Abstract: There is provided a method of manufacturing nanoparticles comprising the steps of feeding a core precursor into a plasma torch in a plasma reactor, thereby producing a vapor of silicon or alloy thereof; and allowing the vapor to migrate to a quenching zone of the plasma reactor, thereby cooling the vapor and allowing condensation of the vapor into a nanoparticle core made of the silicon or alloy thereof, wherein the quenching gas comprises a passivating gas precursor that reacts with the surface of the core in the quenching zone produce a passivation layer covering the core, thereby producing said nanoparticles. The present invention also relates to nanoparticles comprising a core covered with a passivation layer, the core being made of silicon or an alloy thereof, as well as their use, in particular in the manufacture of anodes.

Abstract: The present invention discloses a method for chemically marking metal products such as metal ingots and other rough or processed metal materials. More specifically, the aim of the present invention is the use of tracers during the method for casting or other methods for manufacturing metal products. These tracers in turn can be identified by physico-chemical methods for confirming the specification of the product, the source of the products or of other similar elements and to assist anti-counterfeiting measures or the identification of production batches or cycles.
