Patent number: 8304465Abstract: A method for the preparation of high strength air-dried organic aerogels. The method involves the sol-gel polymerization of organic gel precursors, such as resorcinol with formaldehyde (RF) in aqueous solvents with R/C ratios greater than about 1000 and R/F ratios less than about 1:2.1. Using a procedure analogous to the preparation of resorcinol-formaldehyde (RF) aerogels, this approach generates wet gels that can be air dried at ambient temperatures and pressures. The method significantly reduces the time and/or energy required to produce a dried aerogel compared to conventional methods using either supercritical solvent extraction. The air dried gel exhibits typically less than 5% shrinkage.Type: GrantFiled: January 18, 2006Date of Patent: November 6, 2012Assignee: Lawrence Livermore National Security, LLCInventors: Paul R. Coronado, Joe H. Satcher, Jr.

Patent number: 8303883Abstract: The invention provides foams of desired cell sizes formed from metal or ceramic materials that coat the surfaces of carbon foams which are subsequently removed. For example, metal is located over a sol-gel foam monolith. The metal is melted to produce a metal/sol-gel composition. The sol-gel foam monolith is removed, leaving a metal foam.Type: GrantFiled: June 30, 2006Date of Patent: November 6, 2012Assignee: Lawrence Livermore National Security, LLC.Inventors: Richard L. Landingham, Joe H. Satcher, Jr., Paul R. Coronado, Theodore F. Baumann

Patent number: 7803737Abstract: Solid materials have been developed to remove arsenic compounds from aqueous media. The arsenic is removed by passing the aqueous phase through the solid materials which can be in molded, granular, or powder form. The solid materials adsorb the arsenic leaving a purified aqueous stream. The materials are aerogels or xerogels and aerogels or xerogels and solid support structure, e.g., granulated activated carbon (GAC), mixtures. The species-specific adsorption occurs through specific chemical modifications of the solids tailored towards arsenic.Type: GrantFiled: June 6, 2008Date of Patent: September 28, 2010Assignee: Lawrence Livermore National Security, LLCInventors: Paul R. Coronado, Sabre J. Coleman, Robert D. Sanner, Victoria L. Dias, John G. Reynolds

Patent number: 7211605Abstract: An aerogel material with surfaces containing fluorine atoms which exhibits exceptional hydrophobicity, or the ability to repel liquid water. Hydrophobic aerogels are efficient absorbers of solvents from water. Solvents miscible with water are separated from it because the solvents are more volatile than water and they enter the porous aerogel as a vapor across the liquid water/solid interface. Solvents that are immisicble with water are separated from it by selectively wetting the aerogel. The hydrophobic property is achieved by formulating the aerogel using fluorine containing molecules either directly by addition in the sol-gel process, or by treating a standard dried aerogel using the vapor of fluorine containing molecules.Type: GrantFiled: March 4, 2004Date of Patent: May 1, 2007Assignee: The Regents of the University of CaliforniaInventors: Paul R.

Patent number: 7148180Abstract: Functionalized hydrophobic aerogel/solid support structure composites have been developed to remove metals and organic compounds from aqueous and vapor media. The targeted metals and organics are removed by passing the aqueous or vapor phase through the composite which can be in molded, granular, or powder form. The composites adsorb the metals and the organics leaving a purified aqueous or vapor stream. The species-specific adsorption occurs through specific functionalization of the aerogels tailored towards specific metals and/or organics. After adsorption, the composites can be disposed of or the targeted metals and/or organics can be reclaimed or removed and the composites recycled.Type: GrantFiled: March 4, 2004Date of Patent: December 12, 2006Assignee: The Regents of the University of CaliforniaInventors: Paul R.

Patent number: 6998102Abstract: A process for making transparent porous glass monoliths from gels. The glass is produced much faster and in much larger sizes than present technology for making porous glass. The process reduces the cost of making large porous glass monoliths because: 1) the process does not require solvent exchange nor additives to the gel to increase the drying rates, 2) only moderate temperatures and pressures are used so relatively inexpensive equipment is needed, an 3) net-shape glass monoliths are possible using this process. The process depends on the use of temperature to control the partial pressure of the gel solvent in a closed vessel, resulting in controlled shrinking during drying.Type: GrantFiled: September 23, 2002Date of Patent: February 14, 2006Assignee: The Regents of the University of CaliforniaInventor: Paul R.

Publication number: 20040173536Abstract: A device that absorbs and separates oil from oil-water mixtures. The device is formed by combining an absorbent material with a support. The absorbent material is a hydrophobic sol-gel material processed to be an aerogel, with the support being a material of any type that can give the absorbent a place to reside. The absorbent or aerogel material may be coated onto or otherwise secured to the support material. When an oil-water mixture contacts the aerogel material, preferably in granulated or powdered form, the aerogel material will preferentially absorb and retain the oil phase, rejecting the water phase of the mixture. The end result is two separated streams, an oil only stream, and a water only stream.Type: ApplicationFiled: March 4, 2004Publication date: September 9, 2004Applicant: The Regents of the University of CaliforniaInventors: Paul R.

Publication number: 20040142168Abstract: Fibers, and fabrics produced from the fibers, are made water repellent, fire-retardant and/or thermally insulating by filling void spaces in the fibers and/or fabrics with a powdered material.

Publication number: 20040056376Abstract: A method for preparing precursors for producing high density monolithic aerogels. The method enables fabrication of transparent porous glass monoliths, with the porosity or density controlled by adjusting the ratio of water to monomer. By this adjustment, syneresis is increased or minimized. The method involves either a single step precursor or a two step precursor where a base is added to the single step precursor after hydrolysis has occurred. Monolithic metal oxide aerogels with densities between 0.3 g/cc to 1.5 g/cc have been produced using this method.Type: ApplicationFiled: September 23, 2002Publication date: March 25, 2004Applicant: The Regents of the University of CaliforniaInventor: Paul R.

Patent number: 6709600Abstract: A method for removing organic liquids from aqueous solutions and mixtures. The method employs any porous material preferably in granular form and having small pores and a large specific surface area, that is hydrophobic so that liquid water does not readily wet its surface. In this method, organics, especially organic solvents that mix with and are more volatile than water, are separated from aqueous solution by preferentially evaporating across the liquid/solid boundary formed at the surfaces of the hydrophobic porous materials. Also, organic solvents that are immiscible with water, preferentially wet the surfaces of the hydrophobic material and are drawn within the porous materials by capillary action.Type: GrantFiled: September 21, 2001Date of Patent: March 23, 2004Assignee: The Regents of the University of CaliforniaInventors: Lawrence W.
