Nanoparticles and systems and methods for synthesizing nanoparticles through thermal shock
Systems and methods of synthesizing nanoparticles on substrates using rapid, high temperature thermal shock. A method involves depositing micro-sized particles or salt precursors on a substrate, and applying a rapid, high temperature thermal shock to the micro-sized particles or the salt precursors to become nanoparticles on the substrate. A system may include a rotatable member that receives a roll of a substrate sheet having micro-sized particles or salt precursors; a motor that rotates the rotatable member so as to unroll the substrate; and a thermal energy source that applies a short, high temperature thermal shock to the substrate. The nanoparticles may be metallic, ceramic, inorganic, semiconductor, or compound nanoparticles. The substrate may be a carbon-based substrate, a conducting substrate, or a non-conducting substrate. The high temperature thermal shock process may be enabled by electrical Joule heating, microwave heating, thermal radiative heating, plasma heating, or laser heating.

Desulfurization and Sulfur Tolerant Hydrogenation Processes of Hydrocarbon Feedstocks
The present invention is a method for removing sulfur from liquid hydrocarbon feedstocks and for performing hydrogenation reactions in sulfur-contaminated feedstocks, including the hydrogenation of naphthalene in the presence of sulfur compounds, using catalysts or adsorbents comprising metal oxide nanowires decorated with reduced catalytically-active metal particles. In a preferred embodiment, the adsorbent comprises zinc oxide nanowires decorated with catalytically-active metals selected from nickel, cobalt, molybdenum, platinum, palladium, copper, oxides thereof, alloys thereof, and combinations thereof. In some embodiments, the sulfur is removed through a desulfurization process without an external hydrogen supply. The process is effective for the removal of sulfur from diesel fuels and liquid fuel streams, and for deep desulfurization of natural gas streams. The process is also effective for the selective hydrogenation of naphthalene to tetralin in the presence of sulfur compounds.
