Researchers at Rensselaer Polytechnic Institute have discovered the origins of nanorod diameter, demonstrating that the competition and collaboration among…
Development of the device brings researchers a big step closer to higher speed electronics and higher performance electrical and optical integrated circuits.The mixing device accepts two electrical inputs and produces an optical signal that was measured at frequencies of up to 22.7 gigahertz. The frequency range was limited by the bandwidth of the detector employed in the measurements, not by the transistor device.“…
The picture that emerges from these first-ever simultaneous observations with optical, X-ray and new-generation gamma-ray telescopes is much more complex than…
Lawrence Livermore National Laboratory scientists have for the first time converted the highest frequency sounds into light by reversing a process that…
The Gregor Solar Telescope saw sunlight for the first time at 14:55 UT on Thursday, March 12, 2009. This picture shows the image of the Sun on the field stop…
Three members of the faculty at Stevens Institute of Technology recently collaborated on a paper focusing on free-space optical communication, which appears in…
“We found more support for the idea that biological molecules, like amino acids, created in space and brought to Earth by meteorite impacts help explain why…
Sometimes objects in the sky that appear strange, or different from normal, have a story to tell and prove scientifically very rewarding. This was the idea…
In this view, the giant orange moon Titan casts a large shadow onto Saturn's north polar hood. Below Titan, near the ring plane and to the left is the moon…
The two states each have unique properties that could be used to develop new silicon-based materials. Furthermore, the methods developed can be applied to gain…
Single oxygen atoms dancing on a metal oxide slab, glowing brighter here and dimmer there, have helped chemists better understand how water splits into oxygen…
“Certain classes of explosives have unique thermal characteristics that help to identify explosive vapors in presence of other vapors,” says Thomas Thundat, a…
Experimental and theoretical efforts were combined in a synergistic approach and the results, published this week in the ASAP section of the journal Nano…
Shock waves are a well tested phenomenon on a large scale, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and their…
An international team of physicists from the United States and China this week offered a new theory to both explain and predict the complex quantum behavior of…
NASA's Hubble Space Telescope has uncovered a strong new line of evidence that galaxies are embedded in halos of dark matter.Peering into the tumultuous heart…
