KGM and Collagen II were selected as the main raw materials and ammonia served as the crosslinking agent to prepare the porous KGM / COLII composite cartilage scaffolds by blending method and freeze-drying method.
Numerous studies have shown that KGM can serve as skin scaffold materials, the cartilage scaffold materials and other scaffold materials of tissue engineering [9, 10-12].

Materials and Methods Zinc acetate (Merck) and antimony trichloride (Alfa Aesar) were dissolved in an aqueous media and the solution was mixed altogether and stirred magnetically for 30 mins thereafter a white precipitate occurs that was filtered, washed with double distilled water for several times to remove the unreacted impurities and dried in hot air oven at 100 °C for 3 h.
The electrochemical capacitor characteristics of the nafion indicate that it is as a potential electrode material for supercapacitors.

Abstract: Composite materials are now a day most frequently used materials in aerospace structures.
They also increase weight of the system tat may nullify the advantages we get from composite materials.
These composite materials are mostly carbon fibre reinforced composites [1,4,6-8,9,10] and fibreglass reinforced composites[2,11].
There are number of studies on mechanically fastened composite materials [4,6-10,14,15].
The basic materials used to prepare joints of composite material were carbon gibers,glass fiber, epoxy, polyvinyl alcohol, wax polish, nut and bolt.
