Summary: In recent decades, Mars has been extensively studied as a potential host for life through on-site missions and observations. Space Agencies have conducted experiments on living organisms to understand their behavior in extraterrestrial conditions and to develop techniques for identifying biosignatures remotely. This study focused on the radioresistant cyanobacterium Chroococcidiopsis, investigating its response to radiation stress using Raman spectroscopy, Fourier Transform InfraRed (FT-IR) and Terahertz Time Domain spectroscopy (THz-TDs), which demonstrated the suitability of these techniques for future space missions.

Summary: In this study, chemical images were obtained by analyzing the inter- and intramolecular interactions in PHB/PLLA blends during isothermal melt crystallization using in situ ATR FT-IR spectroscopic imaging. The peak position of spectral bands reflected changes in these interactions and provided spatial distribution information. This work demonstrates the potential of in-situ ATR FT-IR spectroscopic imaging in visualizing different types of inter- or intramolecular interactions in multicomponent polymer systems.

Summary: Conventional methods for measuring deuterium concentration in body fluids involve isotope ratio mass spectrometry or FT-IR spectroscopy. This study explores an alternative method, ATR FT-IR, which allows for faster analysis with smaller sample volumes. The ATR FT-IR method demonstrated high precision in measuring deuterium in plasma, making it suitable for use in pediatrics where minimal blood sampling is required.

Summary: The determination of green pea and peanut adulteration in pistachio was studied using portable Fourier transform mid-infrared (FT-MIR) and Fourier transform near-infrared (FT-NIR) spectroscopy. Both spectrometers showed high performance in predicting adulterant levels, with FT-NIR spectrometer providing more precise results. These portable spectrometers have the potential to be alternative methods for real-time surveillance of green pea and peanut adulteration in pistachio, with FT-NIR spectrometer being the preferred choice.

Summary: The decomposition of ethanol over two Pd/Al2O3 catalysts was investigated using transmission FT-IR and ATR-IR spectroscopies. The regularity of Pd particles and initial Pd oxidation state were found to significantly impact the products formed, with ethanol oxidation to acetates being the kinetically favored reaction path. The presence of a solvent also dampened the decarbonylation process due to competition for surface sites.

Summary: This study provides new insights into the impact of position and number of substituents on the association and solubility of chlorophenols in CCl4. The research reveals that the equilibrium between intermolecular and intramolecular hydrogen bonding depends on the position and number of substituents, leading to variations in the extent of association. Theoretical calculations predict the most stable structures for different types of chlorophenols. The findings highlight the importance of solute associates' structure in determining solubility in inert or weakly interacting solvents.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
