Ultrasensitive barocaloric material for room-temperature solid-state refrigeration [PDF]

open access: yesNature Communications, 2022
A small driving pressure is desirable for practical application of barocaloric materials. Here, the authors demonstrate a sensitive barocaloric effect in NH4I due to strong reorientation-vibration coupling.

Advanced materials for solid-state refrigeration [PDF]

open access: yesJournal of Materials Chemistry A, 2013
Recent progress on caloric effects are reviewed. The application of external stimuli such as magnetic field, hydrostatic pressure, uniaxial stress and electric field give rise respectively to magnetocaloric, barocaloric, elastocaloric and electrocaloric ...
