Creating New Science and Technology.
5
NSECs are creating new paradigms for
interdisciplinary research!
From NSF Committee of Visitors Review,
2004 Two significant and enduring results have
emerged from this investment .. the creation of
a nanoscale science and engineering community,
and the fostering of a strong culture of
interdisciplinary research
6
Providing Outreach and Education
