Patent number: 11414455Abstract: Disclosed are monoacylated Toll-like receptor 2 ligands which can be used in both the development of targeted agents for the imaging and treatment of pancreatic cancer as well as other cancers, and as an adjuvant for cancer immunotherapy. The monoacylated compounds disclosed herein have a higher binding affinity for TLR2 relative to a known potent diacylated agonists, but only ?½ the bioactivity. Competition of the monoacylated compound with the diacylated compound for binding TLR2 was confirmed. Hence, the reported monoacylated compounds are inhibitors/antagonists of TLR2 activation.Type: GrantFiled: October 5, 2020Date of Patent: August 16, 2022Assignees: H.

Patent number: 11402752Abstract: A method of fabricating an optical connection to at least one planar optical waveguide integrated on a planar integrated circuit (PIC) uses a machine vision system or the like to detect one or more positions at which one or more optical connections are to be made to at least one planar optical waveguide located on the PIC. A spatial light modulator (SLM) is used as a programmable photolithographic mask through which the optical connections are written in a volume of photosensitive material using a photolithographic process. The SLM is programmed to expose the photosensitive material to an illumination pattern that defines the optical connections. The programming is based at least in part on the positions that have been detected by the vision system. The optical connections are printed by exposing the photosensitive material to illumination that is modulated by the pattern with which the SLM is programmed.Type: GrantFiled: October 3, 2016Date of Patent: August 2, 2022Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Thomas L.

Patent number: 11391896Abstract: In accordance with a method for transferring optical signals to and from an optical component incorporated in a photonic integrated circuit (PIC), an incoming optical signal in a first polarization state is received at a splitter section of a polarization splitter rotator (PSR). The splitter section causes the optical signal to be directed to a first waveguide of a pair of waveguides of the PSR. One of the waveguides rotates a polarization state of an optical signal traversing therethrough into an orthogonal polarization state and the other waveguide maintains a polarization state of an optical signal traversing therethrough. The incoming optical signal is directed from the first waveguide to the optical component. An outgoing optical signal is received in a second waveguide of the pair such that the outgoing optical signal traverses the second waveguide and the splitter section to be output by the PSR.Type: GrantFiled: May 16, 2019Date of Patent: July 19, 2022Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventor: Erfan M.

System, apparatus, and process for leaching metal and storing thermal energy during metal extraction
Patent number: 11390933Abstract: An environmentally friendly (e.g. no acid, base, or cyanide) system and process for large scale extraction of metal ion into aerobic molten salt (or ionic liquid) and the electrodeposition of metal (e.g. copper, gold, silver, etc.) from the metal ion dissolved in the molten salt. The non-volatile low vapor pressure liquid salt is reusable, and heat from the molten slag can heat the molten salts or ionic liquids. Another embodiment comprises a one-pot apparatus for the extraction of metal (e.g. copper) from metal earths and electrodepositing the metal using a low melting (209° C.) aerated Na—K—Zn chloride salt in which copper metal oxidizes and is converted to soluble copper chloride. When an electrical power supply is connected to the graphite vessel (cathode) and to copper rods in the melt (anodes), then the copper chloride is deposited as copper metal by electroreduction on the bottom of the graphite reaction vessel.Type: GrantFiled: September 16, 2020Date of Patent: July 19, 2022Assignees: CLEAN RESOURCES PTE.
