Patent number: 7112449Abstract: Combinatorial synthesis methods obtain a plurality of compositions having materially different characteristics using an apparatus having a plurality of collectors. A first quantity of fluid reactants are reacted to form a first quantity of product composition. Following completion of the collection of the first quantity of product composition, a second quantity of fluid reactants are reacted to form a second quantity of product composition, the second quantity of product composition being material different from the first quantity of product composition. An apparatus includes a nozzle connected to a reactant source and a plurality of collectors. The nozzle and plurality of collectors move relative to each other such that a collector can be selectively placed to receive a fluid stream emanating from the nozzle. The plurality of product compositions can be evaluated to determine their suitability for various applications.Type: GrantFiled: April 25, 2000Date of Patent: September 26, 2006Assignee: NanoGram CorporationInventors: Xiangxin Bi, Sujeet Kumar, Craig R.

Patent number: 6723435Abstract: Optical fiber preforms can comprise a glass preform structure with an inner cavity. A powder can be placed within the inner cavity having an average primary particle size of less than about one micron. The powder can be in the form of an unagglomerated particles or a powder coating with a degree of agglomeration or hard fusing ranging from none to significant amounts as long as the primary particles are visible in a micrograph. Powders can be placed within a preform structure by forming a slurry with a dispersion of submicron/nanoscale particles within a cavity within the prefrom. In other embodiments, a powder coating is formed within a preform structure by depositing the powder coating directly from a reaction product stream. The formation of the powder coating can be formed within the reaction chamber or outside of the reaction chamber by flowing the product particle stream through a conduit leading to the preform structure. In additional embodiments, a powder coating is placed on an insert, e.g.Type: GrantFiled: August 28, 2002Date of Patent: April 20, 2004Assignee: NanoGram CorporationInventors: Craig R.

Patent number: 5368667Abstract: A device having a thin ceramic layer therein, is made by preparing a mixture of ceramic particles, a binder, and a plasticizer, and forming the mixture into a ceramic layer. A second layer is placed adjacent to the ceramic layer to form a composite layered structure. The thickness of the composite layered structure is reduced, preferably by rolling, until the ceramic layer portion of the composite layered structure has a preselected small thickness. If desired, the thickness of the ceramic layer can be reduced to an arbitrarily small value by stacking the reduced composite layered structures (or one of the layered structures with another structure) and repeating the reducing operation on the stack. The ceramic layer having the preselected thickness is assembled into a device. Devices that can be prepared by this approach include, for example, multilayer capacitors, solid oxide fuel cells, and solid-electrolyte electrochemical storage cells.Type: GrantFiled: January 29, 1993Date of Patent: November 29, 1994Assignee: AlliedSignal Inc.Inventors: Nguyen Q.
