Tunability of terahertz random lasers with temperature based on superconducting materials [PDF]

, 2012
We theoretically demonstrate the tunabiltiy of terahertz random lasers composed of high temperature superconductorYBCO and ruby layers as active medium. The considered system is a one-dimensional disordered medium made of ruby grain and YBCO.

Effect of Internal AC Heating on the Temperature Homogeneity of Different Size Battery Cells

Batteries, 2022
Rapidly warming up batteries is an important challenge both for conventional lithium-ion batteries, which operate best over 15 °C, and for most solid-state batteries, which currently require operating temperatures over 60 °C.
