In Situ Study of Excess Lithium Metal Oxides Under Charge and Discharge
The next generations of Lithium batteries require materials with an enhanced energy density. The most realistic choice for such systems are the lithium rich electrodes (e.g.... -
Stresses in a Dissimilar Metal Weld Pipe Butt Weld
Stress corrosion cracking is an important degradation mechanism that is threatening the structural integrity of pressurised water reactors throughout the world. AREVA has... -
Magnetic ionic liquid surfactants
This proposal is to explore the magnetic properties and molecular dynamics of a new class of magnetic ionic liquid surfactants1 (MILSs) (see Fig. 1). The MILSs investigated here... -
Mixed micelles with "green" surfactants
This proposal aims to explore aqueous phase structures and compositions of a series of mixed surfactants. Although standard surfactant mixtures have been extensively studied... -
Mixing CO2-philc surfactants and hydrotropes as a new approach to control vis...
One application where liquid CO2 has found success is enhanced oil recovery (CO2-EOR) of crude oil from porous rocks. However, a significant disadvantage of using CO2 in EOR is... -
Unstressed lattice parameter studies for weld residual stress determination
This study addresses the need to improve the reliability of measurements of weld residual stress; particularly for the type of welds used within the nuclear power industry. Such... -
Residual stresses in a ring weld specimen after extended creep relaxation
Reheat cracking is a failure mechanism seen in welds fabricated from high temperature creep resistant materials. A new feature test specimen (ring-weld) has been designed to... -

Sub-micron structure of conjugated polymer interfaces
There are two contributions to the rms roughness of a polymer-polymer interface; i) the so-called ¿intrinsic interfacial width¿ due to mixing of the polymers at a molecular... -
Is there a CMC for surfactants in non-aqueous solvents?
The aim of this project is to use SANS to determine if a critical micelle concentration (CMC) exists for the formation of inverse micelles in non-polar solvents. The CMC is a... -
Studies of the mechanism of hydrotropy
The objective is to refine current understanding about the mechanism of hydrotropy with respect to polarity and electrostatic character of hydrotropes and hydrophobic solutes... -
Are magnetic excitations in the Yb based pyrochlores really gapless?
A recent neutron study of a powder sample attests a splayed ferromagnetic structure for Yb2Ti2O7. However in the same work the authors report gapless magnetic excitations even... -
