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.

EQCM Characterization of some substituted polyterthiophenes

Electrochimica 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.

EQCM study of electropolymerization and redox cycling of 3,4-polyethylenedioxythiophene

Journal of Electroanalytical Chemistry, 2001
Polyethylenedioxythiophene films were electropolymerized potentiostatically (E=1.1–1.3 V/SHE) at a gold electrode covering an EQCM from solutions containing monomer, lithium perchlorate and non-ionic surfactant (polyoxyethylene-10-laurylether). The ion exchange was studied by EQCM during redox cycling at a scan rate of 20–50 mV s−1 in 0.5 M LiClO4+0.5 ...

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 ...

Investigation of FeCO3 and FeS Precipitation Kinetics by EQCM

CORROSION 2018, 2018
Abstract Corrosion product layers play a key role in the corrosion processes by precipitating on the steel surface and can lead either to enhanced corrosion protection or, in some cases, to severe pitting, depending on the conditions. The kinetics of precipitation of corrosion product layers has a direct impact on the layers properties ...

Spotting Interface Structuring during Na‐Insertion into the NaSICON Na3V2(PO4)3 by EQCM and Operando Fiber Optic Infrared Spectroscopy

Advanced Energy Materials, 2023
Reliable operation of Na‐ion batteries requires a mastering of the interfacial processes governing intercalation kinetics. Ion desolvation, amongst others, is a crucial phenomenon as far as power applications are envisioned.

EQCM study of intercalation processes into electrodeposited MnO2 electrode in aqueous zinc-ion battery electrolyte

Journal of Alloys and Compounds, 2022
In this work manganese oxide films were obtained by electrodeposition and their electrochemical and mass transfer processes in aqueous zinc-ion battery electrolyte were studied by cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM).
