Summary: A novel flat microfiltration membrane was prepared by the compression method using cement and sucrose as a pore-forming agent for catalytic ozonation of iopamidol (IPM). The membrane structure contained various metal oxides and alkaline hydration products rich in hydroxyl groups. Hydroxyl radicals (center dot OH) were found to play a crucial role in the degradation process of IPM, which included amide hydrolysis, amino oxidation, and dehydrogenation.

Summary: During ozonation, the concentrations ratios of hydroxyl radicals, superoxide radicals and ozone remain constant, indicating the potential non-negligible role of superoxide radicals in the degradation of certain micropollutants with similar or higher reactivity compared to hydroxyl radicals. The proposed chemical kinetic model accurately simulates the abatement efficiencies of ozone-resistant micropollutants by considering the contribution of superoxide radicals, providing a valuable tool for predicting micropollutant removal during ozonation.

Summary: This study systematically investigated the catalytic ozonation of oxalic acid and phenol using normal spinel-ZnFe2O4 and inverse spinel-MnFe2O4 as catalysts. MnFe2O4 showed better catalytic activity for oxalic acid decomposition while ZnFe2O4 performed better for phenol decomposition. The different catalytic mechanisms were attributed to the higher electron transport capacity of MnFe2O4 and the more abundant surface hydroxyl groups of ZnFe2O4.

Summary: Hydroxyl radical-dominated oxidation plays an important role in catalytic ozonation, but the mechanism of ozone-based oxidation processes is still unclear. In this study, transitional metal single-atom catalysts were prepared to accelerate ozone decomposition and generate highly reactive hydroxyl radicals for the oxidative destruction of organic pollutants. Experimental and theoretical results showed that the oxidation of oxalic acid occurred dominantly in the bulk phase for the Mn catalyst, while a combination of bulk phase and surface reaction was observed for the Co catalyst. The differential adsorption of O3 and coordination configuration of a key intermediate species, *OO, were proposed to be responsible for the observed differences in oxidation mechanisms and kinetics.

Summary: This study assesses the reaction kinetics, degradation mechanisms, and associated toxicity of the neonicotinoid insecticide clothianidin (CLO) during ozone-based oxidation in water. The results indicate that the degradation is mainly attributed to indirect mechanisms rather than direct degradation pathways. The presence of dissolved organic carbon (DOC) in water matrices hinders the achievement of high CLO removal, while carbonate alkalinity has a minimal effect on the process efficiency. The study also identifies the major transformation products of CLO and reveals their decreased toxicity compared to the parent compound. These findings suggest that ozonation is a suitable technology for the abatement of CLO and its associated toxicity in aqueous matrices.

Summary: Ozone-based microbubble technology demonstrated higher efficiency in oxidizing DMSO compared to conventional ozone millibubbles, with further improvement achieved by coupling with H2O2. While the generation of center dot OH from a certain amount of H2O2 had a positive effect, an excessive dosage had a negative impact. The TOC removal efficiency of ozone microbubbles was significantly better than that of ozone millibubbles.

Summary: Superoxide radicals (O-2(center dot-)) are important chain carriers in the radical chain reaction during ozonation, promoting the decomposition of ozone (O-3) to hydroxyl radicals ((OH)-O-center dot). This study used a probe compound and kinetic modeling to evaluate the role of O-2(center dot-) for O-3 decomposition during ozonation of synthetic solutions and natural waters. The results showed that O-2(center dot-) plays a critical role in promoting O-3 decomposition, with its contribution ranging from 45-70% depending on water composition.

Summary: The role of surface hydroxyl on a catalyst in the decomposition of O3 during heterogeneous catalytic ozonation is important but inadequately studied. This study used hydroxyl-rich goethite (a-FeOOH) as a catalyst for the ozonation of ibuprofen (IBP) and successfully adjusted the state of the hydroxyl groups on the catalyst surface through heating and changing pH. The results showed that a-FeOOH effectively degraded and mineralized IBP during ozonation, primarily promoting the decomposition of O3 into center dot OH. The study identified four types of hydroxyl groups on the catalyst surface and determined that neutral vacancy hydroxyl was the main functional hydroxyl for ozone catalysis. A proposed mechanism involves the decomposition of O3 into center dot OH on the surface hydroxyl.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
