All-Silicon Clock Oscillator Technology Offers Viable, Low Cost Alternative to Quartz and SiMEMS Oscillators Cairo, Egypt (PRWEB) April 25, 2011 Si-Ware Systems (SWS) today announced a novel Self Compensating Oscillator (SCO) technology, which produces an all-silicon oscillator that can achieve an overall frequency stability better than 100ppm over a temperature range of -20ºC to 70ºC. The SCO is an all-silicon oscillator that does not require an external frequency reference for...

University of Oregon physicists have successfully landed a one-two punch on a tiny glass sphere, refrigerating it in liquid helium and then dosing its perimeter with a laser beam, to bring its naturally occurring mechanical vibrations to a near standstill.The findings, published in Nature Physics, could boost advances in information processing that exploits special quantum properties and in precision-measurements for nanotechnology. The ability to freeze mechanical fluctuations, or...

More than one nanostring to their bowThese days, chemical analysts are expected to track down even single molecules. To do this highly sensitive detective work, nano researchers have developed minute strings that resonate in characteristic fashion. If a molecule docks onto one of the strings, then it becomes heavier, and its oscillations become measurably slower. Until recently, however, such "nano-electromechanical systems", or NEMS, have been short of practical applications. Physicists at...

Caesium fountains are more accurate than "normal" atomic caesium clocks, because in fountains the caesium atoms are cooled down with the aid of laser beams and come ever slower - from a rapid velocity at room temperature to a slow "creep pace" of a few centimetres per second at a temperature close to the absolute zero point. Thus, the atoms remain together for a longer time so that the physicists have considerably more time to measure the decisive property of the caesium atoms which is...
