Tunneling effect of hydrogen and deuterium in alpha-Mn
DINS is capable of observing coherent tunneling of protons in a double well potential through the effects of the tunneling on the momentum distribution of the protons. In our... -
Temperature induced structural phase transitions in BaPrO3 and acceptor doped...
The sequence of structural phase transitions that occur in distorted ABO3 perovskites as a function of temperature is of intrinsic interest for better understanding of the... -
Search for Neutron Spin Resonance and High Energy Spin Excitations in Exotic ...
Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,... -
Test of a New Supercritical In-Situ Hydrothermal Cell
The objectives of this proposal is to seek 2 days on POLARIS in order to test and complete a full commissioning of the latest design of our prototype in-situ reaction cell for... -
Stroboscopic Neutron and X-ray mapping of strain fields in dynamically loaded...
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... -
Investigating the formation of novel mixed amide-imide complexes and understa...
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... -
Biskyrmion Magnetic Nanodomains in the MnNiGa single-crystalline Study by Sma...
Magnetic skyrmions are topological vortex-like spin objects that were recently discovered in bulk chiral magnetic materials. Several months ago we discovered super stable... -
The chemisorption of hydrogen over a high surface area cobalt catalyst: An IN...
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... -
Structural determination of non-stoichiomentric phases Li2+yND for 0<y<1
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... -
Structures of metastable water ice XVII with different guests molecules
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... -
Micelle structures in unequal mixtures of amino-acid surfactants
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... -
In-situ studies of alkaline earth nitride deuterides
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... -
Gas-phase oxidation of insoluble monolayer at air-water interface with no equ...
The Earth¿s climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects cloud droplet size and optical properties, important climatic... -
Towards the development of lithium manganese nitride as novel two stage regen...
In the last decades the production and consumption of reactive nitrogen increased exponentially due to the extensive utilisation of nitrogen containing compounds as fertilizers... -

This proposal seeks to test a new battery designed to allow in situ neutron diffraction measurements of lithium ion battery electrodes under charge and discharge. We have... -
In situ studies of mixed-phase oxygen transport membranes
The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen... -
In-situ high resolution neutron diffraction studies of cemented carbides
Cemented carbides are composite materials manufactured via powder metallurgy. The excellent wear resistance, high hardness, and high toughness make them widely used materials in... -
High-pressure, high-temperature studies of energetic materials - RDX and HMX
One of the aims of this proposal is to quench to ambient pressure a metastable form of the widely used secondary explosive RDX. This is formed above ~4.5 GPa and 448 K but is... -
The high temperature high pressure behaviour of ammonia hydrates
Ammonia hydrates are important constituents of the outer solar system. In recent x-ray studies we have found evidence for a solid solution between ice and ammonia at high... -
Time Resolved Studies on Inorganic Film Formation at the Air-Solution Interface
In a recent SURF experiment on the formation of silica films templated with cat-anionic/polymer complexes we found that the film growth and evolution occurs on a faster time...
