On Thursday past, the AECOM® Technology Corporation {NYSE:ACM} hosted a webcast update - THE ROLE OF NANOTECHNOLOGY IN ENVIRONMENTAL REMEDIATION & POTENTIAL RISKS - highlighting bioremediation techniques, strategies, and systems involving nano-scaled zero valent iron {nZVI} applications on contaminated groundwater and soils.

AECOM's environmental practice Nanotechnology Initiative Director, Bill Looney, quite forthrightly addresses nanoOEHS challenges and concerns regarding surface/catalytic/magnetic properties while disclosing risk mitigation measures undertaken globally by AECOM®. 

Matt Zenker, PE, PhD and Dora Chiang, PE, PhD discuss and display data from their respective in situ pilot projects, performance results, comparative bench-scale observations, and conclusions {including life-cycle cleanup costs}.

{Zenker's Site 1 results commence circa 18:24, page 16; Chiang's Site 2 toxicity/persistence/mobility/treatability controls commence circa 27:12, page 22}.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at
