    Abstract: Processes of producing nanoparticles from solid phase precursor non-nanoparticles. Contacting a solid phase precursor non-nanoparticle selected from oxides of metals and metalloids, carbides of metals and metalloids, nitrides of metals and metalloids, borides of metals and metalloids, silicides of metals and metalloids, and phosphides of metals and metalloids, and mixtures thereof, with one or more onium ions in water in a vessel. Some processes can be one pot processes. The vessel is agitated and held at temperature for a time sufficient to form nanoparticles with the same crystalline structure as the solid phase precursor non-nanoparticle as determined by XRD and/or TEM. Nanoparticles made by the processes. Processes of use of the nanoparticles.

    Abstract: By combining two-dimensional (2D) transition metal oxide and/or carbo-oxides with sulfur, one can form cathodes for use in Li—S batteries, which batteries in turn exhibit high capacity and other attractive characteristics. Accordingly, provided herein are methods, comprising: forming an admixture that comprises sulfur, a 2D transition metal carbo-oxide, and optionally a conductive material. Also provided are electrodes, comprising sulfur, a 2D transition metal carbo-oxide, and optionally a conductive material. Further provided are energy cells, the energy cell comprising a first electrode according to the present disclosure. Additionally provided are methods, the methods comprising discharging an energy cell according to the present disclosure or charging an energy cell according to the present disclosure. Also provided are electrical devices, comprising an energy cell according to the present disclosure.

    Abstract: A method, comprising: to an initial sample that has an initial concentration of urea in solution, contacting a composition comprising metal oxide nanofilaments under such conditions that at least some of the urea adsorbs to the metal oxide nanofilaments so as to give rise to a final concentration of urea in the solution A device for removing urea from an initial aqueous solution of urea, the device comprising an exchangeable cartridge of metal oxide nanofilaments composition through which the initial aqueous solution is directed to pass, the passage adapted to allow the initial aqueous urea solution to contact the metal oxide nanofilaments contained in the cartridge. Contacting a composition comprising metal oxide-based nanofilaments to an initial sample that comprises a metal ion and/or a metal under such conditions that at least some of the metal ion and/or the metal associates with the metal oxide nanofilaments.
