Plasma is generated in a vicinity of or in a manner to make contact with a liquid whose pH value is adjusted to become 4.8 or lower, more preferably 4.5 or lower. The plasma is generated in an atmospheric gas containing nitrogen, e.g., in the air. Superoxide anion radicals (O2?.) that are generated by the plasma react with protons (H+) in the liquid to form hydroperoxy radicals (HOO.). Further, nitrogen and oxygen included in the air are combined together by the action of plasma to form nitrogen oxide such as nitric oxide (NO.). The nitric oxide (NO.) combines with the hydroperoxy radicals (HOO.) to become peroxynitrite (ONOOH(ONOO?)) having a high microbiocidal activity.

  • Patent number: 8475645
    Abstract: A cooling water circulation apparatus is capable of limiting attachment of microorganisms and scale in an environmentally friendly manner. An electrolytic device 10 is provided on a cooling water circulation route R1. In the arrangement, mineral contents such as calcium ions and magnesium ions contained in cooling water W are deposited as scale S on an electrode 12A or 12B in an electrolytic step, thereby enabling the mineral contents to be removed from the cooling water W. Even if the hardness of the cooling water W is increased by evaporation of the water with elapse of time, the hardness can be reduced by the electrolytic processing. Thus, the deposition of the scale S in the circulation route R1 can be reduced. Further, the scale S deposited on the electrode 12A or 12B can be easily separated by operating while reversing the polarities of the electrodes 12A and 12B at predetermined time intervals.

  • Patent number: 8152989
    Abstract: A system and process for treating ballast water within an ocean going vessel by generating hypochlorite for treating the ballast water. The system comprises one or more hypochlorite electrolytic cells in fluid communication with ballast water. The total organic carbon content of the ballast water is ascertained and the amount of hypochlorite generated is modulated in response to the total organic carbon content of the ballast water. In one embodiment the system comprises a total organic carbon analyzer for measuring total organic carbon content. In one embodiment of the process of the invention, hypochlorite production is modulated so that the residual halogen-containing oxidizing agent is maintained in the ballast water. In another embodiment of the process, hypochlorite production is modulated to maintain a weight ratio of hypochlorite to total organic carbon in the ballast water ranging from about 1.0 to about 3.0.

  • Patent number: 8133379
    Abstract: The invention relates to a method for producing at least one hydrophilic area on a hydrophobic substrate. The method consists in performing an electrochemical reduction of the surface under the following conditions: the reduction is performed in an electrochemical cell which contains an electrolytic solution containing a compound that is a precursor of a reducing agent, said compound having a standard potential of less than ?2.7 V relative to the saturated calomel electrode (SCE); the reducing electrode is placed relative to the substrate surface to be treated such that said surface is facing the surface of the electrode, which is the image of the area to be reduced; the reducing electrode is subjected to the formation potential of the reducing agent.

  • Patent number: 8101061
    Abstract: In some embodiments, the present invention is directed to processes for the combination of injecting charge in a material electrochemically via non-faradaic (double-layer) charging, and retaining this charge and associated desirable properties changes when the electrolyte is removed. The present invention is also directed to compositions and applications using material property changes that are induced electrochemically by double-layer charging and retained during subsequent electrolyte removal. In some embodiments, the present invention provides reversible processes for electrochemically injecting charge into material that is not in direct contact with an electrolyte. Additionally, in some embodiments, the present invention is directed to devices and other material applications that use properties changes resulting from reversible electrochemical charge injection in the absence of an electrolyte.

  • Publication number: 20110303554
    Abstract: An enzyme electrode that enables rapid degradation of bisphenol-A (BPA) in a contaminated sample and/or monitoring of BPA concentration in a contaminated sample. The enzyme electrode includes a working electrode having one or more selected enzymes that are capable of degrading BPA linked to the working electrode. The selected enzymes linked to the working electrode are capable of degrading BPA at an enhanced rate in response to an applied voltage. The electrode can be used to monitor BPA concentration in a contaminated sample by measuring current flow through the electrode in response to an applied voltage.

  • 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.
