Phase transitions in non-centrosymmetric Dion-Jacobson Phases
Ferroelectric materials - those which exhibit a spontaneous and switchable electrical polarization - have a wide range of applications. However materials which exhibit... -
The local structure in high-entropy alloy deuterides probed by neutron total ...
High-entropy alloys (HEAs) typically contain four or more principle elements in approximately equimolar amounts. It was recently discovered by the co-proposer that a... -
High resolution INS spectra of hydrocarbonaceous overlayers formed on novel m...
For the first time, the research team aim to use INS to characterise a series of new high specification methane reforming catalysts. The enhanced performance of these catalysts... -
Structure of novel silica-free titanate glasses
Silica-free barium titanate bulk glasses, containing lanthanide elements, show unusually high dielectric response and a high refractive index. These properties allow crucial... -

The LaFe13-xSix system (x<1.6) has a first order ferromagnetic, FM, to paramagnetic, PM, transition that is tunable in magnetic field, ending at a (tri)critical point (Hcrit,... -
Fragile to strong transition in concentrated sorbitol-water solutions
In a recent paper [J. Phys. Chem. B, 2016, 120 (29), pp 72897296] we have put forward the idea that water in concentrated (70 wt%) sorbitol-water solutions becomes confined by... -
Understanding Chemical Expansion in Perovskite Oxides: Impact of Long-Range D...
"Chemical expansion" occurs when some ceramics expand upon releasing oxygen. Their ability to effectively "breathe" oxygen makes them of use in sustainable energy...
