Abstract: The present disclosure relates to devices for generating electrical energy, methods for generating electrical energy, products for use in devices for generating electrical energy and methods for producing devices for generating electrical energy. In certain embodiments, the present disclosure provides an electrical energy generating device, the device comprising at least one cell comprising: first and second spaced electrodes, the first electrode comprising a low work function material and the second electrode comprising a high work function material; and disposed between the first and second electrodes, beta particle emitting radionuclides and a semiconducting material, the semiconducting material capable of producing electron hole pairs in response to beta particle emission from the radionuclides.

Abstract: The present disclosure relates to methods, systems and products for converting carbon dioxide to one or more small organic compounds. In certain embodiments, the present disclosure provides a method of converting CO2 and/or a related form thereof to one or more small organic compounds, the method comprising exposing the CO2 and/or the related form thereof to a beta particle activated high band-gap semiconductor and thereby converting the CO2 and/or the related form thereof to the one or more small organic compounds.
