Examining the flow of thermal energy in purified ribbons of graphite

Scientists from the Institute of Industrial Science at The University of Tokyo studied the flow of thermal energy in purified ribbons of graphite and showed that heat can move more like a liquid, rather than diffusing randomly, ...
