Results from a Novel Method for Corrosion Studies of Electroplated Lithium Metal Based on Measurements with an Impedance Scanning Electrochemical Quartz Crystal Microbalance

“…and the Faraday's law the calibration factor C f could be determined to (94.21 ± 0.12) Hz µg . The calibration factor C f of the gold sputtered quartz sensor, also determined by copper deposition, is 246 Hz µg −1 [9]. The theoretically calculated calibration factor C f of the aluminum foil quartz sensor was forecast to be 86.9 Hz µg -1 [61], which is very close to the experimentally determined calibration factor C f of (94.21 ± 0.12) Hz µg for 360 s).…”

“…The FIS-QCM [9] was connected with a Gamry Potentiostat Reference 600 as was previously described [25] and used in the EQCM mode [9]. The home-built EQCM cell is shown in Figure 15.…”

“…This method gives access to many parameters and processes that have to be studied for understanding ageing mechanisms. A method offering similar opportunities as AC impedance spectroscopy is the electrochemical quartz crystal microbalance (EQCM) in the form of the recently presented fast impedance scanning (FIS) quartz crystal microbalance (fis-QCM) technique [8,9]. Like AC impedance spectroscopy, it offers fast, non-destructive, in situ measurements and is therefore a method of choice in studying processes at the electrode surface [1,9].…”

QCM as Cell-Based Biosensor

“…In situ localizes a nonrigid coating, the damping behavior of the crystal is also required and can be evaluated by QCM-D (Edvardsson et al, 2006), electrical impedance (Wudy et al, 2008) and transepithelial resistance (TEER). To establish QCM cell-culture instrument, it is a useful method to monitor the interactions between the cells with the surface of a non-invasive type.…”

A novel method for in situ measurement of solubility via impedance scanning quartz crystal microbalance studies

“…The QCM is commonly used in all sectors of applied research. This technique is of great value not only in bioanalytical and life science research 6,7 but also in materials science and electrochemical research including electrochemical metal deposition, 8,9 metal corrosion studies, 10 as well as for investigations of corrosion prevention, electropolymerization of conducting polymers 11,12 and study of intercalation electrodes. 13,14 With QCM it is possible to study various processes at surfaces as well as changes in viscosity and density of the liquid at the interface.…”
