Graphene quantum dots dramatically improve the efficiency of organic solar cells

Graphene sheets have been shown to act as good acceptors when blended with conjugated polymers, but after blending, the photovoltaic characteristics of the polymers are considerably degraded. Scientists have now shown that the situation can be dramatically improved by blending polymers with graphene quantum dots instead of sheets.

Researchers find that disorder is key to nanotube mystery

So far, no one has managed to explain why, at the molecular level, a stable liquid would want to confine itself to such a small area. Now, using a novel method to calculate the dynamics of water molecules, Caltech researchers believe they have solved the mystery. It turns out that entropy, a measurement of disorder, has been the missing key.
