  • November 2015: A £0.5M EPSRC grant “Mapping and controlling nucleation” was awarded to Klaas Wynne and David France in the School of Chemistry. The nucleation of new phases from solution, such as the nucleation of crystals, is of immense importance to both industry and fundamental science. Industrial crystallisation has changed little in the past 350 years and suffers from an embarrassing lack of control with sometimes unexpected and severe financial consequences. The new research programme will image and control the early stages of nucleation. Driving liquid systems very far from equilibrium will allow the creation of meta- and unstable states that will give rise to nucleation and spinodal decomposition. The subsequent highly non-equilibrium processes will be controlled using a novel instrument that will change the study of crystal nucleation and will make the first steps towards control over the polymorph that crystallises. It involves laser-induced nucleation using powerful picosecond and femtosecond lasers, and programmable optics.

Applications are invited for a fully-funded 3.5-year PhD studentship at the University of Glasgow to study the chemical physics of (crystal) nucleation in the Ultrafast Chemical Physics (UCP) group in the School of Chemistry under the supervision of Prof Klaas Wynne. The PhD project involves (laser) microscopy and laser control of the early stages of nucleation in liquids. It involves laser-induced nucleation using powerful lasers and programmable diffractive optics. The new instrument will be used to carry out experiments that range from creating crystals of the desired type to shedding light on the origins of life. We are now looking for a PhD student who is interested in developing new imaging techniques including the use of spatial light modulators and interfacing a microscope with a high power pulsed laser. The ideal candidate for this position is a chemical physicist, physical chemist, or somebody with knowledge of optics or microscopy. The PhD student will be working alongside a team of postdoctoral researchers with experience in ultrafast techniques, chemical physics, and microscopy. More information and application details can be found here.
