New research may advance the nanoelectronics field
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory and their collaborators have discovered that a short, organic chain molecule with dimensions on the order of a nanometer (a billionth of a meter) conducts electrons in a surprising way: It regulates the electrons’ speed erratically, without a predictable dependence on the length of the wire. This information may help scientists learn how to use nanowires to create components for a new class of tiny electronic circuits.
The conducting chain molecule, or “nanowire,” that Smalley and his collaborators studied is composed of units of phenyleneethynylene (PE), which consists of hydrogen and carbon atoms. Like the links that make up a chain, PE units join together to form a nanowire known as oligophenyleneethynylene (OPE). PE, and therefore OPE, contains single, double, and triple carbon-carbon bonds.

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...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
