Electrochemical quartz crystal microbalance study of electrodeposited ruthenium

Journal of Electroanalytical Chemistry, 1999
Voltammetric and electrochemical quartz crystal microbalance measurements have been used in the characterization of surface electrochemical processes of electrodeposited ruthenium under the conditions of repetitive potential cycling in 0.5 M sulphuric acid solution. The stability of the electrodeposited ruthenium layer and the pseudocapacity of surface

Progress in Scanning Electrochemical Microscopy by Coupling with Electrochemical Impedance and Quartz Crystal Microbalance

ChemPhysChem, 2009
AbstractScanning electrochemical microscopy (SECM) is a powerful technique for performing quantitative measurements at a local scale. This paper covers the development of combinations of SECM with electrochemical impedance spectroscopy (EIS) and electrochemical quartz crystal microbalance (EQCM).

Electrochemical Quartz Crystal Microbalance Technique in Sonoelectrochemistry

ECS Transactions, 2009
The influence of the experimental conditions on the operation of a quartz crystal microbalance in an ultrasonic field was studied in water and different Cu electrolytes. An increase of the ultrasonic intensity and a decreasing distance between the ultrasonic horn tip and the surface of the quartz resonator caused an increase in signal noise and a ...

Time-resolved electrochemical quartz crystal microbalance

Journal of Electroanalytical Chemistry, 1994
Abstract A time-resolved electrochemical quartz crystal microbalance is described for the first time. In this equipment the frequency of the signal obtained equals the difference between the frequency of the working crystal resonator and the fixed frequency of a reference resonator.

Calibration of the Electrochemical Quartz Crystal Microbalance

Journal of The Electrochemical Society, 1991
The quartz crystal microbalance seems to be a very useful tool in electrochemical studies, but, up to now, no attempts have been made to calibrate the microbalance under electrochemical conditions. The aim of this paper is to determine not only the average sensitivity for different active areas but also the differential sensitivity as a function of the

Electrochemical study of methylalkylviologens using an electrochemical quartz crystal microbalance

Journal of Electroanalytical Chemistry, 1999
Abstract The electrochemical behavior of various 1-methyl-1′-alkylviologens (C 1 C n V 2+ : n =1, 7, 8, 9, 10, 12, 14, 16 and 18) was studied using an electrochemical quartz crystal microbalance (EQCM). Three different types of the frequency change-potential (Δ f – E ) curves were observed depending on the length of alkyl substituent during the ...

Quartz Crystal Microbalance Investigation of Electrochemical Calcium Carbonate Scaling

Journal of The Electrochemical Society, 1998
Electrochemical calcareous scaling was investigated by using a quartz microbalance in order to devise an accelerated scaling test. The chronoamperometric and the chronoelectrogravimetric curves were simultaneously recorded during scaling in carbonically pure waters.

Analytical Applications of the Electrochemical Quartz Crystal Microbalance

1992
The electrochemical quartz crystal microbalance (EQCM) has considerable potential as a sensor. The strategy is to use exchange of mobile species between a surface immobilised polymer film and a solution as a probe of solution composition. Film composition changes are monitored gravimetrically.
