The project entitled “Application of the combined electrochemical quartz crystal microbalance and probe beam deflection technique in deep eutectic solvents” uses the EQCM/PBD method for the first time applying to metal deposition/dissolution processes in deep eutectic solvents. Collaborators on this project include: A. Robert Hillman, Karl S. Ryder, Christopher J. Zaleski, Virginia Ferreira, Christopher A. Beasley, and Eric Vieil.
