Scientist Arthur Ragauskas is helping redefine the bioenergy research frontier

by Kathy Chambers 24 Jul, 2014 in

Dr. Arthur J. RagauskasDr. Arthur J. RagauskasIt is anticipated that the biofuels industry will have a dramatic impact on our lives, much like the petroleum industry. Alternative fuels from renewable cellulosic biomass— plant stalks, trunks, stems, and leaves—are expected to significantly reduce U.S. dependence on imported oil while enhancing national energy security and decreasing the environmental impacts of energy use. Research is currently focused on accelerating the environmental and commercial viability of biofuel production.

The University of Tennessee’s Arthur Ragauskas is one of the notable scientists who are redefining the frontiers of bioenergy research in the quest for an economically feasible and sustainable biofuel industry.

3D printing technology is gaining fresh momentum in Department of Energy (DOE) research endeavors. 3D printing is achieved using an additive manufacturing process that creates 3D objects directly from a computer model, depositing material layer by layer only where required. This technology is expected to exert a profound impact on an increasing array of applications in architecture, engineering, construction, industrial design, automotive, aerospace, military, engineering, dental and medical industries, biotechnology, apparel, eyewear, education, geographic information systems, and many other fields.

Just seven miles south of our OSTI facility in Oak Ridge, Tennessee is a national treasure – the Oak Ridge National Laboratory (ORNL).  ORNL is DOE’s largest multi-program laboratory where remarkable scientific expertise and world-class scientific facilities and equipment are applied to develop scientific and technological solutions that are changing our world. ORNL’s National Center for Computational Sciences is home to two of ORNL’s high-performance computing projects -- the National Climate-Computing Research Center (NCRC), where research is dedicated to climate science, and the Oak Ridge Leadership Computing Facility (OLCF)

  In the world of nanomanufacturing, new materials, devices, components and products are emerging at a breathtaking rate. Next-generation nanocoatings are being developed to enhance wear resistance of industrial materials.  An infrared retina that includes adaptive sensors has been patented. Self-cleaning skin-like prosthetic polymer surfaces have been developed at Oak Ridge National Laboratory (ORNL). ORNL is also well on its way to creating nano catalysts for diesel engine emission remediation
