Professor Graham Smith
I am Head of the Department of Natural Sciences in the Faculty of Science and Engineering based at Thornton Science Park. Before that, I was team leader and project leader with Shell Research Ltd in the UK and with Shell International Chemicals B.V. In Amsterdam. I have also worked at the UK National Physical Laboratory and with a small scientific instrument company.

Curriculum design and validation for the B.Sc. in Physics with Materials Science.
Lectures and laboratory classes in a number of areas of physical and materials science.
My research has focused on the development and application of advanced methods of surface and materials imaging, micro-analysis and characterisation, primarily using electron beam and X-ray beam techniques. The work has included the theoretical development of the techniques, and stretching their applications into new and challenging areas.
X-ray photoelectron spectroscopy (XPS) and related methods are used to determine the composition and chemistry of surfaces and thin films, down to single molecule thickness, and to construct profiles of composition against depth within a solid specimen. We also use electron microscopy to investigate topography and element spatial distributions.
We have recently been using these techniques to study the properties of organic photovoltaic cells, to investigate the nature of deposits in diesel fuel injectors from internal combustion engines, to study surface corrosion effects after exposure to hydrocarbon liquids, to optimise the tribological properties of diamond-like carbon films for automotive applications, and to help understand environmental effects on carbon surfaces. During this work, we have developed correction procedures for hydrocarbon contamination, investigated the effect of X-ray energy on quantification of XPS data, and shown how to obtain optimal non-destructive composition depth profile data.
I am a member of the Chester Laser Engineering and Manufacturing Research Group. Follow our blog here.
