Research projects and opportunities with
Dr Stephen H. Ashworth
Phthaolcyanines have been shown to be active against cancer cells in
photodynamic therapy. Professor Mike Cook has a research group which
routinely synthesises new phtalocyanine molecules. I collaborate with
Prof. Cook to investigate the photophysics of his new products in
order to find the best candidates for photodynamic therapy, optical limiting and sensor
applications.
Atmospheric iodine chemistry
We have recently observed the absorption spectrum of the OIO
radical using cavity ring-down spectroscopy. A combination of
measurement and modelling is being used to determine the role
OIO and other iodine oxides play in forming aerosol particles
in the atmosphere.
A Fourier Transform Microwave
spectrometer in order to measure the rotational spectra of
higher iodine oxides. This will not only enable us to
distinguish between the various species but also measure
their dipole moments: a measurement which is crucial for
modelling the condensation and aggregation of these species
as they form aerosols.
Spectroscopy of gas phase metal species.
Gas phase metal species have been shown to have flame suppresant
properties and evironmentally benign by-products. We have the
facilities to study the spectra in order to learn about the geometric
and electronic structure of these low vapour pressure species.
