Patent number: 11957057Abstract: A CaTiO3-based oxide thermoelectric material and a preparation method thereof are disclosed. The CaTiO3-based oxide thermoelectric material has a chemical formula of Ca1-xLaxTiO3, where 0<x?0.4. The present disclosure makes it possible to prepare a CaTiO3-based thermoelectric material with properties comparable to n-type ZnO, CaTiO3, SrTiO3 and other oxide thermoelectric materials. Among them, the La15 sample has a power factor reaching up to 8.2 ?Wcm?1K?2 (at about 1000 K), and a power factor reaching up to 9.2 ?Wcm?1K?2 at room temperature (about 300 K); and a conductivity reaching up to 2015 Scm?1 (at 300 K). The CaTiO3-based oxide thermoelectric material exhibits the best thermoelectric performance among calcium titanate ceramics. The method for preparing the CaTiO3-based oxide thermoelectric material of the present disclosure is simple in process, convenient in operation, low in cost, and makes it possible to prepare a CaTiO3-based ceramic sheet with high thermoelectric performance.Type: GrantFiled: July 14, 2020Date of Patent: April 9, 2024Assignee: Dalian University of TechnologyInventors: Huijun Kang, Tongmin Wang, Jianbo Li, Zhiqiang Cao, Zongning Chen, Enyu Guo, Yiping Lu, Jinchuan Jie, Yubo Zhang, Tingju Li

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
