Consequently, the impedance differences
can be used to determine both the thickness of the specimen and the initial permeability of the
ferromagnetic materials.
We assumed that the materials being considered are all linear and isotropic, so the conductivity σ is a time-independent scalar constant.
For the permeabilityµ, since we assumed that the magnetic materials concerned are isotropic, that hysteresis could be neglected.

Materials and Methods
Samples Preparation
Ni–C composite thin films were prepared by the methodology described in Ref. [2] with the synthetic conditions for preparing the samples according to Table 1.
Analysis of the results obtained using the MountainsMap® 7 Software was based on the leveling and shaping operations for each sample, as well as generating three-dimensional views of the surfaces of the analyzed materials, together with all necessary scales and legends.
In addition, the investigation of the materials in nanoscale may be very useful for the study of the friction wear or the effects of body fluids on the particular material properties.

Introduction
As the technology advances, the demand for advanced materials with enhanced properties and functions increases.
The properties of clad composite material are determined by the selection of component materials to be joined, the stacking structure of different materials with various thicknesses and interface structure and properties between different materials.
Several method such as extrusion, rolling, electro-plating, overlay welding and explosive welding have been used for the clad materials production.
To examine the mechanical and fracture properties, the tensile test were performed using a Universal Materials Testing Machine (UNITED, US/SSTM) at room temperature.

A wide range of semiconductor materials is used as photocatalysts including TiO2, SnO2, and ZnO due to their ability under appropriate irradiation to form both oxidizing and reducing species required for the photocatalysis process.
These properties can be enhanced and expanded significantly by reducing the size of the active part of these materials to the nanoscale [4-6].
Some examples are the limitation in substrate materials, the impurities in the produced nanostructure, the high energy consumption to reach the relatively high temperature, and the necessity of vacuum conditions.
