A high-speed double and triple layer rotor design is proposed and different composite materials are tested to achieve the most suitable recipe.
The maximum stress and the density (s/ρ) of composite materials are significantly higher than any metals.
All the proposed composite materials in this work are commercially available [2].

On the other hand, the rigidity of the lateral force is strong for the filled walls, therefore the distributed seismic force is large with low strength for the materials, which cause the serious crack and destroy.
Moreover it includes increasing the setting of the structural column and improving the ratio of the masonry intensity and the mortar materials to guarantee the quality of the masonry and upgrade the reliability of the structural design.
To address the crack of the infill wall of the frame structure, the gap should be left between the infill wall and frame column, which is filled with flexible building materials, to leave enough space for deformation of the frame column.

The specific surface area and pore size are the relative most important roles to influence the application of the mesoporous silica materials.
The mesoporous silica materials with various specific surface areas possess a multiple functions.
Therefore, the preparation of mesoporous silica materials by a convenient strategy has an important realistic significance.
Therefore, using the poly(pseudo)rotaxanes as the template agent may obtain the mesoporous silica materials with diverse specific surface area and pore size.

They also must have good shielding properties to reduce the intensity of the electrostatic fields generated under the garment [13] and anti-static properties to not generate electric charge when come in contact with other materials [14].
If the composite structure is made from materials with different resistivity (conductive-dissipative, conductive-insulating, dissipative-insulating) then the surface covered by the measurement electrodes has a strong influence on the measurement results.
Although the knitted structure is composite and made from two materials with different resistivity, the surface (fabric’s exterior) is unicomposite and is suitable for surface resistivity investigations.

These characteristics are why MNPs are a group of materials widely used as catalysts in the production of biofuels such as biodiesel, bioethanol, bio-oil and hydrogen [3].
These materials are also constituted of fine strongly bound (pre-sintered) particles and low interparticle porosity.
Nanoferrites with a spinel type structure are promising materials for the esterification reaction of soybean oil to produce biodiesel.
