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 …
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 …
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 …
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 …
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 …
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. …
The International technology roadmap for Semiconductors2005 edition Emergy Research devices http://www.itrs.net/Common/2005ITRS/ERD2005.pdf There is an very interesting technology performance assessment pg48-55Nano-floating gate memory(pg50), engineered tunnel barriermemory(pg50), 1D logic structures (pg53) (carbon nanotubes andnanowires) seem to be the leading candidates based on this assessment. Table 55 on page 8compares the current technology capabilities in 2005 andthe projected …
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 …
eMagin Corp. has developed a wearable headset system that plugs into Apple Computer’s video iPod and displays video from it in front of one eye, using optical technology designed to give the picture a higher resolution and make it appear larger than on the iPod’s screen. Using the EyeBud headset is akin to watching a …
