|Sub-fields of materials science||Definitions|
|1. Nanotechnology||a) the study of the way by which atoms in a solid fill space, the defects associated with crystal structures such as grain boundaries and dislocations, and the characterization of these structures and their relation to physical properties|
|2. Microtechnology||b) materials that are derived from and/or used with biological systems|
|3. Crystallography||c) materials such as semiconductors used to create integrated circuits, storage media, sensors, and other devices|
|4. Metallurgy||d) interactions and structures between solid-gas solid-liquid or solid-solid interfaces.|
|5. Biomaterials||e) the study of materials and processes and their interaction Match the sub-fields of material science with the definitions., allowing microfabrication of structures of micrometric dimensions, such as MicroElectroMechanical Systems (MEMS).|
|6. Electronic and magnetic materials||f) the study of the microstructures of high-temperature materials and refractories, including structural ceramics such as RCC, polycrystalline silicon carbide and transformation toughened ceramics|
|7. Tribology||g) the study of metals and their alloys, including their extraction, microstructure and processing|
|8) Surface science/Catalysis||h) the study of the wear of materials due to friction and other factors.|
|9) Ceramography||i)it is the creation and the study of materials whose structural properties are defined by their dimensions being less one hundred nanometers|
