    Abstract: A first process and sorbent for removing ammonia from a gaseous environment, the sorbent comprised of graphene oxide having supported thereon at least one compound selected from metal salts, metal oxides and acids, each of which is capable of adsorbing ammonia. A second process and sorbent system for removing ammonia and a volatile organic compound from a gaseous environment; the sorbent system comprised of two graphene-based materials: (a) the aforementioned graphene oxide, and (b) a nitrogen and oxygen-functionalized graphene. The sorbents are regenerable under a pressure gradient with little or no application of heat. The processes are operable through multiple adsorption-desorption cycles and are applicable to purifying and revitalizing air contaminated with ammonia and organic compounds as may be found in spacesuits, aerospace cabins, underwater vehicles, and other confined-entry environments.

    Abstract: An individual solid oxide cell (SOC) constructed of a sandwich configuration including in the following order: an oxygen electrode, a solid oxide electrolyte, a fuel electrode, a fuel manifold, and at least one layer of mesh. In one embodiment, the mesh supports a reforming catalyst resulting in a solid oxide fuel cell (SOFC) having a reformer embedded therein. The reformer-modified SOFC functions internally to steam reform or partially oxidize a gaseous hydrocarbon, e.g. methane, to a gaseous reformate of hydrogen and carbon monoxide, which is converted in the SOC to water, carbon dioxide, or a mixture thereof, and an electrical current. In another embodiment, an electrical insulator is disposed between the fuel manifold and the mesh resulting in a solid oxide electrolysis cell (SOEC), which functions to electrolyze water and/or carbon dioxide.

    Abstract: A portable, compact, real-time and accurate sensor and method for deriving a physicochemical property of a liquid fuel, such as cetane number, carbon content, carbon/hydrogen (C/H) atomic ratio, or heating value (net heat of combustion). The sensor comprises a constant-volume ignition chamber equipped for measuring ignition delay and magnitude of a peak rise in pressure or temperature following dispensation of a liquid fuel into the chamber. The sensor utilizes air at atmospheric pressure and microliter quantities of fuel. The sensor can be implemented in real-time refinery operations for blending diesel fuels that meet government mandated cetane number standards as well as in applications for standardizing jet, biodiesel, and synthetic fuels, which presently are not classified by any physicochemical property.
