Researchers precisely control nanowire position and orientation using fluid flow

Scientists from the the NIST Center for Nanoscale Science and Technology and the University of Maryland have used a combination of electric fields and fluid flow to precisely move and rotate nanowires, and have demonstrated that this method can be used to manipulate nanowires regardless of whether they are made from dielectric, semiconducting, or metallic materials.

Bose-Einstein condensates evaluated for quantum computers

A team of physicists at the Georgia Institute of Technology has examined how Bose-Einstein communication might work. The researchers determined the amount of time needed for quantum information to propagate across their BEC, essentially establishing the top speed at which such quantum computers could communicate.

Synchrotron used as a microscope to determine protein structure

A team led by David Reverter, a researcher at the Institute of Biotechnology and Biomedicine (IBB) of the UAB, has determined for the first time the three-dimensional structure of a protein pair: LC8 and Nek9. Depending on whether or not they bind, Nek9 ensures that the chromosomes group and separate correctly during cell division.

Nanotechnology explained: Nanowires and nanotubes

Nanowires and nanotubes, slender structures that are only a few billionths of a meter in diameter but many thousands or millions of times longer, have become hot materials in recent years. They exist in many forms - made of metals, semiconductors, insulators and organic compounds - and are being studied for use in electronics, energy conversion, optics and chemical sensing, among other fields.
