This proposal is part of a research programme which is focused on nano-fibres prepared by electrospinning. The programme is centered on developing an understanding of the...

We propose to use OSIRIS to investigate the changes in magnetic ordering which occur when a series of layered oxysulfides with mixed-valent Mn ions in their oxide layers are...

The organic-inorganic perovskites (CH3NH3Pb(Br,Cl,I)3) have been identified as efficient photovoltaic materials. Theoretical calculations have suggested that the low energy...

We request 8 days on IRIS to study the diffusion of adsorbed H2 gas and C2-hydrocarbons molecules within a gated indium-based porous metal-organic framework (MOF) as a function...

Zeolites are porous materials that can absorb other molecules, which makes them useful in a number of fields. When they absorb molecules, they change size, either shrinking or...

This proposal aims to probe the quadrupolar order believed to exist in the heavy fermion compound Ce3Pd20Si6 (CPS). Two phase transitions have been uncovered (in zero applied...

Increasing the density of hydrogen storage is critical for the commercial introduction of hydrogen vehicles. Our nanostructured electrospun ammonia borane (AB)-polystyrene (PS)...

The hepta-nuclear Fe(III) title compound Fe7 exhibits a unique antiferromagnetic exchange topology reminiscent of a three-bladed propeller, giving rise to spin frustration, also...

The orientation of spins in a natural sample of Ti-bearing hematite (Fe2O3) has been measured previously from 2-300K using neutron powder diffraction. It was shown that spins...

The high voltage and energy density has made lithium-ion batteries ubiquitous in portable electronics, such as iPods, laptops and mobile phones. At present, they are typically...

This proposal aims to exploit the high resolution of HRPD and OSIRIS to probe the structures of the solid solution Ba2CoO2Cu2(Te1-xSex)2. The compound Ba2CoO2Cu2Te2 shows...

In this proposal we would like to study the dynamics of interlayer species in hydrotalcite clay: (a) water and (b) terephthalate anions. In the case of water, the aim is to...

We propose to conduct inelastic neutron scattering (INS) measurements on deuterated polycrystalline samples of the magnetic molecule {Mo214V30}, to determine the low-lying...

YbAgGe has an enhanced electronic specific heat coefficient and two magnetic phase transitions at TM1=0.8K and TM2=0.65K. We have grown a series of TbxYb1-xAgGe and YbAgGe...

We propose to use OSIRIS to determine the magnetic structures of a series of cobalt oxysulfides containing Co in square planar coordination. Several compositions...

We request 4 days on IRIS to study the temperature dependance of the structural dynamics in amorphous sodium-ammonia (Na-NH3). This will be the first investigation of the...

This proposal regards studies of the structure and morphology of polymer electrolytes which can be used in Li-batteries. These electrolytes are effectively used in electric...

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...

We will use the high resolution of HRPD and the excellent long d-spacing data available on OSIRIS to investigate the phase transitions in Sr1-xNaxFe2As2 which are associated...

Affordable large-scale energy storage systems with improved capacity are crucial to a sustainable energy future, and the great availability of Na in sea water makes Na-ion...
