The core-shell structured microcapsular-like Ru@SiO(2) reactor is proved to be the most efficient material known to date for CO(x)-free hydrogen production via ammonia decomposition for fuel cells application. The very active Ru core particles can retain good stability even at high temperatures (up to 650 degrees C) thanks to the protection of the inert SiO(2) nano-shell.

Lanthanide-doped fluoride nanoparticles show great potential for optical thermometry and bioimaging. However, their applications are still constrained by inherent limitations in luminescence intensity and functional versatility. To overcome these challenges, we propose a core-active shell-inert shell nanostructure that integrates multifunctional capabilities within a single platform.

The efficient and sustainable remediation of contaminated water calls for catalytic systems that must clean broadly, endure widely, and last repeatedly. In this regard, we report the development of sulfonate-functionalized core-shell hydrogel beads embedded with synthesized gold nanoparticles (AuNPs) that exhibit intrinsic oxidase-like activity without requiring external light or chemical oxidants. The sulfonate ligands modulate the surface electronic environment of the AuNPs, facilitating singlet oxygen generation via a nonplasmonic, radiationless mechanism.

Precisely structured nanoclusters provide ideal platforms for elucidating structural evolution and structure-activity relationships. However, mechanistic understanding of dynamic core-shell rearrangements has long been impeded by the elusive nature of intermediates during transformation processes. Here, we show that ligand engineering-driven asymmetric thiolate exchange enables atomic-level visualization of structural evolution, thereby overcoming the long-standing challenge of intermediate capture.

Pd-zeolites are promising passive NO adsorber (PNA) materials for mitigating cold-start emissions from lean-burn engines. However, their practical deployment is constrained by insufficient densities and dispersion of isolated Pd active sites as well as their susceptibility to hydrothermal degradation and phosphorus poisoning encountered in vehicle exhaust environments. Herein, we develop a rationally engineered core-shell Pd/SSZ-13@AlO composite, featuring a Pd/SSZ-13 core encapsulated within a mesoporous AlO shell.

Here, Ln-Li co-doped YO@ZnO core-shell heterostructures were synthesized by three different techniques - intermediate layer conversion method, a hydrothermal method, and an interlayer mediated hydrothermal method. The synthesis procedure is optimized based on the thickness and compactness of the developed shell. The growth kinetics and synthesis mechanism of each adopted method have been explained in detail using XRD, FESEM, TEM, SAED, and EDX characterization techniques.
