Nanophase Announces Patent Application for Composite Nanoparticles
Nanophase Technologies Corporation (Romeoville, IL, USA) has just announced that it has filed a US patent application detailing a novel composite nanoparticle structure having a core-shell structure exhibiting improved properties over single constituent nanoparticles. This new class of nanoparticles offers improved performance and value in a wide range of applications, ranging from catalysts to electromagnetic materials and chemically passive materials.The patent application also details carefully controlled compositions, morphologies and methods of manufacturing nanoparticle composites that provide surprisingly superior oxygen storage capacity for catalytic reactions. This storage capacity is retained during reaction cycling and enables the catalyst material to be effective at temperatures greater than currently reported application temperatures because the unique composite morphology prevents particle size growth.
