Nano mechanical oscillator makes big wave
News & Analysis  
2/21/2005   Post a comment
A 1.5-GHz silicon "comb" that is said to be the world's fastest nanoscale electromechanical system (NEMS) is nevertheless huge on the quantum scale: The oscillation of its teeth exhibit the world's biggest quantum motion. According to the research project team, headed by Boston University professor Pritiraj Mohanty, the teeth of the comb exhibit quantum-mechanical motion by jumping between two discrete positions without passing through the physical space between them.

Semiconductor aerogels advance sensors
Design How-To  
2/7/2005   Post a comment
Semiconducting aerogels have recently been demonstrated that cast quantum dots into a sparse, crystalline-like matrix with more space than substance. Such porous materials could enable supersensitive sensors and superefficient plastic photovoltaics, said the Wayne State University research team pursuing the project.
