Study helps assess nanotechnology's impact on sustainable growth

In the United States alone, government and private industry together invest more than $3 billion per year in nanotechnology research and development, and globally the total is much higher. What will be the long-run economic returns from these investments, not only in new jobs and product sales, but also from improvements in sustainability? Georgia Institute of Technology researchers Philip Shapira and Jan Youtie helped answer that question through research presented March 27th at the International Symposium on Assessing the Economic Impact of Nanotechnology held in Washington, D.C.

Popcorn-shaped gold particles gang up on Salmonella

How about a test that identifies Salmonella in five minutes, so that shipments of lettuce can be confiscated before they reach the table? Scientists today described development and successful testing of just such a test in a presentation here at the 243rd National Meeting and Exposition of the American Chemical Society (ACS).

Writing graphene circuitry with ion 'pens'

The unique electrical properties of graphene have enticed researchers to envision a future of fast integrated circuits made with the one-carbon-atom-thick sheets, but many challenges remain on the path to commercialization. Scientists from the University of Florida have recently tackled one of these challenges - how to reliably manufacture graphene on a large scale.
