  • Patent number: 8021523
    Abstract: Disclosed herein is an electrostatic fluid filtration system suitable for removing sub micron insoluble contaminants known to cause varnish from fluids such as dielectric fluids. The electrostatic fluid filtration system is configured to remove both water and other contaminants from a target fluid (e.g. a dielectric fluid) and comprises a cabinet, a computer control unit, and one or more substantially cylindrical filtration units, including at least one of a water filtration unit and an electrostatic contaminant filtration unit. In the contaminant filtration unit, the target fluid flows radially through the filtration media that is positioned between the electrode plates in a generally horizontal flow pattern. This forces the target fluid to traverse multiple energy fields in a serpentine fashion and in a single pass through the contaminant filtration unit. After flowing through each layer of the filtration media, the target fluid is discharged from the electrostatic contaminant filtration unit.

    Abstract: The present invention generally relates to mass spectrometry and related techniques, and in some cases, to determining single species using mass spectrometry. In certain instances, polymers such as DNA or RNA can also be sequenced. Certain embodiments of the invention relate to passing a polymer, such as DNA, RNA, a protein, a polypeptide, a polysaccharide, etc., through a pore and cleaving the polymer in sequence. For instance, the polymer may be cleaved using a laser or an electric field. In some embodiments, a property of at least one subunit of a polymer is determined using mass spectrometry. In some embodiments, a single ion (which may be a subunit of a polymer, or an ion based on another species) can be isolated in a mass spectrometer and a signal generated from the single ion.

The critical elasticity is enhanced to the level of the dragline spider silk. The provided enhanced silk protein material has the same protein primary structure, fiber diameter and length of the customary silk. The method of formation offers the following advantages in comparison to other methods available in the prior art. Industrial scale production can be readily and cost-effectively achieved, given the wide-range availability of silkworms. The provided method relies largely on the present standard production processes of silkworm silk, and hence a low level of investment is required.

    Abstract: The present invention provides a plasma method for conversion of carbon dioxide into useful organic products. In this method, carbon dioxide and counterpart molecules are mixed in a reaction chamber and the plasma excitation is utilized to trigger chemical reactions. Depending on the magnitude of the input power and molecular structures of counterparts, the final product may be polymers, oligomers, or low molecular weight small molecules. The conversion yields of carbon dioxide and chemical structures of the resulting products are strongly dependent on the selection of the counterpart molecules. Through this plasma technology, carbon dioxide is converted into useful materials such as plastics or fuels. This method is not only used to remedy global warming but also to produce new materials and energy.

  • Patent number: 7510632
    Abstract: A dielectric liquid having entrained bubbles of gas or vapor is subjected to an electric field applied between spaced electrodes (112, 116) which generates microdischarges (and thus plasma) within the bubbles, allowing modification of the properties of the dielectric liquid. The invention is particularly useful for treating hydrocarbon liquids such as gasolines and other liquid hydrocarbon fuels, which have extremely low dielectric constants. Generating microdischarges within bubbles in such fuels can create compounds useful for higher combustion efficiency and/or lower emissions in internal combustion engines. The invention may be directly implemented in an engine's fuel line upstream from the combustion chamber (e.g., immediately prior to a fuel injector), thereby allowing the invention to be usefully implemented for fuel treatment prior to combustion.

  • Patent number: 7507317
    Abstract: This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with the properties of the reacting components in the bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of 100 kHz to 200 MHz or greater are suitable for the enhancement of the reactions. An electric field of any shape having Fourier components that when applied to a chemical process exhibits growth in the real part of conductivity relative to the low frequency value is of particular importance.

The device is immersed in the water flowing across the membranes and is operated continuously at very high voltages, preferably greater than 30,000 volts DC. The charge on the wetted surface of the suspended particles is altered by the electrostatic field so generated and is found to reduce biofilm formation, thereby materially enhancing the performance of the membrane-separation system.

  • Patent number: 6803228
    Abstract: The present invention relates to a method to produce a biochip and to a biochip, said biochip being composed particularly of biological probes grafted onto a conductive polymer. The method according to the invention comprises the following steps: a) structuring of a substrate so as to obtain on said substrate microtroughs comprising in their base a layer of a material capable of initiating and promoting the adhesion onto said layer of a film of a pyrrole and functionalised pyrrole copolymer by electropolymerisation, b) collective electropolymerisation, so as to form an electropolymerised film of a pyrrole and functionalised pyrrole copolymer on the base of said microtroughs, c) direct or indirect fixation of functionalised oligonucleotides by microdeposition or a liquid jet printing technique.

  • Patent number: 6783633
    Abstract: This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with the properties of the reacting components in the bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of 100 kHz to 200 MHz or greater are suitable for the enhancement of the reactions. An electric field of any shape having Fourier components that when applied to a chemical process exhibits growth in the real part of conductivity relative to the low frequency value is of particular importance.

  • Patent number: 6673322
    Abstract: A process for the production of a clean burning combustible gas by flowing a liquid through an electric arc. The electrodes have several configurations. The invention prevents the production of carbon dioxide in the gas thereby reducing its presence when combusted and exhausted to about half that associated with gasoline exhaust; increases the cost efficiency of the process by eliminating secondary chemical reactions; and increases the life of the electrodes. The chemical structure of the combustible gas is composed of stable magnetically bonded clusters of conventional molecules and atoms that are fully detectable via peaks in conventional mass spectrometric detectors, yet such clusters remain unidentifiable by the computer search among all known molecules, and have no infrared signature other than those of the conventional molecules constituting the clusters. The liquid which is flown through the arc also acquires the chemical structure of magnetically bonded clusters.
