Understanding how thin-film coatings react to temperature changes could lead to more effective and durable sensors, solar-energy converters, safer medical implants and a host of other applications, says Jodie Lutkenhaus, assistant professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, who has found that heating some of these films can increase their stability.

The findings, which appear in an upcoming issue of Soft Matter, a scientific journal published by the Royal Society of Chemistry, represent a significant step forward in the study of multilayer polymer thin-film coatings — material gaining increased interest for its potential versatility in a number of applications ranging from biomedical to industrial.

Via KurzweilAI.net — This may prove to be a major medical breakthrough once some practical applications get into actual practice and spur on additional innovation.

Biodegradable Transistors
Technology Review, Nov. 13, 2009

Fully biodegradable organic transistors have been fabricated by researchers at Stanford University.

They could be used to control temporary medical implants placed in the body during surgery, and help monitor the healing process from inside the body.
