Summary: In this study, GdVO4:Eu3+ nanoparticles were investigated as prospective preventive nanozymes. The synthesized nanoparticles were characterized using various techniques. It was found that the nanoparticles exhibited individual crystalline spheroid structures in water solutions. Optical spectroscopy analysis revealed the presence of Fenton- and CAT-like reactions in these solutions. Furthermore, the nanoparticles were shown to protect rat hepatocytes from H2O2-induced oxidative stress.

Summary: The combination of dielectric barrier discharge (DBD) of non-thermal plasmas with a self-made photocatalyst effectively removed isopropanol (IPA). By varying synthesis conditions for the photocatalyst and observing factors such as initial IPA concentration, oxygen content, and catalyst dosage, optimal reaction efficiency was achieved.

Summary: This study reports a weak halogen bond type that induces the formation of supramolecular helical structures in both solid and solution states. Experiments with p-conjugated phenylalanine derivatives show that hydrogen bonds and halogen bonds respectively drive 21 helical packings, with small bond energies.

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: A humid atmospheric pressure plasma jet was used to treat an aqueous liquid, and the transport of hydrogen peroxide and hydroxyl from the plasma to the liquid was analyzed. Two in situ liquid diagnostics for each species were compared and validated. The results showed good agreement between the different methods used for detection.

Summary: Investigating the use of a fluorescence probe to detect increased Golgi ROS levels in hypertensive mice, evaluating the efficacy of antihypertensive drugs, and identifying ROS post-transcriptional modification sites on dihydrofolate reductase. This suggests a new therapeutic target for hypertension and the development of new antihypertensive drugs.

Summary: By enhancing the adsorption of H2O2 on a nitrogen-doped porous carbon (NPC) catalyst, highly active &•OH is generated for the electrochemical-activation of H2O2. The study provides new insight into the fabrication of efficient carbonaceous catalysts for the degradation of refractory organic pollutants.

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: The study reports a previously uncharacterized isomer of ethynylhydroxycarbene generated by high-vacuum flash pyrolysis, which can rearrange under irradiation to form a more stable conformer and eventually react to produce propynal. The experimental results are in good agreement with computational simulations at the CCSD(T)/cc-pVTZ and the B3LYP/def2-QZVPP levels.

Summary: By adjusting the Mo/Fe atomic ratio of Fe-Mo mixed oxides, simultaneous removal of SO2 and NOx can be achieved, with the catalyst having a Mo/Fe atomic ratio of 2.0 showing the highest activity and efficient removal at low H2O2 dosage. The redox pair of Fe2+/Fe3+ plays a crucial role in decomposing H2O2, while Mo species have a dual effect on catalytic activity, showing promise for the simultaneous removal of SO2 and NOx in coal-fired flue gas.

Summary: By selecting Fmoc-pentafluorophenylalanine as a model efficient gelator and studying its self-assembly in the presence of benzamide, a 1:1 co-crystal was obtained, which can form transparent gels in aqueous media. This crystal engineering-based approach can be used for modulating the properties of amino acid-based hydrogels and for the time-delayed release of suitable bioactive molecules.
