Abstract: A collection of silicon oxide nanoparticles have an average diameter from about 5 nm to about 100 nm. The collection of silicon oxide nanoparticles effectively include no particles with a diameter greater than about four times the average diameter. The particles generally have a spherical morphology. Methods for producing the nanoparticles involve laser pyrolysis. The silicon oxide nanoparticles are effective for the production of improved polishing compositions including compositions useful for chemical-mechanical polishing.

Abstract: Nanoscale particles, particle coatings/particle arrays and corresponding consolidated materials are described based on an ability to vary the composition involving a wide range of metal and/or metalloid elements and corresponding compositions. In particular, metalloid oxides and metal-metalloid compositions are described in the form of improved nanoscale particles and coatings formed from the nanoscale particles. Compositions comprising rare earth metals and dopants/additives with rare earth metals are described. Complex compositions with a range of host compositions and dopants/additives can be formed using the approaches described herein. The particle coating can take the form of particle arrays that range from collections of disbursable primary particles to fused networks of primary particles forming channels that reflect the nanoscale of the primary particles. Suitable materials for optical applications are described along with some optical devices of interest.

Abstract: Inorganic particle/polymer composites are described that involve chemical bonding between the elements of the composite. In some embodiments, the composite composition includes a polymer having side groups chemically bonded to inorganic particles. Furthermore, the composite composition can include chemically bonded inorganic particles and ordered polymers. Various electrical, optical and electro-optical devices can be formed from the composites.

Abstract: Vanadium oxide nanoparticles with different vanadium oxidation states and different crystal structures. The particles have a narrow distribution of particle diameters and unique properties that result from their small size and correspondingly large surface area. The particles are produced by laser pyrolysis, and can be further treated to change their properties, without destroying their nanoscale size. The stoichiometry and crystal structure can be varied by initial heating under mild conditions. The materials may be used as cathode active materials in high energy density batteries.

Abstract: Light reactive deposition uses an intense light beam (684) to form particles that are directly coated onto a substrate (680) surface. In some embodiments, a coating apparatus comprising a noncircular reactant inlet (682), optical elements forming a light path (684), a first substrate (680), and a motor connected to the apparatus. The reactant inlet (682) defines a reaction zone with a product stream path continuing from the reaction zone. The substrate (680) intersects the product stream path. Also, operation of the motor moves the first substrate (680) relative to the product stream. Various broad methods are described for using light driven chemical reactions to produce efficiently highly uniform coatings.
