The lightweight materials such as composites are often used for the aerospace structures.
Tail booms are the structures connecting the tail rotor to the fuselage.
The tail booms considered in this study are a semi-monocoque structure consisted of skins and stiffeners.
The vacuum bagging and a moderate heat are used to cure the composite structure.
The laminated composite structure is kept in the machine about 10 hours.

Bilayer artificial muscles (Conducting polymer/tape) are one of the most efficient structures transducing reaction driven small volume variations in the film to large bending movements and macroscopic mechanical energy.

The chemistry of antimony and its natural occurrence in some water resources combine to create a potent, widespread human health risk.
It has been reported that the results of BET measurements of specific surface areas and pore volume for many activated carbons samples suggested that these indicators were excellent indicators of the carbon’s pore structure．The samples with a high iodine number had a large specific surface area and plenty of small micropores (pore diameter > 1.0 nm).

Dielectrophoresis (DEP) is the action of polarizable particles in non-uniform electric field, which depends on the structure of electrode.
In this paper, we present a semi-analytical method, on which the electric field distribution by interdigitated electrode-array with battlement structure is considered.
Interdigitated electrode-array with battlement structure, as one of the most widely used electrode structure [5, 6], can be mainly classified two: the one is interdigitated battlement-electrode-array structure with merlons on contrary position as in Fig. 1; the other is interdigitated battlement-electrode-array structure with merlons on staggered position as in Fig. 2.

This is an unusual and promising approach, as well as modification of materials structure through solvent manipulation, which is a more practical and unexpensive procedure than synthesis of new polymer structures.
Naturally, after undergoing the sulfonation reaction, the polymer structure is modified, causing alterations in organization and packing of polymer chains.
