Preparation and Photocatalytic Degradation Performance of C@CdMnS to Tetracycline Hydrochloride.

CdMnS solid solutions were synthesized by incorporating Mn into CdS and the optimal ratio of Mn to Cd was explored via photocatalytic degradation performance for tetracycline (TC). Subsequently, the composite catalyst C@CdMnS was prepared by loading CdMnS onto the biomass gasification carbon residue (C) by hydrothermal method and characterized by various characterization tests. The optimal TC photodegradation condition and degradation mechanism catalyzed by C@CdMnS was investigated.

Fast-moving soft electronic fish.

Soft robots driven by stimuli-responsive materials have unique advantages over conventional rigid robots, especially in their high adaptability for field exploration and seamless interaction with humans. The grand challenge lies in achieving self-powered soft robots with high mobility, environmental tolerance, and long endurance. We are able to advance a soft electronic fish with a fully integrated onboard system for power and remote control.
