Synthetic versions of the zeolites harmotome, heulandite, brewsterite and gmelinite are synthesized from Y-zeolite using alkaline earth cations containing solutions. The effect of the composition of the starting zeolite, the composition of the solution phase, the presence or absence of seeds and the experimental conditions are discussed.

专利号:US-2011111962-A1 优先权日:2007-07-23 标 题 :Improvements in magnesium diboride superconductors and methods of synthesis 发明人:WANG XIAOLIN; DOU SHI XUE; HOSSAIN MD SHAHRIAR AL; CHENG ZHENXIANG 权利人:UNIV WOLLONGONG 摘要:Improved magnesium diboride superconducting materials and methods of synthesis are disclosed. Embodiments of the superconducting material comprise at least two starting materials capable of forming MgB 2 and at least one dopant compound comprising silicon, carbon, hydrogen and oxygen. The starting materials and the at least one dopant compound are heated and mixed at an atomic level to produce a silicon-doped MgB 2 superconducting material. Examples of the dopant compound include silicone oil, Triacetoxy(methyl)silane ( 2 ), 1,7-Dichloro-octamethyltetrasiloxane ( 2 ) and Tetramethyl orthosilicate ( 6 ).
专利号:US-8758653-B2 优先权日:2009-06-02 标 题 :Molecular optimization of multiply-functionalized mesostructured materials 发明人:CHMELKA BRADLEY F; ATHENS GEORGE L; MESSINGER ROBERT 权利人:CHMELKA BRADLEY F; ATHENS GEORGE L; MESSINGER ROBERT; UNIV CALIFORNIA 摘要:A material and method for producing mesostructured materials with multiple functionalities that are independently adjustable and collectively optimizable is provided. The method uses a series of discrete synthesis steps under otherwise mutually incompatible conditions, e.g., from acidic, alkaline, and/or non-aqueous solutions, allows different functionalities to be introduced to the materials and optimized. To illustrate the method, cubic mesoporous silica films were prepared from strongly acidic solutions that were separately functionalized under highly alkaline conditions to incorporate hydrophilic aluminosilica moieties and under non-aqueous conditions to introduce perfluorosulfonic-acid surface groups.
专利号:US-10343926-B1 优先权日:2016-08-22 标题 :Synthesis of hierarchical zeolites by solid state crystallization of aluminosilicate nanogels 发明人:WANG SHENGNIAN; WANG YUXIN 权利人:LOUISIANA TECH RES CORPORATION 摘要:Hierarchically porous ZSM-5 zeolites, having macropores, mesopores, and micropores are formed using a solid-state crystallization process. An aluminosilicate nanogel prepared with precursors, solvent, and a structure-directing agent is provided. The solvent is evaporated from the aluminosilicate nanogel at room temperature. The dried aluminosilicate nanogel is then heated to promote crystallization. The crystallized zeolites are calcined to remove the structure-directing agent.
