Study on fundamental relationship between physical properties and the material dimensions on the
nanometer scale forM.S. the basics of nanoscience.1 The physical dimension of a material is along the X, Y
and Z axes. Nanomaterials are defined as materials with at least one of the above mentioned dimensions
in the range of 1-100 nanometers approximately.1 Nanoparticles are objects with all three external
