Summary: In this study, the growth kinetic process, morphology, and stability of Au@Cu2O nanostructures were controlled by employing different surface ligands. The use of CTAB resulted in relatively stable cubic nanostructures, while the use of SDS led to the formation of nanocubes that were unstable and prone to detachment. On the other hand, the use of PAA produced the most stable nanostructures with rough surfaces. This study provides an effective way to control the nanostructures and stability of metal-semiconductor heterostructures.

Summary: Ni/Ni3C core-shell nanoparticles with an average diameter of approximately 120 nm were synthesized via a chemical solution method. It was observed that a thin Ni3C shell measuring approximately 1-4 nm formed on the surface of the nanoparticles over time, and the Ni core consisted of multiple grains. The saturation magnetization of the core-shell nanopowders decreased in proportion to the amount of Ni3C. The synthesis mechanism of the Ni/Ni3C core-shell nanoparticles was proposed based on XRD, XPS, and TEM analyses.

Summary: The dielectric properties of PVDF-g-BT core-shell structured nanocomposites obtained by RAFT polymerization were investigated. The dielectric constant increased with the addition of BT, exhibiting a larger increase than predicted by usual modeling methods for composite materials, due to the effect of the interfacial core-shell structure. PVDF's known dielectric relaxations were observed in both the neat polymer and its nanocomposites, unaffected by the presence of nanoparticles. A relaxation process due to interfacial polarization was found at higher temperatures, attributed to the high crystallinity of the materials produced by RAFT.

Summary: Magnetic core-shell composites of Fe3O4 nanoparticles encapsulated with NHC-M (M = Ir, Pd) coordination assemblies act as solid molecular catalysts with enhanced catalytic activity in CO2 hydrogenation and dehydrogenation reactions. The hydrogenation of CO2 to formic acid achieved a record turnover number (TON: 1.69 x 106). The robust solid catalysts can be magnetically recovered and reused for more than 11 runs without significant loss in activity and selectivity, even at a catalyst loading level of 10-6 mmol.
