High Temperature Surfactancy for Cleanliness in Modern Engines

Project Description

Industry-funded PhD in Colloid and Interface Science in the School of Chemistry, University of Bristol

The aim of the PhD is to study self-assembly of surfactants in non-aqueous solvents under extreme conditions, especially high temperatures as are experienced in modern efficient internal combustion engines. The programme builds on the extensive experience at Bristol in colloid and interface science and developing surfactant systems with tailored self-assembly. Families of model surfactants with systematic variations in structure will be utilised and the self-assembly studied in non-aqueous solvents. Phase behaviour studies, interfacial tensiometry and small-angle neutron scattering and neutron reflection at both Rutherford Appleton Laboratories (Didcot, UK and Institute Laue Langevin (Grenoble, France will be utilised. Other facilities external to Bristol will be used at Infineum (Abingdon, UK).

Specifically this PhD will investigate solution phase behaviour (and associated surfactant degradation) of surfactants in non-aqueous media, and also seek to understand the mechanism(s) of surfactant adsorption and removal of predominately carbonaceous deposits on hot metal surfaces.

This PhD links strongly with other Infineum PhD programmes: experimental tribometery and neutron reflection (Cambridge, Bristol), computer simulation (Edinburgh) and model polymer synthesis (Warwick), and cross-university collaborations will be developed.

Interested and suitably qualified candidates should make informal contact at with Professor Julian Eastoe ( before Friday 29 March 2019. The intended start date for the project is 23 Sept 2019. After contacting Professor Eastoe, you may then apply using the University of Bristol on-line application system.

Funding Notes

Successful applicants will receive a fully funded scholarship (Fees, stipend and consumables) provided by Infinium
