NNI Structure and Activities
EPA Strategies and Activities
EPA-sponsored Research
Looking Forward
National Nanotechnology Initiative
EPA is a member of the subcommittee – Nanoscale Science Engineering and Technology
Federal agencies and departments that participate in NNI Established in 2001 Responsible for coordinating federal government’s nanoscale research and development programs National Nanotechnology Coordinating Office (NNCO) – secretariat point of contact
Definition of Nanotechnology?
The ability to extract large sums of money from a decreasing federal research budget?
The development of novel properties for any business with “nano” prefix?
The capacity to manipulate at the nano level to multiply exponentially the number of nano meetings?
The understanding and control of matter at
dimensions of roughly 1 to 100 nanometers;
Where unique phenomena enable novel application

Unique Properties of Nanoscale Materials
Chemical reactivity of nanoscale materials greatly different from more macroscopic form e.g. gold
Vastly increased surface area per unit mass e.g. upwards of 100 m2 per gram
Quantum size effects result in unique mechanical electronic photonic and magnetic properties of nanoscale materials
New chemical forms of common chemical elements e.g. fullerenes nanotubes of carbon titanium oxide zinc oxide other layered compounds
