Researchers participating in the California NanoSystems Institute (CNSI) at the University of California at Santa Barbara (UCSB) and at Los Angeles (UCLA) have invented a new technique for producing "Ultra High Density Nanowire Lattices and Circuits"--the title of their paper being published expeditiously at 2:00 p.m. March 13 on the "Science Express" website, Science Magazine’s rapid portal for publication of significant research findings to appear subsequently in print in Science.
The method, for which a patent is pending, is akin to intaglio printmaking processes in which printing is done from ink below the surface of the plate. Intaglio processes emboss paper into the plate’s incised lines.
The CNSI nanowires are like the embossed ink on a paper substrate, except that the nanowires are much, much smaller than ink lines. Take, for instance, a grid of crossed nanowires. Each cross represents the element of a simple circuit! The nanowire junction density reported in the "Science Express" article is in excess of 1011 per square centimeter.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
