Abstract: Apparatus and methods for facilitating an intramolecular reaction that occurs in single collisions of CO2 molecules (or their derivatives amenable to controllable acceleration, such as CO2+ ions) with a solid surface, such that molecular oxygen (or its relevant analogs, e.g., O2+ and O2− ions) is directly produced are provided. The reaction is driven by kinetic energy and is independent of surface composition and temperature. The methods and apparatus may be used to remove CO2 from Earth's atmosphere, while, in other embodiments, the methods and apparatus may be used to prevent the atmosphere's contamination with CO2 emissions. In yet other embodiments, the methods and apparatus may be used to obtain molecular oxygen in CO2-rich environments, such as to facilitate exploration of extraterrestrial bodies with CO2-rich atmospheres (e.g. Mars).

Abstract: Nanostructured materials, and methods and apparatus for their production are provided. Nanostructured materials comprise nanofibers having nanoparticles deposited along the outer surface thereof. The size of the nanofibers and nanoparticles, and the spacing of such nanoparticles along the nanofibers may be controlled over a wide range. Nanostructured materials may comprise a plurality of such nanofibers interwoven together to form fiber cloth-like materials. Many materials may be used to form the nanofibers including polymer nanofiber materials (e.g., polyvinyl alcohol (PVA) polyvinylpyrrolidone (PVP), etc.) along with compatible nanoparticle materials (e.g., salts or other crystallizable materials).
