The singularity-based configuration described here includes: an anode electrode; a cathode electrode; and an insulator disposed between the anode electrode and the cathode electrode. The singularity-based electrode design concept refers to electrodes in which the anode and cathode are adjacent to each other, placed essentially co-planar and are separated by an insulator. The essentially co-planar anode/insulator/cathode configuration bound one surface of the volume of interest and produce desired electric fields locally, i.e., in the vicinity of the interface between the anode and cathode. In an ideal configuration, the interface dimension between the anode and the cathode tends to zero and becomes a point of singularity.

  • Patent number: 8173006
    Abstract: An electrolyzed water production apparatus and method safely and simply produce electrolyzed water having a sterilizing action, having a physiologically neutral pH value, and, in addition, simultaneously with strong acidic electrolyzed water and strong alkaline electrolyzed water depending upon the structure. The electrolyzed water production apparatus has an electrolyzer tank with an end that receives or stores raw water, and a power supply. The interior portion of the electrolyzer tank is partitioned by a plurality of diaphragms into a plurality of regions. An anode and a cathode (constituting an electrode pair) are positioned on either side of the diaphragm. In a certain region of the electrolyzer tank, an anode and a cathode are arranged so as to face each other without a diaphragm sandwiched between them. When raw water for electrolysis is electrolyzed, electrolyzed water having a desired pH of a neutral range is produced during electrolysis.

    Abstract: A method for membrane permeabilization of biological cells contained in a product is disclosed. According to one aspect, the method is applied in a treatment device including at least one treatment chamber emitting a pulsed electric field. According to another aspect, the method includes supplying the treatment device with a product including biological cells at a predetermined supply flow rate from a supply unit, introducing the product including the biological cells into the treatment chamber at an introduction flow rate, treating the product introduced into the chamber with a pulsed electric field, and reintroducing the treated product, at a predetermined feedback flow rate at a point that is downstream from the supply unit. According to some aspects, the introduction flow rate includes the feedback flow rate and the supply flow rate.

  • Patent number: 8025787
    Abstract: A method and apparatus are provided for receiving a cleaning liquid having a pH in a range between pH6-pH8 and an oxidation reduction potential (ORP) between ±50 mV. The liquid is converted into an anolyte liquid and a catholyte liquid having respective pHs outside of the range between pH6-pH8 and having respective ORPs outside the range between ±50 mV. The anolyte and catholyte liquids are applied to a surface, wherein the anolyte and catholyte liquids are, for example, in a combined state on the surface and substantially neutralize to a pH between pH6-pH8 and an ORP between ±50 mV within one minute of the time at which the anolyte and catholyte liquids are converted.

  • Patent number: 8017087
    Abstract: An oxygenation device consists of a first vertically oriented tube having electrically conductive plates for forming oxygen by electrolysis. Above the plates is a pump formed by a second length of tube fitted within the first tube with a spacing between the walls of the first and second lengths of tubing thereby forming a cavity. Compressed air is admitted into the cavity. The second length of tubing has an open lower end for receiving air from the cavity. Air enters the second tube in belches that form large bubbles.

  • Publication number: 20110095225
    Abstract: Methods, systems, and apparatuses for extracting non-polar lipids from microalgae are achieved using a lipid extraction device having an anode and a cathode that forms a channel and defines a fluid flow path through which an aqueous slurry is passed. An electromotive force is applied across the channel at a gap distance in a range from 0.5 mm to 200 mm to cause the non-polar lipids to be released from the algae cells. The non-polar lipids can be extracted at a high throughput rate and with low concentrations of polar lipids such as phospholipids and chlorophyll.

  • Patent number: 7897030
    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.
