We propose to study the temperature evolution of the spontaneous strain, crystal and magnetic structure of the charge ordered, mixed valence iron silicate ilvaite. In addition,...

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...

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...

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...

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...

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...

Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crysta. There are outstanding...

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

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...

In the late 1960s, a molecular theory of sweet taste was proposed, based on the presence of a ?functional structure? in all sweeteners, eliciting the sweet response via the...

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...

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...

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 seachs time to establish the conditions under which electrospinning can be used to provide (non-equilibrium) mixtures of immiscible polymers. Such an outcome might...

Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crystal. There have been no...

Block copolymers are of interest due to their ability to undergo microphase separation. Originally block copolymers were produced with a low polydispersity index (PDI) as they...

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...
