An international team of scientists has found the thermal conductivity of graphene changes depending on the size of the material sample, a discovery they say challenges the fundamental laws of heat conduction for extended materials. Davide Donadio, head of a research group at the Max Planck Institute for Polymer Research (MPI-P) in Germany and his colleagues from the National … [Read more...]

Solving the Thermoelectric Mystery
Thermoelectric materials—substances that exhibit the so-called thermoelectric effect, in which a temperature difference creates an electric potential or vice versa—have been known for decades and employed in applications including power generation and refrigeration. Despite their commercial use, however, scientists have remained somewhat baffled as to why some of these … [Read more...]
