High pressure behaviour of ammonium carbamate
A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound... -
Spontaneous surface multilayer formation in oligoamine ¿ surfactant mixtures
This proposal is part of a major EPSRC (EP/GR065705)/Unilever funded programme to develop and control the spontaneous formation of surfactant multilayer structures at... -
Quantum and thermal critical scaling in XY-dipolar antiferromagnet LiErF4
We have established the material LiErF4 as a dipolar antiferromagnet with planar anisotropy, exhibiting both classical and quantum phase transitions. Where, thermal transition... -
Magnetic ordering in the new Multiferroic compounds Sm1-xYxMnO3
In order to understand the emergence of multiferroic behaviour in the RMnO3 type compounds, it is neccessary to understand the relationship between structural parameters such as... -
Neutron Diffraction Studies of Polycrystalline CeCr1-xTixGe3 (x = 0, 0.5, 1.0)
Observation of both ferromagnetic ordering and Kondo/heavy fermion behavior in a system is not so common. Recently we have discovered the Kondo effect/heavy fermion behavior in... -
How perfume structure affects surface coadsorption with anionic surfactants
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... -
