The Thermal Conductivity of Oxygen

Journal of Research of the National Bureau of Standards, 1982
The paper presents new experimental measurements of the thermal conductivity of oxygen for thirteen isotherms at temperatures from 78 to 310 K with pressures to 70 MPa and densities from 0 to 40 mol/L. The measurements were made with a transient hot wire apparatus and they cover a wide range of physical states including the dilute gas, the moderately ...

Thermal Conductance of Andreev Interferometers [PDF]

Physical Review Letters, 2005
We calculate the thermal conductance $G^T$ of diffusive Andreev interferometers, which are hybrid loops with one superconducting arm and one normal-metal arm. The presence of the superconductor suppresses $G^T$; however, unlike a conventional superconductor, $G^T/G^T_N$ does not vanish as the temperature $T\to0$, but saturates at a finite value that ...

Low thermal conductivity of the layered oxide (Na,Ca)Co_2O_4: Another example of a phonon glass and an electron crystal

, 2000
The thermal conductivity of polycrystalline samples of (Na,Ca)Co_2O_4 is found to be unusually low, 20 mW/cmK at 280 K. On the assumption of the Wiedemann-Franz law, the lattice thermal conductivity is estimated to be 18 mW/cmK at 280 K, and it does not ...

A Novel Digitalization Approach for Smart Materials – Ontology‐Based Access to Data and Models

Advanced Engineering Materials, EarlyView.
In order to access heterogeneous material data and model‐based knowledge, the established ontology‐based data access (OBDA) is extended to include material models. This novel ontology‐based data and model access (OBDMA) enables the computation of new responses beyond stored data.

Effect of electrically aligned polycrystalline diamond flakes on the through-plane thermal conductivity of heat conduction sheets

Functional Diamond
Heat conduction sheets, which are composed of a thermally conductive filler and a base elastomer matrix, are important for dissipating heat from devices to a heat sink.

Continuous Wave Mode Test of Conduction-Cooled Nb₃Sn Radio Frequency Superconducting Cavities at Peking University

Applied Sciences
A liquid helium-free cryostat for radio frequency (RF) test of the superconducting cavity is designed and constructed. Gifford-Mcmahon (G-M) cryocoolers are used to provide cooling capacity, and the heat leakage at 4 K is less than 0.02 W.

Spherical Accretion with Anisotropic Thermal Conduction

, 2008
We study the effects of anisotropic thermal conduction on magnetized spherical accretion flows using global axisymmetric MHD simulations. In low collisionality plasmas, the Bondi spherical accretion solution is unstable to the magnetothermal instability (

Multifunctional Design of Triply Periodic Minimal Surface Structures for Temporary Pediatric Fixation Devices

Advanced Engineering Materials, EarlyView.
A metallic implant's higher stiffness compared to the surrounding bone leads to stress shielding problems, causing bone density reduction and bone growth interference in pediatric patients. 3D‐printed triply periodic minimal surface structures present a promising engineering solution.

Thermal conductance of zero modes on the surface boundary of a Weyl semimetal [PDF]

arXiv, 2018
Thermoelectric conductance of Dirac materials and in particular zero modes reveals the effect of topology .Weyl semimetals with a boundary at z = 0 give rise to chiral zero modes with- out backscattering resulting in a significant contribution to thermal conductivity. By doping the surface with paramagnetic impurities backscattering is allowed, and the
