Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical...

In a previous proposal we started to study the micellar structures formed from biodegradable surfactants synthesised using amino acids as the headgroups. The aim of this work is...

Very recently, we have studied the crystalline structure of the C0-phase H2-filled ice (recovered at room pressure and low temperature) and ice XVII, a new form of ice...

In a series of in situ neutron diffraction measurements from deuterium up-take in Li3N, the present authors have identified a novel non-stoichiometric 'quasi-imide' of...

In a recent EPSRC / Unilever / Oxford CASE project we have used NR to explore and develop optimised delivery mechanism for active benefit agents such as perfumes. In particular...

Frustration occurs in materials where antiferromagnetic (spin up and spin down pairs) are incomparible with the underlying crystal morphology, for example where the connectivity...

Zirconia-ceria ceramics are promising materials within automotive exhaust catalysts, exploiting the Ce3+<->Ce4+ redox reactions to store oxygen. For a Zr:Ce ratio of 1:1...

Migration and surface segregation of low molecular weight oligomers in adhesive formulations is a poorly understood, but hugely important phenomenon, responsible for most of the...

In collaboration with Sasol Technology UK Ltd, the research team have previously used INS to investigate the surface chemistry of synthesis gas (CO + H2) over a series of...

Inexpensive light-metal amides are among the most highly active and effective ammonia decomposition catalysts at modest temperatures and are likely to surpass the performance of...

The aim of the experiment is to monitor the temporal evolution of gamma prime precipitates in three polycrystalline nickel base superalloys using Sans2D. This instrument is...

Bearings are essential components in many types of machinery, working to reduce energy losses. Over the last century improved analytical models were developed for predicting the...

Many geological processes are governed by the migration of hot, mineral-rich water. These "hydrothermal" fluids are stable at high pressures and temperatures and are important...

The Ruddlesden-Popper (RP) compounds An+1BnO3n+1 exhibit a broad range of technologically interesting properties such as high-Tc superconductivity, colossal magnetoresistance,...

Hydrogen abstraction reactions are key steps in free radical mechanisms that dominate the combustion and atmospheric chemistry of the alkane hydrocarbons and, as such, merit...

This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages,...

A family of sterol-modified glycerophospholipids (SML) have been synthesized in which the sn-1 or sn-2 position is covalently attached to cholesterol and the alternative...

Our group has been working partially oxidized cellulose nanofibrils which form gels in aqueous formulations. Recently we have observed that these fibrils also gel when dialysed...

Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the...

Modulation occurs when there is ordering on two (or more) length scales. When the ratio of these is an integer, the modulation is said to be commensurate, i.e. one ordering is...
