PITTSBURGH — University of Pittsburgh researchers have created a nanoscale light sensor that can be combined with near-atomic-size electronic circuitry to produce hybrid optic and electronic devices with new functionality. The team, which also invo…
OAK RIDGE, Tenn., Sept. 14, 2010 — As industries and consumers increasingly seek improved battery power sources, cutting-edge microscopy performed at the Department of Energy’s Oak Ridge National Laboratory is providing an unprecedented perspective…
Specific heat theories of Debye’s phonons and Einstein’s atomic vibrations including modification thereof by Raman are modified by quantum mechanics to include zero specific heat at the nanoscale.
University of Minnesota researchers have made the first-ever hardness measurements on individual silicon nanospheres and shown that the nanospheres’ hardness falls between the conventional hardness of sapphire and diamond, which are among the hardest known materials. Being able to measure such nanoparticle properties may eventually help scientists design low-cost superhard materials from these nanoscale building blocks. Up to four times harder than typical silicon — a principal ingredient of computer chips, glass and sand — the nanospheres demonstrate that other materials at the nanoscale, including sapphire, may also have vastly improved mechanical properties.
