Abstract: Nanofibers are fabricated by introducing a polymer solution into a dispersion medium and shearing the dispersion medium. Droplets of the polymer solution are spun into elongated fibers that are insoluble in the dispersion medium.

Abstract: Nanofibers are fabricated in a continuous process by introducing a polymer solution into a dispersion medium, which flows through a conduit and shears the dispersion medium. Liquid strands, streaks or droplets of the polymer solution are continuously shear-spun into elongated fibers. An inorganic precursor may be introduced with the polymer solution, resulting in fibers that include inorganic fibrils. The resulting composite inorganic/polymer fibers may be provided as an end product. Alternatively, the polymer may be removed to liberate the inorganic fibrils, which may be of the same or smaller cross-section as the polymer fibers and may be provided as an end product.

Abstract: Nanofibers are fabricated by introducing a mixture of a polymer solution and inorganic precursor into a dispersion medium and shearing the mixture. Liquid strands, streaks or droplets of the mixture are spun into elongated fibers that include inorganic fibrils. The resulting composite inorganic/polymer fibers may be provided as an end product. Alternatively, the polymer may be removed to liberate the inorganic fibrils, which may be of the same or smaller cross-section as the polymer fibers and may be provided as an end product.

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).
