Edge‐Delocalized Electron Effect on Self‐Expediating Desolvation Kinetics for Low‐Temperature Li─S Batteries

Advanced Functional Materials, EarlyView.
The self‐transformed Schottky heterojunction on MXene is developed to facilitate the dissociation of Li (solvent)x+ to achieve fast Li+ desolvation to promote rapid sulfur conversion kinetics by decreasing the related barriers, contributing to high‐performance Li─S batteries under low‐temperatures.

Acoustically propelled nanoshells

Nanoscale, 2016
Herein we report a new design for acoustic nanoswimmers, making use of a nanoshell geometry that was synthesized using a sphere template process. Such shell-shaped nanomotors display highly efficient acoustic propulsion on the nanoscale by converting energy from the ambient acoustic field into motion.

Microbubble‐Controlled Delivery of Biofilm‐Targeting Nanoparticles to Treat MRSA Infection

Advanced Functional Materials, EarlyView.
Here, an effective strategy using microbubble (MB)‐controlled delivery of biofilm‐targeting nanoparticles (BTNs) for removal and therapy of methicillin‐resistant Staphylococcus aureus (MRSA) biofilm infections is introduced. In vivo delivery of MB with BTN is demonstrated to silence key bacterial genes involved in biofilm formation (icaA), bacterial ...
