Scientists report that they could observe experimentally the current flow along channels at the crystal surfaces of topological insulators. The channels are less than one nanometer wide and extend along atomic steps of the crystal lattice. The scientists demonstrated also how these steps can be introduced in any arrangement.
The first semi-liquid, non-protein nucleating agent for automated protein crystallization trials is described. This 'smart material' is demonstrated to induce crystal growth and will provide a simple, cost-effective tool for scientists in academia and industry.
Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists have succeeded in capturing the first-ever snapshot of this dual behavior.
A University of Cincinnati research partnership is reporting advances on how to one day make solar cells stronger, lighter, more flexible and less expensive when compared with the current silicon or germanium technology on the market.
Researchers are investigating the manipulation of light in plasmonic nanostructures using the dephasing and population dynamics of electron-hole-pairs in metal coated, core-shell semiconductor nanowires. The technique would minimize energy loss and heat production.
Researchers designed a novel device based on graphene and metal nanoparticles that shows greatly enhanced response to light and is colour sensitive. This may foster applications like colour based ultra-sensitive photodetectors, efficient solar cells and detection of single molecules.
The overall goals of EFSA's Nano Network are to provide a forum for dialogue among participants; build mutual understanding of risk assessment principles; enhance knowledge on and confidence in the scientific assessments carried out in EU; and to provide increased transparency in the current process among Member States and EFSA on nanotechnology. All this with the aim to raise the level of harmonisation of the risk assessments developed in the EU on nanotechnology.
A way to link benzene rings together in a highly ordered three-dimensional helical structure using a straightforward polymerization procedure has been discovered, potentially opening up new areas of nanocarbon and materials science.
