Disciplines: Biomedical Engineering,Chemical & Biomolecular Engineering,Mechanical Engineering

The aim of this project is to develop an accurate theoretical framework that governs the transport of polymers in nanochannels. Applications such as lubrication in nanotribology, polymer flooding for enhanced oil recovery, and nanofluidics rely on the ability to control polymer transport at the nanoscale. However, the molecular forces and mesoscopic processes responsible for the macroscopic transport of nanoconfined polymer solutions defy current understanding. Targeting a critical capability gap, this project will develop a theoretical and multiscale computational tool for accurate prediction of the behaviour of polymers in nanoconfined systems, which will be instrumental for advancing the nanoengineering base technologies.
