The research interests of the Mills group are wide and varied including: dye and semiconductor photochemistry, redox catalysis (in particular, oxygen catalysis), solar energy conversion (in particular artificial photosynthesis) and colour and fluorescence based indicators and smart inks and plastic films.

UV dosimetry for SODIS

Mills group member Katherine Lawrie visited a research group at the University of Cadiz, Spain, as part of a collaboration aimed at creating a colourimetric UV dosimeter for solar water disinfection (SODIS). We want to develop a device which tells users of the SODIS method (typically those in third world countries) when a bottle has been exposed to sufficient amounts of sunshine and the water is safe for drinking.
