The mechanocaloric effect is the temperature change of a material upon application or removal of an external stress. Beyond its fundamental interest, this caloric response represents a promising and ecofriendly alternative to current cooling technologies. To obtain large mechanocaloric effects, we need materials whose elastic properties (e.g., strain, elastic compliance) are strongly temperature dependent. This is the case of ferroelectric perovskite oxides, where the development of the…

Combined intrinsic elastocaloric and electrocaloric properties of ferroelectrics
In multiferroic materials, adiabatic temperature changes can be obtained by the combined application of electric, stress, and magnetic fields. These external stimuli provide additional channels of
A unified perturbative approach to electrocaloric effects
The electrocaloric effect, that is, the temperature change experienced by an insulator upon application of an electric field, offers promising ecofriendly alternatives to refrigeration. However, the
Negative capacitance in multidomain ferroelectric superlattices
First-principles-based atomistic simulations provide detailed microscopic insight into the origin of this phenomenon, identifying the dominant contribution of near-interface layers and paving the way for its future exploitation.
Elastocaloric switching effect induced by reentrant martensitic transformation
Vapor compression technologies widely used for refrigeration, heating, and air-conditioning have consumed a large fraction of global energy. Efforts have been made to improve the efficiency to save
Giant solid-state barocaloric effect in the Ni-Mn-In magnetic shape-memory alloy.
It is shown that the application of a moderate hydrostatic pressure to a magnetic shape-memory alloy gives rise to a caloric effect with a magnitude that is comparable to the giant magnetocaloric effect reported in this class of materials.
Giant barocaloric effects over a wide temperature range in superionic conductor AgI
Giant inverse barocaloric effects are demonstrated in the solid electrolyte AgI, near its superionic phase transition at ~420 K, resulting in large values of refrigerant capacity and the peak values of isothermal entropy change and adiabatic temperature changes exceed all values previously recorded for barocalic materials.
Electrocaloric Effect: Theory, Measurements, and Applications
The electrocaloric effect (ECE) is a physical phenomenon found in materials with dipolar constituents, that is, with certain dielectric properties. It is manifested in the heating or cooling of an
Reduced dimensions elastocaloric materials: A route towards miniaturized refrigeration
Abstract Elastocaloric cooling technology has obtained huge attraction over vapor compression systems because it is more efficient with negligible environmental impact. The elastocaloric effect (eCE)
Negative thermal expansion in functional materials: controllable thermal expansion by chemical modifications.
NTE is reviewed in functional materials of ferroelectrics, magnetics, multiferroics, superconductors, temperature-induced electron configuration change and so on, in which NTE is determined by either ferroelectric order or magnetic one.
Colossal barocaloric effects near room temperature in plastic crystals of neopentylglycol
This work shows that plastic crystals of neopentylglycol (CH3)2C(CH2OH)2 display extremely large pressure-driven thermal changes near room temperature due to molecular reconfiguration, and that these changes are comparable with those exploited commercially in hydrofluorocarbons.
