“…The differential mass sensitivity varies across this area. The integral mass sensitivity is defined by the integral of the differential mass sensitivity over the acoustically active area [2,3,[18][19][20][21]. For the typically used round shape, thickness shear wave piezoelectric oscillators, C f is expressed as:…”

“…Among the many piezoelectric materials, α-quartz is most commonly studied and used as piezoelectric oscillator, because desired features can be achieved through various cuts of its native crystals [2,3,[27][28][29]:…”

“…These cuts should be specified, as their properties are very important for the piezoelectric sensor performance. Electronic surface films and electrical contacts are usually accomplished by vacuum deposition, sputtering or electroplating of metal films on both crystal faces [3,8].…”

“…A lack of conformance with the Sauerbrey equation may be traced back to viscoelastic effects, high-mass loadings, surface roughness, surface stress, interfacial slippage, nonuniform mass distribution, and changes in the ambient temperature [3,7]. These non-mass-related changes in the measured frequency are related to changes in the morphology of the selective surface film (viscoelastic effects), decreasing sensitivity of the QCM (high-mass loading), trapping of liquid in surface cavities (surface roughness) [5,41], asymmetrical cell arrangement (surface stress), and the coupling between the oscillator surface and the adjacent solution (interfacial slippage).…”

“…The present report addresses mostly the application of piezoelectric sensing devices in electroanalytical chemistry based on the quartz crystal microbalance (QCM) technology, and it has been coordinated with relevant documents of physics and electrical engineering [1][2][3][4][5][6][7][8][9][10][11][12][13]. The piezoelectric effect arises when pressure applied to a dielectric material deforms its crystal lattice which causes separation of centers of opposite charges giving rise to dipole moments of molecules.…”

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.

A review is given of the present day problems related with experimental and theoretical studies in nanotribology, a new apatterning branch of physics, which pertains to investigations of the atomicscale friction, adhesion, wear and lubrication. When analysing the experimental results a major point of interest is related with ªdryº adhesion friction between the tip of an atomic force microscope and an atomically smooth surface. However, many other physical effects are considered, too, such as chemical ones, triboemission of particles, conduction in metallic nanocontacts, etc. For the first time, some new results in theoretical elaborations of adhesional (static) and dynamical (velocity-proportional) friction are discussed, as well as some results obtained using the computer simulations. A brief discussion of nanostructural friction measured with the quartz crystal microbalance technique and the surface-force apparatus is also given.
