Fast-moving electrons create current in organic solar cells

Researchers at Purdue University have identified the mechanism that allows organic solar cells to create a charge, solving a longstanding puzzle in physics, according to a paper published Friday (Jan. 12) in the journal Science ...

Stingray-inspired soft biobot

UCLA bioengineering professor Ali Khademhosseini has led the development of a tissue-based soft robot that mimics the biomechanics of a stingray. The new technology could lead to advances in bio-inspired robotics, regenerative ...

Nanostructure boosts stability of organic thin-film transistors

A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate ...

Q&A: What Facebook's shift could mean to users, businesses

In coming days, Facebook users will see fewer posts from publishers, businesses and celebs they follow. Instead, Facebook wants people to see more stuff from friends, family and other people they are likely to have "meaningful" ...
