Disclosed herein are coated beads made of a primary matrix material and containing a population of quantum dot nanoparticles. Each bead has a multi-layer surface coating. The layers can be two or more distinct surface coating materials. The surface coating materials may be inorganic materials and/or polymeric materials. A method of preparing such particles is also described. The coated beads are useful for composite materials for applications such as light-emitting devices.

Multi-layer-coated quantum dot beads

Methods are provided to form and stabilize high-&#x3ba; dielectric films by chemical phase deposition processes using metal-source precursors and cerium-based &#x3b2;-diketonate precursors according to Formula I: Ce(L)x (Formula I) wherein: L is a &#x3b2;-diketonate; and x is 3 or 4. Further provided are methods of improving high-&#x3ba; gate property of semiconductor devices by using cerium precursors according to Formula I. High-&#x3ba; dielectric films are also provided comprising hafnium oxide, titanium oxide or mixtures thereof, and further containing a permittivity maintaining or increasing amount of cerium atoms.

Methods of producing high-K dielectric films using cerium-based precursors

The present invention relates to a process for fabricating a quadrupole mass spectrometer (QMS) component, to a monolithic quadrupole mass spectrometer or a component thereof, to a quadrupole mass filter (QMF) or quadrupole ion trap (QIT) capable of generating a hyperbolic electric field and to a modular quadrupole mass spectrometer (QMS) assembly.

Process

The present invention relates to a process for fabricating a composite functional body/substrate, either by melting with an energy beam or by spin coating. The functional material is preferably a piezoelectric material (PVDF). The energy beam is preferably a laser beam.
