Abstract: 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.

Abstract: 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.

Abstract: Conductive diamond micro-electrode sensors and sensor arrays are disclosed for in vivo chemical sensing. Also provided is a method of fabrication of individual sensors and sensor arrays. Reliable, sensitive and selective chemical micro-sensors may be constructed for real-time, continuous monitoring of neurotransmitters and neuro-active substances in vivo. Each sensor comprises a conductive microwire, having a distal end comprising a tip, coated with nanocrystalline or ultrananocrystalline conductive diamond, and an overlying insulating layer. Active sensor areas of the conductive diamond layer are defined by openings in the insulating layer at the distal end. Multiple sensor areas may be defined by a 2 or 3 dimensional pattern of openings near the tip. This structure limits interference from surrounding areas for improved signal to noise ratio, sensitivity and selectivity. Using fast-scan cyclic voltammetry and high speed multiplexers, multiple sensors can be arrayed to provide 3-D spatial, and near real-time monitoring.

Abstract: A method of fabrication, a device structure and a submount comprising high thermal conductivity (HTC) diamond on a HTC metal substrate, for thermal dissipation, are disclosed. The surface roughness of the diamond layer is controlled by depositing diamond on a sacrificial substrate, such as a polished silicon wafer, having a specific surface roughness. Following deposition of the diamond layer, an adhesion layer, e.g. comprising a refractory metal, such as tantalum, and at least one layer of HTC metal is provided. The HTC metal substrate is preferably copper or silver, and may be provided by electroforming metal onto a thin sputtered base layer, and optionally bonding another metal layer. The electrically non-conductive diamond layer has a smooth exposed surface, preferably ≦10 nm RMS, suitable for patterning of contact metallization and/or bonding to a semiconductor device. Methods are also disclosed for patterning the diamond on metal substrate to facilitate dicing.
