Summary: We report on the fabrication of three-dimensional hierarchical core-satellite SiO2@monomicelle spherical superstructures through a previously unexplored monomicelle interfacial super-assembly route. The ultrathin single layer of monomicelle subunits with hexagon-like regular discontinuous distribution on solid spherical interfaces can be achieved, and the number of monomicelles on colloidal SiO2 interfaces can be quantitatively controlled. This strategy provides a controllable way for building multiscale hierarchical regular micro- and/or macroscale materials and devices.

Summary: In this study, a metal-ligand cross-linking strategy was developed for the fabrication of ferric ion-dopamine coordination hierarchical superstructures. Various superstructures with complex morphologies were synthesized, and the formation mechanism was explored. The hierarchical superstructure was used as peroxidase-like ligase mimics to enhance tumor photothermal treatment, and it showed effective tumor cell ablation in vitro and in vivo. This work opens new horizons in hierarchical superstructures and has great potential in nanozymology, biomedical science, and catalysis.

Summary: DNA has long been used as a template for constructing helical assemblies of inorganic nanoparticles, but achieving helices without biological ligands is challenging. Atomically precise nanoclusters protected by ligands demonstrate hierarchical structural complexity, similar to biomolecules. The newly synthesized homodimeric and heterodimeric gold nanoclusters self-assemble into superstructures, with heterodimeric clusters forming more complex helical superstructures driven by van der Waals interactions. The surrounding ligands on the clusters contribute to the assembly through paired steric interactions.

Summary: The study reported the synthesis and catalytic activity of two ephedrine-based catalysts and two ephedrine-based magnetic nanoparticle-supported catalysts in the addition of diethylzinc to aromatic aldehydes and in the Henry reaction. The nanocatalyst showed poor performance in the addition of diethylzinc to aldehydes, but gave reasonable results in the Henry reaction. The proposed system is the first recyclable ephedrine-based magnetic nanocatalyst employed in an enantioselective reaction.
