More flexible method floated to produce biofuels, electricity--Purdue News (10/14/08)

WEST LAFAYETTE, Ind. - Researchers are proposing a new "flexible" approach to producing alternative fuels, hydrogen and electricity from municipal solid wastes, agricultural wastes, forest residues and sewage sludge that could supply up to 20 percent of transportation fuels in the United States annually.
The method offers a potential solution to problems that might be created by increasing production of ethanol with conventional methods, which use corn grain as a feedstock. Boosting ethanol production with conventional methods would require additional crops and heavy fertilizer use, increasing runoff into waterways and threatening ecosystems.
The new concept, however, which Purdue researchers call a flexible carbon-to-liquid fuel process, would require no additional crops and use primarily wastes as the feedstock, said Fu Zhao, a Purdue assistant professor of mechanical engineering.

WEST LAFAYETTE, Ind. - The U.S. Department of Energy has awarded a grant to a Purdue University professor in the College of Engineering working on the characteristics of metals. Xinghang Zhang, a professor in the School of Materials Engineering, received a $450,000 grant from the federal Office of Basic Energy Sciences as the primary investigator for a three-year research project, "Deformation Mechanisms of Nanotwinned Aluminum and Binary Aluminum alloys." "This allows us to explore fundamental science on mechanical behavior of nanotwinned aluminum and could eventually lead to the design of high strength and ductile aluminum alloys," he said. Nanotwinned metals can be used in many applications because they simultaneously demonstrate high strength and high ductility, characteristics usually thought to be mutually exclusive. Deformation mechanisms describe how a metallic material can change its geometry under external force. The research will be done at the microscopic level by using a transmission electron microscope that can reveal the atomic arrangement inside aluminum. The School of Materials Engineering recently acquired an advanced transmission electron microscope for the deformation project and future research.Read Full Story
