The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly is an important structural signature associated with a wide range of technological...

Li-enriched layered transition metal cathode materials are attracting long-standing interest since they exhibit energy densities and capacities significantly higher than the...

NiMH batteries exhibit a hysteresis, or path dependence, regarding the rest voltage of the system. Depending on charge/discharge history of the battery the rest voltage will be...

We request 3 days’ beam time on POLARIS for in-situ powder diffraction studies of the reactions of lithium amide or lithium imide with manganese(IV) oxide under flowing argon or...

With the biobased economy growing substantially and pressure to reduce reliance on palm and crude oil derived materials, it is vital that the Home and Personal Care industry...

The Bragg edge transmission technique (BET) is a diffraction method exploiting the edges appearing in the transmitted neutron spectra crossing polycrystalline materials and is...

Silicate spinels are important minerals in the transition zone region of the Earth and in order to understand seismic signals from these depths (550-660 km) we need to know the...

Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al...

Ammonia is seen as a key part of the transition to a sustainable energy economy, but needs decomposition catalysts to release its stored hydrogen. Lithium nitride-hydride...

We have constructed a novel microwave frequency resonator that can sit within the GEM and POLARIS diffractometers and will allow us to simultaneously collect diffraction and...

The formation of multilayer structures at surfaces and interfaces from self-assembly in mixed surfactant and in polymer / surfactant mixtures has been recently reported, and...

YbNiSn is an Ising ferromagnet with non-colinear spins that undergoes a first order magnetic transition in low magnetic field (0.9 T). The transition is associated with strong...

We seek to develop new MOFs for sensing and removal of toxic gases (e.g., SO2) and request 4 days on POLARIS to study the structural binding details and dielectric data...

Polymers and surfactants are key components in detergency. Understanding their interactions is essential to formulate smartly. Detergent formulations usually contain a mixture...

Glass Ionomer Cements (GICs) have found numerous applications as bone fillers, replacements and adhesives, particularly in dentistry due to their tooth like appearance and...

We are examining various perovskite solid solutions based on NaNbO3 or BiFeO3 that havepromising ferroelectric or multiferroic properties. All of these solid solutions show...

LaSrCoFeO6 is a rhombohedral perovskite, and can be reduced to the orthorhombic brownmillerite LaSrCoFeO5 in reducing atmospheres at around 600 deg C. This material is air...

Silica glass is one of the most widely studies amorphous materials. It is the archetypal glass former, comprising a network of corner-shared SiO4 tetrahedra. Recently a lot of...

In this proposal we aim to study low temperature structure of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual motivations for this...

We plan to study the temperature dependence of magnetic excitations in the optimally doped high-Tc superconductor Bi$2$Sr$_2$CaCu$_2$O${8+\delta}$ (BSCCO). We have previously...
