  • Aqueous polysulfide-based electrochemical cell
    Patent number: 11973254
    Abstract: An electrochemical cell and battery system including cells, each cell including a catholyte, an anolyte, and a separator disposed between the catholyte and anolyte and that is permeable to the at least one ionic species (for example, a metal cation or the hydroxide ion). The catholyte solution includes a ferricyanide, permanganate, manganate, sulfur, and/or polysulfide compound, and the anolyte includes a sulfide and/or polysulfide compound. These electrochemical couples may be embodied in various physical architectures, including static (non-flowing) architectures or in flow battery (flowing) architectures.

  • LAYERED LUMINESCENT SOLAR CONCENTRATORS
    Publication number: 20210193857
    Abstract: The present disclosure features a luminescent solar concentrator, including a layer including a quantum-cutting material; and a layer including a broadly light-absorbing material (that is also photoluminescent) optically coupled to and beneath the layer including the quantum-cutting material, relative to a light source.

  • Low cost high efficiency steam heating system
    Patent number: 5056714
    Abstract: A low cost-high efficiency steam heating system is disclosed. A pressure sensing switch in the radiation device triggers a timer when a predetermined pressure is achieved in the radiator. The timer is interposed between a thermostat and boiler-burner assembly so as to deactivate the boiler-burner for predetermined periods until the set point of the thermostat is reached.

  • Method of synthesizing brevicomin and using same in beetle control
    Patent number: 4695584
    Abstract: A method of producing synthetic brevicomin by direct distillation and a method of using the same in interfering with normal propagation of Dendroctonus beetles.
    Type: Grant
    Filed: January 24, 1983
    Date of Patent: September 22, 1987
    Assignee: University of Pittsburgh
    Inventors: Theodore Cohen, James Matz
  • Method for brevicomin synthesis and use in beetle control
    Patent number: 4609743
    Abstract: A process for the production of the beetle aggregation pheromone brevicomin comprising reacting acrolein dimer sequentially with ethyllithium, a methylating agent and aqueous protonic acid. In a modification of the process the acrolein dimer is reacted with ethyl Grignard reagent prior to reaction with an alkyllithium compound. The process includes distributing the brevicomin product to areas to be controlled for beetles.
