How higher fungi respond to dsRNA is not known. We demonstrate that Magnaporthe oryzae (Mo), a globally significant crop pathogen, internalizes dsRNA across a broad size range of 21 to about 3000 bp. Incubation of fungal conidia with 10 ng/μL dsRNA, regardless of size or sequence, induced aberrant germ tube elongation, revealing a strong sequence-unspecific effect of dsRNA in this fungus. Accordingly, the synthetic dsRNA analogue poly(I:C) and dsRNA of various sizes and sequences elicited canonical fungal stress pathways, including nuclear accumulation of the stress marker mitogen-activated protein kinase Hog1p and production of ROS. Leaf application of dsRNA to the cereal model species Brachypodium distachyon suppressed the progression of leaf blast disease. Notably, the sequence-unspecific effect of dsRNA depends on higher doses, while pure sequence-specific effects were observed at low concentrations of dsRNA ( < 0.03 ng/μL). The protective effects of dsRNA were further enhanced by maintaining a gap of at least seven days between dsRNA application and inoculation, and by stabilising the dsRNA in alginate-chitosan nanoparticles.

Briefly, placing the blastospores in a hypotonic environment induced solute excretion, allowing significantly increased trehalose uptake during subsequent trehalose treatment. Conductivity changes and GC-MS analysis revealed that glycerol and lactate excretion is triggered in a hypotonic NaCl solution. After hypotonic + trehalose treatment, intracellular glycerol, lactate, and glucose levels increased, while other desiccation‑protective solutes remained unaffected. A fluorescence‑based single‑cell analysis of membrane stress and death during osmotic desiccation and rehydration showed that membrane stress and cell death were strongly amplified upon rehydration. Trehalose treatment reduced this amplification, while hypotonic + trehalose treatment minimised cell death and prevented a stress response during rehydration, though it increased membrane stress during desiccation. Newly formed germ tubes were identified as critical points of membrane failure during desiccation. Ultimately, the drying survival of blastospores was significantly improved by the hypotonic + trehalose treatment compared to untreated or trehalose‑only‑treated blastospores. In summary, this technique successfully enhanced blastospore desiccation tolerance and could be adapted to load cells with other solutes.}, language = {en} } @article{Wienbracke2025, author = {Wienbracke, Mike}, title = {„Verkauf" der Staatsangeh{\"o}rigkeit durch Mitgliedstaat („goldene P{\"a}sse") unionsrechtswidrig : [EuGH Urt. v. 29.4.2025 - C-181/23]}, series = {Neue Zeitschrift f{\"u}r Arbeitsrecht Rechtsprechungs-Report (NZA-Rechtsprechungs-Report ; NZA-RR)}, journal = {Neue Zeitschrift f{\"u}r Arbeitsrecht Rechtsprechungs-Report (NZA-Rechtsprechungs-Report ; NZA-RR)}, number = {7}, issn = {0949-7137}, pages = {416 -- 416}, year = {2025}, language = {de} } @article{MoorlachSedeHermannetal.2025, author = {Moorlach, Benjamin Willem and Sede, Ana Rocio and Hermann, Katharina M. and Levanova, Alesia A. and Poranen, Minna Marjetta and Westphal, Michael and Wortmann, Martin and Stepula, Elzbieta and Jakobs-Sch{\"o}nwandt, Desiree and Heinlein, Manfred and Keil, Waldemar and Patel, Anant V.}, title = {Interpolyelectrolyte complexes of in vivo produced dsRNA with chitosan and alginate for enhanced plant protection against tobacco mosaic virus}, series = {International Journal of Biological Macromolecules}, volume = {2025}, journal = {International Journal of Biological Macromolecules}, number = {Volume 306, Part 2}, publisher = {Elsevier}, issn = {0141-8130}, doi = {10.1016/j.ijbiomac.2025.141579}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-48855}, pages = {13}, year = {2025}, abstract = {We developed a formulation of long double-stranded RNA (dsRNA) using interpolyelectrolyte complexes (IPECs) composed of the biopolymers chitosan and alginate, in order to protect the dsRNA from biotic and abiotic factors.

Our approach relies on submicron particles with adjustable surface charge being either positive or negative. Following this approach, we obtained a high encapsulation efficiency of 94 \%. Subsequently, we investigated the influence of the charge ratio and total polymer content on the size, size distribution and ζ-potential of the IPECs. We discovered that formulating at low polymer concentrations ≤0.05 g/L with charge ratios of ≤0.9 (+/􀀀 ) and ≥ 1.25 (+/􀀀 ), respectively, produced <100 nm particles. Furthermore, the IPEC formulation protected dsRNA from enzymatic degradation by RNase III and micrococcal nuclease. In addition, we observed outstanding protection of formulated dsRNA from heat degradation. Experiments on Nicotiana benthamiana plants showed that formulated dsRNA offered protection against tobacco mosaic virus.

Studying innovation as a social context structured by power, we focus on 18 women innovators in innovation-driving environments. While these women appear to symbolize gender equality and embody contemporary postfeminist ideals of individualism, choice, and empowerment, many have simultaneously experienced (in)visibility and navigated unequal power structures throughout their careers. We investigate how these (in)visibility experiences are reconciled with the promises of postfeminism, exploring how postfeminist ideals are interpreted and negotiated by them to make sense of their own (in)visibility. While (in)visibility has traditionally been theorized in relation to norms and gendered power structures, our findings reveal how postfeminist discourses reframe visibility as an individualized, moralized imperative rooted in self-responsibility. Through this lens, we identify four postfeminist sense-making approaches: meritocratic visibility (embodying postfeminist ideologies), retraditionalized visibility (conforming to femininity), self-disciplined visibility (adapting to gender inequality), and collective-oriented visibility (challenging the status quo). These sense-making approaches highlight the various ways in which postfeminist sensibilities shape subjective experiences, often masking structural inequalities and allowing these to persist in contexts that claim to promote equal opportunities, such as the innovation environment.

Especially for frequently visited breakpoints, and even more so for production systems, it is crucial to keep performance overhead as low as possible. In this paper, we present an empirical study that compares the performance of four VMI breakpoint-implementation variants—EPT switching (SLAT view switching) with and without fast single-stepping acceleration, instruction repair, and instruction emulation—from two VMI applications (DRAKVUF, SmartVMI) with the XEN hypervisor on 20 Intel Core i processors ranging from the fourth to the thirteenth generation. Instruction emulation was the fastest method across all 20 tested platforms. Modern processors such as the Intel Core i7 12700H and Intel Core i9 13900HX achieved median breakpoint-processing times as low as 15 µs for the emulation mechanism. The slowest method was instruction repair, followed by EPT switching and EPT switching with FSS.

Despite its growing prevalence, a comprehensive conceptualisation of Work-Life-Blending is lacking. Our study addresses this gap by conducting a systematic review to define and clarify the construct, guided by Clark's (2000) work/family border theory. Research Question: Our study aimed to identify key factors and dimensions of Work-Life Blending, leading to a holistic conceptualisation. Specifically, our review seeks to answer: What are the key factors and dimensions of Work-Life-Blending, and how can they be integrated into a unified concept and definition? We aim to review the current state of knowledge, define and clarify the concept, and propose a future research agenda. Methodology: Following PRISMA guidelines (Liberati et al., 2009; Moher et al., 2009), we analysed 51 relevant articles from an initial pool of 1,400 references. A systematic review approach was used to synthesise existing literature and identify the main factors and dimensions associated with Work-Life Blending. Findings: Our findings revealed a diverse and multifaceted field, structured using Clark's (2000) key concepts. This framework provided deeper insights into the complex nature of the topic, highlighting significant diversification in the studies. Discussion and Implications: The study provides a strong foundation for further research on Work-Life Blending. By establishing a classification of key determinants, we offer a comprehensive framework for future studies, e.g., to explore which lifestyle principles can enhance work-life integration and address the challenges of modern work arrangements.

ISO 527-2 type 1A specimens were produced and tested for dimensional deviations and ultimate tensile strength (UTS). The results indicate that printing speed has a marked impact on both geometric precision and mechanical performance. The optimal speed of 300 mm/s provided the best compromise between dimensional accuracy and tensile strength for both filaments. At speeds below 300 mm/s, under-extrusion caused weak layer bonding and air gaps, while speeds above 300 mm/s led to over-extrusion and structural defects due to thermal stress and rapid cooling. Black PLA yielded better dimensional accuracy at higher speeds, with cross-sectional deviations between 2.76\% and 5.33\%, while natural PLA showed larger deviations of up to 8.63\%.

This stress results in altered community compositions incapable of mitigating the applied stressor within a two-week timeframe despite functional stability (inferred via metagenomics). Transcriptomics revealed a systematic heat shock response in the community and a highly active, metabolically versatile, uncharacterized anaerobic keystone species.

We propose a combined multivariate data processing framework that integrates LC-HRMS-based NTS data with other high-throughput data sets, exemplified here by 18S V9 rRNA and full-length 16S rRNA gene metabarcoding data sets. The power of data fusion is demonstrated by systematically evaluating the impact of treated wastewater (TWW) over time on an aquatic ecosystem through a controlled mesocosm experiment.

SLIDE-ASCA results indicate that temporal variability explains a much larger portion of the variance (74.6\%) than the treatment effect, with both contributing to global shared space variation (41\%).

However, the specific contribution of bacteria and their functional interactions with fungi in freshwater sediments have yet to be thoroughly explored. In the following study, we enriched organic matter through the addition of alder (Alnus glutinosa) leaves into artificial stream channels (AquaFlow mesocosms). We then investigated enzyme expression, metabolic pathways, and community composition of fungi and bacteria involved in the degradation of CPOM through metatranscriptomics and amplicon sequencing. Enzymes involved in the degradation of lignin, cellulose, and hemicellulose were selectively upregulated with increased organic matter. Analysis of ITS and 16S rRNA gene sequences revealed that during decomposition, fungal communities were predominantly composed of Basidiomycota and Ascomycota, while bacterial communities were largely dominated by Pseudomonadota and Bacteroidota. The similar gene expression patterns of CPOM degradation related enzymes observed between bacteria and fungi indicate potential functional interaction between these microbial groups. This correlation in enzyme expression may indicate that bacteria and fungi are jointly involved in the breakdown of coarse particulate organic matter, potentially through mutualistic interaction.

The influence of key process parameters, specifically laser power and scan speed, on the processability of CoCrFeNiCu-based high-entropy alloys produced by laser powder bed fusion additive manufacturing was investigated, with a focus of low laser power, which is critical for minimizing defects and improving the resulting microstructure and mechanical performance.

These evaluations were supplemented by in situ tensile experiments conducted within a scanning electron microscope to gain insights into the behavior of defects, such as hot cracks, during tensile testing.

An evaluation was conducted to ascertain the influence of the formulation process and the presence of the insert on the mechanical behavior with regard to tensile strength. The aluminum matrix was obtained from commercial and scrap alloys, elaborated by advanced methods of degassing and chemical modification. Meanwhile, the steel mesh reinforcement was cleaned, copper plated, and preheated to optimize wetting and, consequently, adhesion. The structural characterization was performed by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy analyses (EDX), which highlighted a well-defined interface and uniform copper distribution. The composite was produced by means of horizontal-axis centrifugal casting in a fiberglass mold, followed by cold rolling to obtain flat specimens. A total of eight tensile specimens were examined, with measured ultimate tensile strengths ranging from 78.5 to 119.8 (MPa). A thorough examination of the fractured specimens revealed a brittle fracture mechanism, devoid of substantial plastic deformation. The onset of failures was frequently observed at the interface between the aluminum matrix and the steel mesh. The use of SEM and EDX investigations led to the confirmation of the uniformity of the copper coating and the absence of significant porosity or interfacial defects. A bimodal distribution of tensile strength values was observed, a phenomenon that is likely attributable to variations in mesh positioning and local differences in solidification. A correlation was established between the experimental results and an analytical polynomial model, thereby confirming a reasonable fit.

Die Methodik basiert auf der Induktion eines Strukturwachstums in Bereichen, die entweder unzug{\"a}nglich oder zu d{\"u}nn sind. Um diese Bereiche zu identifizieren, wird ein Verfahren entwickelt, bei dem die Level-Set-Funktion entlang der Außenkonturen realistischer Werkzeuggeometrien interpoliert wird. Zur Induktion des Strukturwachstums wird regelm{\"a}ßig ein Potential definiert. Dieses besitzt innerhalb der Struktur gr{\"o}ßere Werte als außerhalb und {\"a}ndert sich normal zum Strukturrand linear. Eine Minimierung des auf dem Strukturrand vorliegenden Potentials wird in ein Strukturwachstum {\"u}berf{\"u}hrt. Dazu werden die Sensitivit{\"a}ten des Potentials bez{\"u}glich Verschiebungen des Strukturrandes ermittelt und mit den Entwicklungsgeschwindigkeiten der Level-Set-Funktion gekoppelt. Dadurch werden beide Fertigungsrestriktionen in eine gemeinsame mathematische Restriktion {\"u}berf{\"u}hrt und schließlich explizit in das Optimierungsproblem integriert.}, language = {de} } @book{GuddatWolf2025, author = {Guddat, Martin and Wolf, J{\"u}rgen}, title = {Grundkurs C++}, publisher = {Rheinwerk Verlag}, address = {Bonn}, isbn = {9783367104529}, publisher = {Westf{\"a}lische Hochschule Gelsenkirchen Bocholt Recklinghausen}, pages = {542 S.}, year = {2025}, language = {de} } @techreport{KueffmannMeickmannVeith2025, type = {Working Paper}, author = {K{\"u}ffmann, Karin and Meickmann, Lena and Veith, Tobias}, title = {Digitalisierung f{\"u}r eine besucherorientierte Innenstadt?}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-48059}, pages = {12 S.}, year = {2025}, abstract = {Thoughts about urban development via digital information channels and activators to increase visitor loyalty Online retailers and platforms use digital technologies of all kinds to offer customer-specific 24/7 services and have established new customer-centric, digitalized standards in retail and services.

This is especially true for the relationships between nutrients and bacteria, as phosphorus, nitrogen and organic carbon availability are known to influence bacterial population dynamics. It has been suggested that low nutrient conditions prompt the evolutionary process of genome streamlining. This process helps conserve scarce nutrients and allows for proliferation. Genome streamlining is associated with genomic properties such as \%GC content, genes encoding sigma factors, percent coding regions, gene redundancy, and functional shifts in processes like cell motility and ATP binding cassette transporters, among others. The current study aims to unveil the impact of nutrition on the genome size, \%GC content, and functional properties of pelagic freshwater bacteria. We do this at finer taxonomic resolutions for many metagenomically characterized communities. Our study confirms the interplay of trophic level and genomic properties. It also highlights that different nutrient types, particularly phosphorus and nitrogen, impact these properties differently. We observed a covariation of functional traits with genome size. Larger genomes exhibit enriched pathways for motility, environmental interaction, and regulatory genes. ABC transporter genes reflect the availability of nutrients in the environment, with small genomes presumably relying more on metabolites from other organisms. We also discuss the distinct strategies different phyla adopt to adapt to oligotrophic environments.

Freshwater salinization is a key stressor in these ecosystems that is predicted to be further exacerbated by climate change, which causes simultaneous changes in flow parameters, potentially resulting in non-additive effects on aquatic ecosystems. However, the effects of salinization and flow velocity on urban streams are still poorly understood as multiple-stressor experiments are often conducted at pristine rather than urban sites. Therefore, we conducted a mesocosm experiment at the Boye River, a recently restored stream located in a highly urbanized area in Western Germany, and applied recurrent pulses of salinity along a gradient (NaCl, 9 h daily of +0 to +2.5 mS/cm) in combination with normal and reduced current velocities (20 cm/s vs. 10 cm/s). Using a comprehensive assessment across multiple organism groups (macroinvertebrates, eukaryotic algae, fungi, parasites) and ecosystem functions (primary production, organic-matter decomposition), we show that flow velocity reduction has a pervasive impact, causing community shifts for almost all assessed organism groups (except fungi) and inhibiting organic-matter decomposition. Salinization affected only dynamic components of community assembly by enhancing invertebrate emigration via drift and reducing fungal reproduction. We caution that the comparatively small impact of salt in our study can be due to legacy effects from past salt pollution by coal mining activities >30 years ago. Nevertheless, our results suggest that urban stream management should prioritize the continuity of a minimum discharge to maintain ecosystem integrity. Our study exemplifies a holistic approach for the assessment of multiple-stressor impacts on streams, which is needed to inform the establishment of a salinity threshold above which mitigation actions must be taken.}, language = {en} } @inproceedings{BuettnerNeumannHernandezAcostaetal.2024, author = {B{\"u}ttner, Sebastian Thomas and Neumann, Paul and Hern{\´a}ndez Acosta, Luca and Reinhardt, Delphine and Prilla, Michael}, title = {Towards Privacy-friendly Telepresence Robots for Schoolchildren with Long-term Illnesses - User Needs of Relevant User Groups}, series = {Mensch und Computer 2024 - Workshopband.

In this work, we investigate the implications of a gender-biased robot that disadvantages women, which unfortunately is a bias in AI that is often reported. Our experiment shows that both men and women perceive the gender-biased robot to be unfair. However, our work indicates that women are more aware that a gender bias causes this unfairness.

However, they are often time-consuming to create and difficult to access during work. This paper introduces an approach that simplifies the creation of video tutorials in the workplace and promotes their use during work. By utilizing smart glasses, practitioners can record video tutorials during their daily work processes and utilize them for knowledge transfer to other employees without much additional effort. This offers the advantage of directly and easily sharing expertise in the workplace without being constrained by time or location. Given the intended simplicity of this approach, the question arises whether it creates video tutorials that help people in their learning. The paper presents a study that compares the effectiveness of knowledge transfer using these video tutorials against traditional personal training methods in the workplace. With 18 participants from the nursing and production sectors, we observed the training and learning outcomes of using video tutorials on smart glasses over multiple sessions, comparing them with personal training, which is considered the standard for practical onboarding. The study results indicate that learning with video tutorials does not significantly differ in terms of learning outcomes from traditional personal training methods. Overall, this study highlights the potential of video tutorials with smart glasses for knowledge transfer in workplaces, while also identifying challenges and opportunities for optimizing onboarding processes for employees.}, language = {en} } @inproceedings{BuettnerAlhajiKatariyaetal.2024, author = {B{\"u}ttner, Sebastian Thomas and Alhaji, Basel and Katariya, Kaushikbhai and Prilla, Michael}, title = {Interaction of Robot Speed and Distance in Human-Robot Collaboration: Impact on Human Trust, Safety, and Comfort}, series = {2024 33rd IEEE International Conference on Robot and Human Interactive Communication (ROMAN), 26-30 August 2024, Pasadena, CA, USA}, booktitle = {2024 33rd IEEE International Conference on Robot and Human Interactive Communication (ROMAN), 26-30 August 2024, Pasadena, CA, USA}, publisher = {IEEE}, isbn = {979-8-3503-7502-2}, issn = {1944-9437}, doi = {10.1109/RO-MAN60168.2024.10731236}, pages = {264 -- 271}, year = {2024}, abstract = {Abstract Robots are gradually being freed from their safety fences due to the advances in safety features integrated with most new robots.

Literature indicates that these factors influence whether humans perceive trust, safety, and comfort, which are essential components in the acceptance of robots by their end users. However, although speed and distance were intensively investigated in isolation, little is known about their combined effect. To this end, we conducted an experiment investigating the impact of the industrial robot arm's approaching speed and stopping distance on the users' trust, safety, and comfort while they were performing a collaborative task. Our results provide interesting insights into the implications of speed and trust.

However, our knowledge of interpersonal trust and trust in autonomous agents cannot be transferred directly to HRI.

Despite these advantageous properties, the machining of these composites presents formidable challenges due to their extremely high hardness. Grinding with diamond tools is commonly employed among the limited viable machining methods. However, the efficiency of this process is hindered by high grinding forces, elevated temperatures, and significantly high tool wear. Additionally, the surface integrity, form, and dimensional accuracy of the workpiece are compromised by the effects of tool wear and high cutting forces. To address these technological constraints in the grinding of SiC-bonded diamond materials, a laser-assisted grinding process has been developed. Ultra-short pulsed laser radiations were effectively utilized to induce material ablation with controlled structural damages, enhancing the productivity and efficiency of the grinding process through reduced grinding forces, temperatures, and tool wear. Furthermore, this study investigated the influence of grinding tools' specifications, design variations, and parameters on key aspects such as grinding forces, surface quality, and tool wear. Substantial reductions of up to 70\% in tangential grinding forces, 83\% in normal grinding forces, and a modest improvement in surface roughness achieved. The surface integrity analysis revealed a damage-free ground surface when utilizing laser assistance. Furthermore, there was a substantial enhancement in the grinding ratio (G-ratio), achieving an increase of up to 247\%, concurrently with a noteworthy improvement in the actual removal depth, reaching up to 99\%, when compared to conventional grinding processes. Compared to the utilized segmented metal bonded diamond grinding wheel, the vitrified bonded diamond grinding wheel induced lower grinding forces and higher actual removal rates.}, language = {en} } @article{SoniBeisserMladenovetal.2024, author = {Soni, Aashish and Beißer, Daniela and Mladenov, Emil and H{\"o}ller, Matthias and Wohlers, Inken and Nikolov, Vladimir and Magin, Simon and Mussfeldt, Tamara and Klein-Hitpass, Ludger and Cornforth, Michael N. and Loucas, Bradford D. and Rahmann, Sven and Iliakis, George}, title = {NGS Detects Extensive Genomic Alterations in Survivors of Irradiated Normal Human Fibroblast Cells}, series = {Radiation Research}, volume = {2024}, journal = {Radiation Research}, number = {203(1)}, publisher = {BioOne}, doi = {10.1667/RADE-24-00094.1}, pages = {37 -- 52}, year = {2024}, abstract = {Abstract It is thought that cells surviving ionizing radiation exposure repair DNA double-strand breaks (DSBs) and restore their genomes. However, the recent biochemical and genetic characterization of DSB repair pathways reveals that only homologous recombination (HR) can function in an error-free manner and that the non-homologous end joining (NHEJ) pathways canonical NHEJ (c-NHEJ), alternative end joining (alt-EJ), and single-strand annealing (SSA) are error-prone, and potentially leave behind genomic scars and altered genomes. The strong cell cycle restriction of HR to S/ G2 phases and the unparalleled efficiency of c-NHEJ throughout the cell cycle, raise the intriguing question as to how far a surviving cell reaches after repairing the genome back to its pre-irradiation state. Indeed, there is evidence that the genomes of cells surviving radiation treatment harbor extensive genomic alterations. To directly investigate this possibility, we adopted next-generation sequencing (NGS) technologies and tested a normal human fibroblast cell line, 82-6 hTert, after exposure up to 6 Gy. Cells were irradiated and surviving colonies expanded and the cells frozen. Sequencing analysis using the Illumina sequencing platform and comparison with the unirradiated genome detected frequent genomic alterations in the six investigated radiation survivor clones, including translocations and large deletions. Translocations detected by this analysis and predicted to generate visible cytogenetic alterations were frequently (three out of five) confirmed using mFISH cytogenetic analysis. PCR analysis of selected deletions also confirmed seven of the ten examined. We conclude that cells surviving radiation exposure tolerate and pass to their progeny a wide spectrum of genomic alterations. This recognition needs to be integrated into the interpretation of biological results at all endpoints, as well as in the formulation of mathematical models of radiation action. NGS analysis of irradiated genomes promises to enhance molecular cytogenetics by increasing the spectrum of detectable genomic alterations and advance our understanding of key molecular radiobiological effects and the logic underpinning DSB repair. However, further developments in the technology will be required to harness its full potential.}, language = {en} } @article{GeyerBoehmZellmeretal.2024, author = {Geyer, Marvin and B{\"o}hm, Christine and Zellmer, Florian and Meier, Julian and Ostermann, Rainer}, title = {Demonstrating Surface and Plasma Chemistry with a Nonthermal Atmospheric Plasma}, series = {Journal of Chemical Education}, volume = {2025}, journal = {Journal of Chemical Education}, number = {Volume 102, Issue 5}, publisher = {ACS Publications}, doi = {10.1021/acs.jchemed.4c00518}, pages = {2230 -- 2234}, year = {2024}, abstract = {Abstract A low-cost plasma nozzle/setup was developed to allow demonstrations, and it invites hands-on experimentation with nonthermal plasmas of air and other gases.

By applying ultrashort laser pulses to nickel felts, distinct surface morphologies were generated, including high-spatial-frequency laser-induced periodic surface structures (HSFL-LIPSS), irregular ablated surfaces, and hybrid structures. Surface area analysis revealed increases of up to 4-fold for LIPSS, 6-fold for hybrid structures (LIPSS+Ablation), and 9-fold for ablated surfaces compared to untreated fibers. Electrochemical testing showed reduced overpotentials for laser-treated samples, comparable to state-of-the-art electrodes despite the absence of catalyst layers. Overpotentials could be reduced by up to 6.5 \% at 10 mA cm-2 and by up to 9.6 \% at 100 mA cm-2 compared to the unprocessed felt. Notably, ablated structures, with the highest surface areas, exhibited microcavities that may entrap oxygen bubbles, limiting active site and reaction rates. The LIPSS structures demonstrated the lowest activation losses and highest current density (1.32 A cm⁻² at 2.0 V) due to their periodic morphology and enhanced electrolyte flow, representing a 17 \% improvement at 2.0 V compared to the untreated felts. Moreover, Tafel slopes down to 66 mV dec-1 denote a performant kinetic while oxidation charge measurements revealed pronounced peaks for laser-treated samples, with ablated surfaces achieving the highest charge of 16.76 ± 1.64 C cm⁻². Chronopotentiometry revealed the LIPSS structures showing the highest resistance to degradation among the structured samples. These findings suggest femtosecond laser nano structuring as a promising method to improve PTL performance. Further application of catalyst layers could amplify the electrochemical efficiency of these advanced materials.}, language = {en} } @article{LevenLimbergNolletal.2022, author = {Leven, Felix and Limberg, Johannes and Noll, Jessica and Ulbricht, Mathias and Ostermann, Rainer}, title = {Enhancing the phase change material properties by an energy-efficient one-step preparation method using organogelator-polyolefin composites}, series = {Materials Advances}, volume = {2022}, journal = {Materials Advances}, number = {No. 3, Issue 21}, publisher = {Royal Society of Chemistry}, issn = {2633-5409}, doi = {10.1039/d2ma00578f}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-47824}, pages = {7872 -- 7880}, year = {2022}, abstract = {The synergistic combination of various sorbitol-based organogelators with polyolefins allows the preparation of porous support structures for immobilized phase change materials (PCMs).

It also addresses informal institutions, such as women's role in society, the use of informal networks of connections and acquaintances, and gift-giving practices. Drawing on results from an online focus group discussion with women entrepreneurs in Georgia, we provide initial insights into the critical constraints and supporting factors that local women entrepreneurs experience. Based on the interrelation of institutions and women's entrepreneurship, we conclude that changes in formal institutions do not lead directly to changing informal institutions. Due to the lack of trust in formal institutions, women entrepreneurs are more likely to look for business development solutions outside the official frames, including illegal or unethical means of survival. Nevertheless, increased opportunities - induced by specific entrepreneurship policies and programs - encourage women to enter entrepreneurship.
