Publication number: 20230332319Abstract: A method for selectively recovering a rare earth element (REE) from an alloy includes applying a potential of from -3.5 V to 0 V to an electrochemical cell comprising a anode, a cathode, and an electrolyte, wherein (i) the anode comprises an alloy comprising a REE, (ii) the cathode comprises a noble metal, and (iii) the electrolyte comprises an alkali metal or alkaline earth metal salt and a nonaqueous solvent. Under the applied potential, at least some of the REE is oxidatively dissolved from the anode and is electrodeposited onto the cathode to form an REE deposit.Type: ApplicationFiled: April 13, 2023Publication date: October 19, 2023Applicant: Battelle Memorial InstituteInventors: Hyung-Seok Lim, Wei Wang, Vijayakumar Murugesan, Chinmayee Venkata Subban, Tasya S.

Patent number: 10715797Abstract: The present invention relates to a device for testing an angle of view of a camera. The present invention may comprise: a first light source which is arranged to face an image sensor, and has a first width and a second width longer than the first width; and a second light source and a third light source which are disposed on both sides of the image sensor in the direction of the first width, respectively. The present invention can inhibit an interference of the light source or a bracket supporting the light source by reducing the number of light sources. In addition, since it is possible to measure the angle of view of a camera by reducing the light sources, the present invention can reduce the manufacturing costs of a device for testing an angle of view of a camera.Type: GrantFiled: May 28, 2019Date of Patent: July 14, 2020Assignee: LG INNOTEK CO., LTD.Inventors: Dae Sang Ryu, Kyoung Chan Park, Yong Su Lee, Hyung Seok Lim

Patent number: 9096797Abstract: A silicate phosphor composition is provided having a ?-phase of an orthorhombic crystal structure whose space group is Pbnm 62, and whose composition is represented by the following chemical formula: Ca2-x-y-zMxSiO4:yCe3+,zN(0?x<0.5,0<y?0.1,0?z<0.15) In the formula, M represents at least one member selected from the group consisting of Mg, Sr, Ba, Zn, Na, Al, Ga, Ge, P, As and Fe, and N represents at least one member selected from the group consisting of Eu2+, Mn2+, Tb3+, Yb2+ and Tm3+. The silicate phosphor has a maximum absorbance for a wavelength of about 450 nm to about 475 nm corresponding to a main part of a blue excitation light, and has a great stability at a high temperature. As such the silicate phosphor may be used in combination with a blue light source to produce a white light.Type: GrantFiled: May 3, 2012Date of Patent: August 4, 2015Assignees: SAMSUNG DISPLAY CO., LTD., PU-LYONG NATIONAL UNIVERSITY INDUSTRY—UNIVERSITY FOUNDATIONInventors: Myeong-Ju Shin, Seung-Hwan Baek, Yeong-Bae Lee, Young-Sic Kim, Seok-Hyun Nam, Byung-Choon Yang, Jong-Su Kim, Kwang-Won Park, Yun-Hyoung Park, Ji-Su Yu, Hyung-Seok Lim
