    摘要： The present invention relates to an apparatus for the production of ozone from water comprising at least one cell, consisting of an anode, a cathode and an interposed cation-conducting membrane, wherein the membrane conductively connects the anode and the cathode while forming flow channels for water that are separated from one another as anode and cathode chambers and wherein the flow channels are configured to allow for the recirculation of the water flow within the chambers. The present invention further relates to an electrochemical method and apparatus for producing ozone or dissolved ozone in water in high concentrations by mean of recirculation of water between at least one chamber and at least one water tank.

    摘要： The invention describes a method of ozone titration sensing which utilizes an ozone addition to a target solution, detection of ozone using an Oxidation-Reduction Potential (ORP) electrode or an Ultraviolet (UV) absorption photodiode or other means to detect ozone and the determination of the relative concentration of organics or pathogens subject to ozone oxidation which are present in the target solution. The inventive sensing method can be usefully employed to determine the relative concentration of pathogens such as viruses, bacteria and/or parasites that are readily oxidizable by ozone in aqueous solutions. The inventive sensing method may be used to control an ozone (or other oxidizing or disinfecting) compound dispensing system to optimize the dosage of ozone (or other disinfecting compound) necessary to produce a desired kill ratio or to generate a desired residual of ozone concentration in an aqueous solution after pathogen disinfection.

    摘要： A durable composite diamond electrode is disclosed which comprise at least a relatively thicker conductive UNCD (Ultrananocrystalline Diamond) layer, with low deposition cost, on a substrate underlying a relatively thinner conductive MCD (Microcrystalline Diamond) layer. The electrode exhibits long life and superior delamination resistance under extremely stressed electrochemical oxidation conditions. It is hypothesized that this improvement in electrode reliability is due to a combination of stress relief by the composite film with the slightly “softer” underlying UNCD “root” layer and the electrochemically durable overlying MCD “shield” layer, an effective disruption mechanism of the fracture propagation between the compositing layers, and thermal expansion coefficient match between the diamond layers and the substrate. The diamond composite electrode can be applied to any electrochemical application requiring extreme voltages/current densities, extreme reliability or biomedical inertness such as electrochemical systems to generate ozone, hydroxyl radicals, or biomedical electrode applications.

    摘要： A novel composite diamond film comprising of a relatively thick layer of UNCD (Ultrananocrystalline Diamond) with a Young's modulus of less than 900 GPa and a relatively thin MCD (microcrystalline diamond) outermost layer with a Young's modulus of greater than 900 GPa, has been shown to exhibit superior delamination resistance under extreme shear stress. It is hypothesized that this improvement is due to a combination of stress relief by the composite film with a slightly “softer” UNCD layer, a disruption of the fracture mechanism through the composite layer(s), and the near ideal chemical and thermal expansion coefficient match between the two diamond layers. The combination of a thick but “softer” underlying UNCD layer with a thin but harder overlying MCD layer provides an excellent compromise between the low deposition cost and smoothness of UNCD with the extreme hardness and unparalleled chemical, electrochemical and immunological inertness of even a thin layer of MCD. The MCD layer's roughness is minimized and its adhesion maximized by the use of a thin layer of MCD and its deposition on the smooth surface of the chemically nearly identical underlying UNCD layer. The composite film can be applied to any application currently utilizing a diamond or a similar hard film, including cutting tools, abrasive surfaces, electrochemistry, biomedical applications such as human implants or thermally conductive films and the like, requiring superior durability, chemical resistance and/or immunological inertness.

    摘要： A novel durable composite diamond electrode comprising at least a relatively thicker conductive layer of UNCD (Ultrananocrystalline Diamond) layer with a Young's modulus of less than 900 GPa on a niobium substrate underlying a relatively thinner conductive MCD (Microcrystalline Diamond) layer with a Young's modulus of greater than 900 GPa, has been shown to exhibit superior delamination resistance under extreme shear stress during electrochemical oxidation reliability testing. Highly accelerated lifetime testing of these durable composite diamond electrodes at a constant current density of 2.5 amps/cm2 (25000 amps/m2) in a 1 M NaCl (58 g/L) solution, have demonstrated lifetimes before delamination failure of greater than 2000 hours (i.e. >5000 Ahr/cm2). Using a conservative estimate of lifetime to failure with a cubed dependence on current density, the lifetime at a more typical operating current density of 0.25 amps/cm2 (2500 amps/m2) would be at least 2,000,000 hours (228 years) and >3.5 years at 1.0 amps/cm2 (a more typical current density for ozone generation). It is hypothesized that this improvement in durable diamond electrode reliability is due to a combination of stress relief by the composite film with a slightly “softer” underlying UNCD layer, a disruption of the fracture propagation mechanism between the two layer(s), and the near ideal chemical and thermal expansion coefficient match between the two diamond layers and the hardness and durability of the overlying MCD layer as deposited on an electrode substrate. The combination of a thick but “softer” underlying UNCD layer with a thin but harder overlying MCD layer provides an excellent compromise between the low deposition cost and conductivity of UNCD with the extreme hardness, large grain size and unparalleled chemical and biochemical inertness of even a thin layer of MCD. The inventive two layer diamond composite electrode can be applied to any electrochemical application requiring extreme voltages/current densities, extreme reliability, hardness or biomedical inertness such as electrochemical systems to generate ozone, hydroxyl radicals, deep sea chlorine generators or biomedical electrode applications such as pacemakers, biosensors, cardiovascular devices or automatic defibrillators.
