20080213883 | SILICA NANOPARTICLES IN BASIC AMINO ACID-SILICA SOLS - In general, in one aspect, the invention features a method that includes preparing a mixture comprising water, a basic amino acid, and a metal oxide precursor under conditions which result in the formation of metal oxide nanoparticles from the metal oxide precursor. | 09-04-2008 |
20110009256 | NOVEL MICROPOROUS SILICATE MATERIALS AND METHODS FOR MAKING AND USING THE SAME - With an amino acid as a buffer, a method is disclosed for producing a proton-exchanged three-dimensional layered silicate material. Additional embodiments include a method for producing a swollen proton-exchanged three-dimensional layered silicate material. This new material is a result of reactive swelling which accompanies one or more major changes of the layer structure. The materials can be further processed such as with exfoliation. The materials may be combined with polymers to produce film membranes such as thin film porous membranes. The membranes are useful in separating gases and as absorbents. | 01-13-2011 |
20110040013 | LAYERED ZEOLITE MATERIALS AND METHODS RELATED THERETO - A novel oxide material (MIN-I) comprising YO | 02-17-2011 |
20110047864 | METHOD AND APPARATUS FOR PRODUCING A FUEL FROM A BIOMASS OR BIO-OIL - Methods and reactors for producing a fuel are disclosed herein. In some embodiments, the method uses a biomass feedstock and alkane and/or alcohol feedstock, which can be contacted with a metal-containing catalyst to form products including a bio-oil. In some embodiments, oxygen-containing functional groups can be removed from a bio-oil using one or more zeolite thin films. | 03-03-2011 |
20130059722 | ONE-STEP SYNTHESIS OF MESOPOROUS PENTASIL ZEOLITE WITH SINGLE-UNIT-CELL LAMELLAR STRUCTURAL FEATURES - A method for making a pentasil zeolite material includes forming an aqueous solution that includes a structure directing agent and a silica precursor; and heating the solution at a sufficient temperature and for sufficient time to form a pentasil zeolite material from the silica precursor, wherein the structure directing agent includes a quaternary phosphonium ion. | 03-07-2013 |
20150376019 | SILICA SUPPORT STRUCTURE FOR A ZEOLITE MEMBRANE - A process for making a mechanically strong, high permeance, and relatively inexpensive support structure for zeolite membranes is described. In an example implementation, a process includes forming a silica powder from silica fibers, mixing the silica powder and a polymer solution to form a mixture, forming the mixture into a shaped mixture, and sintering the shaped mixture to form a silica support. | 12-31-2015 |
