Oil Production Standstill, Pipeline Repair in the Gulf
With the nation still feeling the effects of the recent hurricanes, Dr. Shari Dunn-Norman, associate professor of geological and petroleum engineering in the geological sciences and engineering department at the University of Missouri-Rolla, can offer an expert insight into the oil production standstill due to platform and pipeline repair taking place in the Gulf of Mexico.
“The problem is that the hurricanes hit major deepwater production platforms and pipelines that combine flow from mult
Research on "Holes" May Unearth Causes of Superconductivity
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have uncovered another possible clue to the causes of high-temperature superconductivity, a phenomenon in which the electrical resistance of a material disappears below a certain temperature. In a superconducting compound, they found evidence of a rarely seen arrangement of “holes” – locations where electrons are absent. The results appear in the October 28, 2004, issue of Nature.
The researchers wer
Watts from wastewater: New device produces power while treating sewage
A new technology is being developed that can turn raw sewage into raw power. The device, called a microbial fuel cell, not only treats wastewater, but also provides a clean energy source with the potential for enormous financial savings, according to scientists at Pennsylvania State University.
Although power output is still relatively low, they say the technology is improving rapidly and eventually could be used to run a small wastewater treatment plant, which would be especiall
UC Irvine scientists develop world’s longest electrically conducting nanotubes
Breakthrough discovery is 10 times longer than previous current-carrying nanotubes, paves way for supercomputer and health care applications
UC Irvine today announced that scientists at The Henry Samueli School of Engineering have synthesized the world’s longest electrically conducting nanotubes. These 0.4 cm nanotubes are 10 times longer than previously created electrically conducting nanotubes. The breakthrough discovery may lead to the development of extremely strong, light
A Nanowire with a Surprise
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
NASA experiment celebrates 20 years in orbit
From volcanic eruptions to ozone holes, a NASA instrument that monitors Earth’s upper atmosphere marks twenty years in orbit.
The Stratospheric Aerosol and Gas Experiment II (SAGE II) instrument was deployed October 5, 1984, from the Space Shuttle Challenger aboard the Earth Radiation Budget Satellite (ERBS.) Originally scheduled for a two-year mission, SAGE II continues to give scientists a wealth of data on the chemistry and motions of the upper troposphere and stratospher
