Advanced Nano Materials
Nano materials refers to the matter whose length scale, in any dimension, is approximately 1 to 100 nanometers. It can be metals, ceramics, polymeric materials, or composite materials. The processing, structure and properties of materials with grain size in the tens to several hundreds of nanometer range are research areas of considerable interest over the past years. On nanoscale, some physical and chemical material properties can differ significantly from those of the bulk structured materials of the same composition. the theoretical strength of nanomaterials can be reached or quantum effects may appear; crystals in the nanometer scale have a low melting point and reduced lattice constants, since the number of surface atoms or ions becomes a significant fraction of the total number of atoms or ions and the surface energy plays a significant role in the thermal stability.
