  • Patent number: 11411281
    Abstract: A multi-layer composite functional separator for lithium ion battery includes four layers. Layer A is a base separator. Layer B is a porous structural layer composed of insulating inorganic compounds or high temperature resistant polymers. Layer C is a porous layer composed of polymer microspheres with temperature-induced expansion characteristics. Layer D is a thermoplastic resin with a melting point of 80-110° C. and a crystallinity of <50%. Layer B, Layer C and Layer D are sequentially attached on either or both sides of Layer A. Compared with the existing lithium-ion battery separator, the multi-Layer Composite functional separator has excellent heat resistance. The thermal shrinkage rate is less than 1% when heated for less than one hour at 200° C. Inclusion of organic polymer microspheres produces thermal closure of the batteries, which improves the safety of the batteries.

  • Patent number: 10117871
    Abstract: Various embodiments described herein are directed to compounds of formula (I), (II), (III) or (IV) for use as potent inhibitors of HIV integrase and for treatment of patients afflicted with AIDS. A major challenge of human immunodeficiency virus (HIV) chemotherapy continues to be the inevitable selection of resistance by the virus towards known drug regimens. Treating resistant HIV strains calls for novel antivirals with unique structural cores. Some embodiments are directed to compounds featuring a 3-hydroxypyrimidine-2,4-dione-5-carboxamide core that consistently confers low nanomolar potencies against HIV-1 in cell culture. Biochemical testing and molecular modeling results corroborate an antiviral mechanism of action of inhibiting integrase strand transfer (INST). Preliminary testing against raltegravir-resistant HIVs showed marginal cross resistance, suggesting that the chemotypes of the various embodiments described herein could fit an inhibitory profile of second generation INSTIs.
