Patent number: 7410564Abstract: The present invention provides an apparatus and method for identifying and sequencing a biopolymer translocating a nanopore. The apparatus of the present invention provides a first electrode, a second electrode and a potential means for applying a bias ramping potential across the electrodes to produce resonant tunneling of current carriers between the two electrodes. As the bias potential is ramped across the electrodes the increase in tunneling current occurs as the carrier energy sequentially matches the conduction band energies of the translocating biopolymer. This technique allows for real-time identification and sequencing of a biopolymer as the band energy spectra of the individual portions of the bipolymer are recorded, differentiated and identified. A method for identifying the biopolymer is also disclosed.Type: GrantFiled: January 27, 2003Date of Patent: August 12, 2008Assignee: Agilent Technologies, Inc.Inventor: Curt A. Flory

Patent number: 7410567Abstract: The invention relates to Group 1 metal/silica gel compositions comprising silica gel and an alkali metal or an alkali metal alloy. The compositions of the inventions are described as Stage 0, I, II, and III materials. These materials differ in their preparation and chemical reactivity. Each successive stage may be prepared directly using the methods described below or from an earlier stage material. Stage 0 materials may, for example, be prepared using liquid alloys of Na and K which are rapidly absorbed by silica gel (porous SiO2) under isothermal conditions, preferably at or just above room temperature, to form loose black powders that retain much of the reducing ability of the parent metals. When the low melting Group 1 metals are absorbed into the silica gel, a mild exothermic reaction produces Stage I material, loose black powders that are indefinitely stable in dry air. Subsequent heating to 400° C. produces Stage II materials, which are also loose black powders. Further heating above 400° C.Type: GrantFiled: March 28, 2007Date of Patent: August 12, 2008Assignees: SiGNa Chemistry, LLC, Board of Trustees of Michigan State UniversityInventors: Michael Lefenfeld, James L.

Patent number: 7410588Abstract: A process for purifying a liquid from a dissolved solute includes the exposure of the liquid to a material absorbing the liquid in preference to the dissolved solute. The dissolved solute is adsorbed onto the material. Through exposure of the dissolved solute adsorbed on said material to output of an ionization source, solute release from the material occurs. Purification of the liquid to remove the dissolved solute occurs through the release of the liquid from said material separate from the release of the dissolved solute. A system for purifying a liquid from a dissolved solute includes a super absorbent polymer within a housing. A pH source is provided to released purified absorbed liquid portion A via a first outlet in the housing for collecting the released absorbed liquid portion A. An ionization source releases solute absorbed liquid portion B that is collected as a solute rich adsorbed liquid portion B.Type: GrantFiled: September 20, 2007Date of Patent: August 12, 2008Inventor: John Klemic

Patent number: 7410589Abstract: The invention relates to a method of treating manure such that odor from the manure is significantly reduced or eliminated and producing therefrom recyclable water, value-added biosolids and ammonia. Specifically, the manure is combined with lime at high pH. The material is mixed under negative pressure and the basic conditions cause ammonia to be evolved from the manure which is then drawn off and recovered. A coagulating agent is then added which further promotes floc formation within the manure. Following further mixing, flocs are separated from the liquid portion. A struvite-promoting chemical and a coagulant are then added to the liquid portion which causes further floc formation, and the flocs are again separated from the substantially clear liquid. It is of note that as a result of this process, the solids are highly hydrophobic and dry very quickly. It is of further note that solids isolated from either step can be combined and sold, for example, as fertilizer, as discussed below.Type: GrantFiled: July 26, 2002Date of Patent: August 12, 2008Inventor: Gurunathan Lakshman

Patent number: 7410590Abstract: A method for mounting the micro spring structures onto cables or contact structures includes forming a spring island having an “upside-down” stress bias on a first release material layer or directly on a substrate, forming a second release material over at least a portion of the spring island, and then forming a base structure over the second release material layer. The micro spring structure is then transferred in an unreleased state, inverted such that the base structure contacts a surface of a selected apparatus, and then secured (e.g., using solder reflow techniques) such that the micro spring structure becomes attached to the apparatus. The spring structure is then released by etching or otherwise removing the release material layer(s).Type: GrantFiled: December 19, 2003Date of Patent: August 12, 2008Assignee: Palo Alto Research Center IncorporatedInventors: Koenraad F.

Patent number: 7410591Abstract: Provided is a method and system for manufacturing a nano-plate. The method includes depositing two or more types of film around a central core to form a plurality of film layers, each film layer being of a different type than its adjacent layers. Next, the deposited film layers are sectioned to expose a patterned surface. Finally, the patterned surface is then planarized and selectively etched to form a relief pattern which can be used as an imprint stamp.Type: GrantFiled: December 16, 2004Date of Patent: August 12, 2008Assignee: ASML Holding N.V.Inventor: Harry Sewell

Patent number: 7410592Abstract: The stamp (10) for a lithographic process, such as patterning a surface layer, of the invention has a stamp body (5) with at least a first recess (11) formed therein, which recess defines a first aperture (15) in the printing face (3) of the stamp (10). The first recess (11) narrows with increasing distance to the printing face, while any cross-section of the first recess, when perpendicularly projected on the printing face (3), will lie within the aperture (15). The printing face may comprise small (11, 12) and large apertures (13) as well as small surfaces (14) in between apertures, while it is nevertheless able to produce prints which are accurate replicas of the printing face. Even details on a submicron scale can be adequately printed. The stamp (10) can be manufactured by a method which comprises anisotropic etching of a first body to make a mold and replicating the mold in the printing face (3) of the stamp (10).Type: GrantFiled: January 12, 2001Date of Patent: August 12, 2008Assignee: Koninklijke Philips Electronics N.V.Inventor: Martin Hillebrand Blees
