Summary: TiO2-based visible-light-sensitive nanomaterials have been extensively studied for photocatalytic applications. This study investigated the influence of extrinsic oxygen vacancies on the photocatalytic performance of TiO2-based charge-transfer complexes (CTCs). The results showed that increasing the concentration of extrinsic oxygen vacancies did not improve the photocatalytic performance of TiO2 CTCs due to their role as recombination centers.

Summary: The impact of oxygen concentration on the structural, optical properties, and device performance of Ga2O3 thin film was investigated by controlling the oxygen flow rate during deposition. Higher oxygen flow rate led to poorer crystalline quality, increased film roughness, and introduction of defects. Decreasing oxygen concentration resulted in an increase in optical bandgap, a decrease in blue band contribution, and reduced defect concentration, surface roughness, and interface states. These findings are significant for improving the quality of Ga2O3 films and their applications in device fabrication.

Summary: In this study, a series of NixZn1-xFe2O4 catalysts with different oxygen vacancy content were prepared by adjusting the doping content of Ni and used for activating peroxymonosulfate (PMS) to degrade tetracycline (TC). The results showed that Ni0.6Zn0.4Fe2O4 with the highest oxygen vacancy content exhibited the highest TC removal efficiency and the maximum degradation rate constant in the Ni0.6Zn0.4Fe2O4/PMS system. The role of oxygen vacancy on the Ni0.6Zn0.4Fe2O4 surface was investigated and it was found that the adsorption and capture of PMS, as well as the generation of reactive oxygen species, were promoted by the oxygen vacancy. In addition, TC could be oxidized by directly donating electrons to the metastable complex formed by the reaction between Ni0.6Zn0.4Fe2O4 and PMS.

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.
