President’s Council of Advisors on Science and Technology (PCAST) Review of the NNI for 2017 (letter report)

Subject Area:
External Evaluations of the NNI
Author: President’s Council of Advisors on Science and Technology (PCAST)
Publication Date: Jan. 17 2017

Description:

The President’s Council of Advisors on Science and Technology released its most recent review of the National Nanotechnology Initiative in a letter report, stating “The NNI has created a foundation for researchers to unearth the scientific secrets of the smallest scale and begin to amplify them into reimagined devices, systems, and new ways of engineering that will address some of the Nation’s greatest challenges.”


Nanotechnology Fact

Nanotechnology encompasses science, engineering, and technology at the nanoscale, which is about 1 to 100 nanometers. Just how small is that? A nanometer is one-billionth of a meter. For reference, a sheet of paper is about 100,000 nanometers thick. Nanoscale matter can behave differently than the same bulk material. For example, a material’s melting point, color, strength, chemical reactivity, and more may change at the nanoscale.

Researchers seeking to understand the fundamentals of properties at the nanoscale may call their work nanoscience; those focused on effective use of the properties may call their work nanoengineering. Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at the nanoscale.
