The secondary raw materials restarted in the production process can consist of at least three qualitatively different categories of materials: - with the same characteristics as the original materials - with characteristics of new materials, replacing the traditional ones in the same applications from which they originated - with characteristics of new materials, replacing traditional ones in applications other than those from which they originated The first category includes those materials which, after having been separated in the treatment phase, can be added to the virgin material at any stage of its transformation process and are no longer distinguishable from it.

Not like typical MCM-41 mesoporous materials, it is found that results of analysis are a little different and morphology of mesoporous materials synthesized in acid media does not rely on silicon sources, regardless of organic or inorganic silicon source.
Introduction Mesoporous materials are generall synthesized in alkaline hydrothemal method.
Conclusion In acid media, mesoporous materials can be made from inorganic silicon source like organic silicon source on mild condition.

Simultaneously, the service behavior of the bamboo/steel slabs is pecfect and there is execllent composite effect between the two different materials.
And the strain is basically the same at the interface of the two kinds of materials.
Bamboo/steel composite beam composites with two different plate materials by structural adhesive.
Because the thickness of composite beam's flange plate is large relatively, the strain gradient changes intersection between surfaces of two different materials.

Hypotheses about the Tools Origin of Textile Materials Yuan Taoa, Weidong Yu*b Key Laboratory of Textile Science & Technology, Ministry Education, Donghua University, Shanghai, China a2010taoyuan@163.com, bwdyu@dhu.edu.cn Keywords: Origin; Tools; Textile materials; Primitive man.
Performance Forms of Primitive Textile Materials Single Fiber Shaped Textile Materials.
The first hypothesis can be proposed that textile materials are firstly used as tools, that means the origin of textile materials is tools, and the origin time of textile materials is not later than stone tools.

On the other hand, a new process for manufacturing hybrid metallic materials is described.
These semi-finished materials consist of two different metallic materials and are both to be heated into the semi-solid state.
