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
