New Technique Increases Nanofiber Production Rate Fourfold

Scientists from MIT have demonstrated a systematic way to produce nanofibers through electrospinning that boosts production 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 […]

Safe Drinking Water Via Solar Power Desalination

Natasha Wright, an MIT PhD student in mechanical engineering, has designed a solar powered system that makes water safe to drink for rural, off-grid Indian villages. When graduate student Natasha Wright began her PhD program in mechanical engineering, she had no idea how to remove salt from groundwater to make it more palatable, nor had she ever […]

Engineers Develop Micro-tentacles So Tiny Robots Can Handle Delicate Objects

Engineers at Iowa State University developed spiraling microrobotic tentacles that can gently grip delicate objects. The tiny tube circled an ant’s thorax, gently trapping the insect and demonstrating the utility of a microrobotic tentacle developed by Iowa State University engineers. “Most robots use two fingers and to pick things up they have to squeeze,” said […]

Rapid Fabrication of Nanoscale Geometric Grids Using Lasers

Rapid creation of multi-layered, self-assembled nanoscale grids with fully customizable shapes and compositions is possible using new technique developed by scientists at Brookhaven Lab. Down at the nanoscale, where objects span just billionths of a meter, the size and shape of a material can often have surprising and powerful electronic and optical effects. Building larger […]
