Das hat die Welt noch nicht gesehen: Ein Werkstoff, der quasi auf Knopfdruck seine Festigkeit aendert. Dieser Wandel in Sekundenschnelle kann durch Aenderungen der Elektronenstruktur eines Materials erreicht und so zum Beispiel aus einem festen und sproeden Stoff ein weicher und formbarer werden. Den entscheidenden Impuls liefern elektrische Signale, Clou dieser sensationellen Entwicklung.
A space flight by millions of microscopic worms could help us overcome the numerous threats posed to human health by space travel. The Caenorhabditis elegans (C. elegans) have also given experts an insight into how to block muscle degradation in the sick and elderly.
Antibiotics are among the greatest achievements of medical science. But lately the former multi-purpose weapon fails in the battle against infectious diseases. Bacteria are increasingly developing resistance to antibiotics. Researchers have now found a therapeutic equivalent which could replace penicillin and related phamaceuticals.
They see more than the naked eye and could make traffic safer: miniaturized thermal imaging sensors. But they are difficult to manufacture on a commercial scale. Researchers have now developed a new system. On it, special micro-electromechanical systems can be produced - with the correct etching technique.
Peizhen Kathy Lu, associate professor of materials science and engineering at Virginia Tech, is a 2011 recipient of the Friedrich Wilhelm Bessel Research Award presented by the Alexander von Humboldt Foundation.
A team of researchers from the University of Chicago and the U.S. Department of Energy's (DOE) Argonne National Laboratory has demonstrated a method that could produce cheaper semiconductor layers for solar cells.
Research without supercomputers is unimaginable nowadays. However, they increasingly represent an energy problem. Every single computer operation, especially deleting data, converts electrical energy into heat. For this reason, the latest research results by a team of physicists from Switzerland, England and Singapore deserve careful attention: under certain conditions, cold is generated instead of heat when deleting data. The only condition is that the content of the memory must be known "more than completely" during the deletion process. This is possible provided the so-called quantum-mechanical entanglement is included, since such entanglement carries more information than a classical copy of the data.
The seventh edition of nanoforum will take place on September 14-15, 2011, at Sapienza University of Rome. This event represents an excellent opportunity to get informed about the state of the art of nanotechnologies in Italy and abroad and to learn about the latest industrial applications, thanks to a large conference program and a specialized expo area.
With the curtain about to rise on a much-anticipated new era of "nanoagriculture" - using nanotechnology to boost the productivity of plants for food, fuel, and other uses - scientists are reporting a huge gap in knowledge about the effects of nanoparticles on corn, tomatoes, rice and other food crops.
