Membrane Science, Engineering and Technology Center (MAST) The Membrane Science, Engineering and Technology (MAST) Center advances membrane technology in separation processes through research and development, promotes education in membrane science and engineering, and provides effective technology transfer between the center and its industrial sponsors. Headquartered at CU for more than 20 years, fundamental and applied center research has led to major advancements in membrane materials and membrane separation processes in established as well as emerging areas including energy production, water treatment, pharmaceutical purification, and chemical processing that will ultimately benefit the environment and public health. As one of NSF’s longest-running Industry/University Cooperative Research Centers (I/UCRC), the MAST Center is well along in its current phase as a multi-university center, with New Jersey Institute of Technology serving as the lead site. Center researchers from CU and NJIT also collaborate with researchers from several other schools including Colorado State University, University of Arkansas, Clemson University, and Ben Gurion University. The center has succeeded in drawing researchers from diverse fields including biological, chemical, physical, and materials sciences; health and pharmaceutical sciences; and aeronautical, chemical, civil, environmental, mechanical, electrical and computer engineering.

MAST Center Directors: Alan Greenberg and Richard Noble Professor Alan Greenberg received his PhD in biomedical engineering from Drexel University. He is a fellow of the American Association for the Advancement of Science and recently served as a technical expert for the Singapore Environment and Water Industry Development Council. His 30 years of research experience at CU includes the formation, characterization, and performance of membranes, mechanical properties of materials in bulk and thin-film form, and physical and mechanical behavior of biological materials. Greenberg’s research has pioneered innovative real-time techniques for nondestructive measurement of material performance, including the use of ultrasound for monitoring membrane fouling, compaction and morphology. In addition, his work has successfully utilized an integrated modeling and experimental approach that has led to first-principles models that describe important membrane formation processes.

Professor Richard Noble is the Alfred T. and Betty E. Look Professor of Chemical Engineering at the University of Colorado Boulder. He has more than 20 years of experience in the modeling and analysis of membrane and other thin film systems that include diffusive transport and chemical reaction. Noble is the country’s leading researcher in the modeling and experimental implementation of facilitated transport membranes. His expertise includes the modeling and use of pH, electrical and photon fields to obtain solute separation and concentration. Professor Noble is an internationally recognized leader in the use of novel membrane and thin film materials, including zeolites and ionic liquids, for chemical separations. He holds more than 20 patents and has authored more than 260 research publications, including 11 textbooks and monographs.

Recent Highlights MAST Center faculty Scott Bunch and John Pellegrino, along with CU graduate students, have produced the first experimental results showing that atomically thin graphene membranes with tiny pores can effectively and efficiently separate gas molecules through sizeselective sieving. The findings are a major step toward more energy-efficient membranes for natural gas production and reducing carbon dioxide emissions from power plant effluent.

u Wei Zhang and Rich Noble were awarded a two-year NSF I/UCRC Fundamental Research Supplemental Opportunity award, entitled “Efficient Molecular Separation Using Polymeric Membranes Integrated with Novel Structure-Tunable Organic Nanocages.” This research allows extension of the synthesis of a new type of organic cage structure to new applications. This novel material platform has potential for a number of important chemical separation issues, including carbon dioxide separation and olefin/paraffin separation.

ION Engineering, LLC is a new CU spin-off company commercializing ionic liquid separation processes developed by Richard Noble and Douglas Gin. It was awarded a three-year, $4M research grant from DOE to conduct benchscale testing of an amine-based solvent that employs an ionic liquid instead of water as the physical solvent, greatly reducing regeneration energy while lowering process water usage.

u Alan Greenberg, with colleagues from Ben Gurion University in Israel and Hashemite University in Jordan, secured a three-year award from the NATO Science for Peace Program and a one-year award from the Middle East Desalination Research Center. Their work utilizes sensor technology developed in the MAST Center for a new desalination process to produce potable water from inland brackish water sources. The technology is currently being tested on pilot-scale facilities with expectations for subsequent commercialization.
