Patent number: 10576462Abstract: A process for preparing a mesoporous material, e.g., transition metal oxide, sulfide, selenide or telluride, Lanthanide metal oxide, sulfide, selenide or telluride, a post-transition metal oxide, sulfide, selenide or telluride and metalloid oxide, sulfide, selenide or telluride. The process comprises providing an acidic mixture comprising a metal precursor, an interface modifier, a hydrotropic or lyotropic ion precursor, and a surfactant; and heating the acidic mixture at a temperature and for a period of time sufficient to form the mesoporous material. A mesoporous material prepared by the above process. A method of controlling nano-sized wall crystallinity and mesoporosity in mesoporous materials.Type: GrantFiled: May 8, 2014Date of Patent: March 3, 2020Assignee: University of ConnecticutInventors: Steven L.

Patent number: 10081006Abstract: The disclosure relates to a method for removing sulfur-containing compounds from a fluid. The method involves adding manganese oxide to the fluid; doping the manganese oxide in situ with iron, cobalt, or combinations thereof to give a doped manganese oxide adsorbent; and contacting the fluid with a selected amount of the doped manganese oxide adsorbent and at a selected temperature and pressure sufficient for the doped manganese oxide adsorbent to preferentially adsorb the sulfur-containing compounds in the fluid. The disclosure also relates to a process for preparing a doped manganese oxide adsorbent, and a doped manganese oxide adsorbent prepared by the process. The disclosure further relates to a method for tuning structural properties (e.g., surface area, pore size and pore volume) of a doped manganese oxide adsorbent.Type: GrantFiled: December 17, 2015Date of Patent: September 25, 2018Assignee: University of ConnecticutInventors: Steven L.

Patent number: 9107301Abstract: A foldable electronic device includes a first body, a second body and a hinge body. The hinge body is pivoted to the first body around a first pivoting axis and pivoted to the second body around a second pivoting axis so that the first body is able to rotate relatively to the second body. When the first body rotates to a first position relatively to the second body, a first front surface of the first body is closed to a second front surface of the second body on a closing plane, and a pivoting plane where the first pivoting axis and the second pivoting axis are located on and the closing plane are oblique to each other.Type: GrantFiled: November 28, 2012Date of Patent: August 11, 2015Assignee: COMPAL ELECTRONICS, INC.Inventors: Hung-Sung Pan, Chung-Hao Kuo, Jui-Wen Chou, Hung-Jui Lin, Tzu-Chien Lai, Hsin Yeh, Long-Cheng Chang, Chuang-Yueh Chen, Po-Chin Yu, Chuan-Hao Wen, Yung-Hsiang Chen, Ting-Wei Wu, Hui-Lian Chang, Ming-Wang Lin, Jui-Yuan Lee

Publication number: 20150130666Abstract: An assembled wearable electronic device includes a first body, a second body and an engaging assembly. The first body has a primary system for providing the independent operation of the first body and producing a related first data. The second body has a secondary system and a fixing assembly. The secondary system is for providing the independent operation of the second body and producing a related second data. The engaging assembly is disposed at one of the first and second bodies. When the engaging assembly is located at a first position, the first and second bodies contact each other to be combined through the engaging assembly. When the engaging assembly moves to a second position, the first and second bodies are configured to be separated from each other. When the first and second bodies are connected to each other, the second data is read by the primary system.Type: ApplicationFiled: April 30, 2014Publication date: May 14, 2015Applicant: COMPAL ELECTRONICS, INC.Inventors: Hung-Sung Pan, Chung-Hao Kuo, Chun-Liang Wu, Hung-Jui Lin, Cheng-Hsien Hsieh, Long-Cheng Chang, Chin-Kuo Huang, Yen-Hao Yu, Jhin-Ciang Chen, Shih-Chia Liu, Li-Chun Lee, Chang-Hua Wei, Ting-Wei Wu, Pei-Pin Huang, Pei-Jen Lin
