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.

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.

Researchers have begun crystallizing light as part of an effort to answer fundamental questions about the physics of matter. As part of an effort to develop exotic materials such as room-temperature superconductors, the researchers have locked together photons, the basic element of light, so that they become fixed in place.

Artificial membranes mimicking those found in living organisms have many potential applications ranging from detecting bacterial contaminants in food to toxic pollution in the environment to dangerous diseases in people. Now a group of scientists has developed a way to create these delicate, ultra-thin constructs through a 'dry' process, by evaporating two commercial, off-the-shelf chemicals onto silicon surfaces.

Researchers have married two unconventional forms of carbon to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.

Scientists have studied the electronic characteristics of a newly synthesized molecule, composed of two forms of carbon: a fullerene (C60) and a nano-aggregate of diamond. This study reveals exceptional electronic properties for this molecule, given it conducts electrical power into one direction but not into the opposite sense.
