  • Patent number: 11875908
    Abstract: An electrode for beta-photovoltaic cells includes: a substrate formed of a conductive layer with a thickness ranging between about 10 nm to 1 micron; a composite layer of radioluminescent phosphor with radioisotope particles homogeneously dispersed therein formed on conductive substrate with a thickness ranging between about 1 and 25 microns; and a semiconductor comprising a P-i-N/P-u-N junction or a N-i-P-P junction. The radioisotope may be a beta-emitter, such as Ni-63, H-3, Pm-147, or Sr-90/Y-90.
    Type: Grant
    Filed: June 30, 2021
    Date of Patent: January 16, 2024

  • Patent number: 11081252
    Abstract: An electrophoretic deposition (EPD) process forms a radioluminescent phosphor and radioisotope composite layer on a conductive surface of a substrate. In the composite layer formed, the particles of radioisotope are homogeneously dispersed with the radioluminescent phosphor. The radioisotope may be a beta-emitter, such as Ni-63, H-3, Pm-147, or Sr-90/Y-90. By applying the composite layer using the EPD process, the electrode can be configured for betavoltaic, beta-photovoltaic and photovoltaic cells according to further embodiments. A direct bandgap semiconductor device can convert betas and/or photons emitted from composite layer. Methods and choice of materials and components produces a hybrid radioisotope battery, conversion of photons and nuclear decay products, or radioluminescent surfaces.

  • Patent number: 6996951
    Abstract: A flexible container is provided for the storage and administration of medical solutions. The container incorporates a transparent front sheet made from a planar layer of a polymer and an opposing rear sheet. The rear sheet is made from a planar laminate layer. The front and rear sheets are sealed together along a common peripheral edge to form a volume enclosure. The volume enclosure is constructed of materials having high oxygen and moisture barrier properties which allows the container thermoplastic to be stored for extended periods of time without degrading the contents. The volume enclosure is then inflated with a pressurized gas to permanently stretch the front and rear sheets outwardly and to thereby increase the volume capacity of the container. An alternative embodiment of the container incorporates multiple compartments, separated by peelable seals, for containing a diluent and a medicament.
