Unlocking nanofibers' potential
Boston MA (SPX) Jun 15, 2015
Nanofibers - polymer filaments only a couple of hundred nanometers in diameter - have a huge range of potential applications, from solar cells to water filtration to fuel cells. But so far, their high cost of manufacture has relegated them to just a few niche industries. In the latest issue of the journal Nanotechnology, MIT researchers describe a new technique for producing nanofibers that increases the rate of production fourfold while reducing energy consumption by more than 90 percent, holding ... read more
