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

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

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.

Method and apparatus for producing inorganic fullerene-like nanoparticles

The present invention is related to an apparatus for the production of inorganic fullerene-like (IF) nanoparticles and nanotubes. The apparatus comprises a chemical reactor, and is further associated with a feeding set up and with a temperature control means for controlling the temperature along the reaction path inside the reactor so as to maintain the temperature to be substantially constant. The invention is further directed to a method for the synthesis of IF-WO3 nanoparticles having spherical shape and having a size up to 0.5 mu m and nanotubes having a length of up to several hundred mu m and a cross-sectional dimension of up to 200 nanometer.
