Novel nano-mechanics: Mechanical resonators are extensively used in high-tech industry, to mark time in electronic components, and to stabilize radio transmissions Most mechanical resonators damp (slow down) in a well-understood linear manner, but ground-breaking work by Prof. Adrian Bachtold and his research group at the Catalan Institute of Nanotechnology has shown that resonators formed from nanoscale graphene and carbon nanotubes exhibit nonlinear damping, opening up exciting...

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...

'Quantum-mechanics' solve a very classical problem: From the wooden bars in a xylophone or the head of a drum, to the strings and sound box of a guitar or violin, musical instruments are the most familiar examples of mechanical resonators. The actual mechanical vibrations of these instruments create acoustic waves that we hear as sound. The purity of the emitted tone is intimately related to the decay of the vibration amplitude, that is, the mechanical losses of the system. A figure of merit...

With NSF support, Elena Semouchkina and colleagues are experimenting with ways of using magnetic resonance to capture rays of visible light and route them around objects, rendering those objects invisible to the human eye By Marlene Cimons, National Science Foundation In 1897, H.G. Wells created a fictional scientist who became invisible by changing his refractive index to that of air, so that his body could not absorb or reflect light. More recently, Harry Potter disappeared from sight after...

Inspired by the popular confidence trick known as "shell game," researchers at UC Santa Barbara have demonstrated the ability to hide and shuffle "quantum-mechanical peas" "“"“ microwave single photons "“"“ under and between three microwave resonators, or "quantized shells." In a paper published in the Jan. 30 issue of the journal Nature Physics, UCSB researchers show the first demonstration of the coherent control of a multi-resonator architecture. This topic has been...

An invisibility cloak made of glass From Tolkien's ring of power in The Lord of the Rings to Star Trek's Romulans, who could make their warships disappear from view, from Harry Potter's magical cloak to the garment that makes players vanish in the video game classic "Dungeons and Dragons, the power to turn someone or something invisible fascinates mankind. But who ever thought that a scientist at Michigan Technological University would be serious about building a working invisibility cloak?...

Silicon microring resonator could help advance nanomanipulation To trap and hold tiny microparticles, engineers at Harvard have "put a ring on it," using a silicon-based circular resonator to confine particles stably for up to several minutes. The advance, published in the June 14 issue of Nano Letters, could one day lead to the ability to direct, deliver, and store nanoparticles and biomolecules on all-optical chips. "We demonstrated the power of what we call resonant cavity trapping, where...

Nanotechnology has already made it to the shelves of your local pharmacy and grocery: nanoparticles are found in anti-odor socks, makeup, makeup remover, sunscreen, anti-graffiti paint, home pregnancy tests, plastic beer bottles, anti-bacterial doorknobs, plastic bags for storing vegetables, and more than 800 other products. How safe are these products and the flood of new ones about to spill out of labs across the world? A group of researchers at Washington University is devising instruments...

Word of the Day
  • Remarkable; prodigious.
  • Audacious; gutsy.
  • Completely; extremely.
  • Audaciously; boldly.
  • Impressively great in size; enormous; extraordinary.
This word is probably from the dialectal 'boldacious,' a blend of 'bold' and 'audacious.'
