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…

On (not) deriving the entropy of barocaloric phase transitions from crystallography and neutron spectroscopy

Anthony E. Phillips, Helen C. Walker

We review well-known signatures of disorder in crystallographic and inelastic neutron scattering data. We show that these can arise from different types of disorder, corresponding…

Dynamics in the ordered and disordered phases of barocaloric adamantane

Bernet E. Meijer, Richard J. C. Dixey, Franz Demmel +3

High-entropy order-disorder phase transitions can be used for efficient and eco-friendly barocaloric solid-state cooling. Here the barocaloric effect is reported in an archetypal p…

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…

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…
