layer, had good protective properties. In particular, they prevented corrosion of the (Al, Ni)-rich BCC-B2 phase, which was observed under open-circuit conditions. Moderate amounts of Mo, up to x = 0.3, positively affected the passivation ability of AlCrFe2Ni2. Significant changes in microstructure and phase composition of the alloy at higher Mo concentrations (x = 0.6) resulted in deterioration of its corrosion resistance.</abstract>

    <title language="eng">Designing durable, sustainable, high-performance materials for clean energy infrastructure</title>
    <abstract language="eng">Civilization and modern societies would not be possible without manmade materials. Considering their production volumes, their supporting role in nearly all industrial processes, and the impact of their sourcing and production on the environment, metals and alloys are and will be of prominent importance for the clean energy transition. The focus of materials discovery must move to more specialized, application-tailored green alloys that outperform the legacy materials not only in performance but also in sustainability and resource efficiency. This white paper summarizes a joint Canadian-German initiative aimed at developing a materials acceleration platform (MAP) focusing on the discovery of new alloy families that will address this challenge. We call our initiative the “Build to Last Materials Acceleration Platform” (B2L-MAP) and present in this perspective our concept of a three-tiered self-driving laboratory that is composed of a simulation-aided pre-selection module (B2L-select), an artificial intelligence (AI)-driven experimental lead generator (B2L-explore), and an upscaling module for durability assessment (B2L-assess). The resulting tool will be used to identify and subsequently demonstrate novel corrosion-resistant alloys at scale for three key applications of critical importance to an offshore, wind-driven hydrogen plant (reusable electrical contacts, offshore infrastructure, and oxygen evolution reaction catalysts).</abstract>

    <title language="eng">Multiscale insights into fibroblast growth factor 23 adsorption on polyelectrolyte layers: From molecular properties to biointerfaces</title>
    <abstract language="eng">Fibroblast growth factor 23 (FGF23) is a clinically significant protein hormone regulating phosphate and vitamin D metabolism, with elevated levels linked to chronic kidney disease, cardiovascular disorders, and impaired bone homeostasis. Despite its relevance as both a biomarker and a therapeutic target, its interactions with functional biomaterials remain poorly understood. In this work, we investigate the FGF23 adsorption on polyelectrolyte layers using a combination of theoretical modeling and experimental methods. Theoretical calculations provided insights into the protein's charge distribution and diffusion properties, while experimental measurements quantified its hydrodynamic diameter, electrophoretic mobility, and electrokinetic charge over a broad range of pH values. Microscale thermophoresis revealed quantitative binding affinities of FGF23 to hyaluronic acid, chitosan, and poly(diallyldimethylammonium chloride). Adsorption studies on mica, silica, and polyelectrolyte mono- and bilayers showed that FGF23 binds to both negatively and positively charged substrates, with binding affinities following: hyaluronic acid &lt; poly(diallyldimethylammonium chloride) &lt; chitosan. Desorption occurred more readily from negatively charged surfaces (mica, silica and hyaluronic acid), indicating weaker interactions compared to positively charged layers. These results reveal fundamental aspects of protein –polyelectrolyte interactions and highlight the reversible binding capacity of FGF23 to negatively charged surfaces. Such adsorption behavior provides a physicochemical framework for considering FGF23-polyelectrolyte systems in the design of therapeutic carriers and bioactive materials. However, any direct relevance to wound healing, chronic kidney disease, or cardiovascular disorders remains prospective and requires dedicated biological validation.</abstract>

    <title language="eng">Effect of the Anchoring Layer and Transport Type on the Adsorption Kinetics of Lambda Carrageenan</title>
    <abstract language="eng">The kinetics of lambda carrageenan (λ-car) adsorption/desorption on/from anchoring layers under diffusion- and convection-controlled transport conditions were investigated. The eighth generation of poly(amidoamine) dendrimers and branched polyethyleneimine possessing different shapes and polydispersity indexes were used for anchoring layer formation. Dynamic light scattering, electrophoresis, streaming potential measurements, optical waveguide lightmode spectroscopy, and quartz crystal microbalance were applied to characterize the formation of mono- and bilayers. The unique combination of the employed techniques enabled detailed insights into the mechanism of the λ-car adsorption mainly controlled by electrostatic interactions. The results show that the macroion adsorption efficiency is strictly correlated with the value of the final zeta potentials of the anchoring layers, the transport type, and the initial bulk concentration of the macroions. The type of the macroion forming the anchoring layer had a minor impact on the kinetics of λ-car adsorption. Besides significance to basic science, the results presented in this paper can be used for the development of biocompatible and stable macroion multilayers of well-defined electrokinetic properties and structure.</abstract>

    <title language="eng">Synthesis and characterization of lipopolysaccharide (LPS) anchored polystyrene microparticles as a synthetic model system for attachment studies</title>
    <abstract language="eng">Outer membrane lipopolysaccharides (LPS) play a crucial role in determining attachment behavior and pathogenicity of bacteria. The aim of this study was to develop a simple procedure for anchoring bacterial lipopolysaccharides to polystyrene (PS) microparticles as a model system for in situ attachment studies. By using a swellcapture methodology, commercially available LPS of Pseudomonas aeruginosa (strain ATCC 27316 serotype 10.22) was anchored onto PS microparticles in a proof-of-concept study. A detailed chemical and morphological characterization has proven the success of LPS incorporation. It was shown that the coverage and structure of the LPS film was concentration dependent. The procedure can easily be adapted to LPS of other bacterial strains to generate a synthetic model toolkit for attachment studies.</abstract>

    <title language="eng">Corrosion protection properties of poly(4-vinyl pyridine) containing multilayer polymeric coatings on magnesium alloy AZ31</title>
    <abstract language="eng">The aim of this study is to develop polymeric thin films for corrosion protection of magnesium alloy AZ31. As polymer matrix, poly(4-vinyl pyridine) (P4VP) is selected due to its semiconducting properties and protonic conductivity. Polyacrylic acid is tested as crosslinking layers to improve interfacial adhesion. The macroscopic corrosion properties of the multilayer coatings are investigated by means of electrochemical methods, such as linear sweep voltammetry and electrochemical impedance spectroscopy (EIS), in corrosive media simulating technical and biomedical applications. It is demonstrated that thin multilayer coatings can suppress the corrosion rates of magnesium alloys. To our best knowledge, this is the first demonstration of the use of P4VP as a conducting polymer film with protonic conductivity for corrosion protection of magnesium alloys.</abstract>

    <title language="eng">Effect of organic conditioning layers adsorbed on stainless steel AISI 304 on the attachment and biofilm formation of electroactive bacteria Shewanella putrefaciens CN32</title>
    <abstract language="eng">The initial attachment and subsequent biofilm formation of electroactive bac-teriaShewanella putrefaciensCN32 was investigated to clarify the influence oforganic conditioning layers. A selection of macromolecules and self-assembledmonolayers (SAMs) of different chain lengths and functional groups were pre-pared and characterized by means of infrared spectroscopy in terms of theirchemistry. Surface energy and Zeta (ζ-) potential of the conditioning layers wasdetermined with contact angle and streaming current measurements. Amongthe studied surface parameters, a high polar component and a high ratio ofpolar-to-disperse components of the surface energy has emerged as a successfulindicator for the inhibition of the initial settlement ofS. putrefacienson stainlesssteel AISI 304 surfaces. Considering the negative surface charge of planktonicS. putrefacienscells, and the strong inhibition of cell attachment by positivelycharged polyethylenimine (PEI) conditioning layers, our results indicate thatelectrostatic interactions do play a subordinate role in controlling the attach-ment of this microorganism on stainless steel AISI 304 surfaces. For the biofilmformation, the organization of the SAMs affected the local distribution of thebiofilms. The formation of three-dimensional and patchy biofilm networks waspromoted with increasing disorder of the SAMs.</abstract>

    <title language="eng">DELTA - Investigation of corrosion and microbially influenced corrosion processes by means of X-Ray absorption spectroscopy</title>
    <abstract language="eng">Alloys relevant for corrosion research are inherently complex in chemical composition and microstructure. Their local surface chemistry differs significantly from the bulk composition and their surfaces are subjected to ever changing environmental conditions. Thus, a thorough understanding of the mechanisms leading to material degradation and failure requires a detailed characterisation of the initial and final states as well as an adequate monitoring of the relevant properties as a function of time. Moreover, corrosion products tend to oxidize in contact with the atmosphere. Microbially influenced corrosion (MIC) poses a particular challenge regarding the experimental methods that can be used for the investigations. The use of highly sensitive methods of ultra-high vacuum surface analysis requires the removal of the biofilm, which leads to significant changes in the interfacial chemistry. &#13;
&#13;
In recent projects we applied X-ray absorption near edge spectroscopy (XANES) to investigate mechanisms of aqueous corrosion, high temperature corrosion and MIC processes of stainless steel and multi-principal element alloys (MPEAs). By combining in situ XANES studies on model thin films with ex situ XANES analysis of technical samples we aimed to obtain a holistic understanding of degradation processes. &#13;
&#13;
In this presentation we will summarize our results on the application of XANES to corrosion and MIC research with two case studies. In the first case study, in situ and ex situ XANES were used for the investigation of aqueous and high-temperature corrosion processes of alloys from FeNiCr-Mn MPEA family to clarify the role of Mn in determining the corrosion resistance and passive film formation. Our results indicate that Mn plays a major role in suppressing Fe oxidation. In the second example we have shown by means of in situ and ex situ XANES analysis that cultivation of metal reducing bacteria (MRB) in abundance of Fe(III) ions leads to a significant increase in electrochemical activity and thus, to an accelerated corrosion of the metallic substrate. This implies that bacterial colonies released from active corrosion sites might show a preconditioning effect and pose a higher corrosion risk.</abstract>

    <title language="eng">In Situ Atomic Force Microscopy Analysis of the Corrosion Processes at the Buried Interface of an Epoxy-like Model Organic Film and AA2024-T3 Aluminum Alloy</title>
    <abstract language="eng">The application of characterization methods with high spatial resolution to the analysis of buried coating/metal interfaces requires the design and use of model systems. Herein, an epoxy-like thin film is used as a model coating resembling the epoxy-based coatings and adhesives widely used in technical applications. Spin coating is used for the deposition of a 30 nm-thin bilayer (BL) composed of poly-(ethylenimine) (PEI) and poly[(o-cresyl glycidyl ether)-co-formaldehyde] (CNER). Fourier-transform infrared spectroscopy (FTIR) results confirm that the exposure of coated AA2024-T3 (AA) samples to the corrosive electrolyte solution does not cause the degradation of the polymer layer. In situ atomic force microscopy (AFM) studies are performed to monitor local corrosion processes at the buried interface of the epoxy-like film and the AA2024-T3 aluminum alloy surface in an aqueous electrolyte solution. Hydrogen evolution due to the reduction of water as the cathodic corrosion reaction leads to local blister formation. Based on the results of the complementary energy-dispersive X-ray spectroscopy (EDX) analysis performed at the same region of interest, most of the hydrogen evolved originates at the vicinity of Mg-containing intermetallic particles.</abstract>

    <title language="eng">The comparison of the corrosion behavior of the CrCoNi medium entropy alloy and CrMnFeCoNi high entropy alloy</title>
    <abstract language="eng">This work presents the determination of the corrosion characteristics of CrCoNi (medium entropy alloy) and CrMnFeCoNi (high entropy alloy) in 0.1 M NaCl and 0.1 M H2SO4. The morphology and chemical composition of the oxide layers formed on CrCoNi and CrMnFeCoNi were comparatively analyzed by scanning Kelvin probe microscopy (SKPFM) and scanning electron microscopy (SEM) and supported with chemical analysis by means of inductively coupled plasma mass spectrometry (ICP-MS) and X-Ray photoelectron spectroscopy (XPS). The analysis of the 3p core level peaks showed that the oxide layer (native and after anodic passivation) on CrCoNi consisted mainly of Cr oxides, while the oxide layer on CrMnFeCoNi was primarily composed of a mixture of Cr and Fe oxides. In addition, XPS was utilized to assess the oxide layer thicknesses. These results were compared to the thicknesses obtained by means of electrochemical impedance spectroscopy (EIS), with both approaches yielding values up to about 4 nm depending on the electrolyte and the alloy. Cyclic polarization measurements indicated superior corrosion resistance of CrCoNi in both aqueous environments compared to CrMnFeCoNi, as well as to AISI 304 stainless steel.</abstract>

    <title language="eng">Development of layer-by-layer assembled thin coatings on aluminium alloy AA2024-T3 for high resolution studies of local corrosion processes</title>
    <abstract language="eng">The aim of this study is to develop nanometer-thin epoxy-based films on aluminium alloy AA2024-T3 as a model coating system for high resolution corrosion studies. Spin coating was used for the layer-by-layer (LbL) deposition of poly-(ethylenimine) (PEI) and poly([o-cresyl glycidyl ether]-co-formaldehyde) (CNER) bilayers. The film chemistry and the cross-linking process were characterized by means of Fourier-transform infrared spectroscopy (FTIR).&#13;
Ellipsometric data confirmed the linear increase of film thickness. The potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) results indicate the improvement of the film barrier properties with increasing film thickness. Mapping of the topography and the volta potential was performed by means of scanning Kelvin probe force microscopy (SKPFM).&#13;
The results indicate the presence of a homogeneous film structure, while the intermetallic phases can still be identified below the coating. The SKPFM Analysis confirmed that the model films are suitable for investigation of corrosion processes at the coating/metal interface.</abstract>

Auswirkungen auf Legierungsstabilität und Elektrokatalyse</title>
    <abstract language="eng">Multi-principal element alloys (MPEAs) are gaining interest in corrosion and electrocatalysis research due to their electrochemical stability across a broad pH range and the design flexibility they offer. Using the equimolar CrCoNi alloy, we observe significant metal dissolution in a corrosive electrolyte (0.1 M NaCl, pH 2) concurrently with the oxygen evolution reaction (OER) in the transpassive region despite the absence of hysteresis in polarization curves or other obvious corrosion indicators. We present a characterization scheme to delineate the contribution of OER and alloy dissolution, using scanning electrochemical microscopy (SECM) for OER-onset detection, and quantitative chemical analysis with inductively coupled-mass spectrometry (ICP-MS) and ultraviolet visible light (UV-Vis) spectroscopy to elucidate metal dissolution processes. In-situ electrochemical atomic force microscopy (EC-AFM) revealed that the transpassive metal dissolution on CrCoNi is dominated by intergranular corrosion. These results have significant implications for the stability of MPEAs in corrosion systems, emphasizing the necessity of analytically determining metal ions released from MPEA electrodes into the electrolyte when evaluating Faradaic efficiencies of OER catalysts. The release of transition metal ions not only reduces the Faradaic efficiency of electrolyzers but may also cause poisoning and degradation of membranes in electrochemical reactors.</abstract>
    <abstract language="deu">Multi-Hauptelement-Legierungen (MPEAs) gewinnen in der Korrosions- und Elektrokatalyseforschung aufgrund ihrer elektrochemischen Stabilität über einen breiten pH-Bereich und der Vielfalt der möglichen chemischen Zusammensetzungen zunehmend an Interesse. In unseren Untersuchungen mit der äquimolaren CrCoNi-Legierung in einem sauren Elektrolyten (0.1 M NaCl, pH 2) beobachteten wir eine signifikante Metallauflösung, die mit der Sauerstoffentwicklungsreaktion (OER) im transpassiven Bereich einhergeht, obwohl in zyklischen Polarisationskurven keine Hysterese auftrat oder andere offensichtliche Korrosionsindikatoren vorlagen. In diesem Artikel wird ein Charakterisierungskonzept eingeführt, dass die Beiträge der OER und der Legierungsauflösung differenziert. Hierfür kommt die elektrochemische Rastermikroskopie (SECM) zum Nachweis des Beginns der OER und die quantitative chemische Analyse mit induktiv gekoppelter Massenspektrometrie (ICP-MS) und UV/Vis-Spektrometrie zur Aufklärung der Metallauflösungsprozesse zum Einsatz. Die elektrochemische In situ-Atomkraftmikroskopie (EC-AFM) zeigte, dass die intergranulare Korrosion der dominierende Mechanismus der transpassive Metallauflösung von CrCoNi ist. Diese Ergebnisse besitzen erhebliche Auswirkungen für die Beurteilung der Stabilität von MPEAs in Korrosionssystemen und der Stromausbeute von OER-Katalysatoren auf der Basis von MPEAs. Die Daten unterstreichen die Notwendigkeit der analytischen Bestimmung von Metallionen, die von MPEA-Elektroden freigesetzt werden. Die Freisetzung von Übergangsmetallionen verringert nicht nur die Stromausbeute von Elektrolyseuren, sondern kann zu einer Schädigung von Membranen in elektrochemischen Reaktoren führen.</abstract>

    <title language="eng">The interplay of anodic passivation and oxygen evolution on multi-principal element alloys (MPEAs)</title>
    <abstract language="eng">Multi-principal element alloys (MPEAs) are of great academic and industrial interest as emerging materials for engineering applications as well as potential electrode materials in energy conversion and storage. Several MPEAs have been studied for their general corrosion behavior, but studies on their dissolution in the high anodic “transpassive” potentials relevant for oxygen evolution reaction (OER) and local corrosion behavior remained scarce. &#13;
In this project we have investigated CrMnFeCoNi, FeCrNi and CrCoNi MPEAs in terms of their transpassive behavior in NaCl electrolytes and artificial seawater [1, 2]. We introduced a characterization procedure to distinguish the individual contributions of oxygen evolution reaction (OER) and alloy dissolution [2]. This scheme utilizes scanning electrochemical microscopy (SECM) for detecting the onset of OER and employs quantitative chemical analysis methods, namely inductively coupled mass spectrometry (ICP-MS) and ultraviolet-visible light (UV-Vis) spectroscopy, to elucidate the processes of metal dissolution. In-situ atomic force microscopy (AFM) and scanning Kelvin probe force microscopy (SKPFM) were used to analyze the corrosion morphology and surface potentials before, during, and after passivity breakdown.&#13;
Our results clearly demonstrate the superior corrosion behavior of CrCoNi and FeCrNi MPEA in comparison to the CrFeMnCoNi HEA, as well as AISI 304 stainless steel. We have observed that significant OER occurs in parallel with metal dissolution on the CrCoNi and FeCrNi MPEA surfaces during anodic polarization at potentials relevant to water electrolysis. Most importantly, our findings underscore the necessity of analyzing metal ions dissolved into the electrolyte to accurately assess the Faradaic efficiencies of non-noble metal OER electrocatalysts. The presentation will summarize our characterization procedure and give an overview on the key properties of the studied MPEAs. &#13;

    <title language="eng">Material Acceleration Platforms of BAM (MAPs@BAM)</title>
    <abstract language="eng">Material Acceleration Platforms (MAPs) represent a transformative approach to the development of resilient and sustainable technology value chains. These platforms can identify candidate chemistries and structures via simulations, and database searches and leverage machine learning-based rapid screening to accelerate the discovery and deployment of novel materials, thereby addressing critical challenges in modern technology sectors.&#13;
Incorporating high-fidelity advanced characterization in the early phases of material development is crucial for early de-risking. Advanced characterization techniques, such as X-ray diffraction, advanced electrochemical and spectroscopic techniques provide comprehensive insights into the structural, chemical, and physical properties of materials. Long-term testing further contributes to the de-risking process by evaluating the durability and stability of materials under various environmental and operational conditions.&#13;
This presentation will briefly summarize how we address these issues at MAPs@BAM and provide deep-dives on best practices. As the demand for advanced materials continues to grow, MAPs will play an increasingly vital role in driving technological advancements and addressing global challenges.</abstract>

    <title language="eng">The effect of flavins on the corrosion properties of stainless steels during initial stages of microbiologically influenced corrosion</title>
    <abstract language="eng">Microbiologically influenced corrosion (MIC) on steel occurs where the presence and activity of microbes change the localized conditions on the surface of a metal substrate. For instance, metal reducing bacteria (MRB) are capable of utilizing metal compounds in the passive layer on stainless steel as electron acceptors during their metabolism. This weakening of the passive film not only leads to an acceleration of the general corrosion processes, but also increases the susceptibility of stainless steels to pitting corrosion. Even though the electron transfer mechanisms are not yet fully understood, recent research shows that the secretion of electron shuttles like flavins contribute significantly to the extracellular electron transfer (EET). Electron shuttle molecules like riboflavin (RB) or flavin mononucleotide (FMN) are secreted by MRB after the transition from planktonic to sessile mode and exist in the biofilm at low concentrations. Therefore, they are precise early phase indicators of bacterial settlement.&#13;
&#13;
This project aims at clarifying the electrochemical interaction mechanisms of MRB with stainless steel surfaces, with a special focus on the role of the extracellular redox molecules. The analysis of corrosion processes as a function of chloride and flavin concentration have been performed by means of electrochemical methods. Due to the differences in their chemical structure, FMN and RB have shown significant differences in terms of their adsorption behavior and the stability of the formed films, which directly influences the electron transfer processes. Therefore, Electrochemical Quartz Crystal Microbalance (eQCM) studies have been performed on sputtered FeCr electrodes to investigate the adsorption/desorption kinetics of flavins.&#13;
&#13;
The results of electrochemical studies are complemented by the analysis of the changes in the passive film chemistry and the chemical composition of the adsorbed films by means of Fourier Transform Infrared Reflection Absorption Spectroscopy (FT-IRRAS) and X-ray photoelectron spectroscopy (XPS). Changes in surface morphology have been investigated by means of Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM).The presentation will summarize our results on the degradation mechanisms of passive films on stainless steel surfaces in the presence of flavins and provide useful insights from a fundamental aspect for the understanding of the initial stages of microbiologically influenced corrosion.</abstract>

    <title language="eng">Chemical and electrochemical interaction mechanisms of metal-reducing bacteria with gold surfaces</title>
    <abstract language="eng">Bacterial biofilms are considered one of the salient contributing factors to the deterioration of metals and their alloys, occurring in virtually all environments and across various industrial systems. Considering the sheer magnitude of detrimental effects, it is of pertinent interest to elucidate the interaction mechanisms of sessile bacteria with metal and metal oxide surfaces to facilitate the development of efficient antifouling strategies. A common constituent of microbial communities within aquatic and sedimentary settings, the Shewanella genus consists of facultatively aerobic, Gram-negative bacterium which exhibit exceptional plasticity in respiratory capacities. During aerobic conditions, Shewanella utilizes oxygen as a terminal electron acceptor; conversely, under anaerobic conditions, it is able to undertake respiration by reducing alternative terminal electron acceptors such as oxidized metals via extracellular electron transfer mechanisms not yet thoroughly discerned.&#13;
The aim of this work is to explicate the mechanisms governing the initial bacterial adhesion and subsequent biofilm formation on metallic surfaces. To investigate this dynamic interplay, a combined approach has been followed which couples surface enhanced Raman spectroscopy (SERS) with electrochemical techniques using Shewanella sp. model biofilms. Gold nano-islands deposited on thin glass slides have been chosen as inert model substrates with good uniformity and high surface enhancement factor. Furthermore, the utilization of gold as substrate material not only allowed the differentiation of the sole effect of substrate polarization on bacterial attachment but also enabled a precise adjustment of the surface chemistry and surface energy by means of surface functionalization with organothiol self-assembled monolayers.&#13;
The results present the correlation of the primary settlement rate of bacteria on metallic substrates with the environmental parameters such as electrolyte composition and pH as well as surface-related properties like hydrophobicity/hydrophilicity and polarization. With the overall strategic goal of transferring this methodology to technical systems the results provide the fundamental basis for the bottom-up design of anti-fouling surfaces.</abstract>

    <title language="eng">Autonomous exploration of new alloy chemistries using a Material Acceleration Platform (MAP)</title>
    <abstract language="eng">The discovery and commercialization of new corrosion resistant alloys by conventional approaches and manual experimentation is a slow and expensive process. In the last few years, efforts have been dedicated internationally to design self-driving-laboratories, also called Material Acceleration Platforms (MAPs). MAPs integrate material synthesis, characterization and testing modules into circular workflows through automation and use artificial intelligence (AI) for efficient and autonomous experiment design, property prediction and data analysis.&#13;
We have established a MAP for corrosion research by automating diverse liquid operations, electrochemical testing and data evaluation, where the test results are interpreted via a machine learning (ML)-based backend. The workflows of the electrochemistry module are configured for electrodeposition of different alloys and subsequently performing electrochemical corrosion testing. The platform uses the results of the electrochemical tests to determine the next set of deposition parameters in a continuous and autonomous loop until the user-defined objectives are met.&#13;
In this project we used the MAP to design new multi-principal element alloys (MPEAs) as corrosion resistant electrode materials for H2O and CO2 electrolysis. One campaign contains a maximum of 144 runs. From each successful campaign top five leads and another five randomly selected materials proceed to upscaling either by electrodeposition at larger scale or as bulk ingots cast by means of arc-melting. With these samples, a detailed chemical and electrochemical characterization using surface analysis techniques was performed to validate the success of the MAP-based optimization. The presentation will give an overview of the design and build phases of our MAP, its modules and workflows. Moreover, we will summarize our results from the FeNiCrCuCoMo MPEA system.</abstract>

    <title language="eng">Effect of PAA-induced surface etching on the adhesion properties of ZnO nanostructured films</title>
    <abstract language="eng">Zinc oxide - polymer interfaces are known to exhibit interesting properties regarding molecular adhesion. This work is aimed at the investigation of the effect of the morphology and surface chemistry on the macroscopic adhesion of a model epoxy-based adhesive to nanorod (ZnO NR) and nanocrystalline (ZnO NC) ZnO-modified surfaces. Both ZnO films have been prepared using hydrothermal synthesis on hot-dip galvanized steel (HDG) surfaces by varying the precursor chemistry in order to control the film morphology. Poly (acrylic acid) (PAA) was used to improve the interfacial adhesion by modifying the morphology and surface chemistry of ZnO nanostructured films. The strong interaction of PAA from a dilute and neutral aqueous solution with the ZnO nanocrystallites was shown to significantly improve the interfacial adhesion by means of a nanoetching process.&#13;
It was shown that the wet peel-forces correlate well with the considered morphology and surface chemistry.</abstract>

    <title language="eng">Adhesion and corrosive delamination of epoxy films on chemically etched ZnMgAl-alloy coatings</title>
    <abstract language="eng">The effect of alkaline and acidic pretreatment steps on the surface chemical&#13;
composition and adhesion properties of ZnMgAl-alloy coated steel was&#13;
investigated by means of spectroscopic methods, scanning Kelvin probe (SKP)&#13;
and peel test measurements.The spectroscopic results indicate that the surface&#13;
film composition can be adjusted by the wet-chemical treatment. To study the&#13;
corresponding surface adhesive properties, the samples were coated with an&#13;
epoxy amine adhesive. Peel tests under humid conditions indicated an&#13;
increased interaction between the acidic pre-treated surface and the adhesive.&#13;
The results of the SKP analysis show that the acidic cleaned substrates have the&#13;
highest resistance to delamination, which can be explained by the shift of the&#13;
interfacial electrode potential.</abstract>

    <title language="eng">Chemical and electrochemical interaction mechanisms of metal-reducing bacteria with gold surfaces</title>
    <abstract language="eng">Bacterial biofilms are considered one of the salient contributing factors to the deterioration of metals and their alloys, occurring in virtually all environments and across various industrial systems. Considering the sheer magnitude of detrimental effects, it is of pertinent interest to elucidate the interaction mechanisms of sessile bacteria with metal and metal oxide surfaces to facilitate the development of efficient antifouling strategies. A common constituent of microbial communities within aquatic and sedimentary settings, the Shewanella genus consists of facultatively aerobic, Gram-negative bacterium which exhibit exceptional plasticity in respiratory capacities. During aerobic conditions, Shewanella utilizes oxygen as a terminal electron acceptor; conversely, under anaerobic conditions, it is able to undertake respiration by reducing alternative terminal electron acceptors such as oxidized metals via extracellular electron transfer mechanisms not yet thoroughly discerned.&#13;
The aim of this work is to explicate the mechanisms governing the initial bacterial adhesion and subsequent biofilm formation on metallic surfaces. To investigate this dynamic interplay, a combined approach has been followed which couples surface enhanced Raman spectroscopy (SERS) with electrochemical techniques using Shewanella sp. model biofilms. Gold nano-islands deposited on thin glass slides have been chosen as inert model substrates with good uniformity and high surface enhancement factor. Furthermore, the utilization of gold as substrate material not only allowed the differentiation of the sole effect of substrate polarization on bacterial attachment but also enabled a precise adjustment of the surface chemistry and surface energy by means of surface functionalization with organothiol self-assembled monolayers.&#13;
The results present the correlation of the primary settlement rate of bacteria on metallic substrates with the environmental parameters such as electrolyte composition and pH as well as surface-related properties like hydrophobicity/hydrophilicity and polarization. With the overall strategic goal of transferring this methodology to technical systems the results provide the fundamental basis for the bottom-up design of anti-fouling surfaces.</abstract>

    <title language="eng">Influence of the BF3·O(C2H5)2 on the corrosion resistance of hybrid silica sol-gel coatings deposited on flash-PEO-treated Mg alloy</title>
    <abstract language="eng">Achieving highly cross-linked sol-gel coatings to provide effective corrosion protection of Mg alloys remains a challenging task. The aim of this work is to evaluate the effect boron trifluoride diethyl etherate (BF3·O(C2H5)2) as catalyst to epoxy group in a GPTMS/TEOS/SiO2 sol and assesses its effect on the structure and corrosion resistance properties of Flash-PEO coated pre-treated Mg alloy. 29Si MAS NMR and 13C CPMAS-NMR demonstrated that (BF3·O(C2H5)2) efficiently promotes the epoxy polymerization of the GPTMS and the formation of a hybrid silica network. However, the amount of (BF3·O(C2H5)2) should be optimized to minimize the formation of undesirable byproducts such as ethyl ether terminal units. Therefore, GPTMS/TEOS/SiO2 sols containing different amounts of (BF3·O(C2H5)2) were synthesized and deposited onto the Flash-PEO coated Mg alloy, leading to bilayer systems with a total thickness of ⁓8 μm. The corrosion behavior of the bilayer coatings in 3.5 wt% NaCl solution was evaluated by electrochemical impedance spectroscopy (EIS) and Scanning Kelvin probe microscope (SKPFM). The results revealed that the barrier properties of the coatings with enhanced cross-linked structure showed impedance modulus (│Z│f:0.1 Hz) approximately four orders of magnitude higher than the bare magnesium alloy and two orders of magnitude higher than the F-PEO coated sample. A suitable compromise between (BF3·O(C2H5)2) amount and sol-gel film structure is required to obtain a more durable barrier coating capable to extend the protective lifespan of the magnesium alloy.</abstract>

    <abstract language="eng">Multi-principal element alloys (MPEAs) are disrupting methodologies in conventional alloy design, characterized by a singular dominant element dictating composition. The traditional optimization of the functional properties of alloys primarily relies on microalloying techniques. The advent of MPEAs has significantly broadened the chemical landscape available for exploration, approaching near-infinite possibilities. Consequently, innovative methodologies are imperative for discovering new alloys that exhibit properties customized for specific applications, simultaneously mitigating dependence on critical minerals. One promising approach for rapid screening of possible alloy chemistries and exploring the hitherto untouched regions of ternary, quaternary or higher order phase diagrams is the use of diffusion couples and multiples.&#13;
The present study focusses on the exploration of quaternary multi-principle-element alloys (MPEAs) using diffusion multiples. We established diffusion systems by combining an equimolar ternary alloy (FeNiCr) with single diffusing elements Mn, Mo and Ta. Using ThermoCalc® and DICTRA® simulations, we determined suitable parameters (temperature and diffusion time) that would lead to the formation of single-phase alloys and diffusion lengths (&gt;50 μm) that suit the application of high-resolution characterization methods. Microstructural and compositional characterization was performed via scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX), electron probe microanalyzer (EPMA) and correlated to local mechanical properties evaluated by means of nanoindentation. Selected compositions&#13;
from the diffusion couples were recast and homogenized to obtain bulk samples for the assessment of high-temperature and aqueous corrosion properties.&#13;
Our results indicate that the ThermoCalc simulations have a good predictive power for crystallographic phases for Mn and Mo containing MPEAs derived from the diffusion couples. Moreover, our data on FeCrNi-Ta system provides valuable experimental input for respective databases necessary for simulation of phase diagrams.&#13;
The presentation will summarize our methodology using diffusion couples as an efficient tool for exploring compositional spaces of MPEAs in the search for novel alloy chemistries and the results of our correlative study on the mechanical and corrosion properties of the selected quaternary systems.</abstract>

    <title language="eng">High CO2 reduction activity on AlCrCoCuFeNi multi-principal element alloy nanoparticle electrocatalysts prepared by means of pulsed laser ablation</title>
    <abstract language="eng">Noble metal-free nanoparticles (NPs) based on multi-principal element alloys (MPEAs) were synthesized using a one-step pulsed laser ablation in liquids (PLALs) method for the electrochemical reduction of CO2. Laser ablation was performed in pure water or poly-(diallyldimethylammonium chloride) (PDADMAC)-containing an aqueous solution of Al8Cr17Co17Cu8Fe17Ni33 MPEA targets. Transmission electron microscopy (TEM) measurements combined with energy dispersive X-ray (EDX) mapping were used to characterize the structure and composition of the laser-generated MPEA nanoparticles (MPEA-NPs). These results confirmed the presence of a characteristic elemental distribution of a core-shell phase structure as the predominant NP species. The electrocatalytic performance of the laser-generated MPEA-NPs was characterized by linear sweep voltammetry (LSV) demonstrating an enhanced electrocatalytic CO2 activity for PDADMAC-stabilized NPs. The findings of these investigations indicate that MPEAs have great potential to replace conventional, expensive noble metal electrocatalysts.</abstract>

    <title language="eng">High CO2 reduction activity on AlCrCoCuFeNi multi-principal element alloy nanoparticle electrocatalysts prepared by means of pulsed laser ablation</title>
    <abstract language="eng">Noble metal-free nanoparticles (NPs) based on multi-principal element alloys (MPEAs) were synthesized using a one-step pulsed laser ablation in liquids (PLALs) method for the electrochemical reduction of CO2. Laser ablation was performed in pure water or poly-(diallyldimethylammonium chloride) (PDADMAC)-containing an aqueous solution of Al8Cr17Co17Cu8Fe17Ni33 MPEA targets. Transmission electron microscopy (TEM) measurements combined with energy dispersive X-ray (EDX) mapping were used to characterize the structure and composition of the laser-generated MPEA nanoparticles (MPEA-NPs). These results confirmed the presence of a characteristic elemental distribution of a core-shell phase structure as the predominant NP species. The electrocatalytic performance of the laser-generated MPEA-NPs was characterized by linear sweep voltammetry (LSV) demonstrating an enhanced electrocatalytic CO2 activity for PDADMAC-stabilized NPs. The findings of these investigations indicate that MPEAs have great potential to replace conventional, expensive noble metal electrocatalysts.</abstract>

    <title language="eng">Chemical and electrochemical interaction mechanisms of metal-reducing bacteria with gold surfaces</title>
    <abstract language="eng">Bacterial biofilms are considered one of the salient contributing factors to the deterioration of metals and their alloys, occurring in virtually all environments and across various industrial systems. Considering the sheer magnitude of detrimental effects, it is of pertinent interest to elucidate the interaction mechanisms of sessile bacteria with metal and metal oxide surfaces to facilitate the development of efficient antifouling strategies. A common constituent of microbial communities within aquatic and sedimentary settings, the Shewanella genus consists of facultatively aerobic, Gram-negative bacterium which exhibit exceptional plasticity in respiratory capacities. During aerobic conditions, Shewanella utilizes oxygen as a terminal electron acceptor; conversely, under anaerobic conditions, it is able to undertake respiration by reducing alternative terminal electron acceptors such as oxidized metals via extracellular electron transfer mechanisms not yet thoroughly discerned.&#13;
The aim of this work is to explicate the mechanisms governing the initial bacterial adhesion and subsequent biofilm formation on metallic surfaces. To investigate this dynamic interplay, a combined approach has been followed which couples surface enhanced Raman spectroscopy (SERS) with electrochemical techniques using Shewanella sp. model biofilms. Gold nano-islands deposited on thin glass slides have been chosen as inert model substrates with good uniformity and high surface enhancement factor. Furthermore, the utilization of gold as substrate material not only allowed the differentiation of the sole effect of substrate polarization on bacterial attachment but also enabled a precise adjustment of the surface chemistry and surface energy by means of surface functionalization with organothiol self-assembled monolayers.&#13;
The results present the correlation of the primary settlement rate of bacteria on metallic substrates with the environmental parameters such as electrolyte composition and pH as well as surface-related properties like hydrophobicity/hydrophilicity and polarization. With the overall strategic goal of transferring this methodology to technical systems the results provide the fundamental basis for the bottom-up design of anti-fouling surfaces.</abstract>

    <title language="eng">A 30-year-old diesel tank: Fungal-dominated biofilms cause local corrosion of galvanised steel</title>
    <abstract language="eng">The increased use of biodiesel is expected to lead to more microbial corrosion, fouling and fuel degradation issues. In this context, we have analysed the metal, fuel and microbiology of a fouled diesel tank which had been in service for over 30 years. The fuel itself, a B7 biodiesel blend, was not degraded, and—although no free water phase was visible—contained a water content of ~60 ppm. The microbial community was dominated by the fungus  Amorphotheca resinae, which formed thick, patchy biofilms on the tank bottom and walls. The tank sheets, composed of galvanised carbon steel, were locally corroded underneath the biofilms, up to a depth of a third of the sheet thickness. On the biofilm-free surfaces, Zn coatings could still be observed. Taken together, A. resinae was shown to thrive in these water-poor conditions, likely enhancing corrosion through the removal of the protective Zn coatings.</abstract>
