A status of temporal trends of persistent organic pollutants in Arctic biota

February 1, 2019
Author(s)
Frank Riget, Anders Bignert, Birgit Braune, Maria Dam, Rune Dietz, Marlene Evans, Norman Green, Helga Gunnlaugsdottir, Katrin S. Hoydal, John Kucklick, Robert Letcher, Derek Muir, Stacy Schuur, Christian Sonne, Stern Gary, Gregg Tomy, Katrin Vorkamp, Simon Wilson
More than 1000 time-series of persistent organic pollutants (POPs) in Arctic biota from marine and freshwater ecosystems some extending back to the beginning of 1980s were analyzed using a robust statistical method. The Arctic area encompassed extended

Performance of van der Waals Corrected Functionals for Guest Adsorption in the M 2 (dobdc) Metal-Organic Frameworks

April 24, 2017
Author(s)
Bess Vlaisavljevich, Johanna Huck, Zeric Hulvey, Kyuho Lee, Jarad A. Mason, Jeffrey B. Neaton, Jeffrey R. Long, Craig Brown, Dario Alfe, Angelos Michaelides, Berend Smit
Small molecule binding in metal-organic frameworks (MOFs) can be accurately studied both experimentally and computationally, provided the proper tools are employed. Herein, we compare and contrast properties associated with guest binding with density
