Gold nanospheres show a path to all-optical computing.

New research, however, may enable engineers to build nanoscale antennae that turn light into a different sort of wave that can move through metal; the result could be data transmission speeds that are orders of magnitude higher than today’s. The key to the approach is a gold sphere just 50 nanometers in diameter. A Rice …

DNA self-assembly used to mass-produce patterned nanostructures

Duke University scientists have used the self-assembling properties of DNA to mass-produce nanometer-scale structures in the shape of a 4×4 grids, on which patterns of molecules can be specified. They said the achievement represents a step toward mass-producing electronic or optical circuits at a scale 10 times smaller than the smallest circuits now being manufactured. …

Richard Jones lays out the hurdles to his belief in Diamondiod nanotechnology

Richard Jones has proposed 6 experiments for validating his belief in diamondoid nanotechnology 1. Stability of nanoclusters and surface reconstruction.2. Thermal noise, Brownian motion and tolerance.3. Friction and energy dissipation.4. Design for a motor.5. The eutactic environment and the feed-through problem.6. Implementation path. It seems that Richard Jones has clearly outlined his areas of concern …

DNA wires made and formed into patterns

Ohio State University researchers have invented a process for uncoiling long strands of DNA and forming them into precise patterns. Ultimately, these DNA strands could act as wires in biologically based electronics and medical devices They used a tiny rubber comb to pull DNA strands from drops of water and stamp them onto glass chips. …

Other technology: plastic circuits, pre-nano desktop manufacturing

At Sarnoff Corporation in Princeton, NJ, and Columbia University, researchers have succeeded in operating circuits at 100 megahertz — as much as a hundred times faster than previous ones on plastic. The Sarnoff/Columbia advance could lead to displays measuring three meters or more diagonally that can also be rolled up and easily transported. 10-100 times …

New tool – grows carbon nanotubes at room temperature

CEVP has developed a fabrication tool to commercialise the revolutionary low temperature carbon nanotube growth process developed by the University of Surrey’s (UniS) Advanced Technology Institute (ATI). The new tool – NanoGrowth – is currently being trialled and characterised by UniS, and the two partners anticipate releasing the technology for commercial use in March 2006. …

Polyyne : background info on triple bonded carbon

Polyyne-containing carbon has attracted attention as a new type of carbon material for its unique triple-bond linear structure. It is recognized not only as a new carbon but also as a precursor for the preparation of new types of carbon materials. The polyyne-containing carbon was prepared by electrochemical reduction of a polytetrafluoroethylene (PTFE) film with …
