Modern electronics as we know them, from televisions to computers, depend on conducting materials that can control electronic properties. As technology shrinks down to pocket sized communications devices and microchips that can fit on the head of a pin, nano-sized conducting (more…)

U.S. researchers say they have created a material that can generate electricity from waste heat with greater efficiency than other technologies. Scientists at Northwestern University placed nanocrystals of rock salt into lead telluride to create a material with the potential to capture waste heat from factory equipment, vehicle exhaust, and other industrial (more…)
