Disclosed embodiments include methods for cleaning wax, substantially equivalent impurities, and other contaminants from porous stones in historical monuments and artworks using nondestructive means. According to one embodiment the method for removal of contaminants from porous stones using laser comprises the following method steps: (a) identifying regions of a contaminant on the porous stone monument; (b) characterizing the contaminant on the porous stone monument; (c) exposing the contaminant on the porous stone monument to irradiation from a laser characterized by a wavelength, a pulse length, a repetition rate, and a laser energy fluence determined and optimized for a given contaminant-porous stone system and the laser characteristics; and (d) adaptively evaluating the cleaning results by quantifying the thickness of the remaining contaminant.

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 Ca P H O C 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.
