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
