(Phys.org)—A team of researchers with George Fox University in Oregon and the University of Montana has uncovered the ways in which calliope hummingbirds (Selasphorus calliope) get rid of the large amount of heat that is ...
EPFL researchers have shed new light on the fundamental mechanisms of heat dissipation in graphene and other two-dimensional materials. They have shown that heat can propagate as a wave over very long distances. This is key ...
