Holographic Precise Mass Control of Nanoscale Particles (50 nanometers to 3 microns) with Re-arrangement in Seconds

Researchers at Purdue University have developed a technique that uses a laser and holograms to precisely position numerous tiny particles within seconds, representing a potential new tool to analyze biological samples or create devices using nanoassembly. The technique, called rapid electrokinetic patterning, is a potential alternative to existing technologies because the patterns can be more …

Thorium Google Talk and Jim Hansen Now a Thorium Proponent

Joe Bonometti, gave a Google Tech talk on liquid fluoride thorium reactors. 11MB of powerpoint slides “ Besides the low amount of waste and almost complete burning of all Uranium and Plutonium, another big advantage of liquid fluoride reactors is fast and safe shutoff and restart capability. This fast stop and restart allows for load …

Superconductor at 212K

Joe Eck at superconductors.org continues his research with superconductors and reports signs of superconductivity over 212K by doping a recently-discovered 200K tin-copper-oxide superconductor with a small amound of indium. The improved formula becomes (Sn5In)Ba4Ca2Cu10Oy. Although the 212K phase forms as a very small volume fraction within the bulk, sharp resistive and diamagnetic transitions are clearly …

Double to Triple the Energy Harvesting from Nanoscale Piezoelectrics

Dramatic enhancement in energy harvesting for a narrow range of dimensions in piezoelectric nanostructures around the critical size of 20-23 nanometer thick beams. Lead zirconate titanate (PZT) material employed in the form of cantilever beams, our results indicate that the total harvested power peak value can increase by 100% around 21 nm beam thickness (under …

Dwave Quantum Computer Performance Estimates and Calculations

From the Dwave presentation at SC08 (Supercomputer conference), they indicated that the current 128 qubit adiabatic quantum computer has sub-PC performance but they project by next year to reach that level with whatever number of qubits are operational then. Assuming the time scale is roughly correct between the 2008 and 2009 points then it will …
