Philadelphia, PA, September 19, 2014 --(PR.com)-- 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.
We conducted RAP experiments with an automated 4-channel instrument (RAP-id 4, Akubio Ltd) that applied the principles of quartz crystal microbalance, whereby high-frequency voltage applied to a piezoelectric crystal induced the crystal to resonate, and the resonance frequency was monitored in real time (10, 11).
