Hidden in-plane long-range order in an amorphized crystal
Yin Chen, Anthony E. Phillips, Cheng Fu +12
Solid materials are commonly classified as crystalline or amorphous based on the presence or absence of long-range order.Metal-organic frameworks (MOFs), like other solids,also dis…
Pressure dependence of atomic dynamics in barocaloric ammonium sulfate: II. Vibrations
Shurong Yuan, Bernet E. Meijer, Guanqun Cai +3
Ammonium sulfate is a giant inverse barocaloric material that is cheaply and commercially available. Exploiting its potential for cooling applications requires an understanding of…
Pressure dependence of atomic dynamics in barocaloric ammonium sulfate: I. Rotations
Bernet E. Meijer, Guanqun Cai, Franz Demmel +2
Solid-state cooling using barocaloric materials is a promising avenue for eco-friendly, inexpensive and highly efficient cooling. To design barocaloric compounds ready for deployme…
Origin of the large entropy change in the molecular caloric and ferroelectric ammonium sulfate
Bernet E. Meijer, Shurong Yuan, Guanqun Cai +7
The deceptively simple inorganic salt ammonium sulfate undergoes a ferroelectric phase transition associated with a very large entropy change and both electrocaloric and barocalori…
Atomic structure of the continuous random network of amorphous C[(C6H4)2]2, PAF-1
Guanqun Cai, He Lin, Ziqiang Zhao +11
We demonstrate that the amorphous material PAF-1, C[(C6H4)2]2, forms a continuous random network in which tetrahedral carbon sites are connected by 4,4'-biphenyl linkers. Experimen…
Colossal pressure-induced softening in scandium fluoride
Zhongsheng Wei, Lei Tan, Guanqun Cai +4
The counter-intuitive phenomenon of pressure-induced softening in materials is likely to be caused by the same dynamical behaviour that produces negative thermal expansion. Through…
Hydrogen-bond-mediated structural variation of metal guanidinium formate hybrid perovskites with unit cell volume
Zhengqiang Yang, Guanqun Cai, Craig L. Bull +4
The hybrid perovskites are coordination frameworks with the same topology as the inorganic perovskites, but with properties driven by different chemistry, including host-framework…
