Patent number: 10786530Abstract: Antimicrobial cationic polymers having one or two cationic polycarbonate chains were prepared by organocatalyzed ring opening polymerization. One antimicrobial cationic polymer has a polymer chain consisting essentially of cationic carbonate repeat units linked to one or two end groups. The end groups can comprise a covalently bound form of biologically active compound such as cholesterol. Other antimicrobial cationic polymers have a random copolycarbonate chain comprising a minor mole fraction of hydrophobic repeat units bearing a covalently bound form of a vitamin E and/or vitamin D2. The cationic polymers exhibit high activity and selectivity against Gram-negative and Gram-positive microbes and fungi.Type: GrantFiled: April 17, 2018Date of Patent: September 29, 2020Assignees: International Business Machines Corporation, Agency For Science, Technology And ResearchInventors: Daniel J. Coady, Richard A. Dipietro, Amanda C. Engler, James L. Hedrick, Ashlynn L. Z. Lee, Victor W. L. Ng, Zhan-Yuin Ong, Yi Yan Yang

Patent number: 9660573Abstract: A solar panel enclosure converts sunlight to electricity. To remove the large amount of heat from the enclosure a chambered heat exchanger (CHE) is thermally coupled thereto. An air temperature differential is created between chamber air in a CHE portion and chamber air within a CHE heat exchanging portion. When a threshold thermal gradient is reached, air pressure that keeps the chamber air static is overcome creating airflow within the chamber. The airflow draws cooler ambient air from a chamber inlet. Heat from the enclosure is transferred to the cool air and is exhausted from a chamber outlet.Type: GrantFiled: January 5, 2015Date of Patent: May 23, 2017Assignee: GLOBALFOUNDRIES INC.Inventors: Richard A. DiPietro, Thomas J. Fleischman, Richard Hutzler, Keith B. Maddern, Mitchell Montanez, William K. Morse

Patent number: 9656000Abstract: A wound dressing and a method of making the wound dressing is described herein. The wound dressing is formed of an absorbent substrate formed of one or more layers and a low-adherence layer disposed on the substrate. The low-adherence layer can be disposed within at least a portion of the substrate. The low-adherence layer is formed of a mixture of at least one highly fluorinated polymer and at least one acidic polymer. The at least one highly fluorinated polymer has a fluorine content greater than the fluorine content of the at least one acidic polymer.Type: GrantFiled: October 18, 2012Date of Patent: May 23, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Robert D.
