Oerlikon Leybold Vacuum Obtains ATEX Certificate for Steel Degassing Vacuum Systems
2014-06-30 06:00:00| Industrial Newsroom - All News for Today
In recent decades, the demand for higher-quality, refined steels has increased steadily. At the same time, steel plants operate under the increasing pressure to design their processes more energy-efficient and reduce CO2 emissions drastically. Higher-grade steels which are demanded e.g. by the automotive or aerospace industry require further treatment in the so-called secondary metallurgical processes, which are often carried out under vacuum. Degassing, especially those with oxygen ...This story is related to the following:Green & CleanSearch for suppliers of: Degassers

The vacuum tube strikes back: NASAs tiny 460GHz vacuum transistor that could one day replace silicon FETs
2014-06-24 14:12:20| Extremetech
Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified light bulbs. This is why early computers like the ENIAC weighed more than 27 tons and consumed more power than a small town. Later, obviously, vacuum tubes would be replaced by probably the greatest invention of all time -- the solid-state transistor -- which would allow for the creation of smaller, faster, cheaper, and more reliable computers. Fast forward to 2014, though, and the humble CMOS field-effect transistor (FET) is starting to show its age. We've pretty much hit the limit on shrinking silicon transistors any further, and they can't operate at speeds much faster than a few gigahertz. Which is why NASA's Ames Research Center is going back to the future with its new vacuum transistor -- a nanometer-scale vacuum tube that, in early testing, has reached speeds of up to 460GHz.
