Patent number: 10881760Abstract: A cryogel which includes lignin nanoparticles embedded in crosslinked gelatin. The cryogel is formed at subfreezing temperatures where aggregation of polymerized or crosslinked materials is prevented by ice crystals. When thawed, the cryogel is a densely crosslinked microporous composition with a plurality of pores ranging from 50-150 ?m in size. The cryogel combines a natural bio waste polymer in the form of lignin together with a collagen derived natural polymer. Incorporation of lignin within gelatin improves the mechanical performance of the cryogel and enhances its shape recovery rate. The macropororous composition inhibits growth of both gram positive and gram negative bacteria. In addition, the macoporous composition exhibits excellent free radical scavenging activity. All of the properties make the cryogel an excellent material for wound healing and tissue engineering applications.Type: GrantFiled: August 10, 2020Date of Patent: January 5, 2021Assignee: KING ABDULAZIZ UNIVERSITYInventors: Adnan Memic, Tuerdimaimaiti Abudula

Publication number: 20200243741Abstract: A thermoelectric module comprising nanostructured SnO and SnO2, and electrodes arranged between two electrical insulating substrates is described. The nanostructured SnO may be in the form of nanosheets and acting as p-type pillars of the module. The nanostructured SnO2 may be in the form of nanospheres and acting as n-type pillars of the module. This thermoelectric module is evaluated on the voltage, current, and power of the electricity generated once subjected to a temperature gradient.Type: ApplicationFiled: January 25, 2019Publication date: July 30, 2020Applicant: King Abdulaziz UniversityInventors: Numan SALAH, Ahmed ALSHAHRIE, Neazar BAGHDADI, Waleed M.

Patent number: 10669514Abstract: Inserts for the wells of tissue culture plates are provided. When placed in a tissue culture well, a bottom surface of a shaft portion of an insert contacts a bottom surface of the well and blocks the growth of cells in that area. The blocked area mimics a “wound” in the layer of cells that grows around it. A cover portion of the insert comprises open channels through which cells, media, etc. can be delivered and gases exchanged while the insert is in place. Once the insert is removed, cell culture with the artificial “wound” is used to test the efficacy of agents with respect to their ability to facilitate cell growth into and closure of the “wound”.Type: GrantFiled: November 20, 2019Date of Patent: June 2, 2020Assignee: King Abdulaziz UniversityInventors: Adnan Memic, Tuerdimaimaiti Abudula, Kalamegam Gauthaman

Patent number: 9862883Abstract: A method of making doped Alq3 nanostructures with enhanced photoluminescence is provided. The method of making doped Alq3 nanostructures with enhanced photoluminescence includes the steps of dissolving tris(8-hydroxyquinolinato)aluminum (Alq3) and a metal in water to form a solution. The metal may be terbium (Tb), copper (Cu), silver (Ag), dysprosium (Dy) or europium (Eu), for example. The metal may be provided in a water soluble form, such as chlorides and nitrates thereof. The solution is then subjected to ultrasonic waves (i.e., a sonication bath) for a period of approximately 3 hours to approximately 4 hours. The solution is then dried at a temperature of approximately 50° C. for a period of approximately 8 hours to form a powder of Alq3 doped with the metal. The powder is then formed into nanostructures of the Alq3 doped with the metal.Type: GrantFiled: June 22, 2015Date of Patent: January 9, 2018Assignee: KING ABDULAZIZ UNIVERSITYInventors: Numan Abdullah Salah, Adnan Memic, Attieh A.
