Journal ArticleDOI
More than the Ions: The Effects of Silver Nanoparticles on Lolium multiflorum
Liyan Yin,Yingwen Cheng,Benjamin Espinasse,Benjamin P. Colman,Mélanie Auffan,Mark R. Wiesner,Jérôme Rose,Jie Liu,Emily S. Bernhardt +8 more
TL;DR: This study suggests that growth inhibition and cell damage can be directly attributed either to the nanoparticles themselves or to the ability of AgNPs to deliver dissolved Ag to critical biotic receptors.
Journal ArticleDOI
Long-Term Transformation and Fate of Manufactured Ag Nanoparticles in a Simulated Large Scale Freshwater Emergent Wetland
Gregory V. Lowry,Benjamin Espinasse,Appala Raju Badireddy,Curtis J. Richardson,Brian C. Reinsch,Lee D. Bryant,Audrey J. Bone,Amrika Deonarine,So-Ryong Chae,Mathieu Therezien,Benjamin P. Colman,Heileen Hsu-Kim,Emily S. Bernhardt,Cole W. Matson,Mark R. Wiesner +14 more
TL;DR: Assessment of the long-term behavior of poly(vinylpyrrolidone)-coated silver nanoparticles (AgNPs) in freshwater mesocosms simulating an emergent wetland environment finds that erosion and runoff is a potential pathway for AgNPs to enter waterways.
Journal ArticleDOI
Transport and Retention of Colloidal Aggregates of C60 in Porous Media: Effects of Organic Macromolecules, Ionic Composition, and Preparation Method
TL;DR: Variability in the method of preparing colloidal aggregates of fullerenes was observed to yield significant differences in nC60 properties and transport behavior, which are qualitatively consistent with trends anticipated by theory.
Journal ArticleDOI
On an experimental method to measure critical flux in ultrafiltration
TL;DR: In this paper, the authors present an improvement of previous techniques to determine critical flux in ultrafiltration, which allows having accurate values of the critical flux and the rate of irreversibility of the created deposit on the membrane.
Journal ArticleDOI
Emerging contaminant or an old toxin in disguise? Silver nanoparticle impacts on ecosystems.
Benjamin P. Colman,Benjamin Espinasse,Curtis J. Richardson,Cole W. Matson,Cole W. Matson,Gregory V. Lowry,Gregory V. Lowry,Dana E. Hunt,Mark R. Wiesner,Emily S. Bernhardt +9 more
TL;DR: The results suggest that all forms of Ag changed solute chemistry driving transformations of Ag which then altered Ag impacts, leading to a surprising convergence in the direction, magnitude, and duration of ecosystem-scale impacts for all Ag treatments.
