Thermal conductivity of Triassic evaporites

open access: yesGeophysical Journal International, 2021
SUMMARY Evaporites occur in various geological environments: sedimentary basins, orogenic belts, where they often act as tectonic decoupling layers, and as top-seals in hydrocarbon fields. In all cases, they affect the temperature distribution in the upper crust, as their thermal conductivity is relatively higher with respect to other ...

A Universal Gauge for Thermal Conductivity of Silicon Nanowires With Different Cross Sectional Geometries

open access: yes, 2011
By using molecular dynamics simulations, we study thermal conductivity of silicon nanowires (SiNWs) with different cross sectional geometries. It is found that thermal conductivity decreases monotonically with the increase of surface-to-volume ratio (SVR)

Light beam dynamics in materials with radially-inhomogeneous thermal conductivity

open access: yes, 2013
We study the properties of bright and vortex solitons in thermal media with nonuniform thermal conductivity and homogeneous refractive index, whereby the local modulation of the thermal conductivity strongly affects the entire refractive index ...

High thermal conductivity in cubic boron arsenide crystals

open access: yesScience, 2018
Moving the heat aside with BAs Thermal management becomes increasingly important as we decrease device size and increase computing power. Engineering materials with high thermal conductivity, such as boron arsenide (BAs), is hard because it is essential ...

Experimental Determination of the Lorenz Number in Cu0.01Bi2Te2.7Se0.3 and Bi0.88Sb0.12

open access: yes, 2012
Nanostructuring has been shown to be an effective approach to reduce the lattice thermal conductivity and improve the thermoelectric figure of merit. Because the experimentally measured thermal conductivity includes contributions from both carriers and ...

Thermal conductivity of antigorite

open access: yes, 2023
This repository contains experimental data on the thermal conductivity of antigorite at high pressures and temperatures as well as a self-written MATLAB script used to numerically model 2D thermal evolution of a sinking slab. These materials are presented in a manuscript submitted by Yu-Hsiang Chien, Enrico Marzotto, Yi-Chi Tsao, and Wen-Pin Hsieh ...

Impact of Screw and Edge Dislocation on the Thermal Conductivity of Nanowires and Bulk GaN

open access: yes, 2017
We report on thermal transport properties of wurtzite GaN in the presence of dislocations, by using molecular dynamics simulations. A variety of isolated dislocations in a nanowire configuration were analyzed and found to reduce considerably the thermal ...

Machine-learning-assisted discovery of polymers with high thermal conductivity using a molecular design algorithm

open access: yesnpj Computational Materials, 2019
The use of machine learning in computational molecular design has great potential to accelerate the discovery of innovative materials. However, its practical benefits still remain unproven in real-world applications, particularly in polymer science.

Phonon transport in $\mathrm{Na_2He}$ at high pressure from a first-principles study

open access: yes, 2017
Phonon transport of recently-fabricated $\mathrm{Na_2He}$ at high pressure is investigated from a combination of first-principles calculations and the linearized phonon Boltzmann equation within the single-mode relaxation time approximation (RTA).

Thermal conductivity of ethanol

open access: yesThe Journal of Chemical Physics, 2005
We present a factorization of the Ewald sum permitting efficient computation of the reciprocal space part of the molecular representation for the heat flux vector. We use the derived expression to evaluate thermal conductivity of a model of ethanol at several near-ambient state points.
