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…
Soft mode anisotropy in negative thermal expansion material ReO
Tobias A. Bird, Mark G. L. Wilkinson, David A. Keen +5
We use a symmetry-motivated approach to analyse neutron pair distribution function data to investigate the mechanism of negative thermal expansion (NTE) in ReO. This analysis s…
Atomic structure of CdS magic-size clusters by X-ray absorption spectroscopy
Ying Liu, Lei Tan, Giannantonio Cibin +5
Magic-size clusters are ultra-small colloidal semiconductor systems that are intensively studied due to their monodisperse nature and sharp UV-vis absorption peak compared with reg…
Collective modes and gapped momentum states in liquid Ga: experiment, theory and simulation
Ramil M. Khusnutdinoff, Cillian Cockrell, Oliver A. Dicks +7
Collective excitations in liquids are important for understanding liquid dynamical and thermodynamic properties. Gapped momentum states (GMS) are a notable feature of liquid dynami…
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…
