Nanofibers clean sulfur from fuel - Sulfur compounds in petroleum fuels have met their nano-structured match. University of Illinois researchers developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels much more effectively than traditional materials. Sulfur has to be removed because it emits toxic gasses and corrodes catalysts. Such efficiency could lower costs and improve performance for fuel-based catalysis, advanced energy applications and toxic gas removal.(10.1038/nnano.2012.194)
