Structure and stoichiometry in new nitride catalysts; anion mobility, chemica...
Our studies focus on the use of Co3Mo3N (331) as a catalyst in ammonia synthesis. During synthesis, N is lost and the compound is transformed to the new nitride Co6Mo6N (661); a... -
Nanostructure definition in electrospun fibres of polymer blends
This proposal is part of a research programme which is focused on nano-fibres prepared by electrospinning. The programme is centered on the spinning... -
The impact of synthetic perfumes on surfactant self-assembly.
This proposal is part of a broad collaboration between Oxford, CCLRC, and Unilever in the study of surfactants and mixed surfactants at interfaces and in solution. This is an... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
Crystallographic and Magnetic structures of PrMn7O12
The study of novel manganites, where the tailoring of the Mn formal valence state on the B site is done by the ordering of different cations on the A site of the ABO3 (B:Mn)... -
Revising the onset of anharmonicity in proteins
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... -
Effect of drug on the micelles formed by ionic surfactants
The aim of the study is to use SANS in combination with contrast variation to determine the effect of solubilising the lipophilic drug, testosterone propionate, in micelles... -
RF-mSR study of high-Ge Si1-xGex alloys
Single crystal, bulk Si1-xGex alloys are available across the alloy composition range, and provide opportunity for study of alloy properties in transition between the two... -
Towards an improved understanding of the active phase of iron based Fischer-T...
The applicants have recently completed a series of INS studies on a model iron Fischer-Tropsch catalyst. That work established that different sample pre-treatments could... -
RF μSR in the gas phase: understanding a ¿null¿ result
We have made a significant effort to develop Radio Frequency μSR (RF μSR) as a technique for spectroscopy of organic radicals in the gas phase. Realising this method... -
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... -
The Interaction of Ammonia with Binary and Ternary Deuterides;
The interaction of ammonia with binary hydrides (prototypically, the interaction of LiH with ammonia gas) is thought to be the predominant interaction for hydrogen production... -
Nature of the protein corona on nanoparticle surfaces
When nanoparticles enter a biosytem they rapidly acquire a protein corona. The nature of the outer part of this corona will determine the response of the biosystem to the... -
The effect of combined modifiers: understanding the interactions between alka...
The mixed alkali effect is a well-known phenomenon whereby combining two alkalis in a ternary glass system can produce physical properties which can be superior to, but cannot... -
Effect of pH on the shape of oil-in-water microemulsions formed by a zwitteri...
Despite interest in microemulsions as drug delivery vehicles, there is a lack of structural understanding to justify the formulations used. The present study examines the use of... -
Microscopic structure of acetic acid in water and methanol
Some of the most important chemical reactions involve Brønsted acids and bases where the solvation structure and transport dynamics of charged defects in hydrogen-bonded... -
Self-assembly in biosurfactants and biosurfactant / surfactant mixtures
This proposal is part of a new project which is a collaboration between Oxford, Newcastle, Ulster, and Unilever on the development of sustainable laundry detergents, using... -
The effect of particles on the structure of mucin ¿ understanding the challen...
Progress in the development of nano-sized hybrid therapeutics and nano-sized drug delivery systems - "nanomedicines" - over the last decade has been remarkable. One key... -
Szilard-Chalmers reaction: towards understanding of breaking of chemical bond...
When a nucleus captures a low energy neutron it emits a gamma ray as it recoils. The recoil energy is often sufficient to break a covalent bond to the atom concerned. The effect... -
Towards an accurate structural phase diagram for the novel BiScO3-PbTiO3 ferr...
The aim of this experiment is to determine accurately the crystal structures of phases in the (1-x)BiScO3-xPbTiO3 (BST-PT) perovskite phase diagram, particularly in the vicinity...
