The object of the present invention relates to a nanoparticulate aerosol generator comprising a compressed gas reservoir () connected to a nanoparticulate material receptacle () through an operational valve (′), wherein said receptacle () comprises an outlet hole () for the aerosol. Advantageously, the outlet of said nanoparticulate material receptacle () is connected to or inserted into a pressurized aerosol distribution chamber () equipped with a hole () for the exit of said aerosol out of the chamber (). The invention provides the possibility of using different types of nanoparticles with sizes less than 100 nanometers continuously over time during long production periods of more than three hours. The invention also relates to a method for continuously generating nanoparticulate aerosols associated with the mentioned generator.

An identification and verification system and a process for said identification and verification of documents is disclosed, which is based on the use of nanoparticles embedded or adsorbed in the document support, utilizing the different optical reflectance characteristics thereof in order to obtain, by combining several nanoparticles with specific characteristics, a high effectiveness in the identification of counterfeits.

Object authentication method and use therof

A process for the additivation of synthetic fibers, artificial fibers and polymers conferring special properties to them, the process comprising the following steps: the encapsulation of an additive in the pores of a porous material; the incorporation of particles of the porous material (capsules) into the polymer matrix of the fiber; and spinning of the fiber; the capsule withstanding the temperatures and other conditions of the different manufacturing processes which the fibers might undergo and the introduction of the additive into the polymer matrix thereof, characterised in that the porous material is a metal oxide, a zeolite, an aluminophosphate, clay, a carbon material, a hybrid organic-inorganic material or a porous polymer. The invention is an improvement in the additivation process of fibers and polymers in terms of the nature of the capsules used, the increase in the storage capacity of additives thereof, the process of incorporating the capsules into the polymer matrix of the fibers and the fact that the present invention refers to an industrial process.
