Effect of low molecular weight ethylene homopolymer on structure and properties of bimodal high density polyethylene Xingbo Shi1,a, Julin Wang1, b *, Xiaoping Cai2,c 1 College of Materials Science and Technology, Beijing University of Chemical Technology, Beijing 100029, China 2 Jilin Petrochemical Co.
High molecular weight materials exhibit good toughness, but they are inherently difficult to process because of their high viscosity.
Experimental Materials and samples preparation Supply of HDPE and their parameters are shown in Table 1 and Fig. 1.

Concerning the fabrication and performance study of point defect for three dimensional photonic crystals in electromagnetic wave band, E.Ozbay has obtained point defect photonic crystals with woodpile structure in order to test their effect on photonic band gaps by fabricating some rods with metallic materials.
In conventional direct SL method, the materials used are very limited, the sintering shrinkage is larger than 30%, and the tested and simulated of band gap could have large difference.

According to OECD, resource productivity is defined as the quantity of output produced per unit of materials inputs used in the production of the output.
Material intensity indicators are the inverse of productivity indicators, so the energy intensity(EI) can be defined by: Material Intensity, and GDP represents the development of society and EC represents the total consumption of energy such as coal, oil, and gas etc.

Affinity of dyes to textile materials controls several properties of dyeings, the most important of them is wash fastness.
Reductive destruction of dyes is also important for cleaning the materials after dyeing with disperse dyes in order to improve wash fastness of dyeings and reductive decoloration of effluents.
