To determine the temperature dependence of the structures of new mixed and ionic conducting materials in the n = 2 ruddlesden-popper,mellilite and pyrochlore systems. -
A pair distribution function study to determine the local structure of the ti...
BaTiO3 is the prototypical ferroelectic perovskite and has been well studied for over 60 years. The standard structural picture is that it is cubic and paraelectric at high... -
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... -
Neutron diffraction study of crystal structures and magnetism in PbRuO3 perov...
We have synthesised the ill characterised perovskite PbRuO3 at high pressure and temperature. Synchrotron powder x-ray diffraction shows the room temperature structure to be... -
In situ diffraction studies of the archetypal network glass, SiO2 at high pre...
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... -
Structural study of oxygen ion conduction in microporous Mayenite
The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within... -
Does tethered PEG behave as a typical polymer brush at the solid-liquid inter...
We propose to make neutron reflectivity measurements of hydrophillic polymers covalently attached, via thiol chemistry, to the gold-water interface. In particular, we will... -
4f electronic states of the filled skutterudite compound PrFe4Sb12 synthesize...
Crystals of the filled skutterudite PrFe4Sb12 with the 73~87% Pr-site filling fractions prepared under ambient pressure show some magnetic ordering around 5 K and their... -
Magnetic Properties of Rare-Earth Carbonates
We have prepared a new family of rare-earth carbonates, R4(CO3)6(H2O)2en (R=Dy-Lu). With the exception of R=Er, all materials exhibit a steadily decreasing meff below 70K. The... -
Search for Antiferromagnetic order in ZrMn2
Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type... -
Excitations, BEC, and partially ordered states of liquid 4He in disorder
We propose measurements of the elementary phonon-roton (p-r) excitations of liquid 4He confined in porous MCM-41 (45 Å pore diameter) at wave vectors Q ¿ beyond the roton¿, 2.4... -

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... -
Time reversal symmetry breaking in superconducting PrOs4Sb12 and its alloys
In 2005 we carried out muon spin relaxation (muSR) experiments in Pr(Os1-xRux)4Sb12 alloys at KEK, Tsukuba, Japan, to investigate the time-reversal symmetry breaking found in... -
Magnetic Disorder at Fe/MgO and Co/MgO Interfaces
The tunnel magnetoresistive effect (TMR) is critically dependent upon interfacial disorder. Polarised neutron reflectivity will be used to characterise the magnetic roughness at... -
The structure of hydrogen in calcium-ammonia-graphite: an in situ time resolv...
The aim of this proposal is to determine the in-plane and out-of-plane structure of H2 in the two dimensional galleries of stage-I calcium-ammonia-graphite intercalates: this... -

To determine the temperature evolution of the structures of two Bi-based perovskites with commensurate structures through their magnetic transition temperatures to contrast... -
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... -
Magnetic excitations in mesoporous hematite
We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One... -
SANS study of the structure of surfactant stabilised Pt and Ru nanoparticles
Surfactants have been used to bind and disperse Pt and Ru nanoparticles during their synthesis. In this work, we propose to use SANS to determine the thickness and packing...
