[School of Natural Sciences PhD Scholarships] Exploring the polarizability of water and other liquids near surfaces and under molecular-scale confinement

About the project

About the Project A PhD position is available in our research group to investigate a fundamental physical property of water and other molecular liquids — polarizability — near biological or non-biological interfaces and under nanoscale confinement. Many natural and technological processes, from molecular organisation and chemical reactions to molecular transport, biological function, and energy storage and conversion, are governed by the dielectric response of liquids, particularly water and electrolyte solutions. Near biological or non-biological interfaces, or within nanoscale cavities, water molecules and ions reorganise over nanometre and sub-nanometre length scales, and their polarization properties can differ markedly from those in the bulk [1,2]. Despite their importance, these properties remain poorly understood because probing liquids within only a few molecular layers of an interface or under nanoconfinement is a major experimental challenge. Our group has developed Atomic Force Microscopy (AFM)-based electrical techniques to probe these properties directly at the nanoscale [3,4], including approaches combined with advanced two-dimensional (2D) material technologies [5–7]. These approaches enable the study of liquids in well-controlled environments ranging from 2D channels and nanopores to biological interfaces. The project will use and further develop these methods to investigate the dielectric response of liquids at molecular scales. Experimental systems may include nanoscale and atomic-scale channels and pores, solid-liquid interfaces, or biological interfaces, depending on the student’s interest and background. The research may involve AFM-based nanoscale electrical measurements, experimental and method development, fabrication and characterisation of 2D heterostructures, preparation and characterisation of biological samples, quantitative data analysis and physical modelling, and the development of computational tools using Python and/or MATLAB. The student will gain experience with state-of-the-art experimental techniques and contribute to developing new approaches for exploring fundamental physical property on the molecular scale that remain inaccessible to standard macroscale techniques.
