Physical and chemical properties of four elements Element Melting point (℃) Density (g·cm-3) Atomic number Atomic radius (10-10m) electronegativity Binding energy (kJ/mol) Crystal structure Cu 1083 8.96 29 0.128 1.90 336 fcc Fe 1535 7.86 26 0.127 1.83 413 α-bcc γ-fcc Mn 1244 7.21 25 0.131 1.55 282 α/δ-bcc γ-fcc Ni 1455 8.908 28 0.124 1.91 428 fcc As seen from Table 1, Fe has the highest melting point and much larger binding energy than that of Cu and Mn, indicating that Fe diffusion activation energy is far above that of Cu and Mn.

But the lack of effective methods to prepare fully dense ceramics with grain sizes less than 100nm dramatically limit the progress of exploring new properties of such fine-structured materials.

Natural polymer chitosan has a long chain structure, most of which fill of free -NH2, and due to its lone pair of electrons, it presents weakly alkaline amino and can lead to the combination of a proton in solution which makes chitosan become positively charged polyelectrolyte .
