Materials Database
The database has collected more than 1303248 full-text documents since 1995, which involves the following aspects: structural materials, metal materials, electric materials, semiconductor materials, superconducting materials, magnetic materials, optical materials, new biological materials, new energy materials, shape memory materials, functional gradient materials, composite materials, nanometer materials, ceramic materials, computational materials, high molecular materials, etc. Generally, materials could be classified into structural materials and functional materials. Structural materials are based on the mechanical properties and are used to make bearing carriers. Functional materials are kind of materials which are formed mainly by utilizing unique physical properties, chemical properties or biological functions of substances. The amounts of data updated per year are 7,000.
