Professor Daniel Resasco holds the Douglas Bourne Chair of the School of Chemical, Biological and Materials Engineering at the University of Oklahoma. He is also George Lynn Cross Professor, the highest research honor bestowed by the University. He received his B.S. in Chemical Engineering at the Universidad Nacional del Sur, Argentina (1975) and his Ph.D. from Yale University (1984). He has received the 2004 Oklahoma Chemist of the Year from the American Chemical Society, the Yale Award for Advancement of Basic and Applied Science from the Yale Science and Engineering Association, Yale University, the Regents Award for Superior Research, University of Oklahoma (1999), the Sam A. Wilson Professorship, and the J. and K. Smalley Presidential Professorship (1996). He received the Big XII Rising Star Award from the Big XII Center for Economic Development, Innovation, and Commercialization and was finalist for the Small Times US Innovator of the Year in 2007. In 1987 he received the B. Houssay Award for Scientific Achievement from the National Research Council of Argentina. He has also served as a Chairman in the Chemical Engineering Department at the Universidad Nacional de Mar del Plata (1987-88). From 1991 to 1993 he was appointed Senior Scientist at Sun Company, Inc., Pennsylvania. He has been member of the Executive Committee of the International Congress on Catalysis (1996) and Associate Editor of the Journal of Catalysis, for which he is now a member of the Editorial Board. He is founder of SouthWest Nanotechnologies Inc., a major producer of high quality single-walled carbon nanotubes.
The Nanotube Research group at the University of Oklahoma has an interdisciplinary team with a wide experience in catalytic science as well as engineering and chemistry. For more information about our researchers and students use the following links:
The role of water in carbon feed on the surface-guided growth of horizontally aligned single-walled carbon
nanotubes (HA-SWCNTs) was investigated. It is shown that the amount of water can be optimized to favor HA-SWCNT growth, which is proposed to be due to selective etching of carbon deposits at carbon–metal interface. Without water, nanotube–nanotube interaction and carbon accumulation at the interface are disproportionately large compared to the rate of nanotube growth, leading to catalyst deactivation. With excess water, suppression of nanotube growth occurs, resulting in reduced carbon yield on the surface.
Intermediate carbon/water feed ratios achieve cleaner growth with high efficiency.
