  • Publication number: 20210296012
    Abstract: A method and apparatus for energy production comprising providing reactive material containing, at least, an exothermic double electron capture capable isotope and supplying pair-formation energy to at least part of the reactive material to form at least one irreversible double electron capture capable nuclei-pair to produce a net exothermic reaction is disclosed. The reactive material may comprise a metallic alloy. A method and apparatus for energy production comprising heating a three or more element metallic alloy in a chemically inert atmosphere to initiate and/or sustain an exothermic reaction between at least two of the metallic elements of the alloy is herein disclosed. The pressure at the surface of the metallic alloy may be maintained below 1000 atm. The reaction may be initiated, maintained or re-initiated by temperature cycling within a target temperature range.

  • Publication number: 20210225531
    Abstract: This disclosure relates to a method and apparatus for energy production from at least one of electron-mediated nuclear reaction and single-element nuclear reaction, wherein a reactive nuclei fuel is loaded into a reactor. The fuel includes one or more reactive nuclei. To maintain a chain reaction, the fuel structure has a multiplication factor of energetic electrons larger than one. A chain reaction is initiated and/or periodically re-initiated in the fuel.

  • Patent number: 10363411
    Abstract: A medical microelectrode includes an elongate electrode body including a tip section, a main body section and, optionally, a coupling section. The tip section, the main body section and, optionally, the coupling section are embedded in a first electrode matrix element, which is substantially rigid, biocompatible and soluble or biodegradable in a body fluid. Additionally the microelectrode includes a dissolution retarding layer on the first electrode matrix element and/or a second electrode matrix element disposed between the first electrode matrix element and the electrode. Upon dissolution or biodegradation of the first electrode matrix element a drug comprised by the first electrode matrix element or the second electrode matrix element is released into the tissue. Also disclosed are bundles and arrays of the electrodes and their use.
