Greenhouse gas could become clean fuel - 22 April 2009 - New Scientist - 0 views

  •  
    CONVERTING a greenhouse gas into a clean-burning fuel offers two benefits for the price of one. That's the thinking behind a novel process for converting carbon dioxide into methanol at room temperature, developed by a team at the Institute of Bioengineering and Nanotechnology in Singapore (Angewandte Chemie International Edition, DOI: 10.1002/anie.200806058).

Magnetic Particles of Gold, Silver and Copper Produced - 0 views

  • An international team led by Physics and Chemistry teams from the Faculty of Science and Technology at the University of the Basque Country (UPV/EHU) and directed by Professor Jose Javier Saiz Garitaonandia, has achieved, by means of a controlled chemical process, that atoms of gold, silver and copper - intrinsically non-magnetic (not attracted to a magnet) - become magnetic. The article has been published in the February issue of the prestigious international magazine in nanotechnology, Nanoletters (Vol.8, No. 2, 661-667 (2008).

Stanford's nanowire battery holds 10 times the charge of existing ones - 0 views

  • Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices. The new version, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. A laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers.

Nanosolar's Breakthrough - Solar Now Cheaper than Coal » Celsias - 1 views

  • They have successfully created a solar coating that is the most cost-efficient solar energy source ever. Their PowerSheet cells contrast the current solar technology systems by reducing the cost of production from $3 a watt to a mere 30 cents per watt. This makes, for the first time in history, solar power cheaper than burning coal.

Technology To Do Away With Batteries | Got2BeGreen - 0 views

  • The Nanogenerator uses a technique of lining up zinc oxide nanowires inside of a special electrode. Tiny filaments are sent into movement by natural forces like blood flow, walking, mechanical vibration or ultrasonic waves. The devices are so minuscule that thousands of them could fit on a head of a pin.

Nanomaterial Being Produced By the Ton - 0 views

  • Graphene is an extremely low density material, almost an atomic-scale chicken wire made of carbon atoms and their bonds. It has been the focus of much research because of its exceptional electrical, mechanical and optical properties. It holds great promise in renewable energies. Among the so far underutilized advantages Graphene offers are that it is fifty times stronger than steel, and it has five times the conductivity of copper, with only one quarter of the density.
  •  
    Because of its light weight Graphene is the ideal substitute for copper for aerospace defense against emerging weapons technologies such as electromagnetic pulse as well as lightning strike protection for the aerospace market.

IEEE Spectrum: Silicon Nanowires Turn Heat to Electricity - 0 views

  • Two separate teams, one at Caltech and the other at the University of California, Berkeley, reported that they could increase silicon's ability to convert heat into electric current by as much as 100 times. If they can use what they've learned to improve silicon even further, or translate their findings to other materials, the discovery could lead to new ways to cool computer chips, build refrigerators, or get more power out of car engines.
