An ELCHEMA Model EQCN-700 electrochemical quartz crystal nanobalance was used in combination with an ELCHEMA Model PS-205B potentiostat in special experiments. As working crystal, an ELCHEMA QC-10-AuPB laboratory quartz crystal with 14 mm of diameter (active area of 0.196 cm2) was used.

Another instrument has been advertised recently by ELCHEMA (Potsdam, NY). The electrochemical quartz crystal nanobalance system model EQCN-5(K) is capable of measuring simultaneously the voltamperometric characteristics and mass changes during an electrochemical process. The reported potential... 

The quartz crystal nanobalance (QCN) can be combined with practically any electrochemical methods, such as cyclic voltammetry, chronoamperometry, chronocoulometry, potentiostatic, galvanostatic, rotating disc electrode [11], or potentiometric measurements. The EQCN can be further combined with other techniques, e.g., with UV-Vis spectroscopy [12], probe beam deflection (PBD) [13], radiotracer [14], atomic force microscopy (AEM) [15], and scanning electrochemical microscopy (SECM) [16]. The concept and the instrumentation of... 

Quartz crystal nanobalance is a thickness-shear-mode acoustic wave mass-sensitive detector based on the effect of an attached foreign mass on the resonant frequency of an oscillating quartz crystal. The QCN responds to any interfacial mass change. The response of QCN is also extremely sensitive to the mass (density) and viscoelastic changes at the solid-solution interface [1-8]. 

Electrochemical quartz crystal microbalance (EQCM) or nanobalance (EQCN) is a combination of a piezoelectric sensor, i.e., a quartz crystal nanobalance (QCN) and an electrochemical cell containing the sample electrolyte solution, the reference electrode, as well as other electrodes as required, driving oscillator, amplifiers, and readout units [1-7]. In most electrochemical experiments, the piezoelectric crystal. 

The authors are pleased to present here the second edition of the book Electroanalytical Methods. Guide to Experiments and Applications. All chapters have been carefully revised and updated, and a new chapter, devoted to the use of the electrochemical quartz crystal nanobalance, has been added.

All derivatives of the benzo-hydroxamic acid inhibited copper corrosion more effectively than BHA itself. The efficiency was affected much more by hydrophobic bulkiness in the phenyl ring than by the electronpushing or electron-attracting character of the substituents. The results attained by electrode impedance spectroscopy and quartz crystal nanobalance techniques led to recognition that the higher efficacy was not due to the inductive effect of the substituents, as both chloro and methyl substitution led to enhanced inhibition. The most important factor is the hydrophobic bulkiness. In the inhibition process, the inhibitor molecule is attached to the copper surface by the polar group (CON"), and the apolar hydro-phobic moiety may block the metal surface... 

However, recent studies using an electrochemical quartz crystal nanobalance revealed that the platinum oxides are not hydrated (Birss et al. 1993 Harrington 1997 Jerkiewicz et al. 2004) thus, at 0.85-1.15 V a half monolayer (0.5ML) forms from chemisorbed oxygen rather than OH. Figure 1 depicts the proposed... 

Indeed, one is tempted to call it a quartz crystal nanobalance, but we shall maintain the commonly used name of QCM, in order to avoid confusion.
