Penn State will receive $4.2 million over the next three years from the National Science Foundation to continue the work of the National Nanotechnology Applications and Career Knowledge Network (NACK Network), founded at the University with a four-year grant from the NSF in 2008. The NACK Network provides national coordination of workforce development programs and activities on behalf of NSF in an effort to meet industry needs for skilled micro- and nanofabrication workers. The market value of U.S. products incorporating nanotechnology will total $1 trillion by the year 2020, according to an NSF report, and nanotechnology's share of the gross domestic product (GDP) will be 5.0 percent. The nation in 2020 will require 2 million people in the primary workforce engaged in nanotechnology production.
