Summary: EC-SOERS is a new phenomenon that enhances the Raman signal during the oxidation of a metal surface. Studies show that carbonyl and carboxyl groups are necessary to observe this phenomenon, with a delocated charge being important factor. Evaluating the enhancement factors for different molecules with highly delocated charge and a carboxyl group sheds more light on the interaction of molecules with the electrochemically generated SOERS substrates.

Summary: This study presents the optical response of spherical CdSe nanocrystals using SERS and TERS techniques, achieving significant enhancement of optical phonons by selecting appropriate plasmonic substrates. Combining Raman scattering with atomic force microscopy offers nanoscale spatial resolution for investigating phonon properties. Gap-mode TERS further enhances Raman scattering of CdSe NCs' optical phonon modes with nanometer spatial resolution, providing new pathways for optical characterization and phonon spectrum details at the nanometer scale of single semiconductor nanostructures.

Summary: The complexity of substances in environmental water bodies is leading to severe ecotoxicological problems. Evaluating water quality accurately based on the species and concentration of chemicals alone is difficult due to the intricate interaction among various chemicals. Therefore, the acute toxicity evaluation of water is of significant importance in environmental monitoring, especially in emergency situations. This study proposes a SERS approach to evaluate the acute toxicity of fresh water for the first time, using indole as an indicator. It demonstrates the feasibility of using SERS-based microbial sensors to assess acute toxicity in water.

Summary: The increase in inelastically scattered signal observed in Surface-enhanced Raman spectroscopy (SERS) is attributed to different mechanisms. The study revealed a transition to pure electromagnetic enhancement when molecules are separated from the metal surface. By preventing direct contact between molecules and the metal surface, the electronic (chemical) enhancement mechanism can be switched.

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.
