Summary: This paper reports on the spectral characterization of porphyrins and terpenoids in different vegetable oils, classifying them using a PCA-SVM model. The study analyzed the effects of oil types and processing technology on spectral differences, finding that chlorophyll and β-carotene were the main contributors to the fingerprint information in the spectral techniques. Extra virgin olive oil obtained by physical cold pressing had the highest content of porphyrins and terpenoids, indicating the strongest activity.

Summary: A mid-infrared photothermal-fluorescence in situ hybridization (MIP-FISH) platform is developed for simultaneous identification and metabolic analysis of microbes with single-cell resolution and high throughput. By improving MIP imaging, isotopically labeled compounds incorporated into proteins of individual bacterial cells can be sensitively detected, while FISH labeling with rRNA-targeted probes enables the identification of the analyzed cells. In proof-of-concept experiments, MIP-FISH successfully discriminates and identifies labeled bacterial cells within a complex human gut microbiome sample based on the clear spectral red shift in the protein amide I region caused by incorporation of 13C atoms from 13C-labeled glucose. This study opens up new opportunities for single-cell structure-function analyses in microbiology.

Summary: Binary and ternary cocrystals in the ternary cocrystal system of isoniazid-nicotinamide-succinic acid were prepared by solvent evaporation and grinding methods, and characterized by terahertz time-domain spectroscopy (THz-TDS). The formation of hydrogen bonds in the cocrystal was simulated by density functional theory (DFT), with good agreement with the experimental result. Raman spectroscopy was used to analyze the formation process of ternary cocrystal, and the changes of characteristic peaks in the corresponding Raman spectra provided process information of cocrystal formation.

Summary: This study presents a combination of surface enhanced Raman spectroscopy (SERS) and independent component analysis (ICA) for detecting trace antibiotics in aquacultures. The optimized ICA method effectively decomposes the measured SERS spectra and accurately identifies target antibiotics in mixtures at a concentration of 10(-6) M with correlation values of 71-98% to the reference molecular spectra. The measurement results from a real-world sample demonstration suggest the promising potential of this method for antibiotic monitoring in aquatic environments.

Summary: Iridescence is found in a wide range of organisms, with birds displaying a variety of iridescent structural colors in their feathers. The development of iridescent and non-iridescent feathers in superb starlings involves differences in the arrangement and composition of melanosomes, and gene expression related to pigmentation, metabolism, and cellular organization. Iridescent feathers may form through a combination of passive self-assembly and active processes involving gene expression.
