Thermal Characterization of Microscale Heat Convection under Rare Gas Condition by a Modified Hot Wire Method

open access: yes, 2017
As power electronics shrinks down to sub-micron scale, the thermal transport from a solid surface to environment becomes significant. Under circumstances when the device works in rare gas environment, the scale for thermal transport is comparable to the ...

Thermal generation of the magnetic field in the surface layers of massive stars

open access: yes, 2017
A new magnetic field-generation mechanism based on the Nernst effect is considered in hot massive stars. This mechanism can operate in the upper atmospheres of O and B stars where departures from the LTE form a region with the inverse temperature ...

Solar modulation of atmospheric electrification through variation of the conductivity over thunderstorms [PDF]

open access: yes
It is suggested that variations of the current in the global atmospheric electrical circuit can be produced through regulation of the resistance between the tops of thunderclouds and the ionosphere.

Low conductance of the nickel atomic junctions in hydrogen atmosphere

open access: yes, 2016
The low conductance of nickel atomic junctions in the hydrogen environment is studied using the nonequilibrium Green's function theory combined with first-principles calculations. The Ni junction bridged by a $H_2$ molecule has a conductance of approximately 0.7 $G_0$.
