Abstract: The invention relates to a method whereby it is possible to obtain nanowires by means of applying a laser radiation and simultaneously injecting a supersonic gas stream on the precursor material in atmospheric conditions and at room temperature. This method involves a considerable improvement compared to conventional methods because it can be carried out on commercial samples without any prior preparation, a very precise control of the process and environmental conditions not being necessary, which significantly decreases the process time and the economic cost thereof. The method object of the present invention also allows synthesizing nanowires in very reduced processing times.

Abstract: The osteointegration of osseous fixing implants may be improved through a series of surface treatments. These treatments comprise a cleaning and passivation process, the application of a coating of CaUPVHXOYCZ to the implant, where subindexes u, v, x, y, and z are natural numbers including zero with variable stoichiometry, and a sterilization process by irradiation. The flexibility of this method provides for the control of physical and chemical properties of the obtained surface in order to match the properties with those of the bone in which the implant will be placed.
