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...

We will investigate the structure of 4-chloroimidazole a material which undergoes extreme anisotropic thermal expansion. This is believed from our initial X-ray data to be due...

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 will explore the effect of elevated pressure on the widely used civil and military explosive TNT (trinitrotoluene). We are proposing a careful high-pressure...

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 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...

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...

Catalysis is defined as the increase of the rate of the reaction or directing the reaction to one of the thermodynamically permitted pathways that lead to different products. It...

Ionic liquids are of interest to chemistry and material sciences because of their designer properties. The protic ionic liquids are excellent proton carriers in fuel cell...

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...

This is part of a larger experiment which will investigate three related systems which contain copper deficient anti-fluorite-type copper sulfide layers. The overall aim is to...

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...

Water is important in many scientific and technological areas, yet our understanding of this remarkable liquid remains very incomplete. In may cases, it is the properties of...
