A process for treating a tailings stream comprises (a) contacting a deionized silicate solution with a tailings stream whereby the solids are entrapped within a gel produced from the silicate solution; and (b) allowing the gel to strengthen and solidify. The process may further comprise spreading the gel produced in step (a) over a surface. The present invention is particularly useful to treat tailings streams produced in processes to extract bitumen from oil sands ores. |

This invention relates to processes of preparing structured polymer matrix using two or more simultaneous multiple acervation mechanisms. In addition, the methods described herein provide flexible processes for forming structured polymer matrices from nearly any combination of polymers, preferably, although not limited to, food polymers. The simultaneous application of two or more acervation mechanisms unexpectedly gives novel matrices having improved texture and/or process efficiency that are superior to the polymer matrices produced by acervation mechanisms conducted individually or sequentially. |

A wet silica gel can be prepared by a process comprising the steps of contacting a stable, aqueous, fluid, silica system having a pH greater than 7.5 with an ion exchange resin which removes metal ions and replaces them with H+ ions and thereby reduces the pH to less than 5.0, adding an organic liquid to the aqueous silica system, providing, however, that the organic liquid added stays in one phase with the aqueous, silica, system, and does not cause the silica to precipitate, and adding a base to the silica system so that the pH of the silica system is in the range of from about 5.0 to about 7.5, and allowing the wet silica gel to form. The wet silica gel formed by this process is characterized by its high organic solvent content and the low concentration of basic metal ions. |

A method of treating a metal alkoxide solution to form metal oxide prepolymer molecules therein is characterized by irradiating the solution with light energy having a wavelength selected to break the metal-alkoxy group bond in said metal alkoxide, thereby to form the metal oxide prepolymer molecules in the solution. The prepolymer is converted into polymeric metal oxide gel. The stoichiometry of the oxide is high. A gel of carbon content below 4 atomic % can be achieved by the step of decarbonizing the gel, preferably using light to produce ozone. |

A dried gel material sterically entrapping nanoclusters of a catalytically active material and a process to make the material via an inverse micelle/sol-gel synthesis. A surfactant is mixed with an apolar solvent to form an inverse micelle solution. A salt of a catalytically active material, such as gold chloride, is added along with a silica gel precursor to the solution to form a mixture. To the mixture are then added a reducing agent for the purpose of reducing the gold in the gold chloride to atomic gold to form the nanoclusters and a condensing agent to form the gel which sterically entraps the nanoclusters. The nanoclusters are normally in the average size range of from 5-10 nm in diameter with a monodisperse size distribution. |

A microemulsion gel having antiseptic and bleaching properties is prepared from the combination of a water phase comprising water and propylene glycol with an oil phase generally comprising one or more surfactants, an emollient, and an oil. In its preferred embodiment, the oil phase comprises a polyethylene glycol ether of isocetyl alcohol, preferably Isoceteth-20, a polyethylene glycol ether of oleyl alcohol, preferably Oleth-2, and a polypropylene glycol ether of stearyl alcohol, preferably PPG-15 stearyl ether. The water phase optionally includes sorbitol and the oil of the oil phase may be mineral oil. The water and oil phases are heated independently then combined and mixed. Hydrogen peroxide is subsequently added to the composition, and the combination is cooled and allowed to stand until a gel is formed. A fragrance may be added as desired. |

What is provided herein is a stable, emulsifiable gel matrix for an agriculturally active chemical, which matrix will form an emulsifiable gel concentrate upon addition of the agriculturally active chemical, and upon water dilution, a highly stable aqueous macroemulsion which avoids precipitation of the active ingredient on extended storage. In addition, the inventive emulsifiable gel concentrates may contain relatively high concentrations of the agriculturally active chemical, the concentration sometimes referred herein to as "loading", making it advantageous from both the economic and handling viewpoints. |
