Lightweight and drift-free magnetically actuated millirobots via asymmetric laser-induced graphene

Nature Communications
Millirobots must have low cost, efficient locomotion, and the ability to track target trajectories precisely if they are to be widely deployed. With current materials and fabrication methods, achieving all of these features in one millirobot remains ...

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

Advanced Materials Interfaces, EarlyView.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

Interfacial Electronic Restructuring in MAPbBr3/rGO Hybrids Enabling Improved Charge Extraction for Efficient Photodetection

Advanced Materials Interfaces, EarlyView.
MAPbBr3/rGO hybrids exhibit interfacial electronic restructuring that enhances charge extraction in photodetectors. The incorporation of rGO modifies the surface chemical environment, enhances electron‐dominated transport, and suppresses performance degradation, resulting in higher responsivity, detectivity, and photostability than in pristine MAPbBr3 ...
