Nano Structural Materials

Nanostructured Materials (NsM) are materials with a microstructure and the characteristic length scale of which is on the order of 1 to 100 nm. NsM synthesized by supramolecular chemistry are examples of NsM in thermodynamic equilibrium. Two key factors cause the properties of nanomaterials to be special: their quantum effects and their structure.  Their tiny structure means they have a greater relative surface area than other materials and this can alter or improve properties such as strength and electrical characteristics or reactivity. The properties of NsM deviate from those of single crystals (or coarse-grained polycrystals) and/or glasses with the same average chemical composition. This deviation results from the reduced size and/or dimensionality of the nanometer-sized crystallites as well as from the numerous interfaces between adjacent crystallites
