Summary: Pd-ZnO nanocomposite was synthesized via solvothermal method, and then PdO-ZnO was obtained through calcination. XRD, TEM, and XPS tests confirmed the conversion of Pd to PdO during calcination. Photocatalytic sterilization experiments showed that PdO-ZnO exhibited faster and more effective killing of E. coli compared to Pd-ZnO. ESR tests indicated the presence of & BULL;OH and & BULL;O2- signals in PdO-ZnO under light. Scanning electron microscopy demonstrated that PdO-ZnO disrupted the bacterial membrane structure to inactivate E. coli. Cytotoxicity experiments on HTT2 confirmed the non-toxic nature of PdO-ZnO.

Summary: Ag/Au/Fe3O4/graphene composites prepared by a hydrothermal method exhibited excellent activation of H2O2 and were effective in degrading methylene blue (MB) in solution under light and ultrasound irradiation, in the presence of organic acids and inorganic ions. The composites showed excellent magnetic properties, crystallinity, and stability. The results revealed a synergistic interaction between Ag, Au, and Fe3O4/graphene/H2O2 systems, leading to enhanced removal efficiency of MB. Organic acids accelerated degradation, while most anions inhibited MB degradation, with CO32- having the highest inhibition effect. Cations such as Na+, K+, Ca2+, and Mg2+ also suppressed MB degradation, likely due to the presence of Cl- in the solutions.

Summary: This study investigates the corrosion mechanism of CA(6) based refractory by refining slag. The results show that CaAl4O7 plays a crucial role in the slag corrosion resistance of the refractories. The CA(6) refractory exhibits the most excellent slag corrosion due to the rapid collapse of its double pyramid module and the formation of a dense CaAl4O7 reaction layer. On the other hand, the Al2O3 refractory shows the worst slag corrosion due to the slower and smaller generation of CaAl4O7.

Summary: In this study, the Rb1-xCsx[Ce(Ta1-xNbx)2O7] layered perovskite with Nb substitutions was prepared and investigated. It was found that the color of the solid solutions changed from pale-green to dark reddish-brown with increasing amount of substituted niobium. This unique coloring state change behavior was not observed in other analogues. First-principles calculations indicated that the band structural change is the key factor for the coloration modulation.

Summary: Ternary metal oxides (TMOs) with flexible band structures have great potential in photocatalysis. Introduction of N atoms into TMOs can enhance their visible light absorption capacity and improve photocatalytic performance. This review summarizes recent research on N-modified TMOs, including the influence of N doping amounts, N doping sites, and N-induced phase transformation. The optimal N concentration and the influence of N doping sites are investigated. The introduced N can tune the vacancies in TMOs, which is vital for inducing different activity and selectivity. The topochemical ammonolysis process can convert TMOs to oxynitride with enhanced photocatalytic activity.

Summary: This study investigates the multiscale behaviors of sapphire crystal growth along different crystal directions through theoretical and experimental studies. The results show that the growth behavior of sapphire along the c-axis is more complex compared to that along the a- and m-axes, involving solid-liquid and solid-solid transformations. Moreover, an abrupt change in the interfacial structure inhibits the transformation of liquid Al2O3 into α-Al2O3 along the c-axis.

Summary: Investigating the liquid structure of yttrium aluminum garnet (YAG) at high temperatures is significant for various fields, and molecular dynamic simulations were used to study the structure of YAG within a certain temperature range and to grow a YAG single crystal. The coordination number and bond length between cations and anions changed after melting, which can be explained by Pauling's third rule. In the liquid YAG, the coordination number decreased and the main structural units were AlO4 and YO7, which provided insight into phase selection and enabled rapid growth of YAG using the Czochralski method.

Summary: The functionality of inorganic materials depends on their chemical composition, morphology, particle size, and crystal facet, which are influenced by the synthesis process. Precise control of the synthesis process can lead to the discovery of new functionality and improvement of materials. Solution processes allow for precise control of morphology and particle size, and are strongly related to the dissolution reprecipitation mechanism, enabling strict control of material composition and formation of highly crystalline particles. This review focuses on the role of solvents in the solution process, their effect on particle size and morphology of transition metal oxides, related functional improvements, direct formation of functional thin films, and morphology control by non-oxide materials through topotactic reactions.
