Excellent movie on nanotechnology and STM on Athenaweb
In this film we will find out what tools scientists have developed to explore this new reality, opening up an apparently infinite field of research and practical applications.
Initiated and supported by the European Community , AthenaWeb provides a video portal for European scientists and researchers. The ultimate goal is to add value to scientific audiovisual programs produced in Europe and encourage distribution to scientific professionals.

New Wrinkle in the Mystery of High-Tc Superconductors

The latest wrinkle uncovered by Tonica Valla’s group (U.S. Department of Energy’s Brookhaven National Laboratory) concerns a material that is not a superconductor. The material is a special form of a compound made of lanthanum, barium, copper, and oxygen, where there is exactly one barium atom for every eight copper atoms. With less or more barium, the material acts as a high-Tc superconductor (in fact, this was the very first high-Tc superconductor discovered). But at the 1:8 ratio, the material momentarily loses its superconductivity.

Implementing a Quantum Computation by Free Falling
SCIENCE, Volume 311, Issue 5764, February 24 - 2006 Perspectives
|
Quantum computers may become more powerful than conventional computers, especially at solving hard problems. Finding efficient ways to tackle such problems turns out to resemble understanding the path taken by a falling object.

Demonstration of First Superconductor Power Transformer in Chinese Energy Distribution Grid
American Superconductor Corporation , a leading energy technologies company, and China's Institute of Electrical Engineering (IEE) announced that IEE has successfully demonstrated a prototype superconductor-based power transformer for the first time in a power grid in China. The transformer was fabricated by IEE in collaboration with TBEA Industrial Transformer Group, the largest transformer manufacturer in China, utilizing high temperature superconductor (HTS) wire (...) The HTS transformer has operated since November 21, 2005 in a power grid in the city of Changji, Xinjiang Province.
