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： 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.
