Batteries might gain a boost in power capacity as a result of a new finding from researchers at MIT. They found that using carbon nanotubes for one of the battery’s electrodes produced a significant increase — up to tenfold — in the amount of power it could deliver from a given weight of material, compared [...]

Sustainability Council: Nanotech Commercialisation Racing Ahead Of Safety Regulation
Posted by prabakaran on June 29th, 2010
Source: Voxy.com.nz – June 20, 2010 New Zealand women are being exposed to cosmetic products containing a typeof nanomaterial that has been stripped from the shelves in Europe and Australia. Products containing nanoparticles called “fullerenes” remain on sale in New Zealand even though the European cosmetics industry has pledged not to use them until more [...]
Greener Nanotech 2010: Navigating EHS for nanomaterials
Posted by prabakaran on June 29th, 2010
Source: Electro IQ – June 21, 2010 Greener Nanotech 2010 conference (June 16-18, U. of Oregon, Portland, OR) focused on both the importance of verifying that any nanomaterials products are safe for the environment and health, as well as importance of continuing to move beneficial side of nanomaterials forward. Oregon has been involved in green [...]
Comparison of the toxicity of silver, gold and platinum nanoparticles in developing zebrafish embryos
Posted by prabakaran on June 29th, 2010
Source: ICON – June, 2010 [...] Gold (Au-NP, 15–35 nm), silver (Ag-NP, 5–35 nm) and platinum nanoparticles (Pt-NP, 3–10 nm) were synthesized using polyvinyl alcohol (PVA) as a capping agent. Toxicity was recorded in terms of mortality, hatching delay, phenotypic defects and metal accumulation. [...] Among the nanoparticles studied, Ag-NPs were found to be the [...]
Fab Synchronization for producing advanced chips
Posted by prabakaran on June 29th, 2010
Four reputed companies have come together to synchronize semiconductor manufacturing program for producing advanced chips based on 28nm process technology. IBM, Samsung Electronics, ST Microelectronics and Global Foundries are working towards standardization of advanced 28nm process technology so those consistent products are made worldwide for various applications including electronics and device manufacturers.
The 28nm process technology, [...]
Towards improvement in the efficiency of the solar cell
Posted by prabakaran on June 29th, 2010
Solar energy is one of the major renewable sources of energy; however the major drawback of utilizing the energy is the conversion of it. The best nanowire solar cells available at present thin film solar cells of type III/IV and had a conversion efficiency of the order of 37 to 40 percent and researchers want [...]
Timely technology sees tiny transitions
Posted by prabakaran on June 29th, 2010
Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes. A new technique by Rice University researchers will allow them to track single molecules without modifying them — and it works over longer timescales.
Nanowires for the electronics and optoelectronics of the future
Posted by prabakaran on June 29th, 2010
The tale begins with a feasibility study on the manufacture of colored fluorescing thin films for optical safety applications. An EU project on the development of novel gas sensors followed. In the meantime, Empa researchers have successfully synthesized complex organic nanowires and managed to attach them together with electrically conducting links — the first step [...]
Researchers develop new method for mass-producing graphene
Posted by prabakaran on June 29th, 2010
Researchers at Rensselaer Polytechnic Institute have developed a simple new method for producing large quantities of the promising nanomaterial graphene. The new technique works at room temperature, needs little processing, and paves the way for cost-effective mass production of graphene.
Researchers create self-assembling nanodevices that move and change shape on demand
Posted by prabakaran on June 29th, 2010
By emulating nature’s design principles, researchers have created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand. Double helices fold up into larger, rigid linear struts that connect by intervening single-stranded DNA. These single strands of DNA pull the struts up into a 3D form. The resulting [...]
