Nanohardness and friction coefficients of this two kind of ceramic membrane have strong relationships each other but weak relations with elastic modulus. 1 Introduction Transition metals with strong antibacterial properties such as silver, zinc and copper are often used in preparing inorganic antibacterial materials [1-3] .A great deal of effort has been devoted in recent years to developing composite phosphate antibacterial materials produced by means of ion exchanging methods due to composite phosphate having adsorb function, ion changing function and catalyzing function.

The use of a laser for cutting brittle materials was first proposed by Lumley [2] in the 1870s.
The glass was the hard and brittle materials.

CuInS2 (copper indium sulphur, CIS in brief) quantum dot as photosensitive materials present many attractive features including: (i) high absorption coefficient (6×105cm-1) [6]; (ii) and direct band gap of 1.5ev, which is the optimum value for terrestrial solar cells[7] and (iii) appreciable photo lectrochemical stability while contacting with polysulfide electrolytes which act as hole transport materials.

Materials and Methods The crude oil samples were collected directly from the wellhead of each of the four oil wells namely Gilli-Gilli [Gelegele] 1 (GG1), Gilli-Gilli [Gelegele] North (GGN), Ovia 1 Short String (OSS) and Ovia 1 Long String (OLS) at Dubri producing Nigeria onshore locations at Ughoton and Gilli-Gilli [Gelegele], Edo State, Nigeria.
Studies have shown that crude oils are formed during categenesis of sedimentary organic materials which migrate from the rock sources into rock reservoir under the combined effect of temperature and pressure [4].
This suggests that the crude oils under study might have been formed from materials of terrestrial origin.

Morton, W.E. and Hearle J.W.S. found when a textile material is subjected to stress or strain; two basic phenomena occur, i.e. creep and stress relaxation.
Creep is extension with time under an applied load. [3] Usually, researchers use simple multiple-element models or more generalized integrated forms for modeling the viscoelastic behavior of materials, such as Azita Asayesh and Ali A.
Modeling the viscoelastic behavior of materials may involve using simple multiple-element models or more generalized integrated forms.
