Thermal Conductivity of Solid Triphenyl Phosphite

open access: yesMolecules, 2022
The thermal conductivity, κ, of solid triphenyl phosphite was measured by using the transient hot-wire method, and its temperature and pressure dependencies were analyzed to understand heat transfer processes in the solid polymorphic phases, as well as in the glass and the exotic glacial state.

Direct observation of one-dimensional disordered diffusion channel in a chain-like thermoelectric with ultralow thermal conductivity

open access: yesNature Communications, 2021
Disordered, diffusive atoms are rarely found in simple crystalline solids. Here, the authors observe one-dimensional disordered diffusion channel in a simple chain-like thermoelectric InTe with ultralow thermal conductivity.
