When they are deposited on soft substrate such as pure titanium, plastic deformation is prone to occur with high loads which will lead to the film decohesion because soft material may not be able to provide adequate support for the hard TiN film.

Preliminary Study on Microstructure of Jute Fiber QIAN Jing-fang1,2,a, TANG Yi-yong2,b 1 Xin Jiang University, Wulumuqi, China 2Key Laboratory of Textile Science & Technology, Ministry of Education, Shanghai, China a qjf@dhu.edu.cn,b tangyiyong@mail.dhu.edu.cn Key words: Crystallinity, Crystalline orientation degree, IR spectrum, Chinese jute, Bangladesh jute Abstract.
In the past due to the limitation of the manufacturing technology and fiber’s inferior properties, such as stiffness and harshness, jute fibers were manly used to produce bags, hessian and other packing materials.
In the 21st century, with the strengthening of the ecological and environment awareness, jute fiber has been popularly regarded as a new sustainable-development and environment-friendly eco-textile material and become a hot spot for research and development.
In this paper, we chose a kind of Chinese jute and a kind of Bangladesh jute as raw materials for apparel and household textiles in China, analyze their crystallinities, crystalline orientation degree, infrared spectroscopies, as well as the effect of acids, alkalis, oxidants treating on aggregation structure.

(1) To quantity the absorption capability of the solar cell structure in the wavelength region of interest, we defined a normalized weighted integrated absorption for the AM 1.5G spectrum (2) The absorption enhancement with the active material is given in the following formula: (3) where Aint (with NPs) and Aint (without NPs) are the normalized weighted integrated absorption with and without metallic NPs in the OSCs, respectively.
However, it should be noted that the volume of active materials is decreased because of the introduction of MNPs.
Despite this, the total amount of light absorption is still increased, because the effect of MNPs outweighs the reduction of omitted polymer materials.

Introduction Because of many good performances, metal materials have been widely used in various industry and departments of national economy.
Because most of the metal elements exist in ore, metal smelting is a premise process of metal materials production.
Using ores as raw materials in non-ferrous metal smelting producing, ores generally contain harmful ingredients, such as As, Pb, Cd, Hg and so on.
Secondly, the chemical composition of smoke is very complex because the chemical composition is varied by different technical process, raw materials and fuel.

Based on the above-mentioned, peroxides are strictly unstable and active materials.
OPs are self-reactive chemical materials widely employed as initiators and cross-linking agents for polymerization reactions, since they typically form free radicals upon decomposition [9].
