Graphene: Negative does not mean bad
Organic, carbon-based and soft materials
Doping graphene with nitrogen to generate negative carriers can be achieved through irradiation and annealing in ammonia. |
|
Semiconductors: Ultraviolet and ultra-powerful
Optics, photonics and optoelectronics
Injecting a beam of electrons directly into a semiconductor light-emitting device makes for a high-efficiency source of ultraviolet radiation. |

Conformation and physics of polymer chains: a single-molecule perspective p134
M. Vacha and S. Habuchi
Single-molecule optical detection and spectroscopy has enabled the structural and dynamical characterization of materials on nanometer scales, and can be used to study the relationship between the structure and properties of individual polymer chains. |

|
Designing green, self-healing coatings for metal protection p142
A. E. Hughes, I. S. Cole, T. H. Muster and R. J. Varley
Metal protection and repair after damage, either by corrosion or mechanical stress, is a crucial issue for a wide variety of applications. Environmental and health concerns have recently driven new research towards strategies involving ‘green’ corrosion inhibitors and self-repairing coatings. |

High-performance nanostructured thermoelectric materials p152
J.-F. Li, W.-S. Liu, L.-D. Zhao and M. Zhou
Thermoelectric materials, which interconvert a temperature gradient to a voltage, are attractive for power generation and heating/cooling applications. Recent developments have focused on the relationship between nanostructures and thermoelectric properties. |
