  • A new type of solid-sate colossal barocaloric material was fabricated by exploiting the amorphous high entropy inherited from huge disorder of liquid phase in solidified PEG(HO(CH2CH2O)nH) by introducing 5 wt.% PET((C10H8O4)m) for copolymerization. Although PEG loses –OH end mobility, high entropy still retains in amorphous solid. Consequently, a colossal barocaloric entropy change as high as ΔSp ∼ 416 J·kg−1·K−1 under a low pressure of 0.1 GPa was demonstrated.

  • In this study, the authors report the development of an inhalable IgM-like ACE2 and show that it broadly neutralizes SARS-CoV-2 variants, lowers viral loads and lung pathology in hamsters when administered early, and has good safety profiles in rats and monkeys.

  • For the emergent colossal, reversible barocaloric effect in organic–inorganic perovskite hybrids (CH3–(CH2)n−1–NH3)2MnCl4 (n = 9, 10), we successfully grew a single crystal, and the underlying mechanism was determined by high-resolution SC-XRD, IR spectroscopy and DFT calculations. The drastic transformation of organic chains confined to the metallic frame from ordered rigidity to disordered flexibility is responsible for the large phase-transition entropy, which is comparable to the melting entropy of organic chains. The result provides new insights into designing novel barocaloric materials by utilizing the disordering of organic chains of organic–inorganic hybrid materials.
