To carry out drying of printing ink with the use of Nano sized high-temperature dryness steam. Nano sized high-temperature dryness steam being clustered on Nano oder is generated and jetted to the print side of printed material so that the Nano sized high-temperature dryness steam imparts intramolecular vibrational energy to ink of the print side. Consequently, the Nano sized high-temperature dryness steam being clustered on Nano oder not only passes through fiber pores in the printed material but also collides with the ink of the print side. The Nano sized high-temperature dryness steam having collided with the ink of the print side imparts thermally excited energy as intramolecular vibrational energy to the ink containing polar molecules. The ink is dried by the intramolecular energy.

A nanostructured pn junction light-emitting diode is fabricated from a semi-conducting substrate doped by a first dopant and covered by a dielectric thin layer. An amorphous thin film formed by a semi-conducting material doped by a second dopant of opposite type to that of the first dopant is then deposited on the surface of the dielectric thin layer.

Nanoscale chemicals based on polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) are taught as lubricants, mold release agents, and as additives to control the viscosity, lubrication, wear, and thermal properties of conventional lubricous materials. The precisely defined nanoscopic dimensions of POSS materials enable viscosity, miscibility, and thermal properties to be (increased) or reduced (decreased) as desired. A key feature to the successful tailoring of properties is the inherent thermal and chemical stability of the POSS/POS nanostructure and the ability to control its topology and chemical potential to match that of surfaces and other materials.
