Other tech: nanoscale superconducting wire for fast optical communication and long distance quantum encryption

Optical communication in space at 8X ethernet speeds and longer distance quantum encrypted communication could result from a better photon trap A photon trap. The heart of the detector, which has been around for a couple of years, is a wire 100 nanometers wide that meanders like coils on a refrigerator to increase the area …

Other Tech: Antimatter harvesting

Giant wire spheres may one day float near Earth, scooping up bits of antimatter for humans to use as space fuel. This is one of 12 recently selected to each receive up to $75,000 from the NASA Institute for Advanced Concepts. A plan is for antimatter to be collected using three concentric wire spheres. The …

Italians make fastest nanomotor

Italy’s has made the world’s fastest nanomotor – a molecular engine designed to carry drugs into cells. Vincenzo Balzani of Bologna University is the new engines designer. The engine, called Sunny because it runs on solar power, is a million times faster than the only other eco-friendly nanomotor, recently built in the Netherlands. The Netherlands …

Molecular electronics- carbon nanotubes linked by organic molecules in an electronic switch

In the Jan. 20, 2006, issue of Science, Columbia scientists explain how they have developed a unique way to connect the ends of carbon nanotubes by forming robust molecular bridges between them. The Columbia team was able to combine the best qualities of carbon nanotubes and organic molecules in a single electronic switch, the journal …

Deterministic chaos found and analyzed in atomic force microscope

Chaotic oscillations of microcantilever tips in dynamic Atomic Force Microscopy (AFM) are reported and characterized. Systematic experiments performed using a variety of microcantilevers under a wide range of operating conditions indicate that softer AFM microcantilevers bifurcate from periodic to chaotic oscillations near the transition from the non-contact to the tapping regimes. Careful Lyapunov exponent and …

Comparing CMOS versus rod-logic and other nanotechnology computing devices

When comparing the costs, performance, energy requirements the additional limitations of CMOS are that you still mainly have fairly large chips that have to be put into fairly large form factor devices. Rod-logic in a pure molecular manufactured systems would have far less size overhead. Rod-logic can be three-dimensional which greatly increases its likely performance. …

Part I : Semiconductor technology roadmap for 2005 – considers emerging nanotech

By the naming convention of these roadmaps…NEMS is rod logic. The emerging research devices section considers molecular devices, rod logic systems, nanotubes and nanowires and other nanotechnology related technology. Page 44 of the emerging research devices section. They define nano-electro-mechanical systems (NEMS) as rod logic.They have a conservative estimate of rod logic performance.They also assume …
