Norwegian researchers are among the first in the world to use radioactivity to trace nanoparticles in experimental animals and soil. Their findings have made it easier to identify any negative environmental impact of nanoparticles, which are found in an increasing number of products.
It's a clever bit of natural engineering that inspired imitation from a UW-Madison electrical and computer engineer, who has found a way to mimic the passive heliotropism seen in sunflowers for use in the next crop of solar power systems.
Quantum computers promise to reach computation speeds far beyond that of today's computers. As they would use quantum effects, however, they would also be susceptible to external interferences. Information flow into and out of the system is a critical point. Researchers from KIT with partners from Grenoble and Strasbourg have now read out the quantum state of an atom directly by using electrodes.
Quantencomputer versprechen Rechengeschwindigkeiten, die weit jenseits der Geschwindigkeit heutiger Computer liegen. Da sie Quanteneffekte nutzen würden, sind sie aber auch anfällig für Störungen von außen und der Informationsfluss in und aus dem System ist ein kritischer Punkt. Nun haben Forscher vom KIT mit Partnern aus Grenoble und Straßburg den Quantenzustand eines Atoms mittels Elektroden direkt ausgelesen.
Physicists have succeeded in using semiconductor nanostructures to produce single photons electrically and transfer them via a quantum channel. The application of these single photon sources is seen as further progress toward broader use in secure data communication.
A new study by researchers at the University of California, San Diego, and Emory University has uncovered fundamental details about the hexamer structures that make up the tiniest droplets of water, the key component of life - and one that scientists still don't fully understand.
A long-time staple of science fiction is the tractor beam, a technology in which light is used to move massive objects - recall the tractor beam in the movie Star Wars that captured the Millennium Falcon and pulled it into the Death Star. While tractor beams of this sort remain science fiction, beams of light today are being used to mechanically manipulate atoms or tiny glass beads, with rapid progress being made to control increasingly larger objects. Those who see major roles for optomechanical systems in a host of future technologies will take heart in the latest results from a first-of-its-kind experiment.
EU-funded scientists joined together to form a broad collaboration in nanomaterials research. The consortium sought to include European Member States and Candidate and potential Candidate Countries to develop a unified European Research Area.
Screening for toxicity of potential new drugs presents a bottleneck in the pharmaceutical industry. A European consortium addressed this issue by developing chip assays containing nanodrops of cells that could be used to screen various chemicals.
The Program Committee has announced that Nobel Laureate Sir Harold (Harry) Kroto will deliver the Pittcon 2013 Wallace H. Coulter Plenary Lecture, 'Exameter Objects to Nanometer Ones and Back Again'. The Plenary Lecture will be part of the Opening Session for the Technical Program at Pittcon 2013 which will be held in Philadelphia, Pennsylvania, March 17-21, 2013.
From July 19 to 23, scientists lined up samples of some of the largest known viruses on the planet for an extensive X-ray 'photo shoot' that may produce the highest-resolution 3-D images yet of these mysterious specimens - and bring researchers closer to understanding their functions and origins.
A new microscope to be built at the University of Houston will give scientists a better way to study the chemical properties of an array of surfaces, running the gamut from plastics and metals to cells and water. Researchers say this will help in both environmental studies and materials science.
For the first time, engineers at the University of New South Wales have demonstrated that hydrogen can be released and reabsorbed from a promising storage material, overcoming a major hurdle to its use as an alternative fuel source.
