Addressing the real problem: Through muscle regeneration, graphene-polymer matrix lowers risk of rotator cuff retear injuries

By Lisa McDonald / August 23, 2022

Most rotator cuff repair procedures focus on the tendon, but the real problem is that the muscle degenerates and accumulates fat. University of Connecticut School of Medicine researchers led by ACerS Fellow Cato Laurencin developed a graphene-polymer matrix that induces a reversal of muscle degeneration, thereby greatly lowering the risk of rotator cuff retear injuries.

A sweet demonstration: Ceria helps make miniaturized implantable glucose fuel cells possible

By Lisa McDonald / June 10, 2022

Glucose fuel cells allow for significant volumetric scale-down of implantable devices because they do not physically store energy like batteries. However, cells that use polymer-based electrolytes face some limitations. Researchers from MIT and the Technical University of Munich developed glucose fuel cells using a ceramic membrane that overcome these limitations.
