Karel participated in The North American Membrane Society 31st annual meeting “Membranes for sustainability” in Tempe, Arizona. He has presented an oral lecture on the topic of “Metal ions-doped ultrahigh flux composite GO-SWCNT membranes for efficient H2 separation and a poster of his doctoral student Saeed work on the topic of Magneto-responsive polycrystalline Co0.5Ni0.5FeCrO4: Synthesis, dispersion control, and its tunability into CTA polymer matrix under the augmented-magnetic field for CO2 capturing and H2 separation applications.
