20090197426 | Process for Preparing a Dielectric Interlayer Film Containing Silicon Beta Zeolite - A process for forming a zeolite beta dielectric layer onto a substrate such as a silicon wafer has been developed. The zeolite beta is characterized in that it has an aluminum concentration from about 0.1 to about 2.0 wt. %, and has crystallites from about 5 to about 40 nanometers. The process involves first dealuminating a starting zeolite beta, then preparing a slurry of the dealuminated zeolite beta followed by coating a substrate, e.g. silicon wafer with the slurry, heating to form a zeolite beta film and treating the zeolite beta with a silylating agent. | 08-06-2009 |

20100260664 | Process for Preparing Nano Size Zeolites - A process has been developed to synthesize various zeolites with nano size crystals. The process involves forming an aluminosilicate initiator which exhibits the Tyndall effect and contains no appreciable filterable solids. This initiator is then mixed with a clear solution comprising reactive sources of Al, Si, M and R plus water. M is an alkali or alkaline earth metal while R is an organoammonium compound. The resultant reaction mixture is reacted at a temperature and for a time sufficient to produce a zeolite such as zeolite Y with average crystallite size less than 500 nm or preferably less than 300 nm. | 10-14-2010 |
20110138999 | METAL ORGANIC FRAMEWORK POLYMER MIXED MATRIX MEMBRANES - Metal-organic framework (MOF)-polymer mixed matrix membranes (MOF-MMMs) can be prepared by dispersing high surface area MOFs into a polymer matrix. The MOFs allow the polymer to infiltrate the pores of the MOFs, which improves the interfacial and mechanical properties of the polymer and in turn affects permeability. These mixed matrix membranes are attractive candidates for practical gas separation applications such as CO | 06-16-2011 |

20130005564 | SYNTHESIS OF CRYSTALLINE LONG-RANGED ORDERED MATERIALS FROM PREFORMED AMORPHOUS SOLIDS - Composites of a crystalline or long-ranged ordered material (CLROM), for example zeolites and non-zeolitic molecular sieves, are disclosed. The composites have both a macroscopic particle size (e.g., an average particle size of greater than about 0.1 mm), as desired in commercial applications, as well as improved functionality. Such composites result from the conversion of a conventional amorphous material, for example a solid amorphous silica alumina of this particle size, into the CLROM. According to particular embodiments, all or substantially all (e.g., at least about 99%) of the amorphous material is converted to the CLROM, such that essentially the entire macroscopic material may have the desired functionality of the CLROM as a catalyst or adsorbent. | 01-03-2013 |
