The method of making an implant consists on coating of a supporting structure () with synthetic hydroxyapatite by immersing the supporting structure () in a suspension () and triggering of a cavitation in a portion of the suspension () being in contact with the supporting structure (). The suspension () is formed by a liquid external phase, advantageously water, and internal phase, i.e. particles of synthetic hydroxyapatite having an average particle size not exceeding 100 nm and containing structural water in an amount from 2 to 6% by weight. The implant is coated with the above described hydroxyapatite subjected to cavitation and a thickness of 50 nm to 1000 nm, advantageously 50 nm to 300 nm.

A method of measuring oxygen partial pressure in gases, such as hot engine exhaust gases, uses a calibrated luminescence sensor and comprises the steps of bringing nanocrystalline zirconium dioxide ZrO2 () in said sensor into contact with a gas to be measured, illuminating the zirconium dioxide with a UV-VIS light pulse emitted from a light source () and adapted to induce luminescence of the zirconium dioxide, registering the time dependence of the luminescence intensity of the ZrO2 using a photodetector () and a recorder (), determining a particular intensity, e.g., the maximum intensity of the registered luminescence pulse, and comparing said determined intensity with calibration data of the luminescence intensity as a function of oxygen partial pressure for the sensor temperature at the time of the measurement.
