TiNb coatings can be prepared on substrates of widely-used materials, and promise not only improved properties but also a less high price of potential TiNb implants.
Experiment and methods Four types of identically prepared substrates made of different materials were used for the TiNb layers.
The hardness of the substrates and of the evaporated layers were measured using the Nanotest system (Micro Materials Ltd., UK) with a Berkovich indenter.

There are some materials to synthesize glycidyl nitrate: glycidyl tosylate [6-9], epichlorohydrin [10] and glycerol [11].
Materials and methods The reactants used in the experiments are nitrated glycerol solution, the products of glycerol nitration, which are get from experimental before.
Until now there have been found few journals that discusses the cyclization of 1,3-DNG.

Introduction Concrete is the first important material for construction, most buildings, bridges, highways, piles, industry constructions made using concrete, cement which is the only bonding material in concrete manufactured in large mills, and the production of cement causing large amounts of harmful gasses that causing air pollution.
Concrete is an environmentally ugly material in manufacture, the manufacture of Portland cement responsible for 5 percent of human-caused emissions of the greenhouse gas carbon dioxide [6].
Experimental Procedure 1- Materials used: ordinary cement type I used in all mixes, coarse and fine aggregate confirming Indian standards (I-S-838) [7] used with grading shown in tables 1 and 2 Super plasticizer type CF-555 used for modified mixes of concrete. table 3 shows some properties of CF-555 liquid polymer super-plasticizer used in this study. 2- Mixing and tests: reference mixes details show in table 4, the reference mixes which do not contain any admixture have different ratios of cement for each 1 cubic meter of concrete include 150, 200,250, 300, 350,400,450,500, and 550 Kg/1m3.

The calculated values of second order elastic constant (SOEC), bulk modulus and other mechanical properties of three concentrations (x = 0.00, 0.08 and 0.40) at ambient pressure are presented in Table 3.The elastic constants are important for materials because they provide valuable information about the nature of the forces and bonding characteristics of materials.
