Preface The 1st Environment-Enhancing Technology and Material Science International Congress was held successfully on Minhang Campus of Shanghai Jiao Tong University on 6-8th December, 2013.
The Environment-Enhancing material science and technologies should be economically viable, environmentally sustainable and have the potential to ultimately meet the human need for liquid fuel.
We envision that Environment-Enhancing material science and technology should be explored aiming at meeting our entire fuel need, achieving net-zero carbon emission and water use, and recycle the nutrient in the feedstock.
During this congress, the attending scholars presented the applications of environment-enhancing technologies, especially those related to material science, in China and other parts of the world.
Jiang investigated the antimicrobial effect of nano-SiO2 particles in gelatin and chitosan based wound dressing materials.

Material Properties.
When the material property was assumed as plastic, the kinematics hardening rule was adopted to simulate the loading and unloading behavior of the material.

The reflectance became minimum when the length arrive at 50% of wavelength, it get maximum when size reach 90% of wavelength, then it has a small decrease till 100%. 1.Introduction Magnetostrictive guided wave detection technology is based on the theory of magnetostrictive effect of ferromagnetic materials.When ferromagnetic material effected by an external magnetic field, the dimensions is changed and the magnetostrictive strain is produced.The magnetostrictive effect is the inherent characteristics of the ferromagnetic materials.

Numerical Simulation of Semi-solid Billet Preparation by Equal Channel Angular Extrusion Xiaohua Zhang 1,a , Yanying Zhang2,b, Dezhong Wu1,c and Shoujing Luo 1,d 1 School of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, P.R.China 2 School of Mathematics and Computer Science, Harbin Normal University, Harbin 150025, P.R.China a zhangxiaohua11@gmail.com, b duzm@263.net, cwdz9018@yahoo.com.cn, dluosj@hit.edu.cn Keywords: numerical simulation; semi-solid billet; ECAE Abstract：Equal channel angular extrusion (ECAE) is a technology of refining crystal grain.
However, the effect of ECAE is different for different materials or die arrangements [8, 9].
The whole distribution of material appears a sector to tally with the frame of die.
So the mechanism of ECAE is related to the materials extruded properties.
