Mechanisms and applications of collisions at liquid surfaces


Project Description

You will study the dynamics of scattering at the gas-liquid interface. You will improve fundamental understanding of mechanisms of collisions at atmospherically relevant surfaces and explore the exploitation of this insight through new methods to probe the surfaces of technologically interesting materials.

The gas-liquid interface plays a crucial role in many diverse chemical environments, including evaporation, respiration, gas capture and storage, and multiphase catalysis. In the atmosphere, crucial reactions take place at the surfaces of aerosol particles. Nevertheless, despite its practical importance, this interface remains one of the least well explored. You will carry out experiments on the dynamics of gas-liquid interfacial collisions with the aim of improving the understanding of the mechanisms of reactive and inelastic collisions. The systems chosen will include processes directly relevant to atmospheric aerosol chemistry, including measurements of OH scattering at representative organic liquid surfaces. The methodologies you will help to develop include novel applications of real-space imaging of the inelastically scattered OH; and frequency-modulated infrared probing of the reactive product H2O. In a parallel, related strand of research, you will help to exploit this mechanistic understanding by developing new methods to probe the surface structures of technologically interesting materials. Building on our recent successful proof of principle, you will aim to extend the range of projectiles for the RAS (reactive-atom scattering) method to detect new chemical functionalities at the outer layers of ionic liquids.
