Enhancing Elastocaloric Strength by Combining Positive and Negative Elastocaloric Effects
SSRN Electronic Journal, 2022Solid‐state refrigeration has received widespread attention recently because of its high refrigeration efficiency and environmental protection. Compared with other solid‐state refrigeration technologies, elastocaloric effects have great application potential. However, the current temperature change of elastocaloric effects is still low.

Elastocaloric effect in zinc oxide nanowire
Functional Materials Letters, 2021In 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, 2018Abstract 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, 2015Elastocaloric 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, 2021Abstract 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, 2016Carbon 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, 2023Elastocaloric 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

Giant elastocaloric effect in FeRh alloy
Physics Letters A, 1992Abstract 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.
