EAEs have demonstrated an estimated 0.4 J/g specific energy density, compared with around 0.1 J/g for advanced single crystal ceramics and around 0.04 J/g for electromagnetic materials.
EAEs have many advantages that distinguish them from other energy-conversion materials, such as, lighter – low density, high performance, multifunctional polymers; cheaper – inexpensive materials, fewer parts, no precision machining; quieter – high energy density and compliance of polymers allows quiet primarily sub-acoustic operation with few moving parts; softer – rubbery materials are impedance matched to large motions (e.g. human motion, engines); versatile – polymers are scale-invariant, and systems can be made in variety of form factors (conformal, elongated, etc.).

They used burnt clay volcanic pumices, fly ashes and mineral slags as raw materials with the effect of alkali activator and the use of appropriate technology to form a compact high-strength material dominated by aluminum oxygen tetrahedron and silicon-oxygen tetrahedron with amorphous and quasicrystalline characteristics of three-dimensional network.
We used hydrothermal synthesis method to prepare zeolite enhanced geopolymer material in the research and static experiment to study the adsorption performances and mechanisms of materials on Sr2+, Co2+ and Cs+, for the theological basis of solid chemical waste, toxic heavy metal ions and radioactive nuclear waste [1] adsorption. 2 Materials and experiments 2.1 Raw materials and preparation We used three major materials, metakaolin, which obtained from Beihai Yanzhou mining kaolin Co., Ltd.; fly ash, which was from Tiandong power plant in China, Guangxi; sodium hydroxide, which containing sodium hydroxide 96% and bought from the market with analytical grade.

Similarly, our experiment was developed for cylindrical samples of trabecular bone exposed to sinusoidally-variable loads; however a stepwise loads were applied, which has not been applied in bone experiments, but is commonly used when investigating other materials and structures [11, 12, 13, 14, 15].
