Understanding colossal barocaloric effects in plastic crystals. [PDF]
Nat Commun, 2020 AbstractPlastic crystal neopentylglycol (NPG) exhibits colossal barocaloric effects (BCEs) with record-high entropy changes, offering exciting prospects for the field of solid-state cooling through the application of moderate pressures. Here, we show that the intermolecular hydrogen bond plays a key role in the orientational order of NPG molecules ...

Colossal barocaloric effects in the complex hydride Li[Formula: see text]B[Formula: see text]H[Formula: see text]. [PDF]
Sci Rep, 2021 AbstractTraditional refrigeration technologies based on compression cycles of greenhouse gases pose serious threats to the environment and cannot be downscaled to electronic device dimensions. Solid-state cooling exploits the thermal response of caloric materials to changes in the applied external fields (i.e., magnetic, electric and/or mechanical ...

Colossal Barocaloric Effects at Triple‐Phase Points
ENERGY & ENVIRONMENTAL MATERIALSBarocaloric effect underlies a promising emission‐free and highly efficient cooling technology. The current wisdom to design barocaloric materials is to find materials undergoing a temperature‐induced phase transition with huge latent heats and then to apply a pressure to harvest the heat.

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