We propose to perform neutron diffraction experiments under high-pressure on multiferroic TbMnO3 using WISH in combination with hybrid-anvil-type high-pressure device. Recently,... -
Investigation into the reversibility of TiCl4 doped NaALH4 using MAPS
Hydrogen Storage still remains the technology bottleneck for a more widespread use of hydrogen. Solid complex hydrides such as amides, alanates and borohydrides have been... -
Thermal ionization of bond-centred muonium in diamond
Our previous LF-µSR measurements in natural type Ia single crystal diamond showed some evidence of the ionization of bond-centred muonium (MuBC) from around 1000K. This was... -
High-pressure and variable-temperature studies of RDX
Previous studies have suggested that a high-pressure form of the widely used secondary explosive RDX can be obtained above ~4 GPa and 488 K. This phase is reported to be... -
Melting the long-range magnetic order in SrEr2O4 with an applied magnetic field
We have observed an interesting phenomenon of the destruction of long-range magnetic order in SrEr2O4 by a relatively modest applied magnetic field. For a field applied along... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently... -
Dynamic Surface excess concentration of pH-responsive chelating surfactants
This study will examine a process of slow dynamic change in surface excess of a unique pH-responsive chelating surfactant at the air/liquid interface that occurs over a period... -

We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental... -
Divacancy superstructures and enhanced thermopower in NaxCayCoO2
Replacing Na ions in NaxCoO2 with divalent Ca ions results in the formation of ordered arrays of divacancy clusters, rather than the trivacancy clusters found for the pure... -
High Temperature Spin Transition in LaCoO3
We aim to continue our investigation of the high temperature magnetic interactions in LaCoO3. Our previous experiment has confirmed magnetic susceptibility data, with a change... -
Tuning cycloidal ordering by epitaxial strain in BiFeO3 thin films
Owing to their promising applications, especially in spintronics, multiferroics have been at theforefront of condensed matter research for a number of years. In these materials,... -
Crystal and magnetic structure of the polar ferrimagnet BaCaFe4O7
Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices; the inherent magnetoelectric effect can underpin both pyroelectric or... -
Proton Delocalization in Liquid Hydrogen Chloride
Liquid HCl has attracted numerous studies focusing onto the role played by hydrogen bonding on the dynamical properties of this weakly associated liquid. Previous computational... -
Satisfying the need for contrast in antimicrobial research
Gram-negative bacteria, which cause a variety of diseases including meningitis, plague, sepsis and food poisoning, are becoming increasingly antibiotic resistant. One reason is... -
