Flexoelectric Elastomer Enabled by Miscibility‐Driven Succinonitrile Molecular Rotation
Advanced Science, Volume 13, Issue 5, 27 January 2026.A flexoelectric material platform is developed by embedding polar plastic crystals into polymer networks. By tuning the microstructure and preserving molecular rotation, strain gradient‐induced polarization is achieved. The resulting elastomer shows scalable and tunable electromechanical output under mechanical deformation, offering a new design route ...

Magnetocaloric and barocaloric responses in magnetovolumic systems [PDF]
Physical Review B, 2015 By means of a mean-field model extended to include magnetovolumic effects we study the effect of external fields on the thermal response characterized either by the isothermal entropy change and/or the adiabatic temperature change. The model includes two different situations induced by the magnetovolumic coupling.

Small Structures, Volume 7, Issue 1, January 2026.Microstructure engineering is utilized to control martensitic transformation of all‐d‐metal alloys and is directly observed via in situ Lorentz transmission electron microscopy. The appearance of magnetic vortexes and its evolution not only highlight a new potential application scenario for Ni–Co–Mn–Ti alloy in magnetic storage but also reveal the ...

Solid-State Heating Using the Multicaloric Effect in Multiferroics
Magnetochemistry, 2021 The multicaloric effect is defined as the adiabatic reversible temperature change in multiferroic materials induced by the application of an external electric or magnetic field, and it was first theoretically proposed in 2012. The multicaloric effects in

Fantastic barocalorics and where to find them
Applied Physics Letters, 2021 Barocaloric materials have the potential to offer greener and more efficient alternatives to conventional refrigerants that exploit vapor compression for cooling and heating applications. The barocaloric effect, a temperature change in response to hydrostatic pressure, is widespread in materials; however, only in the last few years have giant and ...

Barocaloric effect in ferroelastic fluorides and oxyfluorides [PDF]
Ferroelectrics, 2016 Using the data about the temperature - pressure phase diagram and the phase transition entropy at ambient and high pressure, intensive and extensive barocaloric effects were analyzed in the region of single and successive order-disorder phase transitions in fluorides and oxyfluorides with the elpasolites-cryolite structure.

Dynamics in the ordered and disordered phases of barocaloric adamantane
Physical Chemistry Chemical Physics, 2023 The archetypal plastic crystal adamantane has ideal properties for low-temperature barocaloric cooling. Its large entropy change is explained in terms of differences between the molecular dynamics in the ordered and disordered phases.

Small, Volume 21, Issue 50, December 17, 2025.Temperature‐controlled in situ desolvation within the vacuum chamber of a dedicated electron diffractometer is shown to enable precise characterization of structural changes in flexible MOFs. Characterization of transient intermediate states of MIL‐53(Cr) and MIL‐53(Ga) at different levels of openness by 3D electron diffraction shows they undergo metal‐

Angewandte Chemie, Volume 136, Issue 41, October 7, 2024.Femtosecond infrared spectroscopy is used to study the out‐of‐equilibrium dynamics of the ultrafast and persistent photoinduced phase transition of the Rb0.94Mn0.94Co0.06[Fe(CN)6]0.98 ⋅ 0.2H2O material, induced at room temperature. The data show that optical excitation creates small CT polarons within 250 fs.
