Nitrogen-Doped Mesoporous Carbon-Encapsulated MoO Nanobelts as a High-Capacity and Stable Host for Lithium-Ion Storage.

N-doped mesoporous carbon-capped MoO nanobelts (designated as MoO @NC) were synthesized and applied to lithium-ion storage. Owing to the stable core-shell structural framework and conductive mesoporous carbon matrix, the as-prepared MoO @NC shows a high specific capacity of around 700 mA h g at a current of 0.5 A g , excellent cycling stability up to 100 cycles, and superior rate performance.

Synthesis of Yolk-Shell Structured Fe3O4@void@CdS Nanoparticles: A General and Effective Structure Design for Photo-Fenton Reaction.

Yolk-shell (Y-S) structured Fe3O4@void@CdS nanoparticles (NPs) are synthesized through a one-pot coating-etching process with Fe3O4@SiO2 as the core, where the coating of an outer CdS shell from a chemical bath deposition (CBD) process is simultaneously accompanied by the gradual etching of an inner SiO2 shell. The as-prepared Fe3O4@void@CdS NPs (ca. 200 nm) possess good monodispersity and a uniform CdS shell of ca.

Dual-Shell Fluorescent Nanoparticles for Self-Monitoring of pH-Responsive Molecule-Releasing in a Visualized Way.

The rational design and controlled synthesis of a smart device with flexibly tailored response ability is all along desirable for bioapplication but long remains a considerable challenge. Here, a pH-stimulated valve system with a visualized "on-off" mode is constructed through a dual-shell fluorescence resonance energy transfer (FRET) strategy. The dual shells refer to carbon dots and fluorescent molecules embedded polymethacrylic acid (F-PMAA) layers successively coating around a SiO2 core (ca.

Stöber strategy for synthesizing multifluorescent organosilica nanocrystals.

The Stöber process is revisited using vinyltriethoxysilane as the precursor, where a kinetics-controlled condensation of vinylsilanols, free from external fluorogens, unprecedentedly produces hydrophilic diamond-structured organosilica nanocrystals (ca. 2-6 nm) with finely tunable fluorescence (460-625 nm). The key to the synthesis lies in a slow successful condensation of vinylsilanols triggered and guided by the π-π stacking interaction of vinyl groups.
