The breakthrough technology — called “silicon nanophotonics” — allows the integration of different optical components side-by-side with electrical circuits on a single silicon chip using, for the first time, sub-100nm semiconductor technology. Silicon … more… Silver nanocubes make super-light-absorbers December 10, 2012   Microscopic metallic cubes could unleash the enormous potential of metamaterials to absorb light, leading to more efficient and cost-effective large-area absorbers for sensors or solar cells, Duke University researchers have found. Metamaterials are man-made materials that have properties often absent in natural materials. They are constructed to provide exquisite control over the properties of waves, … more… When the first stars blinked on December 10, 2012   Researchers at MIT, the California Institute of Technology, and the University of California at San Diego have peered far back in time, to the era of the first stars and galaxies, and found matter with no discernible trace of heavy elements, such as carbon and oxygen. To make this measurement, the team analyzed light from … more… Seeing in color at the nanoscale December 10, 2012   A new microscopy tool from researchers at the Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) delivers exquisite chemical details with a resolution once thought impossible. The team developed the tool, which they call a “campanile,” to investigate solar-to-electric energy conversion at its most fundamental level, but their invention promises to reveal new … more… Breakthrough: compound generated by low carb/low-calorie diet blocks effects of aging December 10, 2012   Scientists at the Gladstone Institutes have identified a novel mechanism by which a type of low-carb, low-calorie diet — called a “ketogenic diet” — could delay the effects of aging: the compound  β-hydroxybutyrate (βOHB), a “ketone body” that is generated during a prolonged low-calorie or ketogenic diet. Blocking oxidative stress While ketone bodies such as … more… Graphene towers promise ‘flexi-electronics’ December 10, 2012   It can support 50,000 times its own weight, springs back into shape after being compressed by up to 80%, and has a density much lower than most comparable metal-based materials. It’s a new superelastic, 3D form of graphene developed at Monash University that can even conduct electricity, paving the way for flexible electronics, Nature News … more… Get ready for ads that follow you from one device to the next December 10, 2012   To make advertising pay as audiences move over to mobile devices, Drawbridge is using statistical methods that rely on anonymous data to track people as they move between their smartphones, tablets, and PCs, MIT Technology Review reports. Drawbridge works by looking at the cookie data that comes with a request from a mobile or desktop … more… Nanostructured ‘sandwich’ boosts solar-cell efficiency almost three times December 10, 2012   Princeton researchers have found a simple and economical way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power. The researchers, led by electrical engineer Stephen Chou, the Joseph C. Elgin Professor of Engineering, were able to increase the efficiency … more… New VIDEOS   XFF2012 PROMO Visit KurzweilAI.net You are currently subscribed to the KurzweilAI.net newsletter as *|EMAIL|* To unsubscribe, please click here.
