Summary: Thermal modification is an effective method to improve the color homogeneity of black locust wood, but the darkening is mainly caused by changes in extractives and the formation of new chromophores. Hemicellulose degradation and partial cellulose degradation also contribute to color changes. Lignin can undergo condensation reactions at higher temperatures, leading to the formation of additional chromophores. Statistical analysis confirmed that temperature is a significant factor affecting wood surface color.

Summary: In the wood furniture and flooring industry, the protective and aesthetic properties of the final product often rely on the coatings applied to the wood surface. UV-cured coatings are preferred for flat surfaces due to their advantages of fast curing times, low VOC emissions, low energy consumption, and high crosslinking densities. Understanding the behavior of protective coatings under wear and deterioration is crucial for enhancing the durability of interior wood products and improving overall product perception.

Summary: In this study, FTIR spectroscopy and mechanical analysis were used to monitor wood molecular straining and gain a better understanding of the micromechanical properties of thermally-treated wood. The results showed that as the thermal treatment temperature increased, the degradation of hemicellulose increased and cellulose microfibrils reorientation occurred. The study also found that the toughness of thermally-treated wood decreased or brittleness increased due to the decrease in shear slipping between cellulose microfibrils and the reorientation of microfibrils caused by hemicellulose degradation.

Summary: By using non-destructive Fourier Transform Infrared Spectroscopy, the authors successfully determined the molecular fingerprints of eukaryotes and prokaryotes from the 407Ma Rhynie chert fossil assemblage of Aberdeenshire, Scotland. This study demonstrates the usefulness of infrared spectroscopy in resolving the affinities of extinct organisms that cannot be resolved by morphology alone.

Summary: This study validated a model for the classification of wood species and a universal model for the rapid determination of cellulose, hemicellulose, and lignin using FTIR spectroscopy coupled with chemometrics. The results showed that the full spectra can be used to differentiate different species and identify infrared peaks associated with cellulose, hemicellulose, and lignin. In addition, the full spectra helped build a three species universal model for quantifying the principal wood chemical components. Therefore, the study demonstrated that FTIR-ATR, together with chemometrics, is a reliable method for discriminating wood species and determining wood chemical composition.

Summary: This paper proposes a novel approach for rapid breast cancer diagnosis using attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy. The technique allows direct analysis of tissue samples, saving time and resources compared to traditional methods. By analyzing the spectroscopic data with machine-learning models, accurate classification of cancerous and non-cancerous tissues can be achieved. The study demonstrates the potential of the proposed method for breast cancer diagnosis with a sensitivity of 74.2% and specificity of 78.3%.

Summary: The formation of metal soaps in oil paintings is a common issue that can alter the performance and appearance of the paint film, complicating cleaning methods. Studies have shown that acids from drying oil and natural resins can react with pigments to form carboxylate salts, impacting the behavior of the paint film. Additionally, surface varnishes containing terpenic acids may play a significant role in the formation and reactivity of carboxylates in paintings.

Summary: The study and restoration of a polychrome limestone statue presented conservation issues related to the polychromy on stone, requiring re-establishing cohesion among different polychrome layers and adhesion between the polychrome film and stone substrate. Various intervention materials were tested and a micro-acrylic resin was selected for its ability to penetrate pores, consolidate layers, and maintain color and permeability. Attention was also given to compatibility with cleaning methods, with the resin successfully applied after consolidation of the pictorial layers.

Summary: An analytical method based on ATR-FTIR and Py-GC/MS was developed to identify PVA-borax gel residues. The results showed that clearing the surfaces with organic solvents is necessary to ensure a good removal of gel residues. Py-GC/MS analyses in SIM mode are more sensitive and selective for detecting gel residues.
