In structural products, the decrease in density of material leads to highest weight reduction that leads to lightness of product with slight change in material properties [1-2].
Strength to weight ratio were another dominant factor and the key positions for aluminium-based light alloys, magnesium and titanium-based light alloys.
It clearly shows that the hardness has an influence on the wear resistance property of the material.
It shows that the wear loss of the material increases when the applied load increases.

Mechanical characterization of human dentin: a critical review Ilaria Cappelloni1,a and Roberto Montanari1,b 1Department of Industrial Engineering, University of Rome – Tor Vergata Via del Politecnico 1, 00133 Rome - Italy acappelloni@ing.uniroma2.it, broberto.montanari@uniroma2.it Key words: dentin, structure, mechanical properties, mechanical tests, FIMEC test.
However, Eq. (5), properly related to isotropic materials, is not the correct relationship to calculate dentin Poisson’s ratio.
FIMEC (Flat-top cylinder Indenter for MEchanical Characterization) is an instrumented indentation technique, developed by one of the authors to test metallic materials on a local scale.
The interpolating function consists of two exponential terms with relaxation times τ1 and τ2, which describe two different mechanical processes typical of porous materials.
Acknowledgments The authors are grateful to Mr Piero Plini and Mr Benedetto Iacovone of the Department of Industrial Engineering, University of Rome - Tor Vergata, for the assistance in sample preparation and FIMEC tests.

Fly ash cenospheres (FACs) are part of the fly ash and widely considered as valuable materials for manufacturing various value-added products [7].
Some mesoporous materials, such as silica, palygorskite, and activated carbon have been successfully grafted with 3-aminopropyltriethoxysilane (known as KH550 or APTES) to provide anchoring sites for different organic compounds or metal.
Materials and Methods Materials.
Table 1 summarizes the atomic percentages of surface chemical elements of these materials.

This technique has also been used to set structural health monitoring systems in civil and aerospace engineering [5–7].
Highly durable materials are used to package and to protect bare OF sensors against the poor shear resistance of bare OFs, which have long working lives and a strong capability to survive disasters [8–9].

Wettability alteration is one of the mechanisms of (EOR) by alkaline flooding and so wettability plays a key role in determining fluid distributions and consequently the multiphase flow and transport in petroleum reservoirs.
In fact, nanoparticles [29-31] are very active and energetic materials with a high tendency to form nanotextured surfaces in combination with surfactants, resulting in a significant change in the interfacial properties of the system.
Experimental Details Materials and Methods 1- Synthesis of SiO2 nanoparticles The synthesis of spherical fine SiO2 nanoparticles was prepared from Si (OC2H5)4 (TEOS) by sol gel and partially acidic hydrolysis method. 5 ml acac (acetyl acetone) surfactant in 2 gr. citric acid solution added during 0.5h with stirring at 40-50° C.
In addition, SiO2 (1) 3% (54.51 altered to 46.83) and for concentration of 8% (50.80 changed to 47.42) could indicate important reduction in S.T after the annealing process and surface engineering of nanoparticles in based distilled water (S.T for H2O= 72.566 mNm-1).

This is may be due to the impact of harsh atmosphere on the efficiency of the PV modules, mainly soiling and materials degradation [10-12].
As results, Greenius give the energy outputs for the simulated system in different times steps: hourly, daily, weekly, monthly and annual as well as some key results such as the performance ratio and yield field in the case of PV systems.
