T1 - Non-invasive Analytic Tools in Studies of Manuscripts N2 - Physico-chemical analyses of writing materials offer insight into various questions associated with historical, cultural, and conservational aspects of manuscript studies. The catalogue of questions that can be addressed with these methods includes authenticity, dating, the attribution of various parts of the text to different scribes and the relation between the primary and secondary texts. Similarly, preservation of the manuscripts requires knowledge of the composition of the original materials versus old repairs, identification of damage, as well as recognition of natural aging and degradation processes. The material sciences can contribute data about the chemical compositions of the writing materials, elucidation of the techniques of their production and the absolute age of organic components, as well as characterization of corrosion effects, evaluation of conservation treatment, and monitoring of the preservation state.

In our presentation, we will begin by briefly reviewing the history of writing inks and discussing the three main categories: carbon-based inks, plant, and iron-gall inks. We will address their chronology, precursors, and mixed forms, as well as the features that allow for their identification. Then, we will present the techniques we use in ink analysis, whereby we would like to highlight the limitations, advantages, and disadvantages of each approach. Finally, we will discuss the new mass-spectrometric method based on micro-sampling and using atmospheric solid analysis probe (ASAP).

Con l'obiettivo di creare una storia dettagliata degli inchiostri neri, abbiamo elaborato un protocollo non invasivo per raccogliere dati statisticamente rilevanti sugli inchiostri da manoscritti datati e localizzati che coprono un ampio arco temporale e diverse aree geografiche. Il primo passo del nostro protocollo consiste nella selezione effettuata mediante riflettografia NIR e IRR. Le differenze ottiche tra gli inchiostri a base di carbonio, tannino e ferro-gallio sono meglio riconoscibili confrontando la loro risposta alla luce infrarossa: l'inchiostro a base di carbonio ha un colore nero intenso, l'inchiostro ferro-gallico diventa trasparente al di sopra dei 1400 nm e l'inchiostro a base di tannino scompare a circa 750 nm. abbiamo semplificato l'analisi utilizzando un piccolo microscopio USB con LED NIR (940 nm) e UV (395 nm) integrati, oltre a una fonte di luce bianca esterna. Confrontando le immagini sotto illuminazione bianca e nel vicino infrarosso, determiniamo la tipologia di inchiostro osservando i cambiamenti nell'opacità dell'inchiostro. In questo caso, gli inchiostri a base di carbonio non mostrano alcuna variazione di opacità quando illuminati con lunghezza d'onda NIR, mentre l'opacità degli inchiostri ferro-gallici cambia notevolmente e gli inchiostri tanninici diventano trasparenti. La nostra recente scoperta che gli inchiostri misti carbonio/ferro-gallici erano piuttosto diffusi nella tarda antichità e nell'alto Medioevo ci ha suggerito di tornare al metodo IRR convenzionale. Il secondo passo del protocollo prevede l'analisi micro-XRF per identificare i componenti inorganici dell'inchiostro. Nel caso degli inchiostri ferro-gallici, stabiliamo le impronte digitali, ovvero i rapporti caratteristici tra i componenti vitriolici dell'inchiostro e l'elemento principale, ferro.

Black writing inks in the period under consideration can be divided into three different classes: soot, tannin and iron-gall ink. The first one is a fine dispersion of carbon pigments in a water-soluble binding agent, the second one is a solution of plant extract from tree barks or gallnuts, while the third one contains both soluble and insoluble phases. This last ink is based on metal (iron) and is produced by a chemical reaction of soluble iron (II) with tannin in aqueous solution. Tracing the transition from writing inks based on carbon pigments (soot or charcoal), common in Antiquity to the iron-gall inks commonly used in the Middle Ages builds a focus of our investigative work at the BAM (Federal Institute of Material Analysis and Testing). In this context, we will discuss the results of the ink analysis obtained within the project “Crafting documents”.

Testing was conducted using the following techniques: 3-color photography, 3D-digital microscopy, scanning μ-X-ray fluorescence analysis (XRF), μ- Raman and FTIR spectroscopy. I will give a short explanation of the principles of the techniques and explain the choice of the instruments. The main task of our work at the BAM required characterization of the inks and comparison of the ink as well as the composition of parchment. For the ink characterization we have followed the protocol developed at the BAM. The standard protocol includes three non-invasive stages: a) near infrared photography (NIRR) to determine the ink type or its main component; b) X-ray fluorescence analysis (XRF) to determine a fingerprint for iron-gall inks or contaminants in carbon/plant inks; c) Raman spectroscopy if there is an indication that the inks are of a mixed type. For parchment characterization, we usually employ µ-XRF-mapping and FTIR to gain information on specific treatments experienced by the parchment during its preparation and history.

These works originate from the Punjab Hills in India (today Himachal Pradesh) and are commonly known as ‘Pahari miniature paintings’. The paper upon which these drawings are executed is said to have been produced in Sialkot during the eighteenth and nineteenth centuries when papermaking was an integral part of an overall regional economy correlated with other sectors such as agriculture and the textile industry. Although the term Sialkoti refers to identified papermills in Sialkot (now Pakistan), the paper from this region is yet to be subjected to a systematic study. This article therefore explores the paper(s) in question through macro- and microscopic observations of structure, pulp and fibres. The study of historical sources, complemented by the analysis of paper samples and fibre identification, has revealed that the pulp would have been prepared from a variety of manufactured products using different technologies, such as rags, cloth, mats, rope and other plant-based materials made from local bast fibres which, once tattered, were recycled to prepare the pulp. Microscopic study reveals that a variety of fibre combinations under different conditions and processing steps were used, in particular sunn hemp fibre (Crotalaria juncea L.), a plant species that has until now rarely been identified in historical paper. In addition, the presence of kenaf and jute fibres, as well as a significant quantity of cotton fibres, have also been demonstrated. To overcome the lack of comparative materials, our work was supported by a comparative study of several materials made from sunn hemp now held in the Ethnobotany Collection at Kew Gardens. Samples were taken from these materials and provided useful reference micrographs for the identification of the WML samples. The quality of the paper used by Pahari artists, as well as the raw materials available and their processing, are discussed in detail. Putting all the data, including technical and historical information into perspective, we conclude that the Pahari artists used a paper of inferior quality compared to other types of paper used for other purposes such as the creation of illuminated manuscripts in the Punjab plains. This study therefore provides useful analytical and material evidence that complements previous historical, technical and anthropological studies.

T1 - Multifunctional polyoxomolybdate ionic liquid coatings for mitigating microbiologically influenced corrosion N2 - Corrosion of metals and other materials in marine environments poses significant economic, operational, safety, and environmental challenges across the oil and gas industry, the renewable energy sector, and maritime infrastructure. Microbiologically influenced corrosion (MIC) accounts for a substantial portion of this corrosion, with sulfate-reducing bacteria (SRB) and methanogenic archaea (MA) being key contributors. Conventional methods such as cathodic polarization have proven insufficient in mitigating the colonization of corrosive microbial communities in real marine environments, requiring the development of alternative, broad-spectrum antimicrobial strategies to prevent such biofilm formation. Recently, molybdate has emerged as a potential alternative to traditional biocides and nitrate. Our hypothesis is polyoxometalate-ionic liquids (POM-ILs), which exhibit antimicrobial and anticorrosion properties, could have a broader spectrum of antimicrobial activity than demonstrated until now and could be capable of shielding and protecting sensitive metal surfaces from the extreme acidic environments produced by MIC microorganisms. Here we show how two prototype polyoxomolybdate-based POM-ILs, [(CH3(CH2)6)4N]2[Mo6O19] and [(CH3(CH2)6)4N]4[Mo8O26], demonstrated antimicrobial activity at microgram per millilitre concentrations, prevented biofilm formation on metal surfaces, and provided resistance to corrosive acidic environments. Furthermore, impedance measurements were commensurate with electron microscopy studies showing that POM-IL-coated brass coupons withstood extremely corrosive environments. These proof-of-concept results demonstrate how multi-functional POM-IL coatings represent promising MIC mitigation solutions by providing a hydrophobic acid-resistant and biocidal protective layer that prevents biocolonisation and acidic corrosion by MIC microorganisms.

Biofilms are known to form on different kinds of surfaces such as metal, concrete, and medical equipment. However, in some cases the effect of microorganisms on the material can be negative for the consistency and integrity of the material. Thus, to overcome the issues raised by MIC on a system, different physical, chemical, and biological strategies have been considered; all having their own advantages, limitations, and sometimes even unwanted disadvantages. Among all the methods, biocide treatments and antifouling coatings are more common for controlling MIC, though they face some challenges. They lack specificity for MIC microorganisms, leading to cross-resistance and requiring higher concentrations. Moreover, they pose environmental risks and harm non-target organisms. Hence, the demand for eco-friendly, long-term solutions is increasing as regulations tighten. Recently, attentions have been directed to the application of nanomaterials to mitigate or control MIC due to their significant antimicrobial efficiency and their potential for lower environmental risk compared to the conventional biocides or coatings. Use of nanomaterials to inhibit MIC is very new and there is a lack of literature review on this topic. To address this issue, we present a review of the nanomaterials examined as a biocide or in a form of a coating on a surface to mitigate MIC. This review will help consolidate the existing knowledge and research on the use of nanomaterials for MIC mitigation. It will further contribute to a better understanding of the potential applications and challenges associated with using nanomaterials for MIC prevention and control.

Understanding the materiality of Tibetan paper N2 - Paper, as a writing support, is an integral element of the materiality of Tibetan books together with the technologies of their production. Analysis of the material features of the paper used in Tibetan written artefacts can help us to unravel their provenance, which is often unknown. First, however, we need a relatively clear understanding of the characteristic features of paper produced within particular book cultures and geographical regions at particular periods of time. This chapter offers a starting point by discussing the general characteristics of paper that originated in Tibet. Drawing on macro- and microscopic studies, it highlights the wide variety of paper types that have been used as writing supports in Tibetan written artefacts, before examining in more detail the raw materials, papermaking technologies and processes, and writing surface preparations that might justify the descriptor ‘Tibetan’ and thus grant Tibetan identity to paper.

T1 - Materials and materiality as keys to understanding a map of Mount Kailash N2 - While graphic and linguistic content is central to the identification of maps and can provide insights into the concepts and systems of rules, ideas and beliefs that led to their production, the materials that constitute maps may speak about manufacturing processes, the provenance of raw materials, the practical and technical knowledge of the mapmakers, and the use of the maps. This contribution underscores how the materials employed in Tibetan maps reveal aspects of their context and trajectory. Furthermore, materiality, conceptualized as a convergence of matter and imagination, can yield even more profound insights into artefacts like maps. Through a detailed case study of a map of Mount Kailash in the tangkha format and a specialized material-scientific analysis of the colourants employed in its creation, this contribution explores how a map can ‘talk’ through its materiality. With this case study it will show how Tibetan Studies can benefit from interdisciplinary collaboration. Crossing the field’s traditional boundaries and working with other disciplines, we argue, is absolutely essential for serious research.

The Divine Names should be written • by a qualified scribe • who is ritually pure • in the presence of a minyan (10 adult Jewish men) • in an appropriate frame of mind • without being interrupted However, when these scrolls were written it would have been impossible to verify any of this after the fact. While we do not currently have any way to determine how recently the scribes had bathed, or what they might have been thinking as they wrote, we can now know much more about the inscription of the Divine Name than these scribes ever would have guessed. It is sometimes apparent from a visual inspection of the text that the Divine Name has been written in a second stage, from irregular letter kerning or a different ink colour. Using XRF, we have been able to discover more instances of a different ink used for the Name, and have shown that in some cases the secondary ink was also used to correct the main text, suggesting that the later writing was done by a master scribe who also proofread the entire scroll. Using a Brucker M6 Jetstream, it has been possible to produce elemental “heat maps” of whole paragraphs or even large sections of a parchment sheet. Using such large samples of text, we can usefully compare the levels of copper and zinc used to write individual letters or words despite their relatively low concentration, which permits very fine differentiation of the inks used. The techniques presented here would also be highly applicable to assessing ink degradation, as they are able to detect much smaller differences in ink composition than had previously been possible.

For this purpose, single reference gas atmospheres of 76 pure VOCs (liquid at room temperature) and a group of 10 SVOCs and VOCs (solid at room temperature) were generated using two generation procedures. By exposing the samplers to individual components, it was ruled out that interactions in a mixture have a influence on the uptake rate. Another aspect was to precisely describe the methodology and the resulting uncertainties, as there are gaps in the literature in this regard. The selection of the compounds was based on the findings of the preceding GerES V study for which data was missing or needed to be verified. In each experiment, a number of six passive samplers was exposed to the test gas atmospheres in dynamically operated exposure chambers for seven days. The sensitivity of the uptake rates of a group of 10 selected VOCs to variations in exposure time, ambient temperature, and air humidity in a multi-component reference gas atmosphere was investigated. Here, a decrease in the uptake rate with the exposure time could be observed stabilising from the fifth day of exposure onwards. A significant effect of temperature and humidity on the uptake rate was not apparent. The determined uptake rates exhibit uncertainties of < 20 % for 71 substances, and < 10 % for 51 substances which are also in good agreement with the literature, if already published elsewhere.

T1 - Material Characterisation of 19–20th Century Manuscripts from Northern Thailand N2 - Material analysis was carried out on four manuscripts from Northern Thailand, which included two palm-leaf manuscripts and two paper manuscripts. The two palm-leaf manuscripts MS 6 and MS 7 were found to have been written in the traditional method, wherein text was incised on the surface of the leaves, and then soot applied to the surfaces, confirmed by the identification of carbon ink. MS 7 additionally showed the presence of trace levels of iron in the ink, either from soot paste or from the stylus used for inscribing. The paper manuscript MS 3 was written in iron-gall ink, with sections written using a methyl-violet based ink while MS 4 was written in carbon ink. The paper used in the case of MS 3 was found to be machine made, while khoi fibres (Streblus asper) were used for making the paper used for MS 4. A combination of traditional and modern pigments, like molybdenum orange, was used for decorating the edges and cover. The results improved our understanding of these manuscripts in particular, and also provided us with insights about the rapid adoption of modern materials and their incorporation into the production of written artefacts from Northern Thailand in the late 19th and early 20th centuries.

Unlike Terma (Revealed Treasures), which are discovered texts often concealed for future revelation, the Zhangzhung Nyengyü has been transmitted in an unbroken line from teacher to disciple over centuries. This study, edited by Agnieszka Helman-Ważny, represents a pioneering interdisciplinary investigation into these rare and culturally significant objects. Through the integration of textual and iconographic analysis with material science methodologies – including the examination of paper, pigments, ink and script – the work offers new perspectives on the historical and ritual functions of tsakali. This innovative approach bridges important gaps in the study of Tibetan material culture and contributes meaningfully to our broader understanding of the religious, artistic and intellectual history of Tibet and the Himalayas.

N2 - We studied freshly collected, dried and herbarized leaf fragments of two palms, namely Borassus flabellifer L. and Corypha umbraculifera L., most commonly used for palm-leaf manuscript (PLM) production in South (S) and Southeast Asia (SE) in order to reveal differences in their phytolith assemblages. For each of the two palms, 25 leaf samples were taken from the two Indian states of Kerala and Tamil Nadu. Dried leaf material was obtained from the fresh one by drying the leaves in air. Herbarium samples were obtained from two independent herbaria, specimen origin comprises S and SE Asia with the main focus on South India and Sri Lanka. Additionally, 25 manuscripts made of Borassus flabellifer leaves and 25 manuscripts made of Corypha umbraculifera leaves were investigated for phytoliths. All manuscripts are preliminary dated back to between the 16th and the beginning of the 20th century CE; most of them assumedly were produced in S India (Tamil Nadu and Kerala), Sri Lanka, Burma or Indonesia. Phytolith assemblages significantly differed between fresh, dry and herbarized palm leaves in comparison to PLM material, both qualitatively and quantitatively (mean r2 = - 0.61 ± 9.3 for Borassus samples and r2 = - 0.75 ± 5.3 for Corypha samples, at p &lt; 0.001). Fifty-three phytolith types described for PLM material were not observed in any of the fresh, dry or herbarized palm-leaf samples. Geographical analysis of PLM-specific phytoliths suggests that the combination of those phytoliths could be region-related. In this paper, we prove that the methods of palaeoecological reconstructions based on detailed microscopy of the PLMs surface and phytolith analysis applied in combination with methods of mathematical and computer data analysis can contribute to answer the questions posed by material codicology by revealing lost manuscript production recipes and by studying manuscript provenance in terms of the geographical origin of the artefacts. Our approach can potentially open a new perspective for palaeoecological studies expanding their traditional scope and making them applicable to a new research field.

N2 - Earth construction materials, including earth from historical building stock, offer high potential in terms of their recyclability and sparing use of natural resources. Yet, only a few studies have been conducted on the levels of pollutants and the accumulation of salts in buildings from the historical building stock to enable an assessment of the potential for recycling. The aim of a preliminary study as part of the GOLEHM Initiative from WIR! is to use spot checks to review the recyclability of earth construction materials from historical buildings in terms of environmental impact and tolerance by users. This could provide indicators for the Central Germany region on which pollutants and structurally damaging salts can be expected in earth construction materials from the building stock and to what extent, allowing conclusions to be drawn on how to manage earth construction materials from historical buildings. Additionally, microbiological inspections of two sample buildings were performed to assess a potential contamination with mould.

The impregnation of porous materials with volatile organic compounds (VOCs) is a promising approach to produce ERMs. Different VOCs were used to impregnate various porous materials (mainly zeolites, activated carbons and a metal organic framework). The influence of different methodological parameters and material properties were studied to optimize the impregnation procedure and to find the best material/VOC combination. The impregnation procedure remains quite irreproducible, nevertheless, very good ERM candidates were identified. Two materials (zeolite 4 and AC 1 impregnated with n-hexadecane) showed a very stable emission over 14 days (<10 % change). Another material (AC 1 impregnated with toluene) showed a declining emission profile but with a very good in-batch reproducibility and a storage stability of up to 12 months.

Its complexity results not only from a variety of highly processed ingredients, which can be used in its production, but also from a variety of methods in which these materials are combined to form the fibrillar network referred to as paper. While material identification methods are well established in the analysis of historical papers, the identification of manufacturing technologies is still an under-researched topic, that requires the development of appropriate methods and measurement protocols. This paper reports on the results of a research project aimed at the application of synchrotron scanning small angle X-ray scattering (SAXS) method in the characterization of paper structure, with emphasis on the assessment of fibrillar orientation as a marker characteristic for different, historical papermaking technologies.

Around 517 million tons of mineral raw materials are required annually for the construction of buildings in Germany. At the same time, mineral construction waste was the largest material flow at 229.3 million tons (2020). The rates of construction and demolition waste (CDW) recycling have increased since 2000, especially for mineral waste. Nevertheless, the majority of recycled aggregates are used in technically largely unregulated applications (e.g. road construction). This downcycling leads to a loss of valuable resources for technically and economically valuable applications. The upMIN 100 research project is investigating the question of whether and to what extent recycled CDW is suitable as an additive an binder in earthen building materials. The focus is placed on grain sizes of < 2 mm, which are currently predominantly landfilled, as there are at present no regulations for their use in building products. The soil matrix of earthen building materials however, naturally contains of different grain sizes, whith < 2mm – 0,063 for aggregates and < 0.063 mm as a binder. Therefore, the focused grain sizes (sand, clay and silt) could have a high usage potential. In order to enable the use of CDW, the technical feasibility must be ensured, quality requirements for source materials (e.g. threshold values for pollutants in terms of health and environmental compatibility and hazardous substances) and permissible proportions of recycled aggregates must be defined. Two different building material developments (earth blocks and -plaster)were used to assess both, the technical feasibility as well the pollutant content of the recycled aggregate and its final emissions into the indoor air. For both materials two mixtures could be established, that also meet the mechanical specifications according to the DIN standard, such as the compressive strength. A method was developed to design material mixtures with a high amount of CDW that comply with the defined limit values. The mixtures reached a recycling rate of 28 % with high mechanical properties and 70 % with minimum strength requirements.

While colouring seems at first glance simply superficial ‘prettifying’ of maps, most maps were given colours for other reasons: colour is an important key to understanding the function and use of maps. The use of colours, the choice of where to assign them and the meaning given to them has accordingly never been static but has changed over time. In this context, the three aspects: colour system, colour scheme, and colour code are of particular importance. Material scientific analysis makes it possible to find out more about the material composition of colourants (pigments and dyes) on maps. The study of colourants provides insights into the production conditions and use of maps. Furthermore, it offers clues about colour changes and forms the basis for appropriate restoration concepts.

Wesentlich ist dabei die Verzahnung von philologischer und naturwissenschaftlicher Perspektive. Wesentlicher Bestandteil der Messungen bildet das sogenannte Homburger Folioheft. Weiterhin wurden Briefe und Manuskripte aus den Beständen der Württembergische Landesbibliothek sowie zwei eigenhändige Gehaltsquittungen aus dem Hessischen Hauptstaatsarchiv Wiesbaden untersucht. Zwei in mehreren Manuskripten klar unterscheidbare Tinten lassen sich mit einiger Wahrscheinlichkeit biografisch mit dem Zeitraum zwischen Hölderlins Rückkehr aus der Schweiz im April 1801 und seinem Weggang nach Frankreich im Dezember dieses Jahres in Verbindung bringen. Für den in den untersuchten Handschriften häufigsten Tintentyp liegen datierbare Belege zwischen Januar 1803 und März 1804 vor, anzunehmen ist seine Verwendung zwischen Oktober 1802 und Juni 1804. Er dominiert auch im Homburger Folioheft. Eine vierte mehrfach vertretene Tinte gebraucht Hölderlin nach seiner Übersiedlung von Nürtingen nach Homburg. Sie findet sich im Folioheft und in einigen Einzelhandschriften. Damit können die in der Forschung umstrittenen Fragen geklärt werden, a) ob dem Dichter das Homburger Folioheft bei seinem zweiten Aufenthalt in Homburg zur Verfügung stand und b) ob überhaupt Werkhandschriften aus dieser Zeit erhalten sind. Darüber hinaus lässt sich über die Röntgenfluoreszenzanalyse der Arbeitsstand in den untersuchten Manuskripten zum Zeitpunkt des Ortswechsels im Juni 1804 genau angeben.

A promising mitigation strategy involves thin, transparent films of polyoxometalate-based ionic liquids (POM-ILs) as chemical shields. Stone samples coated with acid-resistant, biocidal POM-ILs exhibited negligible corrosion when exposed to simulated acid rain, in stark contrast to the severe deterioration of unprotected samples. Additionally, their biocidal properties effectively prevent biofilm formation on coated surfaces. Following studies successfully explored the effectiveness of the coating against lampenflora growing in the Pommery Champagne cellar; and the long-term performance of POM-ILs under outdoor environmental conditions. So, POM-ILs have already demonstrated remarkable anticorrosion and antimicrobial properties against aerobic microorganisms and, being water-insoluble, do not leach into aquatic ecosystem. The current research project repurposes the POM-ILs, extending their application to metals, specifically targeting microbiologically influenced corrosion (MIC) in cultural heritage artefacts made of brass, carbon steel, cast iron, and bronze. This involves optimizing nanocoating adhesion to the metal surface and evaluating its protective efficacy against MIC caused by anaerobic microorganisms such as methanogenic archaea and sulfate reducing bacteria (SRB). This presentation will highlight POM-ILs as sustainable, high-performance nanocoatings for biocorrosion mitigation. It will showcase published success stories, discuss ongoing research and proof-of-concept results, and explore future prospects for these advanced materials in safeguarding metal infrastructure and artefacts across different industrial sectors as well as in the context of cultural heritage conservation.

Methanogenic archaea have emerged as key contributors to corrosion under anaerobic conditions, capable of directly interacting with metal surfaces via extracellular electron transfer. This presentation provides an overview of our recent work on identifying, characterizing, and mitigating MIC caused by methanogens. We focus on the genetic differentiation of methanogenic strains, highlighting a novel class of [Ni/Fe]-hydrogenases identified exclusively in corrosive methanogens to date. These enzymes may serve as molecular markers for MIC risk assessment due to their unique sequence and functional properties. Additionally, we explore strain-specific differences in hydrogenase glycosylation and correlate these with observed variations in corrosion severity, biofilm formation, microbial surface interactions, and potentially enzyme stability. These findings suggest glycosylation may play a previously underappreciated role in MIC dynamics. To mitigate MIC, we investigate polyoxometalate-based (POM) coatings—originally developed for protecting stone-based artifacts—which we now apply to metal surfaces. These multifunctional coatings effectively inhibit biofilm formation and microbial activity, offering a promising strategy for corrosion control. Furthermore, we have developed customized test systems that simulate realistic environmental conditions, including high-pressure settings and dynamic flow regimes with varying velocities. These platforms allow for controlled evaluation of microbial corrosion under conditions relevant to underground hydrogen storage and marine environments, where salinity, pressure, and microbial activity interact. Our findings demonstrate that integrating molecular diagnostics, surface engineering, and advanced simulation platforms provides new insights into MIC mechanisms and opens avenues for predictive diagnostics and sustainable corrosion control strategies in industrial applications.
