Introduction Two key challenges in the implementation of polymer-based nanocomposites are (i) obtaining good dispersions of the nanofiller and (ii) ensuring that the accompanying increases in melt viscosity do not compromise processing.
For this reason, initial efforts to investigate hybrid nanocomposite-composite materials in our laboratory have focused on thermoplastic composites, for which processing routes are specifically designed to overcome difficulties with high matrix viscosities [4].

High Throughput Speciation Analysis of Mercury in Water Environment by Short Column Capillary Electrophoresis On-line Coupled with Inductively Coupled Plasma Mass Spectrometry Li Bao-Hui1, a and Tian Bao-Juan2, b 1College of Environmental Science & Engineering, North China Electric Power University 2Baoding City, 071003, China, Department of Chemistry, Baoding College, Baoding City, 071000, China abhlli@mail.nankai.edu.cn btbj2001@163.com Keywords: Speciation analysis; hybrid techniques; short column capillary electrophoresis; inductively coupled plasma mass spectrometry; mercury.
As the most toxic species of mercury found in environmental and biological materials, MeHg(I) is of particular concern to people because it can be accumulated through the food chain.
Whether the sample uptake flow rate caused by self-aspiration effect of mcromist matches the make-up solution flow rate is the key to success.

FEM Analysis of the Deformation Behavior at Thickness Direction in Laboratory Plate Hot Rolling Jiyuan Liua, Zongan Luob*, Fuxian Zhuc and Chao Tiand State Key Laboratory of Rolling and Automation, Northeastern University, Shenyang, China aneu_liujy@163.com, bluoza@neu.edu.ral.cn, czhufuxian@163.com, dsdlgtys@163.com Keywords: FEM simulation, Thickness direction, Deformation behavior, Rolling pass reduction.
Because the rolling process finished before 950℃, the yield stress was set to 80MPa approximately, the other material parameter was shown in Table.1[9].

At the same time, the automotive industry is undergoing a major strategic shift in mechanical engineering going greener and safer, and also introducing new services for vehicles such as eco-driving support and access to Internet [2].
The profile loading phase ends by returning a user ID (ID, primary key in the user table) which will be used later on in the data monitoring and alarm handling thread.
