Summary: A method for fabricating TiO2-supported nano-Au and Ag catalysts with enhanced activity in nitroarenes reduction was presented by immobilizing metal NPs onto TiO2 through metal precursors adsorption and in situ metal cations reduction. The type of reducing agent used influenced the size, oxidation state, and loading of the grafted metal NPs, resulting in Au and Ag nanocomposites with different characteristics and catalytic performances in the reduction of 4-nitrophenol and 4-nitroaniline. Au/Ag-based nanocomposites prepared with NaBH4 and citric acid showed efficient catalytic activity with high substrate conversion rates under mild conditions.

Summary: A catalytic membrane nanoreactor (CMNR) with Cu-Ag bimetallic catalysts immobilized in membrane pores was successfully fabricated via flowing synthesis and replacement reaction. The Cu core acts as an electron-deficient site to activate the -NO2 group for p-NP, while the Ag shell enhances active H spilling to the Cu surface for hydrogenation. The highest reaction rate constant of 1071 min(-1) was achieved for CMNR immobilized with Cu-Ag-2 due to suitable adsorption activation behavior and best hydrogen spillover behavior.

Summary: In this study, hydrophilic-to-amphiphilic alkylated N-vinylimidazolium based ionic liquid monomers with various counter anions were incorporated into N-vinylcaprolactam (VCL) based microgels via precipitation polymerization, and their properties were investigated. Two strategies, pre-functionalization and post-functionalization, were applied and compared. Different counterions and alkyl chain lengths affected the size, swelling behavior, and electrophoretic mobility of the resulting microgels. The pre-functionalization approach allowed for the formation of anisotropic microgels with restricted swelling. The results of this study have implications for the controlled design of functional microgels for various applications.

Summary: In this study, a photothermal-responsive yolk-shell nanoreactor with tunable location of metal nanoparticles (NPs) was developed. The catalytic performance of these nanoreactors can be controlled by both light irradiation and conventional heating. The location of the catalysts had a significant impact on the reduction kinetics of the nanoreactors, with catalysts in the shell exhibiting higher catalytic activity compared to those in the core under conventional heating. When subjected to light irradiation, nanoreactors with catalysts loaded in the core demonstrated improved catalytic performance compared to direct heating, while nanoreactors with catalysts in the shell exhibited relatively similar activity. The enhancement in catalytic activity was attributed to the spatial distribution of the catalysts and the localized heating within the polydopamine cores of the nanoreactors.

Summary: In this study, pH-responsive drug carriers were successfully fabricated and it was demonstrated that the distribution of charges has an impact on delivery efficiency. By synthesizing polyampholyte nanogel-in-microgel colloids, the arrangement of nanogels could be easily manipulated by adjusting synthesis conditions.

Confocal laser scanning microscopy confirmed the formation of colloids with different nanogel arrangements depending on nanogel concentration, pH value, and ionic strength. This research is a significant advancement in the uptake and release of oppositely charged drug molecules.
