#Hybrid#dots#offer cheaper way to run fuel cells Last year chemist James Tour made graphene quantum dots from coal.

The lab discovered boiling down a solution of graphene quantum dots (GQDS) and graphene oxide sheets (exfoliated from common graphite) yielded self-assembling nanoscale platelets that could then be treated with nitrogen and boron.

#From coal, cheap quantum dots in one step Chemists have discovered how to reduce three kinds of coal into graphene quantum dots (GQDS) that could be used for medical imaging as well as sensing electronic and photovoltaic applications.

The report is online at Scientific Reports("Graphene quantum dots Interfaced with Single Bacterial Spore for Bio-Electromechanical devices:

and put graphene quantum dots on its surface --and then attached two electrodes on either side of the spore,"said Vikas Berry, UIC associate professor of chemical engineering and principal investigator on the study."

Graphene quantum dots made from coal, introduced in 2013 by the Rice university lab of chemist James Tour,

Tour said graphene quantum dots may prove highly efficient in applications ranging from medical imaging to additions to fabrics and upholstery for brighter and longer-lasting colors."

Graphene quantum dots are photoluminescent, which means they emit light of a particular wavelength in response to incoming light of a different wavelength.

#Graphene quantum dot LEDS Graphene is a 2d carbon nanomaterial with many fascinating properties that can enable to creation of next-generation electronics.

On the other hand, graphene quantum dots (GQDS), which are merely a few nanometers large in the lateral dimension, are shown to emit light upon excitation in the visible spectral range.

Seunghyup Yoo (Electrical engineering) have succeeded in developing LEDS based on graphene quantum dots. Highly pure GQDS were synthesized by an environmentally-friendly method designed by Prof.
