Hence, the incorporation of multi-walled carbon nanotubes (MWNTs) into the CB-filled polymer was expected not only to reduce the required CB loading, but also to improve the electrical properties of the composites due to their high conductivity and network structure [5,6].

Lundberg [4] synthesized Nb2WO8 and studied the crystal structure.
Results and discussion Structure and properties of photocatalysts In order to obtain the optimal preparation condition of Nb2WO8, the effect of heat treatment on the preparation of Nb2WO8 was investigated.

The tribological mechanism was discussed by analysis of solid film structure of rubbed surface using XPS and SEM.
Figure 3 SEM morphologies of worn surface lubricated with 5Cst(left) and 2.0wt% DXAD (right) under392N It indicate that severe scuffing occurs with lubrication of 5Cst alone, taking on grain abrasion characteristic, while only slight frictional tracks appear with lubrication of DXAD, and there has appeared some layer structure matter, which assuming the characteristics of corrosive worn.

Existing researches on the absorbing properties of cement-based materials show that adding nano-materials can improve the performance of wave absorbing, 10-15mm thick samples made from cement mixed with nano-TiO2 powder were found very effective within 2-18GHz spectrum.[6-9] In this paper, the electromagnetic wave absorption performance of modified cement base material were studied, this research has important academic value in the development of large span structures’ camouflage technology, and improving stealth properties of concrete structures, etc.

This design approach has been applied to many industries such as electronic device, transportation, chemistry, pharmacy, food and beverage, material, energy, and service [4].
Research [11] developed a methodology for materials selection for an automotive structure.
The methodology integrates structural optimization with environmental impact assessment.The optimization and environmental impact assessment are conducted separately and accounted for by normalization and giving weight to find the best material for the automotive structure.

Both the melted and sintered Zircaloy presented hexagonal α-zirconium structure whit small difference in the cell parameters, as shown in Figure 4 and Table 3.
The X-ray diffraction analysis shows that both, the melted and the sintered Zircaloy, presented α (hexagonal) zirconium structure.

The good properties can be due to the accessibility of effective amino groups in the pores, as well as the suitable pore structure with high specific surface area of 728 m2/g and total pore volume of 0.34 cm3/g.
In future we can expect increasingly complex structures that combine pore sizes with multiple organic or inorganic functional groups that are strategically placed on the internal or external surfaces.

ECE is accomplished by applying an auxiliary anode and electrolyte to the structure surface, and passing direct current between this anode and the reinforcing steel which acts as a cathode [4].
Not as the conventional way of restoration of concrete structures, ECE can not only reduce the chloride ion concentration adjacent to the steel, but also increase the alkalinity around the steel/concrete interface, which will permit repassivation of the reinforcing steel in the high alkalinity.
The use of ultrasound in chemistry offers the synthetic chemist a method of chemical activation which has broad applications and uses equipment which is relatively inexpensive [8].
