MIT News: Unlocking nanofibers’ potential – Prototype boosts production of versatile fibers fourfold, while cutting energy consumption by 92 percent
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
