Patent number: 8663380Abstract: A flame spray pyrolysis process for the preparation of ultrafine titania particles coated with a smooth, homogeneous coating of one or more metal oxides is provided. The metal oxide coating is achieved by contacting the titania particles with a metal oxide precursor downstream of the titania formation zone, after the titania particles have formed. The process provides titania particles with a high rutile content and a smooth and homogeneous coating of a metal oxide.Type: GrantFiled: November 16, 2007Date of Patent: March 4, 2014Assignee: Cristal USA Inc.Inventors: M. Kamal Akhtar, Sotiris Emmanuel Pratsinis, Martin Christian Heine, Alexandra Teleki Harsanyi, Reto Strobel

Patent number: 8663381Abstract: A pigment is dispersed in a solvent by mixing the pigment nanoparticles with clay in a layered or platelet form and mixing the resultant mixture with the solvent. The method is based on geometric inhomogeneity and mutually exclusive aggregation. The layered or platelet clay having a high aspect ratio is provided to hinder aggregation of the pigment nanoparticles. The pigment nanoparticles can be stably dispersed in a matrix containing an organic solvent and water without aggregation again.Type: GrantFiled: July 18, 2008Date of Patent: March 4, 2014Assignee: National Taiwan UniversityInventors: Jiang-Jen Lin, Yi-Fen Lan, Yen-Chi Hsu

Patent number: 8663383Abstract: The invention provides an expansive material that allows for large expansion of concrete at a material age of 2 to 7 days after pouring and permits concrete to have higher initial compressive strength and makes sure good storage stability, and a process for preparing that expansive material. The invention provides an expansive material and a process for preparing that expansive material, characterized in that clinker or pulverized clinker containing free lime, a hydraulic compound and calcium sulfate anhydrite is heat treated in a carbon dioxide gas atmosphere to form calcium carbonate in it. Preferably, the expansive material contains a particle in which the free lime, hydraulic compound, calcium sulfate anhydrite and calcium carbonate are all present; the content of calcium carbonate is 0.5 to 10% by mass; and the expansive material has a Blaine's specific surface area of 1,500 to 90,000 cm2/g. The expansive material is blended with cement into a cement composition.Type: GrantFiled: May 20, 2010Date of Patent: March 4, 2014Assignee: Denki Kagaku Kogyo Kabushiki KaishaInventors: Takayuki Higuchi, Taiichiro Mori, Hideaki Ishida, Ryoetsu Yoshino, Minoru Morioka

Patent number: 8663387Abstract: A method and system for processing at least one portion of a thin film sample on a substrate, with such portion of the film sample having a first boundary and a second boundary. One or more first areas of the film sample are successively irradiated by first beamlets of an irradiation beam pulse so that the first areas are melted throughout their thickness and allowed to re-solidify and crystallize thereby having grains grown therein. Thereafter, one or more second areas of the film sample are irradiated by second beamlets so that the second areas are melted throughout their thickness. At least two of the second areas partially overlap a particular area of the re-solidified and crystallized first areas such that the grains provided in the particular area grow into each of the at least two second areas upon re-solidification thereof.Type: GrantFiled: March 9, 2006Date of Patent: March 4, 2014Assignee: The Trustees of Columbia University in the City of New YorkInventor: James S.
