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.

Optical quality diamond material

A control system for a vehicle having an electric motor for providing drive torque to at least one wheel of the vehicle, an internal combustion engine for providing drive torque to at least one wheel of the vehicle, a manual transmission unit having a user selectable gear ratio that includes at least one user selectable forward gear and/or reverse gear, and a clutch actuator, the control system comprising a controller arranged to have three user selectable modes of operation, wherein in a first mode of operation the controller is arranged to allow the clutch actuator to engage and disengage the internal combustion engine from the manual transmission unit based upon a user selection, wherein when the clutch actuator is arranged to engage the internal combustion engine with the manual transmission unit, torque generated by the internal combustion engine is applied to the at least one wheel, and the electric motor is arranged to provide drive torque to the at least one wheel of the vehicle based on whether the user has selected the at least one forward gear or the at least one reverse gear; and in a second mode of operation the controller is arranged to allow the clutch actuator to engage and disengage the internal combustion engine from the manual transmission unit based upon a user selection, and to prevent the electric motor from providing drive torque to the at least one wheel of the vehicle; and in a third mode of operation the controller is arranged to allow the electric motor to provide drive torque to the at least one wheel of the vehicle based on whether the user has selected the at least one forward gear or the at least one reverse gear and to configure the clutch actuator to disengage the internal combustion engine from the manual transmission unit.

Control system for a vehicle

A single crystal diamond prepared by CVD and having one or more electronic characteristics; making the diamond suitable for electronic applications. Also provided is a method of making the single crystal CVD diamond.

Single crystal diamond prepared by CVD

Microelectrode comprising a body formed from electrically non-conducting material and including at least one region of electrically conducting material and at least one passage extending through the body of non-conducting material and the region of conducting material, the electrically conducting region presenting an area of electrically conducting material to a fluid flowing through the passage in use. An electrochemical cell which includes such a microelectrode is also disclosed.

Microelectrode array

An electrode comprising an electrically conducting diamond plate wherein the diamond plate comprises at least one elongate aperture and having an aperture edge length per unit working area of the diamond plate of greater than about 4 mm/mm, electrolysis cells comprising such electrodes, methods of treating water using such electrolysis cells and a method of production of ozone are disclosed.

Diamond electrode

A radiation detector comprises a substrate of diamond material and at least one electrode formed at a surface of the substrate. The electrode comprises electrically conductive material deposited in a cavity in the surface of the substrate so that at least a portion of the material of the electrode is below the surface of the substrate. The cavity will typically be an elongate trench or channel in which electrically conductive material such as boron-doped diamond is deposited. In some embodiments, at least two electrodes are located adjacent to one another at the surface of the substrate. In other embodiments, the device has a plurality of electrodes, at least one of which is located at a first surface and at least one of which is located at an opposed second surface of the substrate. In the latter case, an electrode at one surface of the substrate can be connected to an electrode at the opposed surface of the substrate by means of a conductive via, which consists of a through-hole filled or coated with conductive material. Typically, the electrodes are arranged in an interdigitated configuration, each electrode having a plurality of elongate electrode elements. Each such electrode element extends parallel to at least one adjacent electrode element of another electrode.
