The Dynamics of Molecular Hydrogen in Synthetic Clays
In this proposal we aim to study the low temperature uptake and dynamics of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual... -
Fluorine-arsenide superconductors
A new family of FeAs superconductors have very recently (Autumn 2008) been discovered in which, rather than alternating rare earth oxide layers with FeAs layers (as for the new... -
Iron Oxide Nanoparticle Interactions with Lipid Bilayers in a Magnetic Field
Iron oxide nanoparticles are one of the first nanomaterials to be approved for use in the body. However, research into particle binding and incorporation to, as well as... -
The Structure of Ca- and Yb-ammonia Solutions: Polarons, Bipolarons and Elect...
In this experiment we propose to perform diffraction on isotopically substituted samples of Ca/Yb:ND/H3 and Ca/Yb:15ND3 at two concentrations (8 and 2 MPM) using the new NIMROD... -
Mimicking Pathogens : Floating Gram Negative Bacterial Membranes Containing t...
Recently we have been able to show two advances in the creation of realistic models of the Gram negative bacterial outer surface for use in biophysical and structural studies.... -

Structural characterisation of metal phosphates and fluorophosphates
This proposal requests neutron diffraction beamtime to study a series of novel metal fluorophosphates and acid pyrophosphates with potential as ionic conductors.... -
Antibiotic paths through the bacterial outer membrane: The strange case of va...
Gram-negative bacteria, which cause a variety of diseases including meningitis, plague, sepsis and food poisoning, are becoming increasingly antibiotic resistant. One reason is... -
muSR Investigation to probe spin fluctuations in (Y1.95-xCu0.05Cax)2Ir2O7
It is ideal to choose a non-magnetic element (Y227) in R2Ir2O7 series to investigate Ir. We have found the low-lying spin fluctuations in Nd2Ir2O7 from LF-muSR reflecting the... -
Non-destructive characterization of lunar and martian meteorites
The aim of the present work is to place the meteorites found on Earth back onto the Moon or planets from where it is assumed they come. In this context, to approach the above... -
Structural studies on complex ACu3Ti4O12-type perovskites.
Abstract. We request one day of beamtime on POLARIS to collect Neutron Diffraction (ND) data from a variety of ACu3Ti4O12-type perovskite-related compounds that exhibit higher... -
Organization of mitochondrial membranes upon oxidative stress: Impact on apop...
Mitochondria are not only the powerhouse of the cell, but are also involved in cellular suicide via apoptosis (programmed cell death). The mitochondrial apoptotic pathway is a... -
High-pressure neutron diffraction studies of valence transitions in ACu3Fe4O12
Two new A-site ordered perovskite structure oxides, CaCu3Fe4O12 and LaCu3Fe4O12, were recently synthesized under high-pressure and high-temperature conditions in Kyoto. These... -
Kinetics of surfactant multilayer formation / dissolution at interfaces
The spontaneous formation of multilayer structures at surfaces and interfaces from self-assembly in mixed surfactant and in polymer / surfactant mixtures are being increasingly... -
Cellulose-based polyelectrolytes for microencapsulation: conformational trans...
Addition of multivalent salts to water soluble polyelectrolytes, such as sodium carboxymethyl cellulose (NaCMC), induces conformational change to the polyelectrolyte structure,... -
Visualisation of Multi-component Ion Exchange for Oil Recovery
Release of oil bound to clay minerals by exchange of bridging cations for non-bridging ones is postulated as a major mechanism for enhanced oil recovery. In this work we propose... -
Disrupting structural correlations in the Na-Ca-NH3 system
Na or Ca, when dissolved in ammonia, yield metallic liquids. These liquids are fully miscible and yet each possesses a different intermediate-range order depending on the parent... -
A complex model of the bacterial outer membrane containing oriented proteins ...
The Outer Membrane (OM) is found in bacteria which cause plague, cholera & Legionnaire?s disease. It is important as; a barrier to antibiotics & the site of... -
Floating Bilayer Mimics of the Gram Negative Bacterial Outer Membrane
The gram-negative bacterial membrane is of extreme medical importance. The two main lipid components of the outer membrane are lipopolysaccharides (LPS's) and DOPE. We will... -
Ca-ions at PS-containing biomimetic lipid layers: Interfacial water
Lipid membranes provide a sensitive platform for a variety of biological functions, and membrane lipid distributions are carefully regulated. In this project we plan to study...
