  • Alternating magnetic field systems and methods for generating nanobubbles
    Patent number: 11939245
    Abstract: Alternating magnetic field (AMF) systems and devices and methods for producing nanobubbles said methods and devices. The AMF systems and devices of the present invention may feature sets of magnets configured to expose a flowing liquid to an alternating magnetic field. The alternating magnetic field destabilizes dissolved gas molecules to produce nanobubbles. The methods, systems, and devices of the present invention may be used to treat solution, for reducing fouling or corrosion in a tube system or pipe system, methods for increasing water porosity of soil, methods for treating thromboembolic disease, etc.
    Type: Grant

  • Method of increasing the band gap of iron pyrite by alloying with oxygen
    Patent number: 9450120
    Abstract: A method of increasing the band gap of iron pyrite by alloying with oxygen is disclosed. According to one embodiment, a method comprises alloying iron pyrite (FeS2) with oxygen to form an iron pyrite and oxygen alloy (FeS2?xOx). The iron pyrite and oxygen alloy (FeS2?xOx) has a band gap greater than iron pyrite (FeS2).
