R&D Mag – The intense interest in harvesting energy from heat sources has led to a renewed push to discover materials that can more efficiently convert heat into electricity. Some researchers are finding those gains by re-designing materials scientists have been working with for years.
A team of Boston College and Massachusetts Institute of Technology researchers report developing a novel, nanotech design that boosts the thermoelectric performance of a bulk alloy semiconductor (silicon germanium) by 30 to 40% above its previously achieved figure. more> http://is.gd/oJOSUE
