Study: Electric fields boosted heat flow by nearly 300%
Scientists at Oak Ridge National Laboratory have found that applying an electric field to a specialized ceramic can nearly ...
In most conventional semiconductors, thermal conductivity decreases as temperature rises because heat-carrying lattice vibrations—called phonons—scatter more frequently.
The quantum of thermal conductance, G Q = πk B 2 T/6ℏ, provides the fundamental upper limit for heat conduction through a single channel 8,9. Here, T is the temperature, k B denotes the Boltzmann ...
Combining state-of-the-art realistic atomistic modelling and experiments, the paper describes how thermal conductivity of ultrathin silicon membranes is controlled to large extent by the structure and ...
After a decade of work, Issam Mudawar will soon see the results of the largest phase change experiment ever conducted in space. WEST LAFAYETTE, Ind. — People who design spacecraft must prioritize two ...
The particles of liquids are further apart than solids. This means that most liquids are poor conductors of heat because the frequency of collisions is reduced. The particles of gases are even further ...
