An Elastocaloric Polymer with Ultra-High Solid-State Cooling via Defect Engineering. [PDF]

Adv Sci (Weinh)
This work reports a defect‐engineering strategy that enables a record‐high adiabatic temperature change of up to 8.14 ± 1.76 °C in elastomers at an elevated temperature above 65 °C. Combined experimental and theoretical efforts reveal that increasing dangling‐chain defects nonmonotonically impacts the elastocaloric cooling performance of polymers due ...

Orientation-Dependent Phase Transformation Pathways Enabling Superior Superelastic and Elastocaloric Performance of NiTi Alloys. [PDF]

Adv Sci (Weinh)
By integrating simulations and experiments, the preferred (001) crystallographic texture promotes reversible martensite formation through variant selection, enhancing both superelastic and elastocaloric performance. This work provides fundamental guidelines for designing high‐efficiency NiTi‐based functional materials. Abstract Developing elastocaloric

Elastocaloric Effect in Graphene Kirigami

Nano Letters, 2023
Kirigami, a traditional Japanese art of paper-cutting, has recently been explored for its elastocaloric effect (ECE) in kirigami-based materials (KMs), where applying strain induces temperature changes. In this study, we investigate the ECE in a nanoscale graphene kirigami (GK) monolayer, representing the thinnest possible KM, to better understand this
