Colossal and reversible barocaloric effect in liquid-solid-transition materials n-alkanes. [PDF]

Nat Commun, 2022
Barocaloric effect, previously reported in solid-solid phase transition materials, offers a green alternative to current cooling technology. Here the authors report colossal BCE in n-alkanes associated with liquid–solid transition.

Ultrasensitive barocaloric material for room-temperature solid-state refrigeration. [PDF]

Nat Commun, 2022
A small driving pressure is desirable for practical application of barocaloric materials. Here, the authors demonstrate a sensitive barocaloric effect in NH4I due to strong reorientation-vibration coupling.

Low pressure reversibly driving colossal barocaloric effect in two-dimensional vdW alkylammonium halides. [PDF]

Nat Commun
Plastic crystals as barocaloric materials exhibit the large entropy change rivalling freon, however, the limited pressure-sensitivity and large hysteresis of phase transition hinder the colossal barocaloric effect accomplished reversibly at low pressure.

High-Efficiency Thermal Battery Regulated by Ultralow Magnetic Fields. [PDF]

Small Sci
A magneto‐responsive composite is reported that, for the first time, achieves a noncontact phase transition with an ultralow magnetic field (≈0.04 T). It exhibits a colossal entropy change of ≈507.6 J kg−1 K−1, an enthalpy of 181.1 J g−1, and a ≈47.6 K temperature rise, alongside enhanced thermal conductivity and heat‐release efficiency, making it ...

All-temperature barocaloric effects at pressure-induced phase transitions. [PDF]

Nat Commun
Caloric effects, which underpin one solution to solid-state refrigeration technologies, usually occur in the vicinity of solid-state phase transitions with a limited refrigeration temperature span. Here, we introduce and realize an unprecedented concept ‒

Simple and Low-Cost Footstep Energy-Recover Barocaloric Heating and Cooling Device. [PDF]

Materials (Basel), 2021
[Abstract] In this work, we design, build, and test one of the very first barocaloric devices. The here presented device can recover the energy generated by an individual’s footstep and transform it into barocaloric heating and/or cooling.
