Abstract: The invention relates to a method for producing particles with pore structures, by means of a hybrid process of atomization via drying-cooling, from a water-in-oil-type emulsion of a composition of a non-solubilized and in melt state matrix. The production method comprises: i) forming a water-in-oil-type emulsion consisting of a composition of a solvent that is aqueous or soluble in water (dispersed phase) and a composition of a non-solubilized and in melt state matrix (continuous phase); ii) forming discrete particles from the emulsion via atomization, using a flow of gas at high pressure and temperature; iii) immediately removing the solvent via evaporation; and iv) subsequently cooling the formed discrete particles, resulting in porous particles that are substantially free from solvents.

Abstract: The present invention relates to fertilizer particles encapsulated in modified chitosan and a method of obtaining them. The particles described in this invention allow a controlled, moderate, or gradual release of an active material from a reserve substrate to another medium, in order to increase the effectiveness of the active material by prolonging its action over time. This invention is characterized in that the active components of said formulations are capable of causing a synergistic effect, considerably increasing the growth and development of plants.

Abstract: The invention relates to a continuous mixing/extrusion method, assisted by ultrasound waves with a variable amplitude and frequency, for the preparation of nanocompounds based on polymers, preferably thermoplastics and nanoparticles, at a concentration of up to 60 wt.-% of the total weight of the polymer/nanoparticle mixture. According to the invention, the polymer/nanoparticle mixture is subjected in the molten state to a discrete and continuous sweep with a variable amplitude and frequency, of between 15 kHz and 50 kHz.
