This invention is directed to nanocomposite comprising biodegradable polymers and inorganic nanoparticles or nanotubes, methods of preparation and uses thereof.

Nanocomposites comprising biodegradable polymers and inorganic nanoparticles, methods of preparation and uses thereof

This invention is directed to composites and films comprising hydroxyapatite, biodegradable polymer, a biocompatible surfactant with inorganic fullerene-like (IF) nanoparticles or inorganic nanotubes (INT); methods of preparation and uses thereof.

Hydroxyapatite based composites and films thereof

This invention provides electromechanical resonators based on metal chalcogenide nanotubes. The invention further provides methods of fabrication of electromechanical resonators and methods of use of such electromechanical resonators.

Electromechanical resonators based on metal-chalcogenide nanotubes

A new approach is presented to reduce encrustation of catheters by the application of nanoparticles. It is demonstrated that the negatively surface charged nanoparticles produce coating films comprised of long-range domains in which the nanoparticles are self-assembled into a mosaic-like order, showing a relatively small tendency to agglomerate.

Attenuation of encrustation of medical devices using coatings of inorganic fullerene-like nanoparticles

The present invention provides an article, at least part of it being coated by inorganic fullerene-like (IF) nanoparticles or composite containing such nanoparticles. Preferably, the invention provides an article made of metal, for use in dentistry or medicine e.g. archwire, needle or catheter, having a friction-reducing film, and methods for coating such articles with a friction-reducing film.

Low friction coatings for use in dental and medical devices

The present invention concerns inorganic nanostructures comprising soft metals at low concentrations and catalytic processes utilizing soft metals for obtaining inorganic nanostructures.

Catalytic processes for obtaining inorganic nanostructures by using soft metals

A lubricating and shock absorbing materials are described, which are based on nanoparticles having the formula A-B-chalcogenide. Processes for their manufacture are also described.

Nanostructures, their use and process for their production

This invention relates to a hybrid component comprising at least one nanoparticle of inorganic layered compound (in the form of fullerene-like structure or nanotube), and at least one metal nanoparticle, uses thereof as a catalyst, (e.g. photocatalysis) and processes for its preparation.

Metal nanoparticle deposited inorganic nanostructure hybrids, uses thereof and processes for their preparation

The present invention provides a selective coating of an endodontic file, in which the distal end of the file is uncoated or alternatively leaving the outermost part of the blades of the distal end portion uncoated. The distribution of the nanoparticles is thus non uniform along the surface of the file leaving only a part of the file coated. In the present invention, the distal end of the device being subjected to the highest torque is either uncoated at all, or has a coated core and uncoated blades.

Endodontic files and method of preparation thereof

A nanostructure, being either an Inorganic Fullerene-like (IF) nanostructure or an Inorganic Nanotube (INT), having the formula A-B-chalcogenide are described. A being a metal or transition metal or an alloy of metals and/or transition metals, B being a metal or transition metal B different from that of A and x being &#x2266;0.3. A process for their manufacture and their use for modifying the electronic character of A-chalcogenide are described.

Fullerene-like nanostructures, their use and process for their production

The present invention provides a process for obtaining fullerene-like metal chalcogenide nanoparticles, comprising feeding a metal precursor selected from metal halide, metal carbonyl, organo-metallic compound and metal oxyhalide vapor into a reaction chamber towards a reaction zone to interact with a flow of at least one chalcogen material in gas phase, the temperature conditions in said reaction zone being such to enable the formation of the fullerene-like metal chalcogenide nanoparticles product. The present invention further provides novel IF metal chalcogenides nanoparticles with spherical shape and optionally having a very small or no hollow core exhibiting excellent tribological behaviour. The present invention further provides an apparatus for preparing various IF nanostructures.

Process and apparatus for producing inorganic fullerene-like nanoparticles

A process and apparatus are presented for obtaining inorganic fullerene-like nanostructures. A metal oxide is evaporated at predetermined temperature conditions, and is swept towards a reacting zone, to which first and second gas phase reacting agents are concurrently swept. The evaporated metal oxide thus interacts with the first reacting agent and is converted into metal suboxide nanoparticles in the gas phase. The condensing metal suboxide nanoparticles interact with the second reacting agent in the gas phase resulting in substantially pure phase of the inorganic fullerene-like nanoparticles.
