Rice fine-tunes quantum dots from coal
Graphene quantum dots made from coal, introduced in 2013 by the Rice University lab of chemist James Tour, can be engineered for specific semiconducting properties in either of two single-step processes. In a new study this week in the American Chemical Society journal Applied Materials & Interfaces, Tour and colleagues demonstrated fine control over the graphene oxide dots’ size-dependent band gap, the property that makes them semiconductors. Quantum dots are semiconducting materials that are small enough to exhibit quantum mechanical properties that only appear at the nanoscale. Tour’s group found they could produce quantum dots with specific semiconducting properties by sorting them through ultrafiltration, a method commonly used in municipal and industrial water filtration and in food production.

Data Structures Influence Speed of Quantum Search in Unexpected Ways
“We turned an intuition on its head,” Wong said. “Searching with a quantum particle, we showed the opposite, giving an example where searching in a city with low connectivity yields fast search, and an example where searching in a city with high connectivity yields slow search. Thus the quantum world is much richer than our classical intuitions might lead us to believe.”

Croll to receive Air Force Young Investigator Award
The NDSU research team is examining how randomly crumpled and purposefully folded polymeric materials eventually could be used as lightweight structural components in aerospace applications. The secrets of these bends and folds could provide information that leads to lightweight and strong components to make aircraft and spacecraft more efficient.
