Molecules at interfaces
Molecules at surfaces have a rich set of behaviours and are the fundamental basis for colloidal stability and functionalisation from large scale industrial processes to consumer products and from paint to smart drug delivery vehicles.
My principal interests lie in understanding and manipulating the behaviour of polymers in solution and the interactions of polymers, surfactants and nanoparticles. There is a particular focus on developing physical models to represent these systems to permit more general understanding to be developed. Surrounding this basic theme is a diverse set of collaborative projects that I have undertaken.
The characterisation of molecules at surfaces brings many challenges. Understanding the ensemble or molecules, what averages are useful in characterising the ensemble and how to design experiments to tease more information out of the ensemble all provide a lot of entertainment.
Stuart undertook his PhD research into the kinetics of RAFT-mediated living polymerisations jointly between the CSIRO, the Cooperative Research Centre for Polymers and the Key Centre for Polymer Colloids. Following two years' post-doctoral research at the University of Melbourne, he moved to Bristol to take up a Marie Curie Individual Fellowship. He was appointed to the position of Lecturer in Polymer Chemistry in 2009.
Scattering phenomena with applications in colloid science
Scattering is one of the most common of physical phenomena that we observe in everyday life. It determines the colour of the sky and the optical properties of many solutions. In chemistry and physics the scattering of X-rays and neutrons can be used to measure the size and shape of macromolecules and colloidal suspensions. The longer wavelengths of microwaves can be used to observe rain, snow and the scattering of ’starlight’ can be used to investigate interstellar dust. The basic phenomena of scattering occurs when the wavelength of the radiation is on-a-par with the size of the scattering entity. We can also observe scattering with sound waves and measure objects the size of golf balls.
