Welcome to the STREAMS group!
The research group “Surface Transport and Reactive Events Affecting Membrane Separation” (STREAMS) is based at Bielefeld University and funded by the German Chemical Industry Association (VCI) in the framework of the Liebig Fellowship awarded to Dr. Petr Dementyev. From air separation to seawater desalination, membrane technologies are of paramount importance for numerous practical applications while membranes themselves span a wide range of organic, inorganic, and hybrid materials. Given the semipermeable nature of membranes, their performance is generally governed by the bulk properties, such as diffusion and sorption coefficients. However, active layers of many modern membranes are so thin, that mass transfer in the near-surface region becomes one of the key factors in separation. At STREAMS, we are dedicated to studying physicochemical processes occurring at membrane surfaces, including elementary reaction steps and surface diffusion. To this end, we employ two-dimensional materials as model systems which have virtually no internal volume and allow for exploring solely the surfaces of membranes. Curious to learn more?
