Super Molecules Could Speed Up Internet

Posted in News, Science by Chris Weber on January 3rd, 2007

chromophore light molecule breakthroughMolecules that have the peculiar characteristic of being extra sensitive to light could have wide ranging implications on the field of computing.

The Kuzyk Limit was first theorized by Washington State University Professor Mark Kuzyk in 1999. Kuzyk’s find showed how molecules interacted with light and showed the possibility of creating molecules that could be much more reactive than any material at that time.

A Chinese chemist Yuxia Zhao was the first to synthesize such a molecule at the Chinese academy of science. The molecules react up to fifty percent more than any previously known material.

The synthesized material is known as a chromophore. When light hits a chromophore it releases electrons that are bright enough to be seen. Common examples of such molecules include ingredients in paint and food coloring.

Practical uses for the technology include almost any …

Barrel Toroid is Largest Superconducting Magnet

Posted in CERN, Magnets, Science by Paul Patterson on December 31st, 2006

The ATLAS DetectorThis is the ATLAS Detector, home of Barrel Toroid - the largest superconducting magnet ever built. The barrel-shaped magnet provides the magnetic field for ATLAS, a particle detector at CERN1’s Large Hadron Collider (LHC).

The Barrel Toroid consists of eight precisely aligned rectangular-shaped superconducting coils measuring 5m wide, 25m long and weighing 100 tonnes. The magnet will be used in ATLAS to bend the paths of charged particles produced in collisions at the Collider.

The goal of ATLAS is to answer questions like: why particles have mass, what is the unknown 96% of the Universe made of, and why Nature prefers matter to antimatter.

The magnet was recently powered up to its nominal operating conditions on the first attempt. Still in development by over 1800 scientists from 165 universities and laboratories, the new particle accelerator is scheduled to turn on and start taking data in …
