  • Patent number: 9193873
    Abstract: 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.

  • Patent number: 9013918
    Abstract: 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.

  • Publication number: 20120281468
    Abstract: The present disclosure provides a semiconductor device and a semiconductor memory device. The semiconductor device can be used as a memory cell, and may comprise 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 semiconductor device 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 semiconductor device by applying a reverse bias, which is approaching to the reverse breakdown region of the semiconductor device, between the first P-type semiconductor layer and the second N-type semiconductor layer. In this way, the semiconductor device may be effectively used for data storage. The semiconductor memory device comprises an array of memory cells consisted of the semiconductor devices.

  • Patent number: 8252571
    Abstract: Processes for preparation of a protein-polymer composite material are provided according to embodiments of the present invention which include providing an admixture of a polymer resin, a surfactant and a non-aqueous organic solvent. An aqueous solution containing bioactive proteins and substantially free of surfactant 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.

  • Publication number: 20100093052
    Abstract: Systems and methods are provided separating a first group of cells from a mixture of at least first and second groups of cells in a suspending fluid. The system includes an annular flow channel and at least one magnetic element positioned around the exterior of the annular flow channel as to provide a radially symmetric magnetic field around at least a portion of the annular flow channel. The at least one magnetic element is configured to provide a gradually increasing magnetic field along the axis of flow as to limit the maximum magnetic gradient within the annular flow channel. A pump is operatively connected to a terminal end of the annular flow channel to force the suspending fluid through the annular channel.
