Abstract: Aerosols can be created by filament stretching and breaking of Newtonian and non-Newtonian fluids by applying a strain to and stretching the fluid. The fluid is stretched along a strain pathway and forms a fluid filament. The fluid filament is caused to break into droplets that can be harvested to form a mist or aerosol. Such a system for aerosol creation can include a pair of counter-rotating rollers that are positioned adjacent to each other that stretch the fluid or a pair of pistons that move toward and away from each other to stretch the fluid.
Abstract: A method is disclosed of producing stable nanosized colloidal suspensions of particles with limited crystallinity loss, products thereof, use of the products and an apparatus for the method. In particular the present invention relates to a wet milling method with small beads wherein the size of the final particles in suspension are stabilized in the nanorange (D50<75 nm) and at the same time the particles substantially maintain the crystallinity.

The dispersants are also useful for preparing cationic titanium dioxide slurries.
Abstract: Disclosed is an emulsion formed using, as an emulsifier, 0.01 to 30 parts by weight of a perfluoroalkylethyl phosphonic acid salt represented by the general formula: CnF2n+1CH2CH2P(O)(OM1)(OM2) [III] (M1: a hydrogen atom, ammonium salt, or organic amine salt, M2: an ammonium salt or organic amine salt, n: 1 to 6), based on 100 parts by weight of a perfluoropolyether oil represented by the general formula: RfO(C3F6O)p(C2F4O), (CF2O), Rf? [I] (Rf and Rf?: C1-C5 perfluoroalkyl groups, p+q+r: 2 to 200) or the general formula: F(CF2CF2CF2O)nCF2CF3 [II](n: 2 to 100), or a perfluorocarbon compound. In spite of using, as an emulsifier, a compound having a perfluoroalkyl group containing 6 or less carbon atoms, which is said to have low bioaccumulation potential, the emulsion exhibits excellent emulsification stability, and therefore can be effectively used as a surface-treating agent, such as a mold-releasing agent.

Abstract: In one embodiment, an aerogel or xerogel includes column structures of a material having minor pores therein and major pores devoid of the material positioned between the column structures, where longitudinal axes of the major pores are substantially parallel to one another. In another embodiment, a method includes heating a sol including aerogel or xerogel precursor materials to cause gelation thereof to form an aerogel or xerogel and exposing the heated sol to an electric field, wherein the electric field causes orientation of a microstructure of the sol during gelation, which is retained by the aerogel or xerogel. In one approach, an aerogel has elongated pores extending between a material arranged in column structures having structural characteristics of being formed from a sol exposed to an electric field that causes orientation of a microstructure of the sol during gelation which is retained by the elongated pores of the aerogel.
