It should be noted that waste landfills are a heterogeneous mass of substances and materials with different origins and properties (Fig. 1).
Due to the variety of substances and materials in waste landfills, they accumulate a significant amount of combustible substances from the composition of solid combustible materials (SCM).

Among these types, the most widely used is a gas sensor with the principle of resistivity changes using metal oxide materials, such as SnO2, WO3, In2O3, ZnO, etc. [2-5].
Meanwhile, to increase the sensitivity of the material to the detected gas can be done with the use of new types of metal oxides are more sensitive, the use of materials with nanostructures, the use of catalysts/doping, as well as the use of new technologies to grow the material. 4.1.1 Material metal oxide nanostructure The use of materials with nanostructures will provide a higher total surface area for the gas.

Introduction With the development of nano science and technology, more and more attention has been paid to the material’s property on nano scale.
It has been used in physics, material science and machining industry.
Journal Title and Volume Number (to be inserted by the publisher) 181 Molecular Dynamics Simulation Single crystal silicon microhardness experiment in nano scale is simulated with molecular dynamics.
This phenomenon exists in the microhardness experiments of different materials, such as the experiment of microhardness of Si substrate by Bhushan and Koinkar [8], the research by G.
Stowers: Material Research Symposium Vol. 140 (1989), p. 119 [3] J.

In this study, test materials with 4 different degradation levels were prepared by isothermal aging heat treatment at 630�.
In this study, the aging materials were made to simulate the used specimen in the field by an artificially accelerated aging method.

The current volumes of vanadium extraction from natural raw materials do not match the demand of the market.
Nowadays, the main mineral raw materials of vanadium are titanomagnetites, which hold about 90 % of vanadium.
Materials and Methods Hydrometallurgical method was applied to extract vanadium from studied slags.
