    Abstract: An advanced method for processing a solid feedstock such as coal and a liquid feedstock such as bitumen wherein gases produced from such fossil fuel feedstocks are divided in a way as to polygenerate various by-products which includes the conversion of a waste gas (flue gas) containing nitrogen (N2) and carbon dioxide (CO2) generated from the combustion of said gases to produce an intermediate made of carbon (C) and nitrogen (N2) in the form of cyanogen which in turn is converted to a fertilizer such as oxamide. This approach obviates the necessity of CO2 capture and storage in a geologic formation. Besides the making of a fertilizer from a waste gas containing N2 and CO2, the other by-products can be power in the form of electricity and/or steam from a lean gas and liquid transportation fuel like methanol/gasoline, or chemicals from a hydrogen rich gas.

    Abstract: In a method for functionalizing a carbon nanotube surface, the nanotube surface is exposed to at least one vapor including at least one functionalization species that non-covalently bonds to the nanotube surface, providing chemically functional groups at the nanotube surface, producing a functionalized nanotube surface. A functionalized nanotube surface can be exposed to at least one vapor stabilization species that reacts with the functionalization layer to form a stabilization layer that stabilizes the functionalization layer against desorption from the nanotube surface while providing chemically functional groups at the nanotube surface, producing a stabilized nanotube surface. The stabilized nanotube surface can be exposed to at least one material layer precursor species that deposits a material layer on the stabilized nanotube surface.
