The method works by solidifying a resin that hardens when exposed to light. The resin is solidified into a three-dimensional grid by placing it in the interference pattern set up by four intersecting ...
The quantum of conductance, G0, is defined by a simple equation: G0=2e2/h, where e is the charge on the electron and h is the Planck constant. The conductance of an individual nanotube is predicted to...
Using citation data from the Institute for Scientific Information in Philadelphia, Katz has found that there is in fact a power-law or “fractal” relationship between the number of citation...
Diodati says he became intrigued by the link between music and physics after thinking about the crescendo in Rossini’s La calunnia è un venticello, an aria from the Barber of Seville. The w...
The DAMA collaboration, which is lead by Rita Bernabei of the University of Rome, will present its results at the Fourth International Symposium on Sources and Detection of Dark Matter/Energy in the U...
The number of transistors on a silicon chip has doubled every 18 months, but many observers believe that semiconductor technology will reach its limit in a decade or so. This has prompted the developm...
The MIT team injected small quantities of air into a highly viscous liquid to stimulate the formation of air bubbles. As the bubbles reached the surface, da Silveira and colleagues punctured them with...
One of the biggest challenges in quantum computation is to built “fault tolerant” logic gates. In the mid-1990s it was shown that this requires the time evolution of a quantum sub-system t...
Light emission from organic materials occurs through two separate processes: fluorescence – the process by which today’s organic semiconductors produce light – and phosphorescence. I...
Previously is was thought that the result might have been due to some inadequacy in the data for the troposphere. However, Dian Gaffen from the US National Oceanic and Atmospheric Administration and c...
