ABSTRACT
The word “nano” comes from the Latin word nanus meaning dwarf. Nanomaterials attract more and more interest because of the unique optical, magnetic, electrical, and mechanical properties that exist on that scale. These special properties may have a significant impact in electronics, medicine, and other fields. Some nanomaterials with different shapes, including gold, carbon, metals, meta-oxides, and alloy. The physical and chemical properties of nanomaterials at the nano-scale are much different from those at bulk size, which is due to the nanometer size of the materials resulting in a large fraction of surface atoms, high surface energy, spatial confinement, and reduced imperfections. The scale of the single-crystal iron particles is nanometer; it is hard to measure the elastic parameters of the particles by using the conventional way. The Young’s modulus of the single-crystal iron particles was obtained from the contact reaction forces by using the finite element method.
