TL;DR: In this article, the effectiveness of storing energy by compressing and expanding a condensable gas is evaluated, and a miniature lab-scale experimental setup was designed and built to investigate the compression/expansion characteristics and energy storage efficiency of a system utilizing R134a as the energy storage (primary) working fluid, and mineral refrigerant oil as the liquid piston (secondary) fluid.

TL;DR: In this paper, the thermal charging performance of paraffin wax combined with compressed expanded natural graphite foam was studied for different graphite bulk densities, and the energy storage performance was calculated to show the effects of composite thermal conductivity, graphite density, and latent heat capacity.

TL;DR: Vertical carbon nanotube (CNT) forests bonded at room temperature with sprayed on nanoscale polymer coatings are found by measurement to produce thermal resistances that are on a par with those of conventional metallic solders.

TL;DR: In this paper, the authors demonstrate a technique to quantify the magnitude of operational thermoelastic stress that evolves in a gallium nitride (GaN) transistor through simultaneous use of the Raman signal's Stokes peak position and linewidth.

TL;DR: In this paper, a thermal resistor network model was combined with a 3D finite element submodel of an LED structure to predict system and die level temperatures, and the impact of LED array density, LED power density, and active versus passive cooling methods on device operation was calculated.
