Wireless Temperature-Sensing System for Liquid-Nitrogen Biobanks

Liquid-nitrogen biobanks need temporary, spatially distributed temperature records, but conventional batteries and radios become unreliable far below their rated operating temperatures. We developed a finite-duration wireless logging system that separates sensing and communicatio...

Electrode placement effects on Joule heating and thermal uniformity in an AC zinc-smelting furnace

The steady electrothermal behavior of AC zinc-smelting furnaces is governed by current redistribution and Joule-heat localization, which directly affect bath-temperature uniformity and refractory thermal loading. A three-dimensional one-way coupled electromagnetic-thermal-flow mo...
