Northwestern University scientists have developed a thermoelectric material that is the best in the world at converting waste heat to electricity. This is very good news once you realize nearly two-thirds of energy input is lost as waste heat. The material could signify a paradigm shift. The inefficiency of current thermoelectric materials has limited their commercial use. Now, with a very environmentally stable material that is expected to convert 15 to 20 percent of waste heat to useful...

New material finds 'needle in a haystack,' shows promise for clean-up Not every object is food to a Venus flytrap. Like the carnivorous plant, a new material developed at Northwestern University permanently traps only its desired prey, the radioactive ion cesium, and not other harmless ions like sodium. The synthetic material, made from layers of a gallium, sulfur and antimony compound, is very selective. The Northwestern researchers found it to be extremely successful in removing cesium --...

With gasoline at high prices, it's disheartening to know that up to three-quarters of the potential energy you are paying for is wasted. A good deal of it goes right out the tailpipe instead of powering your car. Now a Northwestern University-led research team has identified a promising new material that could transform a technology that currently cools and heats car seats -- thermoelectrics -- into one that also efficiently converts waste heat into electricity to help power the car and...
