  • Patent number: 10786530
    Abstract: 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.

  • Patent number: 9660573
    Abstract: 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.

  • Patent number: 9656000
    Abstract: 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.
