Publication number: 20240066182Abstract: The present disclosure provides a fiber membrane and a preparation method and use thereof, and belongs to the field of biological materials. The fiber membrane includes a fiber with a core-shell structure, where a core of the fiber includes simvastatin and a first spinnable polymer, and a shell of the fiber includes hydroxyapatite and a second spinnable polymer. In the fiber, a release of the simvastatin mainly depends on a rate of water invasion. After water invades the fiber, the simvastatin in the fiber leaves the fiber with the diffusion of water. In the present disclosure, a barrier function of the shell prevents moisture from entering the core. Therefore, the simvastatin in the core cannot leave the fiber with the diffusion of water molecules in an early stage, and a release rate of drugs is slowed down in the early stage, thereby controlling sustained release of the drugs.Type: ApplicationFiled: November 10, 2022Publication date: February 29, 2024Applicant: SHANGHAI RUIZHIKANG MEDICAL TECHNOLOGY CO., LTD.Inventors: Xiaohong CHEN, Yubo LIU, Honglei ZHOU, Wei LI, Fengcang MA, Shaoli FU, Guosen SHAO, Haochen WU

Publication number: 20240066177Abstract: The present disclosure provides a hydrophilic fiber membrane with a sustained-release drug, and belongs to the field of biological materials. The present disclosure provides a hydrophilic fiber membrane with a sustained-release drug, including a fiber with a core-shell structure, where a core of the fiber includes curcumin and a first spinnable polymer, and a shell of the fiber includes polyethylene glycol and a second spinnable polymer; and in the shell, the polyethylene glycol and the second spinnable polymer have a mass ratio of not greater than 1:12. In the present disclosure, the fiber membrane has a core-shell structure, the curcumin is provided in the core, and the shell prevents a rapid release of the curcumin in an early stage, thereby delaying a release rate of the curcumin to prevent the drug from forming a burst release in the early stage and causing toxic reactions.Type: ApplicationFiled: November 11, 2022Publication date: February 29, 2024Applicant: SHANGHAI RUIZHIKANG MEDICAL TECHNOLOGY CO., LTD.Inventors: Xiaohong CHEN, Yubo LIU, Honglei ZHOU, Wei LI, Fengcang MA, Shaoli FU, Guosen SHAO, Haochen WU

Publication number: 20240070603Abstract: A grid is created for a map of a geographic region based on a location planning request received from a user device. A plurality of candidate cells are identified from among a plurality of cells of the grid. Each of the candidate cells including a candidate location for a warehouse. Respective isochrones are generated relative to the candidate locations of the plurality of candidate cells based on a delivery time threshold indicated in the location planning request. Respective isochrone scores are determined for the generated isochrones based at least on data indicating a past volume of sales in the isochrone. Based on the respective isochrone scores of the candidate locations, a subset of the candidate locations is selected as a recommended set of locations for warehouses to cover the geographic region. A notification indicating the recommended set of locations is transmitted to the user device.Type: ApplicationFiled: August 31, 2022Publication date: February 29, 2024Inventors: Jagannath Putrevu, Haochen Luo, Xiangpeng Li, Rishab Saraf

Publication number: 20220404171Abstract: Disclosed is linear displacement absolute position encoder used for measuring displacement of a tested apparatus. The linear displacement absolute position encoder comprises a base, a magnetoresistive sensor array, an encoding strip, and a back magnet. The encoding strip is fixed on the base and extends in the direction of a rail of the tested apparatus. The encoding strip is a magnetic material block having recess and protrusion for identifying encoding information of different positions. The magnetoresistive sensor array is arranged between the encoding strip and the back magnet in a non-contact manner. The back magnet is used for generating a non-uniform magnetic field around the encoding strip so as to magnetize the encoding strip. The magnetoresistive sensor array is used for acquiring the position encoding information of the encoding strip by detecting magnetic field information of the encoding strip. The encoder is low cost and can monitor large distances.Type: ApplicationFiled: February 9, 2021Publication date: December 22, 2022Inventors: Haiping GUO, Weifeng SHEN, Songsheng XUE, Haochen LI

Patent number: 10964528Abstract: Processes for surface treatment of a workpiece are provided. In one example implementation, organic radicals (e.g., methyl CH3 radicals) can be generated by exciting and/or dissociating hydrogen and/or inert gas (e.g., Ar, He, etc) molecules in a remote plasma source and a subsequent reaction with organic molecule (alkanes and alkenes). The organic radicals (e.g., methyl CH3 radicals) can be exposed to the silicon and/or silicon germanium surfaces. After exposure to the organic radicals, the silicon and/or silicon germanium surfaces can be stable in air for a time period (e.g., days) with reduced surface oxidation such that the silicon and/or silicon germanium surfaces can be effectively protected from oxidation. As such, native surface oxide removal process before subsequent process steps can be eliminated.Type: GrantFiled: July 25, 2019Date of Patent: March 30, 2021Assignees: Mattson Technology, Inc., Beijing E-Town Semiconductor Technology Co., Ltd.Inventors: Michael X.
