An electronic oscillator with automatic gain control: EQCM applications

Sensors and Actuators B: Chemical, 1996
Abstract An electronic oscillator for use with thickness-shear-mode acoustic wave sensors is described. The oscillator monitors not only the resonance frequency of the sensor, but also provides an automatic gain control signal that monitors the energy dissipated by the sensor.

Electropreparation and characterization of polyNiTSPc films. An EQCM study

Journal of Electroanalytical Chemistry, 2005
Abstract Thin films of polyNi(II)tetrasulfophthalocyanine (polyNiTSPc) electrodeposited on a gold electrode by potential cycling in 0.1 M NaOH solutions containing 1 mM Ni(II) tetrasulfophthalocyanine were studied by cyclic voltammetry, electrochemical quartz crystal microbalance and impedance techniques.

EQCM ISTRAŽIVANJA PSEUDO-KAPACITIVNIH SVOJSTVA HIDRATIZIRANOG RuO2

2010
Poznato je da rutenij oksid ima vrlo visoke struje oksidacije i redukcije u širokom području potencijala, reverzibilne cikličke voltamograme te svojstvo da se može oksidirati i reducirati više tisuća puta a da ne dođe do značajne promjene u sastavu materijala.

EQCM Study of Anodic Film Growth on Valve Metals

Journal of The Electrochemical Society, 2004
A comparative study of anodic film growth on niobium, zirconium, and tungsten in 0.4 M Na 2 SO 4 + 0.1 M H 2 SO 4 was performed using the rotating electrochemical quartz crystal microbalance (EQCM). Potential sweep as well as potential step and hold experiments were performed in the range between open circuit and 8 V SHE .

Monitoring formation of poly(neutral red) film by EQCM

Russian Journal of Electrochemistry, 2007
An electrochemical quartz crystal microbalance (EQCM) is employed for monitoring the growth of poly(neutral red) films on platinum in the electrolytic solution containing 5.0 mmol dm−3 neutral red, 0.3 mol dm−3 H2SO4, and 0.5 mol dm−3 Na2SO4. The in situ measurement of the frequency changes of the EQCM reveals that both the adsorption/desorption of ...

Relative Surface Area of the EQCM Quartz Crystals Vibrators

Journal of The Electrochemical Society, 2000
The relative surface area, R sa , i.e., the ratio of the surface area in a three-dimensional space to that in a two-dimensional space, of quartz crystal vibrators, used for an electrochemical quartz crystal microbalance (EQCM), was determined by atomic force microscopy in air, by coulometry in solution, and derived from the Brunauer-Emmett-Teller ...

Material sustainability and EQCM exploration. A pertinent coupling?

2022
Material sustainability studies is of prime interest in different domains of application due to major environmental issue. Most are solved by using well adapted protective films in order to limit the material degradation. Nevertheless, in some cases the efficiency is not enough and it is well suitable to have a deep exploration of what happens during ...
