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, 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 |
