Registration is now open for a December 7, 2016, National Nanotechnology Initiative (NNI) webinar, “Water Sustainability through Nanotechnology: Increasing Water Availability.” NNI states that water demand in the U.S. is projected to increase over the next several decades. In addition to increased demand, many U.S. aquifers are being depleted at unsustainable rates, which may lead to increased challenges in locating usable water sources in the future. During the webinar, panelists Qilin Li (Rice University), Isabel Escobar (University of Kentucky), and David Mazyck (University of Florida) will describe current technologies and future opportunities related to water treatment and purification. The speakers will address filtration and membrane separation systems, catalysis, and alternatives to reverse osmosis. Webinar viewers will be able to submit questions for the panelists to answer during the question and answer period. Submitted questions will be considered in the order received and may be posted on the NNI website.
