Small Size Enhances Charge Transfer in Quantum Dots
In a study just published in the journal Chemical Communications, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory, Stony Brook University, and Syracuse University show that shrinking the core of a quantum dot can enhance the ability of a surrounding polymer to extract electric charges generated in the dot by the absorption of light.

UNIST research team opens graphene band-gap
Ulsan National Institute of Science and Technology (UNIST) announced a method for the mass production of boron/nitrogen co-doped graphene nanoplatelets, which led to the fabrication of a graphene-based field-effect transistor (FET) with semiconducting nature. This opens up opportunities for practical use in electronic devices.

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.
