Metal mirrors made with extremely high precision and exactly positioned are the key elements of modern telescopes. A new production technique enables complex optical surfaces to be manufactured with excellent trueness of shape and hitherto unattained positional accuracy.
Light-emitting diodes are gaining ground: They are now being used as background lighting for displays. But the manufacturing of complex LED optics is still complex and expensive. A new technology is revolutionizing production: Large-scale LED components can now be manufactured cost-effectively.
Counterfeit products create losses in the billions each year. Beside the economic damages, all too often additional risks arise from the poor materials and shoddy workmanship of 'knock-off artists'. Yet with the aid of fluorescing dyes, materials can be individually tagged and identified with certainty.
On December 2 - 3, 2010 experts from all over the world will gather for the 7th NanoMed conference in Berlin to discuss the state of the art in biomedical applications of nanotechnology. This year's Focus Topic is Nanotechnology-Enabled Diagnosis and Treatment of Cancer.
The Beilstein-Institut, a non-profit foundation, launches a scientific journal in the area of nanotechnology and nanoscience. The 'Beilstein Journal of Nanotechnology' is an Open Access Journal, which is globally available and publishes the latest research results and reviews. Publishing in this Journal is offered without any fees for authors and readers. The call for papers starts on June 1, 2010.
When the first warm rays of springtime sunshine trigger a burst of new plant growth, it's almost as if someone flicked a switch to turn on the greenery and unleash a floral profusion of color. Opening a window into this process, scientists have deciphered the structure of a molecular 'switch' much like the one plants use to sense light.
There have been impressive advances in computational methods, allowing researchers to better understand biological and physiological systems at the atomic level. In its latest Perspectives in General Physiology series, the Journal of General Physiology (JGP) offers an in-depth look at several of these methods and the advantages of each as applied to membrane proteins, with special focus on ion channels.
A $3 million Ohio Third Frontier award to the University of Dayton Research Institute will fund the scale-up and production of a 'game-changing' new nanomaterial that will allow composites to multitask - a wind turbine tower that can de-ice its own blades in winter, or store energy to release on a calm day, powering a grid even when its blades are not moving.
A collaboration between researchers ha led to the discovery of a new self-assembly method for controlling the dimensions of cylinders created from polymer precursors which contain two chemically different segments joined together, so the length of the cylinders can be precisely controlled.
The silicon transistors in your computer may be replaced in ten years by transistors based on carbon nanotubes. This is what scientists at the University of Gothenburg are hoping - they have developed a method to control the nanotubes during production.
Researchers have theoretically developed and experimentally demonstrated that the artificial catalytic nucleic acids called DNAzymes and their substrates constitute a platform for the logic operations essential to computational processes.
