This chapter describes the results of an ongoing study we are conducting into the nanoscale mechanical properties, chemical composition and structure of healthy enamel, carious lesions and the acquired salivary pellicle layer. A variety of material characterization techniques are being used, including nanoindentation, scanning electron microscopy (SEM), electron microprobe analysis (EMPA), scanning acoustic microscopy, atomic force microscopy (AFM) and time-of-flight secondary ion mass spectroscopy (TOF SIMS).

The deformation behavior of bulk ZnO single crystals was studied by a combination of spherical nanoindentation and atomic force microscopy [101]. ZnO exhibited plastic deformation for relatively low loads (>4—13mN with a 4.2 mm radius spherical indenter). The average contact pressure hardness H and Young s modulus as a function of indenter penetration were determined by analyzing partial load-unload data. The hardness value of ZnO is measured to be 5.0 0.1 GPa at a plastic penetration depth of 300 nm. The Young s modulus remained essentially constant over the indenter penetration depth, with =111.2 4.7 GPa. Previous indentation studies performed mostly on polycrystalline ZnO have reported a wide range of H ( 1.5-12 GPa) and ( 40-120 GPa) values. However, it should be noted...

The experimental analysis of particulate-filled nanocomposites butadiene—styrene mbber/fullerene-containing mineral (nanoshungite) was fulfilled with the aid of force-atomic microscopy, nanoindentation methods, and computer treatment. The theoretical analysis was carried out within the frameworks of fractal analysis. It has been shown that interfacial regions in the aforementioned nanocomposites are the same reinforcing element as nanoliller. The conditions of the transition from nano to microsystems were discussed. The fractal analysis of nanoshungite particles aggregation in polymer matrix was performed. It has been shown that reinforcement of the studied nanocomposites is a true nanoeffect. 

Many techniques have been developed to measure the Young s modulus and the stress of the mesoscopic systems [12, 13]. Besides the traditional Vickers microhardness test, techniques mostly used for nanostructures are tensile test using an atomic force microscope (AFM) cantilever, a nanotensile tester, a transmission electron microscopy (TEM)-based tensile tester, an AFM nanoindenter, an AFM three-point bending tester, an AFM wire free-end displacement tester, an AFM elastic-plastic indentation tester, and a nanoindentation tester. Surface acoustic waves (SAWs), ultrasonic waves, atomic force acoustic microscopy (AFAM), and electric field-induced oscillations in AFM and in TEM are also used. Comparatively, the methods of SAWs, ultrasonic waves, field-induced oscillations, and an AFAM could minimize the artifacts because of their nondestructive nature though these techniques collect statistic information from responses of all the chemical bonds involved [14].
