NSF grant supports high-yield synthesis of nanorods

Ounce for ounce, gold nanorods that are commercially available cost about 7,000 times more than bulk gold, but that may change, thanks to an award-winning research program in the laboratory of Rice University chemist Eugene Zubarev.

Molecular self-assembly controls graphene-edge configuration

Scientists have discovered a new bottom-up fabrication method that produces defect-free graphene nanoribbons (GNRs) with periodic zigzag-edge regions. This method, which controls GNR growth direction and length distribution, is a stepping stone towards future graphene-device fabrication by self-assembly.

Electroluminescence from a single polymer chain

Researchers have succeeded in detection and spectral characterization of electroluminescence (EL) emission from single polyfluorene chains. This first report on detection of EL from one chain of a conjugated polymer was made possible by isolating individual polyfluorene chains in vertical cylinders of a phase-separated block copolymer.
