Thermal conductivity terms Links

Thermal Properties of Metallic Solids. In the preceding sections, we saw that thermal conductivities of gases, and to some extent liquids, could be related to viscosity and heat capacity. For a solid material such as an elemental metal, the link between thermal conductivity and viscosity loses its validity, since we do not normally think in terms of solid viscosities. The connection with heat capacity is still there, however. In fact, a theoretical description of thermal conductivity in solids is derived directly from the kinetic gas theory used to develop expressions in Section 4.2.1.2. 

In a series of reports from the Dhirani group, " a metal-insulator transition was found to occur for Au MPC dithiol-linked films of n>5. They investigated the metal-insulator transition in terms of percolation effects. Films below a certain thickness threshold exhibit thermally activated electronic conductivity and conductance suppression near zero bias, a consequence of a possible Coulomb... 

The slow crystallization of the PEO/LiX complex results in a decrease in ionic conductivity with storage time. To maintain the long-term stability of ionic conductivity, the mixture of PEO and a large poly(oxyethylene-vinyl styrene) oligomer and nitrile rubber is directly cross-linked by thermal polymerization, resulting in greatly improved stability of the ionic conductivity.
