The goals of the University Cooperative Research Center are to perform industrially relevant research to address the technology needs of surfactant-polymer systems. These environmentally benign surfactants are to be developed as more efficient surface-active reagents with specific applications for the industry.
Columbia University, New York City, NY
The center was established in 1998. Detailed structure-property assessment of several classes of surface-active molecules is a major activity of the center. The focus is on design, development and characterization of solution and interfacial behavior of specialty surfactants. The aim is to develop and characterize these novel surfactants for industrial applications.
Since the inception of the center, numerous publications have been generated. Technology transfer is one of the most important products. There is a Web site for this project (http://www.columbia.edu/cu/iucrc).
The development and characterization of new surfactants will enhance the petroleum industry’s ability to economically recover oil remaining in mature fields using enhanced oil recovery (EOR) applications. This will help to increase the volume of oil produced from domestic reservoirs and reduce the level of imports required to meet the energy demands of a growing economy.
The study requires simultaneous investigation of the interaction of individual components in bulk solution as well as the interface that is in contact with it and will use a multi-pronged approach involving:
DOE is no longer a member of the consortium due to budget priorities. This cutting-edge research includes synthesizing nano-structures of aggregates of mixed surfactants in solutions and at solid/liquid interfaces. Funding to continue as a consortium member has not been identified.
The project was awarded via purchase order for 2006. As of July 2007, no funding is available for 2007 membership.
