From materials science point of view, human tooth is a functionally graded material consisting of several layers.
Enamel consists of 92–96 wt.% of inorganic substances, 1–2 wt.% of organic materials and 3–4 wt.% of water.
Experimental materials and procedure Chemical analysis of white wine used as a corrosive medium was estimated using the atomic emission spectroscopy in conductively coupled plasma.
CSM is useful for the measurement of nanomechanical properties of non-homogenous materials, such as corroded teeth, in which the mechanical properties changes with the indentation depth.

The Pt is functioned as the catalytic material for the reduction [3].
To overcome the problem, several inexpensive materials have been developed as the catalytic materials to replace the Pt, among which graphite shows potential application to a certain degree due to favorable catalytic activity, chemical stability and low cost [5,6].
Therefore, graphene nanosheets (GNs) are developed and usually used as a modifier with other low cost catalytic materials to construct composite counter electrodes, such as multi-walled carbon nanotubes/graphene electrode and polyaniline/graphene electrode [8,9].

Introduction Bulk nanostructured (NS) materials are perspective constructional and functional materials due to their unique combination of physical and mechanical properties.
Fundamentally, these studies are of interest to obtain new information about behavior of the processes of plastic deformation in the constrained conditions and processes of the evolution of the defective structure in the materials.
