Patent number: 11958038Abstract: A group of reductive 2D materials (R2D) with extended reactive vacancies and a method for making the R2D with extended reactive vacancies are provided, especially the example of the reductive boron nitride (RBN). To create defects such as vacancies, boron nitride (BN) powders are milled at cryogenic temperatures. Vacancies are produced by milling, and the vacancies can be used to reduce various metal nanostructures on RBN. Due to the thermal stability of the RBN and the enhanced catalytic performance of metal nanostructures, RBN-metals can be used for different catalysts, including electrochemical catalysts and high temperature catalysts.Type: GrantFiled: June 11, 2021Date of Patent: April 16, 2024Assignee: The Penn State Research FoundationInventors: Mauricio Terrones, Yu Lei, He Liu, Kazunori Fujisawa, Ana Laura Elias Arriaga, Tianyi Zhang, Rodolfo Cruz-Silva, Morinobu Endo, Xiaoxing Wang, Cynthia Guerrero-Bermea

Publication number: 20240089405Abstract: A best available video stream is determined for each of multiple conference participants within a conference room including multiple cameras based on scores determined for video streams obtained from the cameras. The scores are determined based on representations of the conference participants within the video streams, for example, based on percentages of conference participant faces visible within the video streams, directions of conference participant faces relative to the cameras, directions of eye gaze of the conference participants relative to the cameras, and/or degrees to which conference participant faces are obscured within the video streams. The best available video streams are output for rendering within separate user interface tiles of conferencing software.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Inventors: Anna Deng, Yanjia Duan, Juntao Feng, Tianming Gu, Cynthia Eshiuan Lee, Bo Ling, Chong Lv, Jeffrey William Smith, Menglin Wang, Huixi Zhao, Xingguo Zhu

Patent number: 8911179Abstract: The invention relates to a jack-up rig. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with a lower portion that is an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration. Furthermore, the jack-up rig comprises at least two derricks.Type: GrantFiled: February 14, 2012Date of Patent: December 16, 2014Assignees: ConocoPhillips Company, Keppel Offshore & Marine TechnologyInventors: Peter G.

Publication number: 20130101357Abstract: The invention relates to an ice worthy jack-up rig that may extend the drilling season in shallow water off shore Arctic or ice prone locations. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with a lower portion that is an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration. Furthermore, the ice worthy jack-up rig that comprises at least two derricks so as to double the exploration efficiency and lower the relating costs.Type: ApplicationFiled: February 14, 2012Publication date: April 25, 2013Applicants: Keppel Offshore & Marine Technology Centre PTE Ltd., ConocoPhillips CompanyInventors: Peter G.
