How to put more bang in your biofuels? Nanoparticles! A new study shows that the addition of alumina nanoparticles can improve the performance and combustion of biodiesel, while producing fewer emissions.
Vom 7. bis 9. April 2011 findet im Bernhard-Nocht-Institut fuer Tropenmedizin in Hamburg erstmals ein Symposium des Sonderforschungsbereiches 841 "Leberentzuendung: Infektion, Immunregulation und Konsequenzen" (SFB 841) statt.
IBM's announcement of the first biodegradable nanoparticles that can seek out and destroy drug-resistant bacteria caps off a century of healthcare and life sciences innovation from IBM. To celebrate IBM's Centennial, the company is unveiling an "icon of progress" representing IBM's contributions to fighting infectious diseases and contributions to world health.
Proof of the quantum wave nature of large organic molecules has been reported by an international team of physicists. The findings may be a step towards reducing quantum interference on a bigger scale than previously achieved.
To encourage and inspire more young women to pursue careers in science, Argonne will host its 24th annual Science Careers in Search of Women Conference on April 14, 2011, welcoming approximately 350 high school students from across the Chicago area to experience science and engineering first hand.
Dr. Simon Elliott from the Tyndall National Institute in Ireland is coordinating the EU research project REALISE and working on the next generation of USB flash memories. Rare earth oxides have been introduced to improve their storage capacity.
On 7 April 2011, Empa's new laser centre, which houses the only UV laser facility of its kind in the world, was opened in Thun. The facility will help researchers to develop new kinds of surfaces. Commercial partners will be able to use it to structure large films with micro to nanometre precision.
It's found only in the tails of sperm. It takes seven genes to build it. It gets activated as the sperm gets closer to the egg, giving it that extra whip and thrust to make it across the finish line. David Clapham, its discoverer, named it CatSper. Blocking it could literally make sperm impotent. This could be the basis of a new contraceptive gel or a pill that could be used by men or women.
Graphen gilt wegen seiner physikalischen und chemischen Eigenschaften als eines der vielversprechendsten neuen Materialien. Wissenschaftler haben jetzt ein Verfahren entwickelt, das es erlaubt, Bauelemente aus Graphen mithilfe einer integrierten Elektrode gezielt anzusteuern - eine wichtige Voraussetzung fuer industrielle Anwendungen.
In an interesting feat of nanoscale engineering, researchers at Lund University in Sweden and the University of New South Wales have made the first nanowire transistor featuring a concentric metal 'wrap-gate' that sits horizontally on a silicon substrate.
The arrays of fine adhesive hairs or 'setae' on the foot pads of many insects, lizards and spiders give them the ability to climb almost any natural surface. Research by James Bullock and Walter Federle from the University of Cambridge in England found that the different forces required to peel away these adhesive hairs from surfaces are what allows beetles to adhere to diverse surfaces, thereby reducing the risk of detachment.
When it comes to packaged fish or meat, it is nearly impossible to distinguish between fresh goods and their inedible counterparts. Researchers have now developed a sensor film that can be integrated into the package itself, where it takes over the role of quality control. And if the food has spoiled, it changes color to announce the fact.
Elsevier, a world-leading publisher of scientific, technical and medical information products and services, today announced the launch of the "Apps for Science" challenge, an international competition challenging software developers to create customized applications that enhance information search and discovery for researchers.
