Electrochemical quartz crystal microbalance studies of redox polymer films

Macromolecular Symposia, 1994
AbstractElectrochemical quartz crystal microbalance measurements are reported for redox switching of thin films of three macromolecule‐metal complexes: poly(vinylferrocene) (PVF), 10% osmium‐functionalized poly(vinylpyridine) (Os‐PVP), and 10% osmium functionalized poly(vinylpyridine‐co‐styrene) (Os‐PVP‐co‐PS). The data provide insight into the ion and

Electrochemical quartz crystal microbalance study of magnesium porphine electropolymerization process

Journal of Solid State Electrochemistry, 2020
Material and charge balances in the course of the electropolymerization process of the non-substituted Mg(II) porphine (MgP) at a low oxidation potential from its acetonitrile solutions of various concentrations have been studied via the in situ electrochemical quartz crystal microbalance method (EQCM).

ELECTROCHEMICAL QUARTZ CRYSTAL MICROBALANCE STUDY OF THE ELECTRODEPOSITION OF PLATINUM

Electrochimica Acta, 2015
Abstract The electrodeposition of Pt from aqueous solutions of K 2 PtCl 4 (Pt(II)), H 2 PtCl 6 (Pt(IV)), and a mixture of Pt(II) and Pt(IV) was studied using the electrochemical quartz crystal microbalance (EQCM) method. Pt deposition and cathode current flow began at the same potential in the Pt(II) solution.

Quartz crystal microbalance characterization of electrochemical doping of polyaniline films

Synthetic Metals, 1993
The electrochemical ionic exchange of polyaniline film-coated electrodes was studied in detail by electrogravimetry using an electrochemical quartz crystal microbalance. The influence of film thickness, electrolyte composition and potential sweep rate is discussed.

Electrochemical quartz crystal microbalance studies of partially oxidized tetracyanoplatinum salts

Journal of Materials Chemistry, 1996
The electrochemical quartz crystal microbalance (EQCM) has been used to study electrocrystallization and dissolution of the partially oxidized cyanoplatinum complexes K1.75Pt(CN)4(H2O)1.5 and K2Pt(CN)4Cl0.3(H2O)3. Electrocrystallization from aqueous solutions of K2Pt(CN)4 was found to proceed with low efficiency (5–20%) by progressive nucleation and ...

Investigation of cobalt deposition using the electrochemical quartz crystal microbalance

Electrochimica Acta, 2006
Electrodeposition of cobalt from sulfate solutions at different pH values was investigated using the EQCM technique coupled with cyclic voltammetry. The results show that cobalt hydroxide is formed simultaneously with cobalt deposition during the early stages of reduction due to the pH variation near the electrode surface caused by the parallel ...

Calibration of an Electrochemical Quartz Crystal Microbalance during Localized Corrosion

Journal of The Electrochemical Society, 1994
An electrochemical quartz crystal microbalance (EQCM) was calibrated during the course of the self‐propagating dissolution of a Ni‐Cu film initiated by a laser pulse focused on a 0.1 mm spot. The initial spot spread over the surface in a well‐defined circular form.

Performances and Limits of a Parallel Oscillator for Electrochemical Quartz Crystal Microbalances

Analytical Chemistry, 2002
This paper describes a driving circuit for an electrochemical quartz crystal microbalance (EQCM) adapted to a wide range of applications. The oscillator is a Miller-type parallel oscillator using an operational transconductance amplifier (OTA). A theoretical study of the oscillating circuit led to the analytical expression of the microbalance frequency
