These methods are useful for synthesizing nanoparticles of metals, semiconductors, ceramics or any other material class where the precursors are either in liquid form or can be dissolved or suspended in a suitable liquid. Methods of feeding nebulized droplets and central gas into a radio frequency plasma torch and apparatus for generating nanoparticles are also described. | 12-03-2009 |
20100200808 | NANOSCALE PHOSPHOR PARTICLES WITH HIGH QUANTUM EFFICIENCY AND METHOD FOR SYNTHESIZING THE SAME - Described herein are batches of nanoscale phosphor particles having an average particle size of less than about 200 nm and an average internal quantum efficiency of at least 40%. The batches of nanoscale phosphor particles can be substantially free of impurities. Also described herein are methods of manufacturing the nanoscale phosphor particles by passing phosphor particles through a reactive field to thereby dissociate them into elements and then synthesizing nanoscale phosphor particles by nucleating the elements and quenching the resulting particles. | 08-12-2010 |
20120141599 | Regulation Of Bone Growth Using Zeolite In Combination With Bone Graft Substitutes - Medical implants such as bone graft substitutes that include one or more cations are delivered in a local environment to promote osteogenesis.
