Patent number: 10035139Abstract: The present invention discloses a method for improving solar energy conversion efficiency using metal oxide photocatalysts having an energy band of core-shell structure for ultraviolet (UV) ray and visible light absorption, comprising a first process of forming a nanoparticle thin film layer; a second process of preparing a core-shell metal oxide on metal oxide nanoparticles by a plasma reaction under a hydrogen and nitrogen gas atmosphere, and a third process of depositing a transition metal on surfaces of core-shell metal oxide nanoparticles to produce a photocatalyst for energy conversion. A great amount of oxygen vacancies is formed in a shell region by the core-shell metal oxide to achieve effects of improving transfer ability of electron-hole pairs excited by light, and extending a wavelength range of absorbable light to a visible light region by changing a band-gap structure.Type: GrantFiled: June 28, 2016Date of Patent: July 31, 2018Assignee: Korea Advanced Institute of Science and TechnologyInventors: Jeung Ku Kang, Dong Ki Lee, Gyu Heon Lee, Yong-Hoon Kim, Ji Ii Choi

Patent number: 8894920Abstract: A method for making a thin, free-standing ceramic sheet may include drawing a carrier film proximate a casting head and across a casting bed of a tape caster at a rate from about 2 cm/min to about 500 cm/min. Depositing a thin film of ceramic slip less than about 150 ?m on the carrier film with the casting head. The ceramic slip may comprises a ceramic powder with an ultimate crystallite size of less than about 10 ?m dispersed in a fluid vehicle such that the ceramic slip has a ceramic solids fraction of greater than about 20% by volume. The deposited ceramic slip may be dried on the carrier film thereby forming a green ceramic sheet on the carrier film. After the green ceramic sheet is dried, the green ceramic sheet may be sintered.Type: GrantFiled: October 29, 2009Date of Patent: November 25, 2014Assignee: Corning IncorporatedInventors: Lanrik Kester, Thomas Dale Ketcham, Brian Scott Kirk, Dell Joseph St Julien

Patent number: 7303723Abstract: A method for manufacturing oriented arrays of ceramic or metal oxide nanostructures, such as titania (TiO2) nanofibers. The nanofibers are formed on the surface of a body that is first sintered at a temperature in the range of about 1,100 to about 1,400 degrees Celsius. Subsequently, the surface is exposed to an H2-bearing gas, such as H2 and N2 in a ratio of about 5:95 at about 700 degrees Celsius for about 8 hours. During heat treatment in the gas phase reaction, sintered titania grains transform into arrays of nanofibers oriented in the same crystallographic direction.Type: GrantFiled: October 3, 2003Date of Patent: December 4, 2007Assignee: The Ohio State University Research FoundationInventors: Sheikh A.

Patent number: 7018583Abstract: According to a known method for producing a component by means of a powdery starting material, powder is mixed with auxiliaries comprising binding agents, whereby a free-flowing mass is produced. A green body is produced from the mass by means of powder injection moulding. A portion of the auxiliaries is extracted by heating the green body in a container and exposing said body to a stream of solvents. The green body is sintered, whereby the component is produced. The aim of the invention is to enable fast and gentle extraction for releasing green bodies which are produced by means of powder injection moulding. According to the invention, the extraction comprises a heating-up phase during which the temperature of the green body is permanently or gradually increased and the green body is overflown by solvent in the form of a compressed, supercritical treatment gas.Type: GrantFiled: March 30, 2001Date of Patent: March 28, 2006Assignee: Messer Griesheim GmbHInventors: Thomas Berger, Henry Cohrt, Heribert Dierkes
