Professor Styliani Constas Delivers Plenary Talk at FOMMS
Prof. S. Constas delivered a plenary talk at FOMMS (Foundation of Molecular Modeling and Simulation) Conference on July 20, 2022 at Delavan, Wisconsin. This is the first participation from Western at this prestigious conference. The talk was entitled "Chemistry in Small Volumes: Bridging Electrostatic Properties between Nanoscopic and Microscopic Droplets". It presented how the simulations allowed to unravel the mechanism of electrospray ionization mass spectrometry starting from the microscale droplets up to nanoscale. In the presentation, the star-shaped droplets, the electrostatic confinement effect and the chain extrusion mechanisms discovered in the Consta lab were discussed.
