  • Patent number: 11670726
    Abstract: A method of generating electricity from light, that uses a photovoltaic array, that includes a junction between an inorganic electron-donating layer and an inorganic electron-accepting layer. The electron-donating layer includes moieties which after photon activation have unpaired electrons, and wherein some of the electrons are freed when light strikes the electron-donating layer, thereby transforming the moieties into free radicals or equivalents but many of the freed electrons recombine. Also, many of the free radicals or equivalents in the triplet state are optimally responsive to a selective magnetic field that has been determined to optimally increase the lifetime of the triplet state of the free radicals and thereby forestall recombination of the freed electrons into the free radicals. A magnetic field of substantially the optimal strength that is substantially unvarying over the electron donating layer is created as the array is being exposed to light.

  • Publication number: 20210145981
    Abstract: A method of killing cells of a targeted cell type in a patient body that utilizes nanoparticles having a first portion, which when exposed to a target portion of a targeted cell type, binds to the target portion and a second portion, joined to the first portion, and comprised of a low resistivity material. The nanoparticles are introduced into a contact area where they contact cells of the targeted cell type. Contemporaneously, the contact area is exposed to a varying magnetic field of insufficient strength to increase the temperature of any part of the patient body by more than ten degrees Celsius, but which creates a current at the nanoparticles sufficient to disrupt function of the targeted cell type.

  • Patent number: 9789328
    Abstract: In the treatment of a tumor with radiation therapy is enhanced by a weak magnetic field, the field strength time sequence of exposure and shape and contour of the magnetic field are varied to achieve desired results. In one separate aspect, exposure to a magnetic field is continued after exposure to a free radical-creating therapy is ceased or diminished, thereby increasing the lifetimes of free radicals which have already been created. In another preferred embodiment a magnetic field is strategically placed to avoid extending the lives of free radicals in tissue through which a free radical-creating beam must pass, to reach a tumor. This application discloses quantitative parameters for field strength and exposure time to create concentrations and reactivity of free radicals, including long-lived free radicals and discloses the use of shaped, contoured, and designed electromagnetic fields. A treatment planning station is also disclosed.

  • Patent number: 8448673
    Abstract: A method and system for transporting fluid is described. The method includes coupling a transit vessel to a terminal vessel associated with at least one terminal. The transit vessel and the terminal vessel are coupled at an open sea or lightering location, which may be selected based upon operational conditions. Then, cryogenic fluid is transferred between the transit vessel and the terminal vessel, while the transit vessel and terminal vessel are moving in substantially the same direction. Once the transfer is complete, the terminal vessel decouples from the transit vessel and moves a terminal to provide the cryogenic fluid to the terminal. The cryogenic fluid may include liquefied natural gas (LNG) and/or liquefied carbon dioxide (CO2).
