"Researchers in the US have gained important new insights into how electrons travel through nanoscale metal wires. They discovered that the force with which electrons push atoms around in these structures is much stronger than previously thought -- which could help improve next-generation nanoelectronic components."
"Scientists have discovered the world's smallest superconductor, a sheet of four pairs of molecules less than one nanometer wide. The new study provides the first evidence that nanoscale molecular superconducting wires can be fabricated, which could be used for nanoscale electronic devices and energy applications."
Nanotube transistors are smaller, faster, and use less power than the silicon variety, but using them to make complex circuits is difficult because it is difficult to ensure the quality of every individual nanotube. Researchers at Stanford University have a new approach that may make complex circuits practical.
