Welcome to the Wong Group
The structure and dynamics of complex fluids are strongly affected by the stress, temperatures and degree of confinement. We apply fluorescence spectroscopy and imaging to polymers and complex fluids under extreme conditions.
We are particular interested in phase stabilities, and phase transitions of bulk fluids and confined fluids at high stress and high temperature conditions. One of such complex fluids in extreme condition is lubricant in a tribological contact. Our work allows various information such as lubricant structures and viscosity, phase transition, aggregation, adsorption, and self-assembly of additives, lubricant flow to be obtained. When combined with mechanical testing snd film thickness measurements, the molecular origins of mechanical responses of lubricated system is established.
PhD opportunities for computation of polymeric additive/complex fluids
PhD opportunity on smart additives, funded by EPSRC and the industry.
This PhD focuses on smart additives for lubricants. Additives can modify the properties of a lubricant to extend its temperature range, or to improve its friction properties. A particular class of additives are viscosity modifiers. Viscosity modifiers are usually polymers and their chemistry and architecture can be tailored to specific needs. It is believed that polymeric viscosity modifiers operate through changes in chain conformation but fundamental understanding of their mechanism of operation is lacking.
This project will use computer simulations to investigate the effect of polymer molecular architecture on its response to temperature, pressure and high shear conditions, with strong relevance to lubrication applications. You would be part of the Tribology Group at Imperial College London, one of the largest academic group working on tribology research in the world, with multiscale experimental and computational capabilities. You will work closely with experimentalist working on related projects and with other computational researchers. You would also interact with our industrial sponsor.
The successful candidate should be a UK/EU student matching the EPSRC definition of a home student. S/he will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London, majoring in Physics, Chemistry or Engineering. S/he should be strong with Math, enjoy coding, good with details and curious about how and why things work. S/he should be a good communicator and a good team player, comfortable in a culturally diverse work environment.
