Previous projects in which I have been involved have varied from visualisation of various excited-state orbitals of hydrogen atoms to classical cryptography. The material here includes serious academic research as well as undergraduate assignments.

Current Projects

Making "stable" emulsions Emulsions can be prepared by microfluidics that are stable on the lab bench for years. With a bit of extra chemistry, can they also be made stable to heating and mechanical agitation? more »

Miniature NMR instrumentation Solvent relaxation NMR with custom, miniaturised instrumentation to look at the surface chemistry and structure of near-surface layers. more »

Surface structures of polymer solutions in confined geometries Measurements of the inter-surface and near surface structures of polymer gels under compressive forces have been made using a new neutron compression cell. more »

Light scattering of non-spherical particles Light scattering cross-sections are calculated numerically for a variety of nanoparticles using the Discrete Dipole Approximation. more »

Bumblebee instrument management system Instruments and equipment are booked and shared between users through a free, web-based management system. more »
