Advance hastens practicality of superconductivity

Nobody completely understands superconductors. So fathom how James S. Schilling, Ph.D., led a team that makes the phenomenon work better.

Schilling, a professor of physics in Arts & Sciences at Washington University in St. Louis, collaborated with recent doctoral graduate Takahiro Tomita and scientists at Argonne (Ill.) National Laboratory to determine whether one region in superconductors, called grain boundaries (GB), are oxygen deficient. Such oxygen deficiency impairs supercon

Hydrogen Accumulation

The hydrogen storage devices developed and patented by the scientists of the Academy of Advanced Technologies (Moscow) break all records. These are hydrogen accumulators based on microporous structures, first of all – microspheres and capillaries. Despite seeming elegance and fragility of its “filling”, the device strongly and safely retains a lot of hydrogen in a small volume. A lot of hydrogen means more than 45 grams per litre. By the way, this figure is planned by the US Department of Energ

The “Lark” Is Waiting For The Wind

Electric power is needed in remote regions difficult of access, settlements, expeditions and at timber-felling. Where can it be obtained from? Specially for such occasions, researchers from the Moscow Institute of Heating Engineering have invented a wind turbine, which can be delivered by car in a container or by helicopter, for example, MI-26 at external load. The developers promise that the device would supply energy without interruption. “What about dead calm weather?” – you would ask. In this c

Manchester develops wireless ‘wear and tear’ sensor

Sensors which are able to predict when mechanical parts in machinery and transport will breakdown before they actually do could be introduced by 2010, slashing maintenance costs across the manufacturing, automotive and plant machinery industries.

Scientists at The University of Manchester are to develop a new type of wireless sensor which will be able to remotely monitor mechanical parts and systems. The aim is to produce a sensor which can be seamlessly fitted inside gearboxes,

ETH researchers develop new, ultra-high-speed drive system

Rotary tools will need increasingly high speeds in the future, for example, for drills used in medical technology or spindles used in machine tools. To drive these tools directly and efficiently requires an ultra-high-speed electrical drive system. Today, industrial motors achieve maximum speeds of 250,000 revolutions per minute, but researchers at ETH Zurich have now developed a drive system which achieves speeds of over 500,000 revolutions per minute, generating 100 watts of drive power and is n

The Nanofabrication Laboratory at Chalmers now accessible for European Researchers

One of the most advanced university cleanrooms in the world, the Nanofabrication Laboratory, at the Department of Microtechnology and Nanoscience, MC2, at Chalmers University of Technology, in Göteborg, Sweden, is now offering European Universities and SME:s access, free of charge, to advanced micro- and nanotechnology fabrication resources.

MC2 is the leading Swedish research facility in nanoelectronics and photonics. MC2 has secured a contract with the European Commission to open up the
