Summary: During the ozonation of wastewater, the hydroxyl radicals ((OH)-O-center dot) formed by the reactions of ozone (O3) with effluent organic matters (EfOMs) are crucial for degrading ozone-refractory micropollutants. However, the conventional tertButanol (t-BuOH) assay cannot accurately determine the (OH)-O-center dot yield. A competitive method, considering initiation and propagation reactions, was used to determine the actual (OH)-O-center dot yields (F) compared with the t-BuOH assay (f). The study found that the chain propagation reactions facilitated by EfOMs and fractions, expressed by the chain length (n), significantly impacted the (OH)-O-center dot formation.

Summary: This study theoretically examined the inactivation potency of quercetin and flavonoid catecholic metabolites 1-5 on HOO center dot, CH3OO center dot, and O-2(center dot-) under physiological conditions. The results showed that the catecholic moiety of quercetin and metabolites 1-5 played a crucial role in scavenging HOO center dot and CH3OO center dot. Metabolites 1 and 5 were identified as the most potent scavengers of HOO center dot and CH3OO center dot, respectively. Quercetin exhibited higher potency in inactivating HOO center dot and CH3OO center dot via single electron transfer. The SET reaction from the 3-O-phenoxide anion of quercetin represented the most contributing reaction path. Furthermore, all polyphenolic compounds studied showed potency in inactivating O-2(center dot-) through a concerted two-proton-coupled electron transfer mechanism. These findings suggest that metabolites with high radical scavenging potency and enhanced bioavailability may contribute to the health-promoting effects attributed to parent molecules.

Summary: This study investigates the transformation mechanisms, kinetics, and potential ecological risks of Ketamine (KET) degradation initiated by •OH/SO4•. The calculated results show that the H15 atom is more likely to be extracted, generating the most active dehydrogenated radical intermediate. The degradation products exhibit decreasing toxicity, but some remain at toxic levels. Additionally, the developmental toxicity, mutagenicity, and carcinogenicity of multiple transformation products increase compared with parent KET. This work contributes to understanding KET mineralization in liquid ecosystems and has implications for prospective industrial applications.

Summary: Crystallographic and computational studies suggest favourable interactions between polarizable arenes and halogen atoms. However, quantification of these interactions in solution has been hindered by the steric demands of the halogens. This study synthesized molecular balances and used H-1 NMR spectroscopy to quantify halogen-arene contacts in various solvents, revealing that the interaction trend is aligned with increasing exchange repulsion rather than dispersion.

Summary: This paper provides the first example of B-H...pi hydrogen bonding in a protein-ligand complex through high-resolution X-ray crystallography and quantum-chemical calculations. The study demonstrates that the B-H...pi interaction is stabilized by dispersion, followed by electrostatics. It also shows that the similar C-H...pi interaction is twice as strong, with a slightly smaller contribution of dispersion and a slightly higher contribution of electrostatics. Such insights will facilitate the rational design of future protein ligands, controlling these types of non-covalent interactions.

Summary: In this study, g-C3N4@CdS composites were used as sensing elements in a photoelectrochemical platform for the rapid, selective, and sensitive detection of L-cysteine. The system exhibited a wide determination range (5-190 μM), a very low detection limit (1.56 μM), fast response time, and good long-term stability (approximately 1 month). The g-C3N4@CdS composites provided better optoelectronic function than bare CdS materials due to their high photon-to-current conversion efficiency and excellent anti-photocorrosion properties. Additionally, without any separation procedures, low concentrations of L-cysteine were successfully detected in human urine samples, consistent with the results of chemiluminescence.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
