It has recently been discovered than the rutile phase of zinc fluoride shows negative thermal expansion along all three crystallographic axes. What is highly unusual about this...

Ionic conductivity is a property where a material is able to conduct electricity through the movement of ions. Oxide ion conductors can be used in solid oxide fuel cells, which...

New perovskite phases containing lead and halogens with a molecular cation are providing new options for materials in solar cells, giving unusually high efficiencies in...

Coordination polymers (CPs) with reversible phase changes between amorphous and crystalline states have recently become of interest for potential Phase-Change Memory...

The Zintl phase hydrides CaSiH1.3, BaSiH1.9 and SrGeH1.3 exhibit hydride anions in alkaline earth metal voids as well as hydrogen bound to the polyanions formed by silicon /...

Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped...

Alkali Lanthanide Pyrosilicates (general formula = A3LnSi2O7) are promising candidates for use as solid electrolytes in all solid state Li-ion and Na-ion batteries. To date the...

Materials that show oxide-ion mobility (solid electrolytes) and/or reversible uptake and release of oxygen (oxygen storage materials) have important uses in applications...

Hybrid organic-inorganic perovskites are interesting candidates for a range of applications, from solar cells to light emitting diodes and lasers. For the latter applications...

Electrical steels (ES) used in motors and transformers. The major challenge is to optimise themagnetic property of ES to reduce energy waste during service. The crystallographic...

We have identified a potential quantum spin liquid by tuning the magnetic interactions on a square lattice through d10-d0 cation mixing. MuSR shows dynamic magnetism down to...

Cubic cadmium(II) cyanide shows the most pronounced isotropic NTE effect known, with behaviour more than twice as extreme as that of better known materials such as ZrW2O8. This...

The next generation of Li-ion rechargeable batteries is contingent on the development of new positive electrode materials with a greater capacity to store charge. Highly ordered...

Our aim is to use total neutron scattering to determine pair distribution functions that will allow us to examine the atomic-scale structure of some new mixed-metal...

Sodium layered oxides as cathode for Na-ion battery could exceed the energy density offered by Li-ion cathode thanks to two main advantages: (i) the activation of Fe3+/Fe4+ in...

Ammonium sulfate has a well-known order-disorder phase transition at -50 ºC: initially of interest for the ferroelectric behaviour in the low-temperature phase, this has...

Proton conducting materials have received widespread attention in recent years, due to their rich potential in the areas of energy related research, sensors and membranes. Here,...

Recently, our group has prepared a series of new double perovskite materials (Li1.5La1.5MO6, M=W6+, Te6+) which display interesting electrochemical behaviour for use in Li-ion...

Mixed-anion compounds such as lanthanum oxyfluorides are increasingly attractive as materials in energy technology applications, such as fuel cells, electrolysers and permeation...

In the current work, we study inorganic solid-state electrolytes for lithium-ion batteries. These materials, unlike the traditional liquid electrolytes, could lead to a...
