To increase the durability of bamboo it is important to find an easy method to fill the micro and meso structure of the biological matrix using a nano-structural material with an anti-fungical activity.
For the synthesis of silver nanoparticle in flow mode two syringe pumps were used, purchased from Future Chemistry, and one glass micro reactor from Micronit.

The chemistry and physical properties of the hot face refractories with and without phosphate additions used in the gasifier tests is listed in Table 1, and an average coal ash chemistry similar to the coal ash chemistry that samples were exposed to during the approximate 8 months of testing is listed in Table 2.
Chemistry was similar to coal ash chemistry used in the gasifier.
Table 3 - Chemistry of high chrome oxide samples without phosphate additions as received and at specific locations shown in Fig. 4.
Gases have one main path to be removed, through the porous structure of the refractory, which is a diffusion process.
This valance change of the slag Fe will be subject to influence by the low oxygen partial pressure on the gasifier side, resulting in a balance between the two structures that is controlled by diffusion.

Raman Spectra Application in Chemistry.

The XRD pattern shows that crystal structure of the sample with no Zn is basically single-phase.
The SEM results indicate that the samples have porous structures and the gain size decreases with the content of Zn increasing.
Fig. 1 shows the SEM images of the grain structure of fracture of the pellets with different dopant content.
The samples have porous structures and the gain size decreases with the content of Zn increasing.
The dielectric constants are less than that in other papers reported obviously because of their mesoporous structures.

Chromium carbide Cr7C3 was observed in the coating structure after heating to above 1000 °C.
A more detailed structure image of the particles was obtained with the help of SEM (Fig.1,d).
The structure mostly consists of two types of grain.

The hardness and elastic constants of chief structure which constituted by sp3-hybridized state carbon atoms far and far higher than the impurity structures which constituted by sp2-hybridized state carbon atoms.
The above situation is, however, dramatically different when density of DLC film is 1.5g/cm3 .The distinguish for the friction in soft and hard direction is nonexistent, which illuminate the sp2 hybridization C atoms changed the chemistry nature of the DLC films and influenced the adhere function very greatly.
The relationship between structure and stress As expected, structure characteristic influences the friction coefficient and residual stress of DLC film greatly.
