With its new Sirius Modular System for industrial controls, Siemens has succeeded not only in cutting down on the amount of wiring work but also in reducing space requirement in the control panel. At ...
Machine Engineering |Robert Whittlesey and John Dabiri of the California Institute of Technology have developed a potentially more efficient wind farm design that maximizes the efficiency of land usage. They based their a...
Physics and Astronomy |The researchers will present their work next week at the 62nd Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics will take place from November 22-24 at the Minneap...
Medical Engineering |But new research from the University of Washington shows this is not likely to be true. Algae provide a much richer diet for fish and other aquatic life, according to research published this week in t...
Ecology, The Environment and Conservation |"The predictive capabilities of today's state-of-the-art models in urban areas need to be improved, validated and tested," says Grinstein. "Work in this area has been limited prima...
Physics and Astronomy |More than 60 years ago, oceanographers predicted that the effect of swimming animals could be profound. Accounting for this effort has proven difficult, though, so it has not entered into today's...
Physics and Astronomy |They will present their concept later this month at the 62nd Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics will take place from November 22-24 at the Minneapo...
Physics and Astronomy |Battery-powered cell phones serve as hand-held computers and more these days. We run power-hungry applications while we depend on the phones to be available in emergencies. "Today, we exp...
Power and Electrical Engineering |Researchers at the University of Illinois have developed a technique for fabricating three-dimensional, single-crystalline silicon structures from thin films by coupling photolithography and a self-fo...
Physics and Astronomy |A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground car...
Physics and Astronomy |Now scientists from the UCLA Department of Neurology have confirmed that blindness causes structural changes in the brain, indicating that the brain may reorganize itself functionally in order to adap...
Studies and Analyses |C&EN Senior Editor Alexander Tullo explains that rolling resistance — the friction that tires encounter when rolling — are a major factor in a vehicle’s fuel economy. It can determine up to 20 percent...
Ecology, The Environment and Conservation |“Tsunamis can neither be prevented nor precisely predicted yet,” says site initiator Dr. Jian Lin, a WHOI geologist actively involved in tsunami research and a member of a U.S. national committee on t...
Earth Sciences |Physicians currently insert camera-equipped endoscopes into patients to hunt visible abnormalities, such as tumors, in the gastrointestinal tract and internal organs. Huikai Xie, an associate professo...
Medical Engineering |The researchers have demonstrated the ability to electrically manipulate, at gigahertz rates, the quantum states of electrons trapped on individual defects in diamond crystals. This could aid in the d...
