QENS studies of nanostructured hydrides
The search for a light, high-capacity hydrogen store continues. Ammonia borane (AB) is a complex hydride with excellent hydrogen capacity, of which half desorbs at moderate... -
Structural Investigations of Mixed-anion Argyrodites
Argyrodites exhibit promising thermoelectric (TE) properties but a structural transition causes cracking of ingots on cooling to ambient temperature, introducing problems for... -

Understanding the effects of pressure and temperature on the structure of an ...
The discovery of superconductivity in iron-pnictide materials has generated much excitement in the past year about possibly unifying mechanisms for high-temperature... -
Development of thermal microstress and microstrain in polycrystalline zinc: p...
Thermal microstress and microstrain develop in polycrystalline zinc powder particles due to anisotropic thermal expansion, as revealed by corresponding diffraction-line... -
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... -
Stochastic vs. Intermolecular Motions in Strongly Associated Liquids: The Cas...
Neutron scattering is a powerful technique to study stochastic motions in liquids but it requires an energy resolution well below the meV range. As a consequence, quasielastic... -
Cooperative Jahn-Teller distortions in Ru4+ double perovskites
The aim of the proposed experiment is to use HRPD to follow the temperature dependence of the crystal structures of the double perovskites La2MgRuO6 and La2CoRuO6. This is of... -
Direct measurement of the nuclear momentum distribution in a switchable diele...
The family of hybrid Prussian blue analogues includes many electroactive materials, where organic cations moving within the pores of the cyanide framework cause unusual and... -
Polymorphism of phenytoin at low temperature
Phenytoin is a simple organic pharmaceutical material that exhibits a phase transition at low temperature to a new phase. The high temperature form exhibits some unusual... -
Magnetic structure of the potential multiferroic GdCrO3
Because of the potential applications of multiferroicity, the discovery of a new multiferroic (MF) material is invariably met with great enthusiasm in the condensed matter... -
The charge-ordered superstructure of YbFe2O4
There has been much recent interest in the so-called ¿novel¿ or ¿type-II¿ multiferroics, in which electrical polarisation appears at the onset of a particular type of magnetic... -

Detecting quantum critical fluctuations in the distorted kagome Kondo compoun...
Geometrically frustrated spin systems have been studied extensively for decades because of many intriguing phenomena, exemplified by the non-magnetic quantum disordered states.... -
Dynamics studies of water and ice in carbon nanohorns
Recent diffraction [GEM] and DINS [Vesuvio] studies of water in carbon nanohorns have suggested that there is substantial proton delocalisation along the H-bond between... -
A quantitative understanding of magneto-electrical coupling in the multiferro...
The multiferroic (type II) compound, CoCr2O4 undergoes a spiral magnetic ordering and concomitant ferroelectric transition at the spiral ordering temperature (26.3 K). The... -
Looking at the motion associated with the cation and their freezing in TEA(TC...
The study of organic based materials is a popular topic and spans both chemistry and physics and presents some significant advantages. Of interest within this proposal is the... -
Vibrational properties of hydrogen in niobium oxide
Niobium oxide based compounds have superior catalytic properties. Research to get an inside into the physical properties of hydrogen is extremely difficult as hydrogen in Nb2O5... -
Competition between C-H---O hydrogen bonds and C=O----Br halogen bonds
Our main objective in this proposal is to study the competition between halogen and hydrogen bonding as a function of temperature in the complex (CH3)2C=O--- Br2. The results of...
