This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well...

Modulation has been understood and used to explain physical properties in solid-state materials for many years. Molecular modulated structures relatively scarce, but due to...

Water is the most fundamental hydrogen-bonded compound on Earth and its physical properties are essential for research areas ranging from live sciences to planetology. In this...

As it was reported recently in Nature Hydrogen sulphide conducts electricity with zero resistance at a record high temperature of 203 K. Authors of this high profile discovery...

Equations of state (EoSs) show how the thermodynamic variables of temperature, pressure and volume are inter-related. The ideal gas law, PV = nRT, is an example of an EoS which...

When synthesised at high pressure and temperature, holmium germanate adopts the pyrochlorestructure. Because of its geometry, materials with this structure often have exotic and...

The mantle is estimated to be planet Earth’s most massive volatile (e.g. H, C, S, N) storage reservoir, with interactions between crustal and mantle reservoirs dominate the...

BaTiO3 is often thought of as the classic example of a ferroelectric material, with a well-defined, widely-taught phase diagram. However, the nature of the ferroelectric phase...

The superconducting material La2-xBaxCuO4 (LBCO) exhibits an anomalous dip in Tc at the x = 0.125 composition at low temperature (>30 K). This is at odds with other...

Lead based ferroelectric perovskite structured materials are extensively used in industrial applications. However, as a result of the need for more environmentally friendly...

We have found that the 134-perovskite, HgMn7O12 (HgAMnA’3MnB4O12) exhibits improper ferroelectric coupling due to an unusual orbital ordering of the manganese cations on both...

Simple hydrides are of scientific interest due to their suitability for storage of hydrogen in the solid state. These materials also display a wealth of interesting physics,...

We propose to study the effect of pressure on the structure of the tetragonal Ba0.575Sr0.425SnO3, The behaviour will be compared to the compression of the cubic BaSnO3 (parent...

Ammonium bromide is a fundamental ionic solid that finds practical use, industrially, as a highly-effective flame retardant and also as an intermediary source of bromide in...

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...

Though the beta and gamma forms of the simplest amino acid, glycine, yield a variety of different phases on application of pressure, Raman data suggest that the most common...
