Conclusion Original steel materials are replaced by magnesium alloy, and the weight of main frame of electric scooter is only 1.8 kg and reduces by 60%, which achieves a substantial decrease.
While replacing material, the main frame has been redesigned by using finite element analysis.

Commercial synthetic calcium phosphates have been used as bone graft materials.
Materials and Methods Commercial powder, calcium deficient apatite (Merck, Darmstadt, Germany), was used to produce discs, diameter 13mm and height 1mm, by uniaxially pressing under a compressive stress of 216 MPa.
Although all cells in both materials (β-TCP-HI and β-TCP-PB) presented large amounts of filopodia and vesicular structures on cells surface, the results suggest that only β-TCP-HI promoted the cells differentiation due to deposits of delivered extracellular matrix.

Therefore, developing fast soil stabilizing materials has become a critical issue in air strip construction.
Traditionally, a variety of hydration products or polymer are formed after the inorganic combined materials (such as the cement and lime) react with water in soil pores to improve the structural strength of the soil.
Compared with traditional inorganic combined materials, the soil stabilizer changes the surface features of the soil particles after the surfactant takes translucent, and odorless.
However, in order to ensure the reliability of use of con-aid stabilizers in airstrip pavement, we will conduct more in-depth studies by comparing the con-aid stabilizers and other soil reinforcement materials.
