Elastocaloric Effect in Graphene Kirigami [PDF]
Nano letters (Print), 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.

Giant elastocaloric effect at low temperatures in TmVO4 and implications for cryogenic cooling. [PDF]
Proc Natl Acad Sci U S A, 2023 Adiabatic decompression of para-quadrupolar materials has significant potential as a cryogenic cooling technology. We focus on TmVO$_4$, an archetypal material that undergoes a continuous phase transition to a ferroquadrupole-ordered state at 2.15 K ...

Elastocaloric signature of nematic fluctuations. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance In an electron-nematic state, electronic correlations spontaneously break the rotational symmetry of the underlying lattice. Associated fluctuations occur in a wide range of quantum materials including high-temperature superconductors. While

Large Cyclability of Elastocaloric Effect in Highly Porous Ni-Fe-Ga Foams. [PDF]
Materials (Basel)Solid-state refrigeration based on elastocaloric materials (eCMs) requires reversibility and repeatability. However, the intrinsic intergranular brittleness of ferromagnetic shape memory alloys (FMSMAs) limits fatigue life and, thus, is the crucial ...

Orientation dependent cyclic stability of the elastocaloric effect in textured Ni-Mn-Ga alloys
AIP Advances, 2018 High-performance elastocaloric materials require a large reversible elastocaloric effect and long life cyclic stability. Here, we fabricated textured polycrystalline Ni50.4Mn27.3Ga22.3 alloys by cost-effective casting method to create a texture.

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