Patent number: 9193873Abstract: Protein-polymer composite materials are provided according to embodiments of the present invention that include an admixture of a polymer resin, a surfactant and a non-aqueous organic solvent. An aqueous solution containing bioactive proteins is mixed with the admixture. The emulsion is mixed with a crosslinker to produce a curable composition. The curable composition is cured, thereby producing the protein-polymer composite material that is useful for facilitating removal of bioorganic stains.Type: GrantFiled: January 28, 2014Date of Patent: November 24, 2015Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Toyota Motor Corporation, Regents of the University of MinnesotaInventors: Ping Wang, Songtao Wu, Hongfei Jia, Masahiko Ishii, Minjuan Zhang, Xiaodong Tong

Two-terminal memory cell and semiconductor memory device based on different states of stable current
Patent number: 9013918Abstract: A two-terminal memory cell includes a first P-type semiconductor layer, a first N-type semiconductor layer, a second P-type semiconductor layer, and a second N-type semiconductor layer arranged in sequence. A first data state may be stored in the memory cell by applying a forward bias, which is larger than a punch-through voltage VBO, between the first P-type semiconductor layer and the second N-type semiconductor layer. A second data state may be stored in the memory cell by applying a reverse bias, which is approaching to the reverse breakdown region of the memory cell, between the first P-type semiconductor layer and the second N-type semiconductor layer. In this way, the memory cell may be effectively used for data storage.Type: GrantFiled: August 10, 2011Date of Patent: April 21, 2015Assignee: Institute of Microelectronics, Chinese Academy of SciencesInventors: Qingqing Liang, Xiaodong Tong, Huicai Zhong, Huilong Zhu -
