The raw materials were submitted to carbonization employing a household microwave (Panasonic NN6460A) at 800W.
Notice that for CG and CH the n parameter is close to one, indicating an adsorption behavior typical of microporous materials.
Conclusions Coffee and pequi husks, and spent coffee grounds were tested as precursor materials in the production of activated carbons.

The home appliances and cars are mainly composed by thin metal materials, but the recycling use has become one of the major problems [1].
A few years later, recycled steels may become the main raw materials of steel industry [2].
The regular pattern of the crack extension in the thin sheet metal materials is discussed for modeI, mode II and mixed-modeI/II loading conditions to find the sensitive fracture factors.

Study on preparation of SiO2 optical fiber preform by SG method TANG Hui1,a, ZHANG Ji-peng1,b, GU Feng1,c, WANG Feng-chun1,d and WANG Ji-hua1,e 1School of Material Science and Engineering，Harbin University of Science and Technology，Harbin 150040，China aTanghui6003@sina.com, bzhangjipeng0922@yahoo.cn, c253223989@qq.com, dwfc19652000@yahoo.com.cn, e565175949@qq.com Keywords: SiO2 optical fiber perform; SG method; gel time; SiO2 dry gel Abstract.
Sol-Gel method is considered an innovative way to prepare optical fiber preform since it can enhance the utilization of raw materials and has remarkable commercial profits [12].
Experiment This paper first used TEOS and water as raw materials, hydrochloric acid and ammonia water as catalyst, formamide as anti-cracking agent to prepare SiO2 gel based on sol-gel method and then heat treated at different temperatures

Carbon nanotubes of high diameter / width ratio make it ideal low-dimensional materials objects.
Experiments also used scanning electron microscopy stick sample of carbon glue (Carbon Paint, the main component of the toner mixed bonding with the organic polymer materials and solvents) as a fixed material.
Comparative experiments show that these two materials between the electrode resistance> outside the scopeW10M of measurement in our instrument.
Non-metallic materials in general the specific heat capacity of 0.1 to 0.5, we used the quality of the carbon of the carbon plastic glue 2 to 3 g, then the heat capacity.

In case the assembly components are made of materials having different thermophysical properties, heat resistance [2] is also included.
In analysis of taper interference fit joints designers use the engineering calculation techniques well-proven at traditional materials and fits [3, 4].
To develop theory and engineering calculation techniques, experimental studies of load-carrying capacity of taper joints made of the above materials are required.
Mechanical properties of the materials are shown in Table 1.
