Water could hold answer to graphene nanoelectronics
11 May, 2011
Researchers at Rensselaer Polytechnic Institute in New York have developed a method for using water to tune the band gap of the nanomaterial graphene, opening the door to new graphene-based transistors and nanoelectronics.
Standby comfortable but energy inefficient
11 May, 2011 by Reinhard Zimmermann
The former ‘green’ theme of energy efficiency has become a household issue in an energy-conscious society. The old filament bulb disappears step by step, and washing machines and dishwashers have become unsaleable without energy-saving programs. But most industrialised societies waste energy on a massive scale by indulging in comfortable ‘standby mode’ in domestic electronics.
Data bus concepts and considerations
11 May, 2011 | Supplied by: Unitronix Pty Ltd
The digital data bus MIL-STD-1553B was designed in the early 1970s to replace analog point-to-point wire bundles between electronic instruments. The latest version of the serial local area network (LAN) for military avionics known as MIL-STD-1553B was issued in 1978. Since then, various notices have been published to update the standard and after 30 years the data bus continues to be the most popular militarised network.
