Materials Science and Materials Chemistry

Nanostructures deal with objects and structures that are in the 1-100 nm range.In many materials, atoms or molecules cluster together to form objects at the nanoscale. This leads to interesting electromagnetic, optical and mechanical properties. The term 'nanostructure' is often used when referring to magnetic technology and also applied in case of advanced materials. Microstructure is defined as the structure of a prepared surface or thin foil of material as revealed by a microscope  above 25× magnification. It deals with objects from 100 nm to a few cm. Most of the traditional materials (such as metals and ceramics) are micro structured. Macrostructure is the appearance of a material in the scale millimetres to meters—it is the structure of the material as seen with the naked eye.
