“…The QCM method has been applied to a gas adsorption measurement in gas phases as a thickness monitor of a vacuum evaporation device [23,24]. Nomura et al [25] have reported that the oscillator showed a stable resonance frequency in liquid phases. They used the QCM for quantitative analyses in liquid phases.…”

“…Quartz crystal microbalances are today routinely employed for this purpose in the thin films and coatings industry 10) . The interest in quartzes immersed in liquids originated from electrochemistry, where the electrode current was correlated with the mass transfer [17][18][19] . Unfortunately, the simple Sauerbrey relation does not necessarily apply in liquids.…”

SUMMARY: By analyzing the frequency shifts and bandwidths of coated quartz resonators the viscoelastic coefficients of the coatings may be derived. The paper gives an overview of the experimental procedure and the data analysis. Some examples of the application of this technique in the range of soft condensed matter are described. The swelling and plastification of polymer films in solvent vapor was monitored in-situ. We reported on measurements of the acoustic thickness of polymer brushes, the thickness of which varies with the solvent quality. The acoustic thickness is significantly larger than the optical thickness because the dilute outer portions of the swollen layer affects the acoustic behavior of the brush much more than the optical behavior. Sandwiching polymer layers between quartz plates and rigid overlayers expands the range of the applicability of the technique at the end of low film thicknesses, because the rigid overlayer adds inertia to the composite film and therefore enhances the stress acting on the layer of interest. Finally, the combination with optical birefringence measurements in Fabry-Perot configuration gives access to the stress-birefringence inside the polymer film. Normal stress components proportional to the square of the oscillation amplitude have been measured for the first time.

“…In 1980, a relationship between Df and fluid density and conductivity was identified by Nomura and Minemura (1980) but it was flawed because it was not based on a physical model. Kanazawa and Gordon (1985) established a relationship between Df and kinematic viscosity based on a physical model which couples the shear wave in the quartz to the damped shear wave in the fluid:…”
