Advanced Materials : Engineering Strong Intergraphene Shear Resistance in Multi-walled Carbon Nanotubes and Dramatic Tensile Improvements Strong intergraphene shear resistance is engineered in multi-walled carbon nanotubes (MWCNTs) by embedding the nanotubes into a compressive-stressing ceramic environment to exploit the exceptional strength of its inner graphene walls during tensile loading. A dramatic enhancement in the tensile …
University of California, Riverside (UCR) Professor of Electrical Engineering and Chair of Materials Science and Engineering Alexander Balandin is leading several projects to explore ways to use the unique capabilities of graphene “quilts” as heat conductors in high-power electronics. Most of the current research on graphene has focused on its electronic properties and graphene’s potential …
Some comments on Vasimr by Paul March on the Nasa Forum Vasimr has different quoted exhaust velocity ranges for different propellants – * argon has a limit of around 50,000 m/s * 300,000 m/s is possible with hydrogen. The 39 day mission to Mars using VASIMR propulsion takes 200 Megawatts total input power driving 4-to-8 …
1. Above is a piece of the 370 megapixel image of 500,000 galaxies. Phil Plait, the bad astronomer, discusses the huge image just released by the Canada-France-Hawaii Telescope Legacy Survey Deep Field #1, a ginormous mosaic of the night sky. It covers a solid square degree of sky — 5 times the area of the …
Google is researching Quantum Computer Algorithms using Dwave Systems Quantum Computers for a binary classifier of images At the Neural Information Processing Systems conference (NIPS 2009), we show the progress we have made. We demonstrate a detector that has learned to spot cars by looking at example pictures. It was trained with adiabatic quantum optimization …
Intensive reading programs can produce measurable changes in the structure of a child’s brain, according to a study in the journal Neuron. The study found that several different programs improved the integrity of fibers that carry information from one part of the brain to another. They used a special type of MRI to look at …
Ames Laboratory research team discovers a new use for metamaterials that promises to eliminate mechanical friction in nanotechnology The groundbreaking research, conducted through mathematical simulations, revealed the possibility of a new class of materials able to exert a repulsive force when they are placed in extremely close proximity to each other. The repulsive force, which …
A webcast (FBR Capital Market conference) updates the situation with Blacklight Power They are now indicating that they will have continuous run prototypes in 2010. This is a delay from previous talk about a commercial system in 2009. However, if they make their continuous run prototypes with 50KW to 75KW of power available for independent …
1. Japan’s first ever nuclear power reactor to use mixed oxide (MOX) fuel assemblies is now operating at full capacity, fuel supplier Areva has announced. Kyushu’s Genkai 3 was loaded with the fuel fabricated from uranium and the plutonium recovered from previously used nuclear fuel in October. Recycling of plutonium in MOX is to play …
1. The Russian uranium mining company Atomredmetzoloto (ARMZ) plans to buy uranium assets in Namibia In 2008, Atomredmetzoloto (ARMZ), Russia’s leading uranium producer, planned to increase production in Russia and Kazakhstan by 12% to 4,300 metric tons (for 2009) ARMZ manages all of Russia’s uranium mining assets and also participates in uranium production in the …
HPCWire highlights of SC09 * 15 of 60 press releases were GPU related* China’s GPU-CPU “Tianhe” supercomputer making it into the number 5 position on the TOP500* Japan’s 3 petaflop TSUBAME 2.0 Fermi-equipped super scheduled for deployment in October 2010* announcement of a new GPU computing collaboration network.* HPC-capable Fermi GPUs from NVIDIA coming online …
