Researchers at Boston College and MIT have used nanotechnology to achieve a major increase in thermoelectric efficiency, a milestone that paves the way for a new generation of products - from semiconductors and air conditioners to car exhaust systems and solar power technology - that run cleaner.
The team's low-cost approach, details of which are published today in the online version of the journal Science, involves building tiny alloy nanostructures that can serve as micro-coolers. (source: web.mit.edu)
