The pH at the surface of a micelle (local pH) can be markedly different (several pH units) to the bulk pH resulting in ionisable surfactants, such as CAPB being protonated while its pKa would suggest it was fully deprotonated. The aim of this PhD is to develop a computational approach to predict the pH at the micelle surface, so the correct form of ionisable surfactants can be included in subsequent calculations. This will enable new / greener / renewable surfactants and mixtures thereof to be screened in silico to determine their CMC and salt thickening potential.
The project is co-sponsored by Unilever and in close collaboration with the group of Professor Troisi in the Department of Chemistry at the University of Liverpool. The student will have the opportunity to spend time at the Unilever R&D laboratory in Port Sunlight.
The ideal candidate holds a first class or high 2.1 honours degree in chemistry, physics, chemical engineering or material science. Basic knowledge on programming is desirable but not necessary.
