Summary: This article reports the structural evolution of three copper-hydride nanoclusters and investigates their surface vacancy defect to non-defect transformation. It was found that the stability of the clusters increases with structural adjustments. These findings are important for understanding the structure-property relationship of nanoclusters.

Summary: By designing a Pd/Cu2O/TiO2 ternary hybrid photocatalyst, high-efficiency and highly selective photocatalytic reduction of CO2 into CH4 is achieved, with a CH4 production rate of 42.8 mu mol g(-1) h(-1) and a selectivity of 99.5%. This is attributed to the consecutive multistep charge transfer between the Cu2O/TiO2 heterojunction and Pd in the hybrid catalyst, leading to a spatially separated electron-enriched surface (Pd) and hole-enriched surface (Cu2O) that contribute to the high conversion rate and selectivity of CH4.

Summary: The multistep thermal dehydration of calcium hydrogen phosphate dihydrate (DCPD) to form gamma-calcium diphosphate (gamma-CPP) via calcium hydrogen phosphate anhydride (DCPA) was analyzed. The process was separated into five partially overlapping steps through kinetic analysis. The features of each step varied with reaction conditions.

Summary: Ionotropic glutamate receptors (iGluRs) play an important role in neurons, with involvement in memory, neuronal development, and synaptic plasticity. Arabidopsis thaliana has genes comparable to human iGluRs, affecting plant growth and physiological activities. The evolutionary relationship between animal and plant glutamate receptors suggests a correlation, which can be utilized for early detection of neurodegenerative diseases. This review updates knowledge on Arabidopsis glutamate receptors, their evolution, functions, and expression, in comparison with iGluRs. Additionally, the use of FRET nanosensors for understanding neurotransmitter signaling via glutamate receptors in animals and plants is discussed.

Summary: Mesoporous materials are widely used in drug delivery field due to their high surface area and porosity. The interfacial interactions established with drug molecules are crucial for efficient drug loading and controlled release kinetics. These materials can also be used to optimize the design of implantable local-delivery devices or improve the accuracy of imaging techniques in clinical diagnosis.

Summary: The degradation of sulfamethoxazole (SMX) through the peroxymonosulfate (PMS) activation by flower-like Fe3S4 was investigated. The flower-like Fe3S4 showed the best performance with the highest reaction stoichiometric efficiency. Non-radical singlet oxygen was found to participate in the catalytic oxidation of compounds in addition to the typical sulfate radical and hydroxyl radical.

Summary: This study investigated the CO3·-mediated oxidation of the frequently detected micropollutant ibuprofen. The results showed that the H atom abstraction pathway dominated the degradation process, regardless of the protonation state. Calculation of the reaction rate constant considering explicit solvent molecules yielded a value in agreement with the measured one. Significant charge transfer was observed from the CO3 center to the solvation shells. The study also constructed a contour plot demonstrating the contribution of CO3·- to the elimination of various micropollutants, highlighting the importance of CO3·- in sunlit surface waters.

Summary: This study proposes a method using ferroferric oxide technology to increase the production of medium chain fatty acids (MCFAs) in waste activated sludge. The results show that ferroferric oxide enhances the yield of MCFAs in the sludge and changes the distribution of key microorganisms, while also improving sludge dewatering and phosphorus removal.

Summary: Fe-Si-BAR showed excellent catalytic degradation performance towards the aromatic DBPs, especially 3,5-DiClSA, with the fastest degradation rate among the compared materials. The higher surface mobility of Fe-Si-BAR facilitated the degradation process by allowing easier oxidation of Fe2+ by H2O2, resulting in the generation of FeIV for the degradation of 3,5-DiClSA. The overall toxicity level of 3,5-DiClSA was significantly reduced after degradation by Fe-Si-BAR, making it a promising catalyst for the degradation of aromatic DBPs.

Summary: The scavenging capacities of ginkgolides and bilobalide, unique constituents of Ginkgo biloba extract, were investigated in silico. These compounds, with aliphatic carbon backbones and single C-C bonds, were found to be powerful scavengers with selectivity for alkoxyl and peroxyl radicals. The findings contribute to understanding the therapeutic action of G. biloba extract.

Summary: This study investigates the performance of sludge reduction through hydrodynamic cavitation (HC). The results show that HC treatment can decrease the concentrations of mixed liquor suspended sludge (MLSS) and mixed liquor volatile suspended solids (MLVSS), while promoting the solute chemical oxygen demand (sCOD) concentration and disintegration degree (DDsCOD) of sludge. HC treatment also leads to changes in particle size distribution and protein composition of sludge.

Summary: Experimental and theoretical studies show that the artificial allomelanin PDHN nanoparticles (PDHN-NP) have higher antioxidant efficiency compared to polydopamine nanoparticles (PDA-NP) due to catalytic cross-termination activity and a high reactivity with hydroperoxyl radicals (HOO), which is attributed to the presence of a H-bond network in PDHN-NP.
