    Abstract: An electrode comprising synthetic high-pressure high-temperature diamond material, the diamond material comprising a substitutional boron concentration of between 1×1020 and 5×1021 atoms/cm3 and a nitrogen concentration of no more than 1019 atoms/cm3. The electrode has a ΔE3/4-1/4 as measured with respect to a saturated calomel reference electrode in an aqueous solution containing 0.1 M KNO3 and 1 mM of Ru(NH3)63+ selected any of less than 70 mV, less than 68 mV, less than 66 mV, and less than 64 mV, and/or a peak to peak separation ΔEp as measured with respect to a saturated calomel reference electrode in an aqueous solution containing 0.1 M KNO3 and 1 mM of Ru(NH3)63+ selected any of less than 70 mV, less than 68 mV, less than 66 mV, and less than 64 mV.

    Abstract: A defect centre-based sensor is disclosed. The sensor comprises instrumentation which includes a generator for causing excitation in an active element, for example a diamond, and a detector for measuring a transition in the active element. The generator is an optical source and/or the detector is an optical detector. The sensor further comprises an optical waveguide and a sensor head in communication with the source and/or the detector via the optical waveguide. The sensor head houses the active element having at least one defect centre, for example, a nitrogen vacancy, responsive to an applied magnetic field, electric field or temperature and a signal delivery arrangement, for example at least one lens, arranged to optically couple the optical waveguide to the active element.

    Abstract: A method is provided of forming a coating within an internal pathway. The method comprises: providing a body having an inlet and an outlet and an internal surface which defines an internal pathway extending within the body between the inlet and the outlet; streaming a mixture of a gas and a fluid along at least a part of a length of the internal pathway, the fluid comprising one or more substances for forming a solid coating on the internal surface, the fluid being a liquid solution of said one or more substances in a solvent or being a dispersion with at least one of said one or more substances being solid particles dispersed in a liquid continuous phase; during said streaming of the mixture, applying localised heat progressively along said at least a part of the length of the internal pathway. The progressive application of localised heat causes, within said at least a part of the length of the internal pathway, formation from the one or more substances of a solid coating on the internal surface.
