The Berkeley team is now developing a way to improve the density of carbon nanotube/metal contacts. Their technique should also be applicable to single and multi-layer graphene devices, which face the same cooling issues.
Cooling microprocessor chips through the combination of carbon nanotubes and organic molecules as bonding agents is a promising technique for maintaining the performance levels of densely packed, high-speed transistors in the future.

The Mars stone нasa joke is an amazing one. According to Independent Squyres said that Quote [ it was “somehow flicked out ...]; please note that it flicked out right into the dust outlined area of the picture Sol 3528, what an amazing random smurfish fitting. It looks like the number of fans of the Flicker (1/f, 1/Omega) Noise theory grows in the world.
Nasa says Mars mystery rock that ‘appeared’ from nowhere is ‘like nothing we’ve ever seen before’
Postedby Thomas Anderson Meyer had been investigating DSPECs for years at the Energy Frontier Research Center at UNC and before. His design has two basic components: a molecule and a nanoparticle. The molecule, called a chromophore-catalyst assembly, absorbs sunlight and then kick starts the catalyst to rip electrons away from water. The nanoparticle, to which thousands of chromophore-catalyst assemblies are tethered, is part of a film ofnanoparticlesthat shuttles the electrons away to make the hydrogen fuel.
However, even with the best of attempts, the system always crashed because either the chromophore-catalyst assembly kept breaking away from thenanoparticlesor because the electrons couldn’t be shuttled away quickly enough to make hydrogen.
To solve both of these problems, Meyer turned to the Parsons group to use a technique that coated the nanoparticle, atom by atom, with a thin layer of a material called titanium dioxide. By using ultra-thin layers, the researchers found that the nanoparticle could carry away electrons far more rapidly than before, with the freed electrons available to make hydrogen. They also figured out how to build a protective coating that keeps the chromophore-catalyst assembly tethered firmly to the nanoparticle, ensuring that the assembly stayed on the surface.
With electrons flowing freely through the nanoparticle and the tether stabilized, Meyer’s new system can turn the sun’s energy into fuel while needing almost no external power to operate and releasing no greenhouse gases. What’s more, the infrastructure to install these sunlight-to-fuel converters is in sight based on existing technology. A next target is to use the same approach to reduce carbon dioxide, a greenhouse gas, to a carbon-based fuel such as formate or methanol.

http://www.rdmag.com/news/2014/01/research-lays-out-theory-metamaterial-acts-analog-computer A study by researchers at the Univ. of Pennsylvania, the Univ. of
Texas at Austin and Univ. of Sannio in Italy, shows that metamaterials
can be designed to do photonic calculus as a light wave goes through
them. A light wave, when described in terms of space and time, has a
profile in space that can be thought of as a curve on a Cartesian plane.
The researchers’ theoretical material can perform a specific
mathematical operation on that wave’s profile, such as finding its first
or second derivative, as the light wave passes through the material.
