Polymer Structures Serve as “Nanoreactors” for Nanocrystals with Uniform Sizes and Shapes

Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures — including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal nanocrystals.

Air Force Announces Basic Research Awards

The Air Force Office of Scientific Research granted seven awards to various academic institutions to perform multidisciplinary basic research. The AFOSR awards, totaling $67.5 million, are the result of the Fiscal Year 2013 competition conducted by AFOSR, the Army Research Office, and the Office of Naval Research under the Department of Defense (DoD) Multidisciplinary University Research Initiative (MURI) Program.
