Achieving Ultralow Lattice Thermal Conductivity and High Thermoelectric Performance in GeTe Alloys via Introducing Cu2Te Nanocrystals and Resonant Level Doping.

ACS Nano, 2021
The binary compound of GeTe emerging as a potential medium-temperature thermoelectric material has drawn a great deal of attention. Here, we achieve ultralow lattice thermal conductivity and high thermoelectric performance in In and a heavy content of Cu

The thermal conductivity coefficient of polyatomic molecules: benzene

Fluid Phase Equilibria, 1992
Abstract The thermal conductivity of a rigid benzene-like model fluid is evaluated using the nonequilibrium molecular dynamics algorithm of Evans, and Evans and Murad. The contribution to the conductivity from rotational degrees of freedom is shown to be significant and density dependent. These contributions are contrasted with those of a homonuclear

Thermal conductivity and heat transfer coefficient of concrete

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2011
A very simple model for predicting thermal conductivity based on its definiensis was presented. The thermal conductivity obtained using the model provided a good coincidence to the investigations performed by other authors. The heat transfer coefficient was determined by inverse analysis using the temperature measurements. From experimental results, it

Synchronously improved electromagnetic interference shielding and thermal conductivity for epoxy nanocomposites by constructing 3D copper nanowires/thermally annealed graphene aerogel framework

, 2020
3D copper nanowires-thermally annealed graphene aerogel (CuNWs-TAGA) framework is firstly prepared by freeze-drying followed by thermal annealing from CuNWs, graphene oxide (GO) and L-ascorbic acid. Epoxy resin is then poured back into the above 3D CuNWs-

Coefficients of Diffusion, Viscosity, and Thermal Conductivity of a Gas

American Journal of Physics, 1962
The coefficients of diffusion, viscosity, and thermal conductivity of a gas are derived in first approximation following the method of Maxwell and Chapman. The derivation differs from previous derivations primarily in the expression and evaluation of the various collision integrals.
