Multiwalled Nanotubes Embedded in Cermanic Are a Lot Stronger

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 …

Maxing Out Vasimr Performance with Vapor Core Reactors or Nuclear Fusion

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 …

Google Using Dwave Systems Quantum Computer as a binary classifier of images

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 …
