Material Processing Engineering Laboratory

Developing new materials by nanotechnologies

In the cases where the component materials are made tiny (i.e., nanoparticles consisting of about 200 atoms), the melting point is lowered to one-fifth of their larger version. For instance, the melting point can be lowered to 200°C from 1000°C in these cases. Hence, taking advantage of the wonders seen in nano-sized components can lead to the creation of materials that could not possibly be made before. We succeeded in developing materials by blending with precision the materials that do not blend, such as water and oil. Moreover, our laboratory is developing new materials by using nanotechnologies.
