摘要： The present invention relates to a method for preparing photoluminescent silicon nanoparticles having uniformly hydrogen-terminated surfaces that are essentially free of residual oxygen. The present invention also relates to a method of preparing a blue-emitting photoluminescent silicon nanoparticle. The present invention further relates to a composition that includes a photoluminescent silicon nanoparticle having a surface that is uniformly hydrogen-terminated and essentially free of residual oxygen. The present invention also relates to a composition including a photoluminescent silicon nanoparticle having a surface that is uniformly coated with an organic layer and essentially free of residual oxygen. The present invention additionally relates to a composition including a photoluminescent silicon nanoparticle stably dispersed in an organic solvent and having a surface that is uniformly coated with an organic layer and essentially free of residual oxygen.

摘要： Olefin polymerization catalysts or catalyst systems comprising a mixture, contact product, reaction product or complex comprising as elements or components: (A) at least one metallocene pre-catalyst compound or polymerization active metallocene compound; (B) at least one titanium containing metallocene compound; and when (A) is a metallocene pre-catalyst compound, (C) at least one activator; provided however: (I) the titanium-containing metallocene compound is inactive or substantially inactive for the polymerization of olefins prior to or concurrently with the use of the catalyst system for olefin polymerization. Also disclosed are processes for producing the catalyst system and polyolefins having desirable combinations of properties, including melt index and molecular weight distribution, which properties are particularly desirable for the manufacture of polyolefin film products, especially LLDPE film A preferred catalyst comprises a zirconium or hafnium metal containing metallocene, an inactivated titanocene and a SiO2 support carrier.
