Analysis of XRD patterns showed that ZnO clusters are single hexagonal phases of wurtzite structure with no other impurities.
Wet chemistry methods have attracted much attention from materials scientists and chemists.
Surfactant assisted wet chemistry methods have been recently applied to the synthesis of ZnO nanorods with good crystallinity, chemical stability and thermal stability.
The structures, morphology and the Raman spectral properties of ZnO microcrystals are investigated.
However, regardless of the conditions during synthesis, the crystal structure of the final product was always hexagonal wurtzite structured ZnO.

This was due to the olefinic structure of shellac added by chlorine was recovered while the chlorine was substituted by hydrogen.

The micro- structure was observed by a field emission gun scanning electron microscopy (FEGSEM).
From (b) we can see that typical Ti3AlC2 with laminated structure appear beneath the tribo-glazing layer.
(b) Morphology of Ti3AlC2 with laminated structure appears beneath tribo-glazing layer (labeled with arrow).
Owing to such structure as same as graphite, sliding fraction processes along laminated direction with least resistance, while frictional chemistry reaction happened on the surface layer and formed oxide scale, some of them may be worn and become into sticky composite state, and so, series of MAX materials have good self-lubrication as the same as graphite.

The pore structure of the activated carbon was characterized by N2 adsorption at 77K.
Coconut shell is suitable for preparing microporous activated carbon due to its excellent natural structure and low ash content [12].
The adsorption isotherm is the information source about the porous structure of the adsorbent, heat of adsorption, characteristics of physics and chemistry and so on.

Introduction Nowadays, much attention has been paid to the fabrication of hierarchically structured zeolite [1-3].
Such hierarchical materials usually exhibit well-ordered and interconnected pore structures.
The results showed that the novel material possessed micro-meso-macroporous structure with high mechanical stability.
N2 adsorption-desorption measurements were used to determine the micropore and mesopore structures of the hierarchical zeolite.

It had been previously shown that the resin reinforced by carbon fibers (CFRP) could be used in engineering structure because of their high stiffness and corrosion resistant.
At the same time CFRP can feedback the change of stress in the inner of structure timely and has been used as a kind of strain sensor in the concrete structure because of its piezoresistive capability [1~3].
