Introduction Activated carbon is an important porous adsorbent with developed pore structure and huge specific surface area and chemically stable.Widely used in industry, agriculture, national defense, medical and daily life.It becomes a indispensable adsorption material [1-2].
The molecular structure of thermosetting epoxy resin is a crosslinked three-dimensional network structure.It has good mechanical properties and heat resistance,so that it’s hard to be recycled and reused [8].

Sputter coater (Emitech KX550) was then used to deposit Gold (Au) electrodes to complete the sensors structure.
This nanoscale Al doped ZnO structure provides a large surface-to-volume ratio which increases the sensitivity of the sensor.
The condition provides a good UV detection signal with visible and NIR filter free sensor structure which visible light influenced signal could be ignored.
Such linear I-V curves for all conditions indicate the ohmic behavior of Au electrode with nanostructured ZnO thin film structure.

The crystalline structure of material also contributes in improving the conductivity of TiO2 thin film.
As deposited sample show the highest resistivity value which might due to it`s amorphous structure.
XRD measurement result shows that as deposited sample exhibit amorphous structure while annealed sample show crystalline anatase TiO2 structure.
The crystallinity structure of TiO2 particles is increased when the annealing temperatures is increased.

The microstructure and phase structure of WO3 nanorod were characterized by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM), respectively.
Crystalline structure of the WO3 nanorods were studied by X-Ray diffractometer (XRD; TTRAX III-RIGAKU).

Mechanical Properties of Machinable Zirconia Dental Composites Wenxu Li1, Hua Zhao 2, Ying Song 1, Bin Su 1 and Fuping Wang1 1 Department of Applied Chemistry, Harbin Institute of Technology, Harbin, 150001, China 2 School of Materials Science & Engineering, Harbin Institute of Technology, Harbin 150001, China Keywords: Zirconia; Calcium phosphate; weak interface; machinability Abstract.
On the other hand, strong interfaces between Zirconias increased the integrality of the ceramic structures.
The strong interfaces between ZrO2 phases ensure the integrality of the material structures, which improve the machinability of the composites.

Most of these PAM’s are created in certain laboratories from special materials, which are combined due specific technology in order to obtain a special structure, in order to imitate the human muscle.
The working principle combines the elastic tubular membrane principle, which is impermeable to air, with a rhombic fiber structure.
These types of structures are classified like composite materials with polymeric fiber matrix and in this field of activity are not many investigations.
Here the presented test bench has a simple structure, the experimental methodology is easy to follow and the results are accurate in the range of pressures normally used.
In order to develop a more advanced model it is necessary of a multidisciplinary research group in order to combine the most advanced sciences at his moment, like: composite materials, textiles - microfibers, chemistry and also mechanical science.

Results and discussions Structure and morphology of CaCO3 and ZHSCC.
Fig. 2 showed there was no evident interaction to cause the purity and structure of CaCO3 after coated.
As shown in Fig. 3c, the structures of ZHSCC were irregular with varying sizes and shapes.
With the uniform and distributed structures, the flame retardants can be dispersed in substrate material better.
It is demonstrated that the size, crystal structure, and morphology of ZHSCC may be controlled by SDBS.

A linear electrical system is applied for suppressing the chaotic vibrations which limit the performance of the motion in the mechanical structure.
The structure consists of a mass , a viscous damping coefficient , a linear spring constant and a nonlinear spring constant .
The structure is excited to a source of limited power supply with mass unbalanced and eccentricity .

Figure 2 shows the cross section morphological structure of the P-0 membrane and P-3 membrane.
Another difference can be seen in the macrovoid structure in the sublayer of the two membranes.
