Provided herein is a composition for use as a hardening regulator, e.g. hardening accelerator or hardening retarder, for building materials, as well as methods for producing thereof. The composition is characterized by a biphasic nature in which solid calcium silicate nanoparticles are dispersed in an aqueous solution comprising inorganic water soluble iron, and possibly zinc, silicate and calcium, species. Additional components such as inorganic ions and silica nanoparticles can be present. Depending on the relative ratio of each component, the composition can be used either for retarding or for accelerating the hardening process of a building material such as cement or concretes. The so-obtained building material further shows an enhanced strength upon compressive forces applied thereon.

Hardening acceleration/hardening retardation composition for building materials

Nanoparticles and method for producing uniform silicate-based nanoparticles are disclosed. The method comprises a step of injecting into tubular branched elements comprising static mixers a first aqueous solution comprising a water-soluble silicate compound and a second aqueous solution comprising a water-soluble compound releasing cationic species in solution, and allowing the reaction between the first and the second aqueous solutions in a micro-mixing regime, the method being characterized in that the overall mixing time is kept below 10s. A further step of allowing the solution obtained in the micro-mixing regime to mix in a macromixing regime. Nanoparticles obtained through the present method are also disclosed.

Nanoparticles and method for producing uniform silicate-based nanoparticles

The invention relates to an improved process for the production of powders of an inhalable medicament by crystallization from a supersaturated fluid containing said medicament, the method comprising passing along a tubular reactor

Process for the manufacture of powders of inhalable medicaments

A process for the production of powders by precipitation from a liquid reaction mixture comprises passing along a tubular reactor a segmented reaction flow comprised of discrete volumes of the reaction mixture separated by discrete volumes of a separating fluid which is substantially immiscible with said reaction mixture, the residence time of said discrete volumes of reaction mixture in the reactor being sufficient for the precipitation reaction to be effected.

Production of powders

The ceramic/metal composite material is comprised of a ceramic phase with particles of alumina or of a solid solution based on alumina and a refractory phase including titanium nitride and/or carbonitride and a metallic matrix based on Ni, Co, Fe. The interface between the particles of alumina or the solid solution of alumina and the metallic matrix is rich in nitrogen and in titanium or in compounds thereof.
