  • Publication number: 20110171239
    Abstract: This invention provides for compositions, methods and devices for rapidly converting silk fibroin solution into a silk fibroin gel using direct application of voltage, in a process called electrogelation. The silk fibroin gel may be reversibly converted back to liquid form by applying reverse voltage or may be converted further to ?-sheet structure by applying shear force or other treatments. The electrogelated silk may be used as an extracted bulk gel, spray or stream of gel for processing into materials or devices, or may be used as silk gel coating to devices. Active agents may be embedded in the silk gel for various medical applications. This invention also provides for methods and compositions for preparing adhesive silk pH-gels. For example, the method comprises reducing pH level of a silk fibroin solution to increase the bulk or local proton concentration of the silk fibroin solution, thereby forming adhesive silk gels.

  • Patent number: 7611619
    Abstract: The invention provides a simple and convenient strategy for reducing the dimensions of organic micro- and nanostructures on metal surfaces. By varying electrochemical desorption conditions, organic structures patterned by Dip-Pen Nanolithography or any of the micro-contact printing procedures can be gradually desorbed in a controlled fashion. The electrochemical desorption is initiated at the exterior of the feature and moves inward as a function of time. The desorption process and adsorbate desorption are modified and controlled as a function of substrate morphology, adsorbate head and tail groups, and electrolyte solvent and salt. Different nanostructures made of different adsorbates can be miniaturized based upon judicious selection of adsorbate and supporting electrolyte.

  • Patent number: 7192556
    Abstract: The invention relates to a flow cell, a method for separating carrier-free radionuclides from a liquid or liquefiable target material, and the radiochemical reaction thereof. According to prior art, flow cells are known which require reaction volumes corresponding to the volume of the target material in order to carry out the desired reactions. The inventive flow cell (1) and method enable the reaction volume, and thus the quantity of starting material, to be reduced by a multiple by reducing the cylinder volume (=reaction volume). As the radioactively marked product is present in very small quantities (picomole to nanomole), the HPL-chromatographic separation of the non-reacted starting material is significantly improved. The economic efficiency of the method is increased due to the fact that small quantities of starting material can be used.

  • Patent number: 6984305
    Abstract: A process for the production of hydrogen from anaerobically decomposed organic materials by applying an electric potential to the anaerobically decomposed organic materials, including landfill materials and sewage, to form hydrogen, and for decreasing the time required to treat these anaerobically decomposed organic materials. The organic materials decompose to volatile acids such as acetic acid, which may be hydrolyzed by electric current to form hydrogen. The process may be continuously run in sewage digestion tanks with the continuous feed of sewage, at landfill sites, or at any site having a supply of anaerobically decomposed or decomposable organic materials.

  • Patent number: 6984303
    Abstract: An electrochemical process for the preparation of water-soluble colorants, particularly triphenylmethane colorants and other water soluble technical dyes, is disclosed. In this process, the anode in the electrochemical cell comprises an open pore carbon material having specific void volume and surface area characteristics. A preferred electrode material is a carbon felt pad, preferably between about 1/16 inch and ¼ inch in thickness. This process provides faster reaction rates than electrochemical processes using standard electrodes, as well as higher yields compared to processes using chemical oxidizing agents.

  • Patent number: 6896790
    Abstract: An apparatus for oxidatively destructing a trace injurious substance includes a structure with anodes, each integrally provided with an electrically conductive oxide on their surface and made of a metal. A partition made of a porous ceramic or resin is provided between the anodes and surrounded by cathodes made of a metal plate having inner walls on both sides to which a noble metal is fused, such that at least two chambers with spaces are formed in a plane symmetrical arrangement to provide an apparatus for oxidatively destructing a trace injurious substance contained in polluted water. The apparatus has a rectangular wave discharging device for applying an electric field to the spaces, such that polluted water flows through the inner space of one of the chambers and is subjected to the irradiation of an electric field, and the supernatant thereafter flows through the inner space of the other chamber and is subjected to the irradiation of an electric field.

  • Publication number: 20040256247
    Abstract: A mediated electrochemical oxidation process is used to treat and destroy organic waste materials. The materials are introduced into an apparatus containing an electrolyte having the oxidized form of one or more redox couples. The oxidized couples oxidize the organic waste materials and are converted into their reduced form. The reduced forms are reoxidized by electrochemical anodic oxidation in the anode compartment of an electrochemical cell or reaction with the oxidized form of other redox couples. The redox cycle continues until the desired degree of oxidation is reached. The process takes place at temperatures between ambient and approximately 100° C., to avoid the formation of dioxins or furans. The oxidation process may be enhanced by the addition of reaction enhancements, such as: ultrasonic energy and/or ultraviolet radiation.

  • Patent number: 6827832
    Abstract: The invention disclosed relates to an electrochemical process for decreasing high levels of organic contaminants in metal plating baths. The process involves breaking down the organic contaminants in an electrochemical cell by electrochemical oxidation. The electrochemical cell includes an anode comprising an active material which is stable at low (acid) pH and at the high electrical potential required to break down the organic contaminants by oxidation. Typical examples of such anodes include a valve metal substrate coated with doped tin dioxide, lead dioxide, or platinum-based materials, the latter in some instances being coated on a high surface area valve metal substrate.

  • Publication number: 20040232007
    Abstract: A mediated electrochemical oxidation process is used to treat, oxidize and destroy food waste materials, such as manure, biological residue, hay, straw, animal byproducts, bones, horns, blood, biological items, pathological waste and combined waste. Food waste is introduced into an apparatus for contacting the waste with an electrolyte containing the oxidized form of one or more reversible redox couples, at least one of which is produced by anodic oxidation in an electrochemical cell. The oxidized species of the redox couples oxidize the organic waste molecules and are themselves converted to their reduced form, whereupon they are reoxidized by either of the aforementioned mechanisms and the redox cycle continues until all oxidizable waste species, including intermediate reaction products, have undergone the desired degree of oxidation. The process takes place at temperatures between zero degrees centigrade and below the boiling point of the electrolyte.
