    摘要: A diamond element (10) having a convex surface is disclosed, the convex surface including a spherical segment for which the maximum peak to valley deviation from a perfect spherical surface is less than about 5 μm. The diamond element (10) may be a solid polycrystalline diamond material and/or may comprise base material which is coated with diamond. Alternatively or in addition, the RMS deviation from a perfect spherical surface may be less than about 500 nm, or the RMS roughness less than about 30 nm. A diamond element (10) with a radius of curvature less than about 20 mm is also disclosed. In one aspect a diamond element (10) having a conical half-angle greater than about 10° is described. Diamond elements (10) of this type are intended for use as metrology tips. Key to this invention is the realization that a diamond surface, particularly a diamond surface with low Ra (roughness) and which is free of defects such as pits, digs and scratches, accumulates less material from the surface being measured, and thus provides a longer life.

    摘要: An electrochemical sensor comprising: a reference electrode (4) formed of an electrically conductive synthetic doped diamond material and configured to be located in electrical contact with a solution (8) to be analysed; a sensing electrode (2) formed of an electrically conductive synthetic doped diamond material and configured to be located in contact with the solution (8) to be analysed; an electrical controller (10) configured to conduct stripping voltammetric measurements by applying a voltage to the sensing electrode (2), to change the applied voltage relative to the reference electrode (4), and to measure an electric current flowing through the sensing electrode (2) thereby generating voltammetry data; and a calibration system configured to provide an in-situ calibration for providing a reference point in the voltammetric data since the potential of the diamond reference electrode is non fixed and floating. Consequently, assigning of peaks (M1, M2, M3) in the voltammetry data to chemical species (M1, M2, M3) is possible, thereby allowing the type and concentration of chemical species in the solution (8) to be determined. The in-situ calibration consists of: 1-using a spectrometer for X-rays, Gamma rays or fluorescence measurements integrated in the sensor, 2-using a known redox couple added to the solution that will provide a reference peak in the voltammetric data, or 3-producing in-situ ionic species at the vicinity of the reference electrode.

    摘要: A synthetic single crystal diamond material comprising: a first region comprising electron donor defects; a second region comprising quantum spin defects; and a third region between the first and second regions. The second and third regions have a lower concentration of electron donor defects than the first region. The first and second regions are sufficiently close to allow electrons to be donated from the first region to the second region, thus forming negatively charged quantum spin defects in the second and positively charged defects in the first region, and sufficiently far apart to reduce other coupling interactions between the first and second regions which would otherwise unduly reduce the decoherence time of the plurality of quantum spin defects and/or produce strain broaden of a spectral line width of the plurality of quantum spin defects in the second region.
