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

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.
