摘要： An electrochemical system and method are disclosed for On Site Generation (OSG) of oxidants, such as free available chlorine, mixed oxidants and persulfate. Operation at high current density, using at least a diamond anode, provides for higher current efficiency, extended lifetime operation, and improved cost efficiency. High current density operation, in either a single pass or recycle mode, provides for rapid generation of oxidants, with high current efficiency, which potentially allows for more compact systems. Beneficially, operation in reverse polarity for a short cleaning cycle manages scaling, provides for improved efficiency and electrode lifetime and allows for use of impure feedstocks without requiring water softeners. Systems have application for generation of chlorine or other oxidants, including mixed oxidants providing high disinfection rate per unit of oxidant, e.g. for water treatment to remove microorganisms or for degradation of organics in industrial waste water.

摘要： An electrolytic ozone generator includes an anode with a longitudinal edge, a cathode with a longitudinal edge spaced apart from the cathode, and an isolator. The isolator electrically separates the cathode from the anode and is semi-impermeable. The anode and cathode are impermeable for generating ozone in a flow area fluidly coupling longitudinal edges of the anode and the cathode. Ozone water apparatus, methods of making electrolytic ozone generators, and methods of generating ozone using electrolytic ozone generators are also described.

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 an underlying relatively thin 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. 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.
摘要翻译：已经示出了由杨氏模量小于900GPa的相对较厚的UNCD层（Ultrananocrystalline Diamond）和具有大于900GPa的杨氏模量的相对薄的MCD（微晶金刚石）层组成的新型复合金刚石薄膜。在极端剪切应力下表现出优异的耐分层性。假设这种改进是由于复合膜与轻微“较软”的UNCD层的应力释放的组合，通过复合层的断裂机理的破坏以及接近理想的化学和热膨胀系数两颗钻石层之间的匹配。厚厚但“较软”的底层UNCD层与薄但较硬的覆盖MCD层的组合在UNCD的低沉积成本和平滑度之间提供了极好的折中，具有极高的硬度和无与伦比的化学，电化学和免疫惰性甚至薄层的MCD。 MCD层的粗糙度被最小化，并且其粘附通过使用MCD的薄层及其沉积在化学上几乎相同的底层UNCD层的光滑表面上而最大化。复合膜可以应用于目前使用金刚石或类似硬膜的任何应用，包括切割工具，磨料表面，电化学，生物医学应用如人造植物或导热膜等，需要优异的耐久性，耐化学性和/ 或免疫惰性。

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.

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.

摘要： A method for forming diamond nanostructures with large specific area can include forming porous diamond nanostructures by means of selectively etching sp2-bonded carbon and partially removing sp3-bonded carbon in nanocrystalline diamond (NCD) and ultrananocrystalline diamond (UNCD® diamond). The diamond nanostructures achieved from the disclosed method can include a long shaft surrounded by a school of barbs. The nanostructure can provide a significantly larger surface area than diamond without such a nanostructure and its fabrication provides relative ease of manufacture compared to traditional techniques.
