Summary: This study surveyed the microbiome and its potential for biodeterioration on unpreserved Lan Na mural paintings in Sean Khan temple, Thailand. The results showed that the main microbial groups causing deterioration were the salt-tolerant archaeon Halococcus, the bacterial genus Crossiella, and the fungal genus Candida. The deterioration mainly affected calcium compounds in the painting substrate, and certain fungi and bacteria were able to dissolve these compounds. The preservation effort should focus on the plaster component of the mural painting.

Summary: This article discusses four panel paintings depicting the birth of Christ, which were found to have a muted color palette. The investigation focused on analyzing the materials, painting technique, and degradation issues that affected the original paintings and changed the viewer's perception. The study identified the pigments used and detected chemical and physical alterations that caused color changes. The presence of moisture and reactions between pigment and binder played a central role in the long-term behavior of the paint film. Understanding these degradation processes is crucial for the interpretation and preservation of these artworks.

Summary: This article examines the long-term development of seigneurial governance within the principality of Guelders in the Low Countries. By analyzing four quantitative cross-sections, the conclusion is drawn that seigneurial governance remained stable in late medieval Guelders due to active collaboration between princely administrations, lords, and local communities, forming an integrated yet polycentric state. This challenges the prevailing narrative of progressive state centralization in pre-modern state formation historiography.

Summary: This paper focuses on finger rings that were made using the reverse glass painting technique, which became popular in Europe by the end of the 16th century. Specifically, it examines nine finger rings that feature a depiction of the forget-me-not flower. The paper aims to contextualize the use and function of these rings in the realms of love, friendship, and faith, and also explores their connection to the tradition of German literature and texts through the use of the V(G)MN or FGMN symbols.

Summary: The potentials of producing ceramic materials Ta4HfC5 and Ta4HfC5-30 vol% SiC at relatively low temperatures (1700 and 1800 degrees C) were studied through reactive spark plasma sintering of highly dispersed powders Ta2O5-HfO2-C and Ta2O5HfO2-C-SiC. The introduction of silicon carbide not only stimulated the consolidation process and the formation of a solid solution with Ta4HfC5 composition, but also increased the oxidation resistance of the carbide ceramics. Oxidation resistance of the obtained ceramic materials was evaluated by thermal analysis and exposure to laser radiation in atmospheric air.

Summary: The oxidation process of low-layer Ti2CTx MXene was studied using in situ Raman spectroscopy on an Al2O3/Pt sensor substrate. The oxidation was observed to begin at 316 degrees C on the Al2O3 ceramic parts, while for platinum, it only occurred at 372 degrees C. At 447 degrees C, the initial MXene film was completely oxidized to TiO2. The microstructure and dispersity of the MXene films were investigated using scanning electron microscopy and atomic force microscopy. The films exhibited chemoresistive responses to various gases at room temperature and 50% relative humidity, with the highest sensitivity observed for NH3. The gas-sensitive properties were shown to be favorably affected by the partial oxidation of Ti2CTx MXene.

Summary: Currently, MXenes, a new class of 2D nanomaterials, have attracted great scientific and applied interest due to their broad application prospects, including their potential as effective doping components for MOS sensor receptor materials. In this study, we investigated the influence of adding 1-5% multilayer two-dimensional titanium carbide Ti2CTx, obtained through etching Ti2AlC with NaF solution in hydrochloric acid, on the gas-sensitive properties of nanocrystalline zinc oxide synthesized by atmospheric pressure solvothermal synthesis. The results showed that all the materials obtained exhibited high sensitivity and selectivity towards 4-20 ppm NO2 at a detection temperature of 200 degrees C. The sample with the highest Ti2CTx dopant content showed the best selectivity towards NO2, and an increase in MXene content led to increased responses to nitrogen dioxide, possibly due to factors such as an increase in specific surface area, the presence of MXene surface functional groups, and the formation of Schottky barrier at the component interface.

Summary: The in-situ Raman spectroscopy oxidation of accordion-like V2CTx MXene resulted in the formation of a nanocomposite of V2CTx/V3O7 composition. Physical and chemical analysis methods were used to study the elemental and phase composition, as well as the microstructure of the synthesized V2CTx powder and MXene film, and the V2CTx/V3O7 nanocomposite obtained at a minimum oxidation temperature of 250 degrees C. The obtained V2CTx and V2CTx/V3O7 films showed increased sensitivity to ammonia and nitrogen dioxide, respectively, at room temperature and zero humidity. The V2CTx/V3O7 composite material exhibited a higher response value for multiple analytes (including humidity) and a change in their detection mechanisms compared to the individual V2CTx MXene.

Summary: This work focuses on the formation of thin V2O5 film by pen plotter printing using a hydrolytically active precursor called vanadyl alkoxyacetylacetonate. The functional ink used for printing is a solution of a vanadyl butoxyacetylacetonate complex with 87% butoxyl groups. The resulting oxide film consists of nanorods with a thickness of 35-75 nm and a length of 120-285 nm, and has a crystallite size of 54 +/- 4 nm. The material shows a high content of defects and the main conductivity mechanism is correlated barrier hopping of the charge carriers, with a conductivity activation energy of 0.24 eV.

Summary: In order to address the increasing volume of plastic, plastic recycling technologies are being actively developed and implemented. These technologies require new analytical tools to control the quality of the recycled polymers for further integration into production processes. In this study, a rapid and selective quality assessment method for high-density polyethylene polymer materials is proposed, using an electronic nose with aluminum doped zinc oxide sensing material in combination with the RandomForestClassifier machine learning tool. The electronic nose demonstrated a good correlation between vector signal and emitted volatile compounds, with an accuracy of over 98.5% when discriminating between primary and secondary plastics. The addition of zeolites to recycled plastic was found to decrease the occurrence of off-odors.
