Publication number: 20240113388Abstract: Lithium-sulfur (Li—S) batteries using unconventional-phase transition metal dichalcogenides (TMDs), such as 1T?-WS2, as the functional layer on the separator. The unique atomic structure of 1T?-WS2 facilitates the strong immobilization and excellent catalytic ability in the conversion of polysulfide intermediates during cycling. Furthermore, the self-assembling of 1T?-WS2 greatly decreases the internal porosity, minimizing the uptake of electrolyte, which can further guarantee the performance of the battery under lean electrolyte conditions. As a result, a cell based on the 1T?-WS2 shows improved performances under high sulfur loading and lean electrolyte conditions. A cell with 12 mg cm?2 mass loading of S with only 25% oversized Li metal anode can deliver specific energy of at least 400 Wh kg?1 and 820 Wh L?1, which is among the best of reported Li—S batteries.Type: ApplicationFiled: September 27, 2023Publication date: April 4, 2024Inventors: Hua ZHANG, Zijian ZHENG, Zhuangchai LAI, Lei WANG

Publication number: 20200293536Abstract: Architecture that decomposes of one or more monolithic data concepts into atomic concepts and related atomic concept dependencies, and provides streaming data processing that processes individual or separate (atomic) data concepts and defined atomic dependencies. The architecture can comprise data-driven data processing that enables the plug-in of new data concepts with minimal effort. Efficient processing of the data concepts is enabled by streaming only required data concepts and corresponding dependencies and enablement of the seamless configuration of data processing between stream processing systems and batch processing systems as a result of data concept decomposition. Incremental and non-incremental metric processing enables realtime access and monitoring of operational parameters and queries.Type: ApplicationFiled: March 12, 2020Publication date: September 17, 2020Applicant: Microsoft Technology Licensing, LLCInventors: Wei Lu, Michael Kinoti, Shengquan Yan, Peng Yu, Xian Zhang, Guixi Zou, Yin He, Xavier Drudis Rius, Miriam Rosenberg, Zijian Zheng

Patent number: 10366131Abstract: The concepts relate to task completion and specifically to aiding a user to complete an unfinished task at a subsequent time and/or on another device. One example can identify that a user is working on a task on a computing device associated with the user. In an instance when the user stops using the computing device without completing the task, the example can predict a likelihood that the user will subsequently resume the task on a second computing device associated with the user. In an instance where the likelihood exceeds a threshold, the example can attempt to aid the user in completing the task on the second computing device.Type: GrantFiled: May 20, 2016Date of Patent: July 30, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Ryen W.
