Summary: Recently, there have been advancements in using chemistry materials, such as TiO2/YMnO3 photocatalyst, for water purification to achieve the sustainable development goal of clean water and sanitation. TiO2/YMnO3 showed a higher photocatalytic activity and stability in the visible light region compared to TiO2. The enhanced performance is attributed to the formation of a TiO2/YMnO3 heterojunction, a narrower bandgap, and excellent charge carrier separation. This study provides insights into the green synthesis of TiO2-based photocatalysts for efficient degradation of organic dyes in water purification.

Summary: A simplistic solvothermal process was used to fabricate novel amorphous TiO2-BiOBr-Bentonite (A-TiO2-BiOBr-Bt) multidimensional photocatalysts in a practical and economically feasible manner. The stickiness of the A-TiO2-BiOBr-Bt wet cake and the low drying temperature make it a suitable composite for the fabrication of the photoreactive inner coating of water treatment containers. The A-TiO2-BiOBr-Bt photocatalyst with a mass ratio of 1:1:2 displayed high surface area, low bandgap, and low electron-hole recombination rate.

Summary: Bi2MoO6/TiO2 heterostructures were synthesized, which exhibited excellent visible-light absorption due to the presence of Bi2MoO6 nanosheets. The hierarchical structure composed of Bi2MoO6 nanosheets and TiO2 nanorods significantly increased the specific surface area and pore volume of the photocatalysts. The improved performance of the Bi2MoO6/TiO2 heterostructures in methylene blue degradation was attributed to the extended absorption of visible light, the large specific surface area of the hierarchical structure, and the enhanced separation efficiency of electron-hole pairs.

Summary: This study successfully addresses the challenges of charge transfer and light capture ability in multifunctional photocatalytic surfaces by constructing a sponge-like N,S-CQDs/Bi2MoO6@TiO2 film. The ternary film exhibits enhanced photocatalytic efficiency under visible and near-infrared light and effectively achieves photocatalytic sterilization of bacteria under visible light irradiation. The improved photocatalytic efficiency is attributed to the introduction of surface-functional N,S-CQDs and the construction of N,S-CQDs/Bi2MoO6@TiO2 Z-scheme system.

Summary: CD4(+) T cells play a crucial role in facilitating B cell immune protection provided by vaccines, while iNKT cells have been identified as an alternative source of help for B cells in mice. Nanoparticles containing alpha GC and S. pneumoniae polysaccharides activate murine iNKT cells and B cells, inducing robust immune responses and protection against deadly pathogens. However, the potential of these nanoparticles to eliminate B cells under certain conditions suggests the need for further clarification on iNKT cell interactions with B cells.

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.
