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

This invention concerns a novel method for surface derivatization of electrode materials for Li-ion batteries. The derivatization is based on adsorption of a composite assembly consisting of amphiphilic redox active molecule attached to single walled carbon nanotube (SWCNT). Its role consists in the enhancement of electronic conductivity of electrode materials, such as phosphate olivines, without requesting any significant increase of the electrode volume and mass. The SWCNT is linked to the redox molecule via non-covalent or covalent interaction with the hydrophobic part of the molecule or electrostatic interaction. The hydrophilic part of the molecule serves as the anchoring site for surface modification of the electrode active material. The redox potential of the molecule is close to the redox potential of the electrode active material. The adsorbed assembly of redox-molecule & SWCNT thus improves the charge transfer from a current collector to the electrode active material.

A dimeric composition of the formula: ##STR1## wherein L', L', L'', and L'' are each a bidentate ligand having at least one functional substituent, the ligand selected from bipyridine, phenanthroline, 2-phenylpyridine, bipyrimidine, and bipyrazyl and the functional substituent selected from carboxylic acid, ester, amide, halogenide, anhydride, acyl ketone, alkyl ketone, acid chloride, sulfonic acid, phosphonic acid, and nitro and nitroso groups. An electrochemical oxidation process for the production of the above functionally substituted bidentate ligand diaqua oxo-bridged ruthenium dimers and their use as water oxidation catalysts is described.

A catalyst having a mixture of Ru and RuO.sub.x, wherein x is greater than 0 and equal to or less than 2, supported by a suitable metal oxide support material is suitable for the heterogeneous catalytic gas phase direct methane production from hydrogen and carbon dioxide at mild temperatures as low as 25.degree. C. and atmospheric pressure. Photo-methanation using such catalysts having photoexcitable support materials significantly increases the rate of methane production and the methane yield, yielding almost stoichiometrically quantitative amounts of methane according to the Sabatier reaction.
