New studies explain insulator-to-metal transition of vanadium dioxide
When heated to just above room temperature, the electrical conductivity of vanadium dioxide (VO2) abruptly increases by a factor of 10,000. Experiments coupled with high-performance computation reveal how ...
Clean interfaces: Research could usher in next generation of batteries, fuel cells
Scientists from South Carolina's leading public universities—the University of South Carolina and Clemson University—have made a discovery that could dramatically improve the efficiency of batteries and fuel cells.
Small electric voltage alters conductivity in key materials
Modern research has found no simple, inexpensive way to alter a material's thermal conductivity at room temperature.
Researchers discover N-type polymer for fast organic battery
Researchers at the University of Houston have reported developing an efficient conductive electron-transporting polymer, a long-missing puzzle piece that will allow ultrafast battery applications.
Huge reduction of heat conduction observed in flat silicon channels
Combining state-of-the-art realistic atomistic modelling and experiments, a new paper describes how thermal conductivity of an ultrathin silicon membrane is controlled to a large extent by the structure and ...
'Microcombing' creates stronger, more conductive carbon nanotube films
Researchers from North Carolina State University and China's Suzhou Institute of Nano-Science and Nano-Biotics have developed an inexpensive technique called "microcombing" to align carbon nanotubes (CNTs), ...
