20080207808 | Novel mechanism for immiscible polymer blend compatibilization - A method of compatibilizing immiscible polymers using the mechanical deformation of quaternary amine treated organoclay particles is described. The mechanism decreases the interstitial energy resulting from immiscible polymer domain interfaces into stored mechanical energy. The polymer domains in the immiscible blend get smaller and the resulting compatibilized microcomposite/nanocomposite blend has superior mechanical properties over non compatibilized blends controls of the same materials. | 08-28-2008 |
20090306261 | Compatibilizing Polymer Blends by Using Organoclay - A method for producing a polymer blend that includes: combining a first polymer, a second polymer and an organoclay to form a mixture, wherein the first polymer is not compatible with the second polymer, and heating the polymer and organoclay mixture to form a compatilized polymer blend. The preferred organoclay is montmorillonite clay functionalized by an intercalation agent. The intercalation agent is a reaction product of a polyamine and an alkyl halide in a polar solvent. | 12-10-2009 |
20100152348 | Nanocompatibilized novel polymer blends - Compatibilized blends of two or more polymers may be formed using a quaternary amine treated organoclay. The quaternary amine treated organoclay may be a cloisite. A wide variety of polymeric blends may be formed. Such blends may include polyvinylchloride, ethylene vinyl, acetate, polymethyl methacrylate, styrene acrylonitrile copolymer, polycaprolactone, etc. | 06-17-2010 |
20110275572 | Nanocomposite Hyaluronic Acid-Clay Based Hydrogels - Hydrogels formed from hyaluronic acid, a nanoclay and gelatin-type A. The hyaluronic acid is preferably dissolved in a cell culture medium containing amino acids, salts, glucose, vitamins and an antibiotic to form a hyaluronic acid solution. The gelatin-type A has a weight/volume of from about 0.02% to 0.08%. The nanoclay is exfoliated in deionized water and preferably includes SiO | 11-10-2011 |
20110281035 | CHEMICAL SYNTHESIS FOR GRAPHENE SHEETS GREATER THAN 1 um IN LENGTH - A method for preparing a graphene sheet greater than 1 μm in length that includes: combining graphitic oxide with a solvent having a ratio of from about 50:50 to about 80:20 deionized water and ethanol to form a graphitic oxide solution; mixing a solution of NaBH | 11-17-2011 |
20120186822 | MODULAR PRESSURE MANAGEMENT OIL SPILL CONTAINMENT SYSTEM AND METHOD - A modular pressure management oil spill containment system is constructed on the floor of an ocean to contain an oil spill caused by a wild well blowout. A base containment module including a hollow wall and at least one pressure relief valve is submerged below a surface of the ocean, positioned on a portion of the ocean floor that circumvents the wild well and its hollow wall is reinforced. At least one additional containment module including a hollow wall and at least one pressure relief valve is submerged below the ocean surface, positioned on top of the base containment module and its hollow wall is also reinforced. A plurality of riser assemblies are connected between at least a portion of the pressure relief valves of the containment modules and at least one containment vessel. The pressure relief valves are controlled to manage the containment of the oil spill. | 07-26-2012 |
20120282305 | BIOLOGICAL SURFACTANTS FOR CONNECTION TO SILICONE-BASED MATERIALS AND MODULATING LEVELS OF IMMUNOLOGICALLY ACTIVE PROTEINS - Biological surfactants connected to surfaces of silicone-based materials are provided. Compositions of electrolytes and a biological surfactant are also provided. Methods for increasing the surface wettability of a silicone-based material by contacting the silicone-based material with a biological surfactant, methods for increasing evaporation from a silicone-based material by contacting a surface of the silicone-based material with a biological surfactant, methods for increasing levels of interleukin-8 during inflammation by contacting a cell with a biological surfactant, and methods for decreasing expression of a biological surfactant by contacting a cell with an siRNA are further provided. | 11-08-2012 |
20130123647 | Methods Useful in Optimizing the Treatment of Neuropathies and Targeting Tissues with Cosmetic Botulinum Injections - The present invention pertains to methods of determining where, on the skin, a diagnostic, therapeutic, or cosmetic agent is likely to be most effectively applied (e.g., injected), and to methods for monitoring a patient after such an agent has been administered. The monitoring can produce information useful in determining whether a diagnostic, therapeutic (e.g., surgical), or cosmetic regime should be initiated, continued, continued in a modified fashion, or terminated (e.g., for a brief or prolonged period of time). The methods can be repeated periodically and use a non-invasive, in vivo form of digital image speckle correlation (DISC) to track deformation of the skin. | 05-16-2013 |
