Surface affinity: Applications of a functional assay for quantifying nanoparticle transport, aggregation, transformation and bio-uptake in complex systems

September 15, 2015

Mark R. Wiesner holds the James L. Meriam Chair in Civil and Environmental Engineering at Duke University where he has appointments in the Pratt School of Engineering and the Nicholas School of Environment. He serves as Director of the National Science Foundation’s Center for the Environmental Implications of NanoTechnology (CEINT) and Chair of the Department of Civil and Environmental Engineering at Duke. Dr. Wiesner’s research established the area of environmental nanotechnology, examining the application of nanotechnologies for environmental quality control and the possible environmental implications of nanomaterials. He co-edited/authored the book “Environmental Nanotechnologies” and serves as Associate Editor of the journals Nanotoxicology and Environmental Engineering Science.  Professor Wiesner also pioneered research in the area of applications of low-pressure membranes to water treatment. He co-edited and -authored the book “Water Treatment Membrane Process,” served as the founding Chair of the American Water Works Association’s Membrane Research Committee, and serves on the editorial board of the journal Desalination. Professor Wiesner is a Fellow of the American Society of Civil Engineers, the American Association for the Advancement of Science, the Association of Environmental Engineering Professors (AEESP), and the International Water Association. Wiesner is a former President of AEESP, a de Fermat Laureate (2004) and the 2011 recipient of the Clarke Water Prize for his work in improving water quality through advancements in membrane and nanotechnology research. He was elected to the National Academy of Engineering in 2015.

 

A seminar has been co-organized by the departments of Civil and Environmental Engineering and Chemical Engineering on September 15th at 11:00am. Wiesner_flyer

There will be a reception prior to the seminar, with networking opportunities for interested faculty and students.

At the seminar Dr. Wiesner will discuss research conducted at the NSF funded Center for Environmental Implication of Nanotechnology (CEINT), led by Duke University . He will discuss their investigations on the relationship between surface properties of nanomaterials and their behavior in environmental systems. In particular, he will  address the use of a functional assay for surface affinity, the methods for quantifying surface affinity, and systems where surface affinity is likely to be important in predicting nanoparticle exposure and health effects.
