EQCM Characterization of some substituted polyterthiophenes

open access: yesElectrochimica Acta, 1999
Abstract The electrochemical growth of polyalkylterthiophenes has been monitored in situ with the Electrochemical Quartz Crystal Microbalance (EQCM). Potential controlled synthesis of poly-3′4′-didodecyilterthiophene (3′4′-DDTT) and poly-33″-DDTT revealed an unexpected cathodic precipitation following the anodic deposition.

Investigation of precipitation kinetics of FeCO3 by EQCM

Corrosion Science, 2018
Abstract Iron carbonate (FeCO3) is the most common corrosion product in aqueous CO2 corrosion of mild steel. When it forms, the FeCO3 corrosion product layer may be protective, by serving as a diffusion barrier and by affecting the rate of electrochemical reactions at the surface.

An Instrument for Simultaneous EQCM Impedance and SECM Measurements

open access: yesAnalytical Chemistry, 1999
A novel combination of an electrochemical quartz crystal microbalance (EQCM) and a scanning electrochemical microscope (SECM) has been built. Unlike conventional EQCMs, the instrument described here allows rapid in situ measurement of the modulus of the quartz crystal's transfer function. Data analysis in the complex plane for the Butterworth-Van Dyke (

An EQCM study of the oxidative deposition of alkylthiolates on gold

Journal of Electroanalytical Chemistry, 2001
The oxidative deposition of alkylthiolates on a gold surface has been studied with the electrochemical quartz crystal microbalance (EQCM) method. The surface concentration of alkylthiolates calculated from the oxidative charge and from the EQCM signal using the Sauerbrey equation are in excellent agreement for depositions done in 0.1 M KOH and 0.1 M ...

Study of adsorption of citrate on Pt by CV and EQCM

Electrochimica Acta, 2008
Abstract Citrates are frequently used as additives in the electrodeposition of metals such as manganese in order to improve deposit characteristics and process efficiency. Nevertheless, few studies have been reported on the mechanism of citrate adsorption.
