Minnesota discovery could make fuel and plastics production more energy efficient and cost effective
Date:10/12/2011

ave been substantial challenges in processing zeolitic materials into extended sheets that remain intact. To enable energy-savings technology, scientists needed to develop cost-effective, reliable and scalable deposition methods for thin film zeolite formation.

The University of Minnesota team used sound waves in a specialized centrifuge process to develop "carpets" of flaky crystal-type nanosheets that are not only flat, but have just the right amount of thickness. The resulting product can be used to separate molecules as a sieve or as a membrane barrier in both research and industrial applications.

"We think this discovery holds great promise in commercial applications," said Kumar Varoon, a University of Minnesota chemical engineering and materials science Ph.D. candidate and one of the primary authors of the paper published in Science. "This material has good coverage and is very thin. It could significantly reduce production costs in refineries and save energy."
