摘要:
A CVD single crystal diamond material suitable for use in, or as, an optical device or element. It is suitable for use in a wide range of optical applications such as, for example, optical windows, laser windows, optical reflectors, optical refractors and gratings, and etalons. The CVD diamond material is produced by a CVD method in the presence of a controlled low level of nitrogen to control the development of crystal defects and thus achieve a diamond material having key characteristics for optical applications.

摘要:
A body of single crystal CVD (chemical vapour deposition) diamond particularly suitable as a wear resistant material for wear applications, such as wire drawing dies, graphical tools or stichels, or fluid jet nozzles. The diamond typically has a low wear rate, exhibits a low birefringence indicative of low strain and possesses an ability to be processed to show a high surface polish.
摘要:
A fast heating cathode comprises a layer of diamond, a thermionic emitting element in thermal contact with a surface of the diamond layer and means to heat the diamond layer.
摘要:
A method and system is disclosed for monitoring one or more characteristics associated with a fluid. An insulating layer comprising non-conducting diamond is positioned within a housing and has a surface exposed directly or indirectly to the fluid. A plurality of microelectrodes made of electrically conducting diamond each have a surface exposed directly or indirectly to the fluid. An electrical circuit in electrical communication with each of the microelectrodes is adapted to convert electrical signals from the microelectrodes into at least one signal associated with a characteristic being monitored. The sensing system is well suited to hydrocarbon wellbore related applications, but can also be used in other applications.

摘要:
A method of decomposing an organic liquid, having a solubility in water of 0 or less than 50 g/l at 25° C., comprising: a) emulsifying an amount of the organic liquid in an amount of an aqueous medium to form an emulsion of the organic liquid in the aqueous medium; and b) electrochemically decomposing the emulsified organic liquid on a surface of an oscillating electrode in an electrochemical cell, wherein the electrode is oscillating at a frequency of at least 5 KHz.
