A solar-powered sensor station to monitor in real time the concentration of gases that are key culprits in climate change and air pollution has been installed on a Queensland University of Technology Gardens Point roof as part of an international study on solar-powered environmental nano sensors.
Scientists were able to demonstrate how two remote atomic quantum systems can be prepared in a shared 'entangled' state. This means that one system is a single atom trapped in an optical resonator, and the other one is a Bose-Einstein condensate consisting of hundreds of thousands of ultracold atoms.
Empowered by a $1.2 million grant from the National Institutes of Health, Arizona State University scientist Wayne Frasch is deciphering how one of the world's smallest molecular motors works in living cells. In the process, he is also casting light on a physics puzzle that has perplexed scientists for more than 40 years.
Researchers demonstrate the world's thinnest polarizer, which relies on the coupling, guiding and polarizing of electromagnetic waves by graphene. They claim that this breakthrough will someday allow the integration on all-photonic circuits for high-speed optical communications.
Die bisherigen Standardtestverfahren fuer die Risikobewertung von Nanomaterialien sind ungenuegend. Zu diesem Ergebnis kommt eine Studie unter der Federfuehrung des Instituts fuer Umweltwissenschaften der Universitaet Koblenz-Landau.
Using a mechanical grinding technique that allowed them to control the structure of a metal's surface on the nanoscale, Ke Lu and colleagues from the Chinese Academy of Science's Institute for Metal Research in Shenyang have overcome the frustrating tradeoff between strength and brittleness to produce a protective copper surface that is both strong and ductile.
Stanford researchers have developed an improved imaging method using fluorescent carbon nanotubes that allows them to see centimeters deep into a mouse with far more clarity than conventional dyes provide. For a creature the size of a mouse, a few centimeters makes a great difference.
The National Physical Laboratory (NPL) in the UK is developing three optical techniques that use light scattering to make these measurements in solid polymers: frequency-domain optical coherence tomography (FD-OCT), Fraunhofer wavefront correlation (FWC) and oscillatory photon correlation spectroscopy (Os-PCS).
At the forefront of nanotechnology, researchers design miniature machines to do big jobs, from treating diseases to harnessing sunlight for energy. But as they push the limits of this technology, devices are becoming so small and sensitive that the behavior of individual atoms starts to get in the way. Now Caltech researchers have, for the first time, measured and characterized these atomic fluctuations - which cause statistical noise - in a nanoscale device.
Nanotechnology is opening up new markets and offering novel solutions to numerous challenges in a very varied range of areas. This was the tenor of the 1st Swiss NanoConvention which took place on May 18 and 19 in Baden.
