Summary: This study used deep eutectic solvents (DESs) and surfactant solvents (SSs) to extract curcumin from turmeric residues (TRs). Choline chloride-propylene glycol (ChCl-Pro) showed the highest yield among the solvents used. The optimized extraction conditions achieved a curcumin yield of 54.2 mg g(-1), which was 1.31 times higher than using methanol as a solvent. The recovered curcumin exhibited antioxidant and acetylcholinesterase (AChE) inhibitory activities.

Summary: Feature extraction is crucial for deep-learning-based point cloud registration. Previous work often neglects shallow information, which is important for point cloud registration, as the neural network deepens. Shallow information represents the structure of the point cloud, while deep information represents its semantics. We demonstrate that incorporating shallow information in feature extractors positively impacts point cloud registration, as evidenced by experimental results on the ModelNet40 dataset.

Summary: A novel gold and copper bimetallic nanocluster-doped chitosan fluorescent composite film was successfully prepared by synthesizing gold and copper bimetallic nanoclusters emitting strong red fluorescence and utilizing a solution casting method. The composite film showed stable optical properties and could be stored for a long time. It exhibited strong and bright red fluorescence, making it suitable for real-time detection of Cr(vi), with a low detection limit (0.26 ppb) and satisfactory results in actual water samples. Its portability, high selectivity, and sensitivity also enable its extension to chemical and food detection.

Summary: The sensing application of citrate-functionalized gold nanoparticles (AuNPs) for the determination of L-cysteine in food and water samples was successfully demonstrated in this study. The aggregation of AuNPs enhanced the signal intensity of L-cysteine, resulting in effective absorption of electromagnetic radiation in the IR region for molecular vibration. The theoretical investigation and experimental results confirmed the interaction between AuNPs and L-cysteine molecules, leading to a shift in plasmon bands and aggregation of particles.

Summary: During the summer and winter periods of 2019-2020, we sampled fine mode ambient aerosols in three Himalayan glacial regions and evaluated their aerosol optical properties and radiative forcing efficiencies. We found that the highest absorption occurred in the near ultraviolet-visible wavelength range, with the central Himalayan glacial region showing the highest absorption. Black carbon had a greater contribution to light attenuation across a wide wavelength range, while brown carbon dominated absorption in the near UV-visible wavelengths. Our findings contribute to the understanding of carbonaceous aerosols and their impact on Himalayan glacier regions.

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.
