A photovoltaic system including a solar cell having a hysteretic behavior; and a power device configured to extract a maximum power from the solar cell by forcing power oscillations of the power output by the solar cell.

Device and method for performing maximum power point tracking for photovoltaic devices in presence of hysteresis

Endosseous implant to be applied to a human or animal bone, wherein the surface of the implant is made from titanium or a titanium alloy, said implant having a smooth or rough surface texture, which is characterized in that said surface has been treated with at least one selected organic phosphonate compound or a pharmaceutically acceptable salt or ester or an amide thereof; process for producing said implants.

Endosseous implant

Endosseous implant to be applied to human or animal bone, said implant having a surface made from a selected metal or a selected metal alloy or a ceramic, whereby said metal resp. metal alloy is selected from chromium, niobium, tantalum, vanadium, zirconium, aluminium, cobalt, nickel, stainless steels or an alloy thereof, said surface having a smooth or rough texture, characterized in that said surface has been treated with at least one pharmaceutically acceptable organic compound carrying at least one phosphonic acid group or a derivative thereof preferably a pharmaceutically acceptable salt or ester or amid thereof and method for producing said implant.
