EXPERIMENTAL PROGRAM 2.1 Instrumentation X-ray diffraction (XRD) model PW1877, Infra-red spectrophotometer (FT.IR) model 8300, Thermo gravimetric Analyzer (TGA), Melting point measurement model M.F B 600-010 F as well as other normal laboratory equipment and glassware were used. 2.2 Materials The phenolic resin (novalac) prepared in the laboratory, was used as a source of carbon for graphitization process.
Beyond these regions, the pyrolysis of the materials continued with slower rate and lose in weight are stopped, which tends to saturate in temperature range between 625-1000oC for the resins BMR and NMR, being in the temperature more than 1000oC for resin (NR).
Beyond these temperature, the pyrolysis and the weight loss of the materials continued slowly.

The key requirement of electrolyte material is the high ionic conductivity so as to minimize cell impedance.
The primary challenges are cost and durability, to be solved by materials selection and design engineering.
Composites materials are the next best alternative for anode.

Introduction Ab-initio methods are nowadays widely used in the investigations and/or development of novel materials.
The softer materials have larger amplitudes of vibration modes for a fixed average energy per mode.

Introduction to Investigation and Appraisal for Building Safety Project of Primary and Secondary School in Yunnan Province Wen Pan1, a, Yu Bai 1, b and Zhong Tao 1, c 1Faculty of Civil Engineering and Architecture, Kunming University of Science and Technology, Kunming, 650051, P.
However, the key point in this investigation step is to identify correctly the buildings belong to Grade A and D, for other two grades would go into further appraisal procedure and get more exact result.
Noticed the fact that there are many differences between codes for design and for appraisal, Executive Regulations for Investigation and Appraisal of Safety Project for Primary and Secondary School Buildings in Yunnan Province recommends the method for utilization of software based on current seismic design code to do appraisal, such as the adjustment of seismic factors and strength of materials, etc.

A tire is made of several layers of different materials bonded physically or chemically [2].
A peeling test is used for determining the force needed for separating two adhesive bonded materials [12].
This research tries to reduce the total time required only for vulcanization or curing time which is considered a key factor.

Factors Affecting the Performance of Molten Salt Heat Receiver Peijuan Li1, a, Yuting Cheng1,b and Shi Liu2,c 1School of Power, Energy and Mechanical Engineering, North China Electric Power University, Beijing 102206,China 2 School of Control & Computer Engineering, North China Electric Power University, Beijing 102206,China alipeijuan1234@sina.com, bcytko@126.com, cliushi_ncepu@yahoo.com.cn Keywords: Tower solar power; Numerical simulation; Molten salt receiver Abstract.
Because salt itself is very good melting regenerative materials, so that the heat transfer and heat storage of the solar heating system can be shared by the same medium, make the system greatly simplified[1-5].
