Summary: This study reports a mesoporous silica-based ternary flame retardant (NF@SiO2-D) for unsaturated polyester (UP) by loading nickel ferrite and dimethyl methylphosphonate (DMMP) via hierarchical assembly. NF@SiO2-D acts as a fire extinguisher of UP through the combined effect of mesoporous silica, nickel ferrite, and DMMP. The UP matrix with NF@SiO2-D exhibited reduced heat release rates and smoke production, achieved a self-extinguishing ability, and demonstrated improved thermal stability and Tg compared to the control samples. The flame-retardant UP composites are expected to have more industrial applications.

Summary: The study found that the presence of trace water vapor can significantly increase the CO2 adsorption capacity and capture rate of PILs-functionalized SBA-15, attributed to the additional CO2 capture pathway formed. Additionally, the hybrid sorbents showed strong resistance to SO2 and NO, with limited impact on CO2 capture, and the CO2 adsorption capacities remained stable after multiple cyclic adsorption/regeneration experiments.

Summary: This study investigated CO2 adsorption over functionalized mesoporous silica and found that hydrogen bonding interactions with surface silanols and neighboring amines were critical for the formation and stabilization of the adsorption products. It was also shown that surface silanols played a significant role in the thermodynamics and kinetics of the reaction mechanism, and could directly participate in the reaction. The impact of amine functionality on the reaction mechanism was found to be less conclusive compared to surface silanols under the conditions employed in this study.

Summary: In this study, a highly efficient nanocarrier for delivering siRNA into cancer cells was developed. The nanocarrier, made of fluorescent mesoporous silica nanoparticles with a polyethylenimine coating, showed good biocompatibility and negligible toxicity. By protecting siRNA from degradation, the nanocarrier successfully delivered siRNA into 293T cells and inhibited the expression of related genes. This study provides insights into the development of nonviral fluorescence nanocarriers for siRNA delivery, which is important for targeted cancer therapy.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
