Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this...

Materials that show fast oxide ion conduction have potential applications as electrolytes in devices such as solid oxide fuel cells (SOFCs), gas sensors and gas separation...

Thermal, magnetic, neutron and muSR measurements all point towards a gapless or almost gapless spin liquid ground state for the triangular lattice spin system of S=1/2 Mo3...

Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations...

Mg-sulfate 11-hydrate (meridianiite) is decomposed by pressure to form Mg-sulfate 9-hydrate + ice, a process that will occur in the mantles of large icy planetary bodies and...

We seek to investigate the non-equilibrium phenomena of a model polymer mixture by time-solved SANS and temperature jump experiments within (a) one-phase region and (b) one to...

Through a combination of small angle neutron scattering, ion-beam analysis and ellipsometry we have recently demonstrated that in organic photovoltaic devices (OPVs) the...

YbPd crystallizes in the cubic CsCl-type structure and reported to have magnetically ordered ground state with the mixed valence of the Yb ion. Further, it under goes through...

Calcium carbonates make up some of the most abundant minerals in the world. They are of great importance in geology and in the field of biomaterials as well as having several...

After an almost forty year lull in research on multiferroic materials, there has been a resurgence of interest in them. However, it is particularly challenging to synthesize a...

Transition metal oxynitrides with the perovskite structure type are an emerging class of functional materials with a variety of interesting optical, photocatalytic, dielectric...

Quantum spin liquids (QSL) are new and exotic states of matter that in 2 dimensions were proposed by Anderson to underpin the transition to unconventional superconductivity of...

The structures of two binary metal carbonyls containing a metal-metal bond Mn2(CO)10 and Re2(CO)10 will be studied as a function of pressure. Both these molecules undergo a...

BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature...

PbCoO3 used to be the “missing link” in the PbMO3 perovskite series. PbCoO3 was recently synthesized by the Azuma group using high-pressure synthesis at 12 GPa. NPD at JPARC...

YbAl3C3 undergoes a structural phase transition at 80 K and a spin-dimer formation below 10K. To gain more information on the nature of the spin-dimer state and the phase...

Over the past few years, extensive developments have been made in the use of neutron diffraction for structural studies of liquids and amorphous materials at high pressure....

For total diffraction measurements using neutrons it is important to correct the data for inelasticity effects, especially for samples containing light atoms. Conventionally...

Optimising catalyst lifetime and performance is pivotal to enhancing the sustainability of industrial catalytic processes, allowing greater product yields, at lower...

An induction furnace has been developed for POLARIS. It has been tested at ISIS for 3 month during which it has passed all safety test required to be tested in beam. Currently...
