Angewandte author profile

Professor Tsapatsis's research group is housed in the department of Chemical Engineering & Materials Science at the University of Minnesota in the Twin Cities. The focus of our work is in demonstrating innovative processing strategies for engineering functional devices and microstructures. Our recent publications focus on molecular sieve synthesis, crystal structure elucidation, pattern formation, morphology control, and incorporation in engineering devices. Our work is strengthened by substantial industrial interactions. Take a closer look at our research.

Professor Michael Tsapatsis receives the 2013 Breck Award from the International Zeolite AssociationSep 2013

Professor Michael Tsapatsis of CEMS and Jurgen Caro, professor of physical chemistry at Leibniz University received the 2013 Breck Award from the International Zeolite Association (IZA) for their pioneering work on the processing of zeolite and MOF nanostructures enabling separation membranes. Caro and Tsapatsis were presented with the prize at the Moscow International Zeolite Conference in July, in front of approximately one thousand conference participants. Established in 1983, the Breck Award is named for Donald W. Breck of the Union Carbide Corporation who was a major figure in the early development of synthetic molecular sieves and one of the founders of the IZA. During this meeting Tsapatsis was elected as IZA council member.
