摘要:A process for the rapid synthesis of metal oxide nanoparticles at low temperatures and methods which facilitate the fabrication of long metal oxide nanowires. The method is based on treatment of metals with oxygen plasma. Using oxygen plasma at low temperatures allows for rapid growth unlike other synthesis methods where nanomaterials take a long time to grow. Density of neutral oxygen atoms in plasma is a controlling factor for the yield of nanowires. The oxygen atom density window differs for different materials. By selecting the optimal oxygen atom density for various materials the yield can be maximized for nanowire synthesis of the metal.

标题:Apparatus and method for continuous synthesis of vanadium oxide
发明人：MALLINSON STEVEN M; MCALEAVEY MICHAEL E
摘要:In a method for the continuous synthesis of vanadium oxide from ammonium metavanadate, ammonium metavanadate is fed to the interior of a dryer apparatus through an inlet opening. The interior of the apparatus is maintained at a temperature of approximately 440° C. and an inert carrier gas flows through the interior of the apparatus. The ammonium metavanadate is conveyed through the interior of the dryer apparatus on a conveyer to an outlet opening over a period of approximately two hours, during which period the ammonium metavanadate is continuously agitated so that it is uniformly exposed to heat and to the carrier gas, thereby synthesizing homogeneous vanadium oxide. The vanadium oxide is continuously removed from the apparatus.
