摘要:
L'invention porte sur des microgels de poly(oligo-(éthylène glycol) méthacrylate), sur leur procédé de préparation et leurs utilisations dans différents domaines d'applications tels que l'optique, l'électronique, la pharmacie et la cosmétique. Ces microgels présentent l'avantage d'être monodisperses, pH-sensibles et thermosensibles. Ils peuvent véhiculer des nanoparticules magnétiques ou des molécules biologiquement actives. Ces microgels peuvent également former des films transparents, qui présentent des propriétés optiques et électromécaniques originales.
摘要:
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.

Methods of making a high gel strength, water-dispersible, stabilizing colloidal microcrystalline cellulose composition are disclosed. This stabilizer composition is useful in many food and non-food applications.
摘要:
There is set forth herein a method for providing a nanoparticle array. A nanoparticle network can be provided by nanoparticles combined with surfactant micelle chains. The nanoparticle network can be provided by distributing metal nanoparticles in a surfactant solution and agitating the surfactant solution comprising the nanoparticles to form a gel comprising the nanoparticle network which can be characterized by a distributed array of nanoparticles combined with surfactant micelle chains within a fluid. The gel can comprise a fluid in a continuous phase and the nanoparticles in a discontinuous phase. Apparatus having arrays of nanoparticles are also set forth herein.

A gel film or an isolated gel film comprising sheets of graphene or chemically converted graphene at least partially separated by a dispersion medium, such as water, and arranged in a substantially planar manner to form an electrically conductive matrix.
摘要:
Fluids viscosified with viscoelastic surfactants (VESs) may have their viscosities reduced (gels broken) by the direct or indirect action of a composition that contains at least one metal ion source and optionally at least one second source. An optional second source may be a chelating agent where at least one reducing agent source may be additionally optionally used. Another optional component with the metal ion source includes a second, different metal ion source. The breaking composition is believed to directly attack the VES itself, possibly by disaggregating or otherwise attacking the micellar structure of the VES-gelled fluid, and/or possibly by changing the chemical structure of the VES to give two or more products.
摘要:
This invention discloses electrified freeze-dried hydrocolloid gels, having modified structures with improved properties, as well as methods for the preparation of these modified gels and their uses. Specifically gels modified by electrification and freeze-drying undergo changes including creation of concentric layers of gel and intervening spaces.
