Thermoelectric cooling materials

Nature Materials, 2020
Solid-state thermoelectric devices can directly convert electricity into cooling or enable heat pumping through the Peltier effect. The commercialization of thermoelectric cooling technology has been built on the Bi2Te3 alloys, which have had no rival ...

Materials in Radiative Cooling Technologies

Advances in Materials
Radiative cooling (RC) is a carbon‐neutral cooling technology that utilizes thermal radiation to dissipate heat from the Earth's surface to the cold outer space. Research in the field of RC has garnered increasing interest from both academia and industry

The effect of misalignment on the performance of tilting pad thrust bearing with TEHD coupling model and turbulence model

Advances in Mechanical Engineering, 2023
A thermoelastohydrodynamic (TEHD) coupling model is developed to study the static performance of a heavy-duty tilting pad thrust bearing (TPTB) under the effect of axis misalignment.

A dual-selective thermal emitter with enhanced subambient radiative cooling performance

Nature Communications
Radiative cooling is a zero-energy technology that enables subambient cooling by emitting heat into outer space (~3 K) through the atmospheric transparent windows. However, existing designs typically focus only on the main atmospheric transparent window (

Computational fluid dynamics model for a variable conductance thermosyphon

Case Studies in Thermal Engineering, 2021
A variable conductance thermosyphon is a unique type of heat pipe that responds passively to changes in thermal environment because of the presence of non-condensable gas (NCG).
