Elastocaloric, barocaloric and magnetocaloric effects in spin crossover polymer composite films [PDF]

Nature Communications
Giant barocaloric effects were recently reported for spin-crossover materials. The volume change in these materials suggests that the transition can be influenced by uniaxial stress, and give rise to giant elastocaloric properties.

Solid-state cooling by elastocaloric polymer with uniform chain-lengths [PDF]

Nature Communications, 2022
The elastocaloric effect was originally found in natural rubber, but the development of polymer based elastocaloric cooling still remains underdeveloped. Herein, the authors demonstrate that polymer elastomers with uniform molecular chain-lengths exhibit

The effect of Tb substitution for Ni on microstructure, martensitic transformation and cyclic stability of elastocaloric effect in Ni–Mn–Sn magnetic shape memory alloys

Journal of Materials Research and Technology, 2022
Cyclic stability of elastocaloric effect is the key factor that restricts the elastocaloric cooling application of Ni–Mn–Sn alloys fabricated by the conventional melting technique.

Investigation of the elastocaloric effect in laser powder bed fusion NiTi porous structures

Additive Manufacturing Letters, 2023
The endothermic reversible martensitic phase change in NiTi has the potential to be used for refrigeration. However, to have high efficiency in the elastocaloric effect, NiTi materials with a large surface area are required.

Elastocaloric effect of shape memory polymers in elastic response regime

JPhys Energy, 2023
Solid-state cooling/heating technology based on the elastocaloric effect is one of the promising alternatives to vapor compression systems. Large elastocaloric temperature modulation is often generated through the non-linear strain-induced structural ...

Caloric effects around phase transitions in magnetic materials described by ab initio theory : the electronic glue and fluctuating local moments [PDF]

, 2020
We describe magneto-, baro-, and elastocaloric effects (MCEs, BCEs, and eCEs) in materials, which possess both discontinuous (first-order) and continuous (second-order) magnetic phase transitions.

Evidence for realignment of the charge density wave state in ErTe$_3$ and TmTe$_3$ under uniaxial stress via elastocaloric and elastoresistivity measurements

, 2022
We report the evolution of a charge density wave (CDW) state in the quasi-2D rare-earth tritellurides ($R$Te$_3$ for $R$=Er,Tm) as a function of in-plane uniaxial stress.
