A bronze matryoshka doll: The metal in the metal in the metal
Just like in the Russian wooden toy, a hull of 12 copper atoms encases a single tin atom. This hull is, in turn, enveloped by 20 further tin atoms. Professor Faessler's work group at the Technische Universitaet Muenchen was the first to generate these spatial structures built up in three layers as isolated metal clusters in alloys. With their large surfaces these structures can serve as highly efficient catalysts.

Nanorod-assembled order affects diffusion rate and direction
Georgia Tech professor Rigoberto Hernandez studied the movements of a spherical probe amongst static nanorods. He found that the particles sometimes diffused faster in a nematic environment than in a disordered environment. That is, the channels left open between the ordered nanorods don't just steer nanoparticles along a direction, they also enable them to speed right through.

New investment aims to establish the UK as a global graphene research hub
Today sees the announcement of full details of how an additional £50 million will be spent to keep the UK at the forefront of research into 'wonder material' graphene. 200 times stronger than steel yet less than an atom thick, graphene is the strongest and thinnest material ever measured, and also the world's most conductive material. It has a wide range of potential uses, including electronics, flexible touch screens, sensors and in composite materials.

Self-assembling nanorods: Berkeley Lab researchers obtain 1-, 2- and 3-D nanorod arrays and networks
Berkeley Lab researchers have developed a relatively fast, easy and inexpensive technique for inducing nanorods to self-assemble into aligned and ordered macroscopic structures. This technique should enable more effective use of nanorods in solar cells, magnetic storage devices and sensors, and boost the electrical and mechanical properties of nanorod-polymer composites.

Ultra-fast photodetector and terahertz generator
Photodetectors made from graphene can process and conduct light signals as well as electric signals extremely fast. Within picoseconds the optical stimulation of graphene generates a photocurrent. Until now, none of the available methods were fast enough to measure these processes in graphene. Scientists at the Technische Universitaet Muenchen now developed a method to measure the temporal dynamics of this photo current. Furthermore they discovered that graphene can emit terahertz radiation.

Perfect nanotubes shine brightest
A painstaking study by Rice University has brought a wealth of new information about single-walled carbon nanotubes through analysis of their fluorescence. The researchers found that the brightest nanotubes of the same length show consistent fluorescence intensity, and the longer the tube, the brighter.

Bilayer graphene works as an insulator
A research team led by physicists at the University of California, Riverside has identified a property of "bilayer graphene" that the researchers say is analogous to finding the Higgs boson in particle physics. The physicists found that when the number of electrons on the BLG sheet is close to 0, the material becomes insulating – a finding that has implications for the use of graphene as an electronic material in the semiconductor and electronics industries.
