Blacksmiths fire metals before hammering them, as heat always softens metal, making it more malleable and easier to reshape. Or does it? In a surprising new study, engineers from Northwestern University (Evanston, Ill.) discovered that, in extreme conditions, heat does not soften pure metals—it strengthens them.
Stacking up: A new take on diamond electronics
Researchers at the U.S. Department of Energy’s Argonne National Laboratory have overcome a critical barrier in diamond-based electronics and microelectronics by using nanotechnology to integrate two-dimensional materials for efficient n-type doping, a breakthrough in electronic materials designed to operate in high-temperature environments and other harsh environments.
