Elastocaloric effect in zinc oxide nanowire

Functional Materials Letters, 2021
In this work, zinc oxide (ZnO) nanowire is proposed for elastocaloric application which has been overlooked until now. The elastocaloric effect ([Formula: see text]CE) is calculated by Maxwell relation. The large elastocaloric temperature and entropy change evaluated as 17 K and 28 J/kgK, respectively, at 300 K correspond to the stress of 12 GPa or ...

Elastocaloric effects in the extreme

Scripta Materialia, 2018
Abstract There is a resurgence of interest in the elastocaloric (EC) effect of shape memory alloys (SMAs). The temperature change associated with the EC effect can be substantial, far exceeding those observed in well-known electrocaloric and magnetocaloric materials.

Elastocaloric effect in ferroelectric ceramics

Applied Physics Letters, 2015
Elastocaloric effect has been experimentally demonstrated in bulk (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 polycrystalline ferroelectric material. Predictions were made using Maxwell's relationship for elastocaloric effect. A maximum elastocaloric effect of 1.55 K was observed for an initial material temperature of 340 K and applied compressive stress of 0–250 MPa

Elastocaloric effect in bamboo-grained Cu71.1Al17.2Mn11.7 microwires

Journal of Alloys and Compounds, 2021
Abstract Bamboo-grained Cu71.1Al17.2Mn11.7 microwires with diameter ∼150 μm were created by Taylor-Ulitovsky method and subsequent annealing. The grain architecture dependent superelasticity (SE) and elastocaloric effects (eCE) were confirmed. The bamboo-grained microwires exhibited low stress hysteresis loss during SE due to the reduced constraints ...

Elastocaloric Effect in Carbon Nanotubes and Graphene

Nano Letters, 2016
Carbon nanotubes are famous for their many extraordinary properties. We use a thermodynamical approach, experimental data from the literature, and atomistic simulations to reveal one more remarkable property of the carbon nanotubes that has so far been overlooked.

Origami Metamaterials Enable Low-Stress-Driven Giant Elastocaloric Effect

ACS Nano, 2023
Elastocaloric materials, capable of achieving reversible thermal changes in response to a uniaxial stress, have attracted considerable attention for applications in advanced thermal management technologies, owing to their environmental friendliness and economic benefits. However, most elastocaloric materials operating on the basis of first/second-order

Elastocaloric effect in Ni50Fe19Ga27Co4 single crystals

Acta Materialia, 2015
Abstract The elastocaloric effect of the [0 0 1] P and [1 1 1] P orientated (subscript P represents the parent phase) Ni 50 Fe 19 Ga 27 Co 4 (at.%) single crystals exhibiting first-order martensitic transformations have been studied at temperatures of 298–448 K under different compressive stresses.

Giant elastocaloric effect in FeRh alloy

Physics Letters A, 1992
Abstract The elastocaloric effect, the electrical resistivity and the thermal expansion have been investigated in a quenched sample of Fe 49 Rh 51 alloy. The giant negative temperature change, resulting from a tensile stress of 529 MN/m 2 applied to the sample, is found to be 5.17 K.

Giant Room‐Temperature Elastocaloric Effect in Ferroelectric Ultrathin Films

Advanced Materials, 2014
Environmentally friendly ultrathin BaTiO3 capacitors can exhibit a giant stress-induced elastocaloric effect without hysteresis loss or Joule heating. By combining this novel elastocaloric effect with the intrinsic electrocaloric effect, an ideal refrigeration cycle with high performance (temperature change over 10 K with a wide working-temperature ...

Combining magnetocaloric and elastocaloric effects in a Ni45Co5Mn37In13 alloy

Journal of Materials Science & Technology, 2021
Abstract Solid-state refrigeration technology has become a promising candidate to replace the traditional low-efficiency and environment-harmful vapor compression refrigeration. However, the narrow temperature region becomes a critical problem which hinders the practical applications of caloric materials to a refrigerator. Here, we report a potential
