The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we...

The study of the interaction mechanisms between water and layered silicates is central to the evaluation of the physicochemical properties of these materials, and it is an...

The catanionic vesicles are unilamellar or multilamellar spheroid structure composed of cationic and anionic surfactant molecules assembled into bilayers. Vesicles forms by...

Pharmaceuticals are usually formulated in the crystalline state for obvious reasons of stability. They may also exist in a disordered and less cohesive state i.e. amorphous...

Cubic alpha-ZrW2O8 is the classic example of a material exhibiting the unusual property of negative thermal expansion (NTE). Despite this effect having been discovered 20 years...

Ammonium carbonates, sensu lato, have relevance to carbon capture schemes and as potential hydrogen storage materials. These compounds occur on Earth as minerals and, since...

This proposal will enable us to study the dynamics of an important water soluble pesticide molecule, paraquat, in solution and in the interlayer region of swelling...

The present proposal is to examine the low temperature structural properties of SrSnO3 using the HRPD. This work aims to examine the structural basis for the unusual low...

KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling...

We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a...

Lu and Ho counterparts of RE3Fe5O12 will be an appropriate platform to reveal the complexmagnetic ground state of rare earth iron garnets with common formula RE3Fe5O12. Lu3+...

High resolution powder diffraction data will be used to obtain lattice parameter and atomic coordinate variations as a function of temperature for Pr0.6Ca0.4MnO3, which has a...

20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid....

This proposal seeks to investigate the effect of temperature on the structures of thallium and caesium azide. High-resolution neutron powder diffraction data are necessary to...

This proposal will enable us to study the dynamics of an important water soluble pesticide molecule, paraquat, in solution and in the interlayer region of swelling...

KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling...

Manganites show promise as magnetocaloric materials - for use in solid-state refrigeration - in terms of cost, durability and tunable thermal conductivity. By tuning the...

The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in...
