  • Publication number: 20250095733
    Abstract: A storage device includes a memory cell including a first layer, a second layer, and a memory layer between the first and second layers and can switch between states including a first state and a second state in which electrical resistance is higher, and a circuit executing a write process. The control circuit is configured to, in the process to switch the memory layer from the second to first state, alternately apply to the second layer a first voltage having positive polarity and a second voltage having negative polarity, an absolute value of the second voltage being larger than the first voltage, and in the process to switch the memory layer from the first to second state, alternately apply to the second layer a third voltage having negative polarity and a fourth voltage having positive polarity, an absolute value of the fourth voltage being larger than the third voltage.

  • Publication number: 20200339962
    Abstract: The present invention discloses a Proteus mirabilis phage RDP-SA-16033. The host of the Proteus mirabilis phage is Proteus mirabilis S5. The phage may form a plaque having a diameter of 4-6 mm on a double-layer plate. When observed through an electron microscope, the phage has a head in polyhedral cubic symmetry, is coated by nucleic acid, has a diameter of about 70 nm, has a tail of about 150 nm long, has a tail sheath, has a neck connected to the head and the tail, and belongs to tailed virales myovirus division. The present invention further provides a production process of the phage. After centrifugation of value-added liquid, a titer of the phage is increased by membrane concentration, and then residual host and other infectious microbes in value-added are effectively removed by a ceramic membrane and a 0.22 ?m polyethersulfone filter membrane. Meanwhile, the phage is reserved to the utmost extent.

  • Publication number: 20190083398
    Abstract: The presently disclosed subject matter is directed to an RGD peptide and penetrating peptide R8 co-modified ergosterol and cisplatin active drug-loading liposome that is prepared by means of the incubation of an ergosterol and cisplatin active drug-loading liposome, RGD cyclic peptide, and penetrating peptide R8 in a water bath. The ergosterol and cisplatin active drug-loading liposome is prepared from an ergosterol liposome and a cisplatin solution serving as the raw materials. The ergosterol liposome is prepared from 8 wt % to 15 wt % ergosterol and 85 wt % to 92 wt % liposomes, and the liposomes consist of lecithin and cholesterol.
