Anisotropic and inhomogeneous thermal conduction in suspended thin-film polycrystalline diamond
While there is a great wealth of data for thermal transport in synthetic diamond, there remains much to be learned about the impacts of grain structure and associated defects and impurities within a few microns of the nucleation region in films grown ...

Effects of anisotropic thermal conduction on wind properties in hot accretion flow [PDF]
Previous works have clearly shown the existence of winds from black hole hot accretion flow and investigated their detailed properties. In extremely low accretion rate systems, the collisional mean-free path of electrons is large compared with the length-

Electrical conduction processes in ZnO in a wide temperature range 20--500 K
We have investigated the electrical conduction processes in as-grown and thermally cycled ZnO single crystal as well as as-grown ZnO polycrystalline films over the wide temperature range 20--500 K. In the case of ZnO single crystal between 110 and 500 K,

Thermal conductivity of supercooled water [PDF]
The heat capacity of supercooled water, measured down to -37 C, shows an anomalous increase as temperature decreases. The thermal diffusivity, i. e., the ratio of the thermal conductivity and the heat capacity per unit volume, shows a decrease. These anomalies may be associated with a hypothetical liquid-liquid critical point in supercooled water ...

First-Principles Study of Lattice Thermal Conductivity of Td-WTe2 [PDF]
The structural and thermal properties of bulk Td-WTe2 have been studied by using first-principles calculations. We find that the lattice thermal conductivity of WTe2 is anisotropic, with the highest value along a-axis and lowest one along the c-axis at 300 K.

Surge current and electron swarm tunnel tests of thermal blanket and ground strap materials [PDF]
The results are described of a series of current conduction tests with a thermal control blanket to which grounding straps have been attached. The material and the ground strap attachment procedure are described. The current conduction tests consisted of

Dimensional crossover of thermal conductance in nanowires [PDF]
Dimensional dependence of thermal conductance at low temperatures in nanowires is studied using the nonequilibrium Green's function (NEGF) method. Our calculation shows a smooth dimensional crossover of thermal conductance in nanowire from one-dimensional to three-dimensional behavior with the increase of diameters.

Ultrahigh thermal conductivity in hexagonal BC6N- An efficient material for nanoscale thermal management- A first principles study [PDF]
Engineering materials with high thermal conductivity are of fundamental interest for efficiently dissipating heat in micro/nanoelectronics. Using first principles computations we report an ultra-high thermal conductivity of 2090 Wm-1K-1 (1395 Wm-1K-1) for hexagonal pure (natural) BC6N(h-BC6N).
