Abstract: This disclosure provides a process for preparing transparent emulsions, in particular emulsions that are free of solvents such as propylene glycol, for use in producing clear beverages.

Abstract: A method for preparation of liquid, semi-liquid or solid particles through formation of an initial emulsion and consecutive deformation and/or breakage of the particles by means of temperature change. The formed particles may further be polymerized, physically or chemically modified and/or functionalized. The shape and size of the particles depend on the oil used, the size of the emulsion droplets in the initial emulsion, the surfactant used and the cooling/heating rate or temperature, and finally the nature of the additives. The method allows the preparation of a diverse range of particle shapes: rod-like, with different aspect ratios (1a, 1b); triangular (1c); triangular with inscribed geometrical shapes (d); deformed and/or elongated triangular shapes (e, f); quadrilateral shapes (g, h); quadrilateral shapes with inscribed geometrical shapes (i); hexagonal (j); hexagonal with inscribed geometrical shapes (k, l); and/or polygonal shape (m).

Abstract: The present invention relates to a heat-insulating material, in particular in the form of a solid foam, based on silica particles of submicron porosity, this material incorporating two different ranges of porosities, advantageously including a first range consisting of (macro)pores with diameters of between 10 microns and 3 mm, and a second range consisting of submicron pores with diameters greater than 4 nm and less than 300 nm, the pore volume of said submicron pores being at least 1 cm3/g and the mass per unit volume of said insulating material being less than 300 kg/m3, and also relates to the process for obtaining the same.
