Modelling hair lubrication in the presence of additives

This project is sponsored by the Institute of Chemical Biology EPSRC Centre for Doctoral Training and Procter & Gamble

This is a 3-year PhD project, available for immediate start and open to Home candidates only

Supervisors:

• Professor Daniele Dini (Department of Mechanical Engineering)
• Dr James Ewen (Department of Mechanical Engineering)
• Dr Stefano Angioletti-Uberti (Department of Materials)
• Professor Nick Brooks (Department of Chemistry)

Abstract:

This project will study the molecular-level interactions and fundamental mechanisms responsible for wet friction in hair-to-hair contacts in the presence of new additives used in silicone-free conditioners and sulfate-free shampoos. Particular emphasis will be placed upon natural products with lower environmental impact. Molecular Dynamics (MD) and NonEquilibrium Molecular Dynamics (NEMD) simulations will be used to study changes on the hair surface chemistry in presence of surfactants, polymers, and natural products and their impact on hair-hair lubrication. We will also explore the use of continuum-based models and hybrid molecular-continuum simulations to capture the impact of the surface changes induced by the improved formulations on macroscale friction.

Eligibility:

The entry requirement is a degree in the physical sciences with a minimum 2.1 or above (or equivalent).

Chemistry, physics, mathematics and engineering graduates who wish to learn how to apply their physical sciences skills to biological problems. Students from biological or medicinal backgrounds are usually not eligible. If in doubt, please contact us.

We are only able to accept applications from students with ‘Home’ fee status for this project. Please see our Eligibility Criteria webpage for more detailed information.

About the ICB CDT:

Successful applicants to this project will be part of 2024 entry cohort of the Institute of Chemical Biology EPSRC CDT in Chemical Biology. The aim of the ICB CDT, one of the longest standing CDTs in the UK, is to train students in the art of multidisciplinary Chemical Biology research, giving them the exciting opportunity to develop the next generation of molecular tools and technologies for making, measuring, modelling and manipulating molecular interactions in biological systems.
