Researchers have managed to turn the oscillation direction of beams of light - simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical current.
In the remediation of pollutions in the soil and groundwater, minute nanoparticles are being increasingly used that are to convert resp. break down pollutants on site. The process, often somewhat mistakenly described as 'nano-remediation', can also be used with contaminations that have been hard to fight up to now, for example through heavy metals or the notorious, carcinogenic softener PCB. Yet how do the various nanoparticles behave in the earth, are they in turn harmless for humans and the environment and how can they be produced at a favourable price?
By designing droplets using electricity, researchers have opened new possibilities in physics. This technique could possibly be used for everything from extracting oil from wells to creating makeup and food.
A new ASTM International standard will facilitate the meaningful submission and exchange of nanomaterial descriptions and characterization data, along with other files, among individual nanotechnology researchers.
Researchers at Karolinska Institutet in Sweden have developed the first method for directly measuring the extent to which drugs reach their targets in the cell. The method could make a significant contribution to the development of new, improved drug substances.
Unique nanostructures on guillemot eggshells eggs enable them to survive precarious habitats, on exposed cliffs with no nest. A new study shows how these structures act as self-cleaning guardians of the eggs, preventing them from falling and protecting them from salt and guano exposure.
Samuel Lara-Avila has been awarded the Arne Sjögren prize for most innovative PhD thesis in the area of Nanoscience and Nanotechnology at Chalmers in 2012, for his thesis 'Magnetotransport characterization of epitaxial graphene on SiC'.
The Nanotechnology Knowledge Transfer Network, one of the UK's primary knowledge-based networks for Micro and Nanotechnologies, announced the availability of its free 2013 version of the UK Nanotechnology Health, Safety and Environment Directory.
