Researchers from North Carolina State University have found that applying a small electric field results in faster formation of ceramic products during manufacture at lower temperatures, and enhances the strength of the ceramic itself.
A team of Duke University chemists has perfected a simple way to make tiny copper nanowires in quantity. The cheap conductors are small enough to be transparent, making them ideal for thin-film solar cells, flat-screen TVs and computers, and flexible displays.
The mystery surrounding what happens when bubbles collide has finally been busted. And knowing how bubbles bounce apart and fuse together could improve the quality of ice-cream and champagne as well as increase efficiency in the mining industry.
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.
