21st Century Innovative Technologies and Developments as also discoveries

There's big news in the world of tiny things.

New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts with something that's 1,000 times thinner than the typical human hair – a semiconductor nanowire.

Scientists are using a novel fabrication process to create ultra-efficient solar energy rectennas capable of harvesting more than 70 percent of the sun's electromagnetic radiation and simultaneously converting it into usable electric power.

===> "The solar power conversion device under development by this collaboration of two universities and an industry subcontractor has the potential to revolutionize green solar power technology by increasing efficiencies, reducing costs, and providing new economic opportunities," Zimmerman says. <===

Relier des connexions optiques ultrarapides à des processeurs ou des mémoires classiquement électroniques : c'est une voie de recherche activement explorée.

New research from the Max Planck Institute shows that silicon nanowires become doped with unexpectedly large amounts of aluminum during growth, increasing their conductivity and defying the laws of thermodynamics.

A tiny sponge in the boodstream could stop poisons from bacterial infections and snakes -- and might solve the problem of antibiotic resistance.

Un étudiant de 16 ans de Calgary au Canada a reçu mardi un prix pour ses recherches sur une thérapie utilisant des nano-particules d'or qui, injectées à un cancéreux et chauffées, tuent les cellules malades, a annoncé le laboratoire français...

La bioélectronique du futur pourrait bien reposer sur l’utilisation de transistors à effet de champ fabriqués avec du graphène.

Most flexible polymers are inherently flimsy. When you look at their micro-structures it's easy to see why: They look like piles of entangled spaghetti strands.

Nanotechnology has promised us a fantastic world where miniature factories would build devices atom by atom. A recent report describes a new kind of microactuator made from vanadium oxide.
