Liquid Jet Photoelectron Spectroscopy

Liquid jet photoelectron spectroscopy has been used in the past to investigate solvation of small molecules, nanoparticles, and dynamics at the liquid-vapour interface. By coupling this technique to a microfluidic chip, we will take advantage of the mixing that occurs to characterize metastable solutions related to nanoparticle formation, carbon capture, and atmospheric chemistry with near ambient pressure liquid jet photoelectron spectroscopy. These experiments will be carried out both in a lab-based setting and at synchrotrons across the world.
