The fast ignition concept has been conceived as an alternative to other approaches for nuclear fusion energy. In the fast ignitor scenario a high-energy…
When intense laser light interacts with electrons in nanoparticles that consist of many million individual atoms, these electrons can be released and strongly…
Researchers at Rensselaer Polytechnic Institute have developed a new method for manufacturing green-colored LEDs with greatly enhanced light output.The…
Costa Rica was once regarded as the poorest of all the colonies of the Spanish Empire, sadly deficient in the silver and gold so coveted by conquistadors. As…
Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan…
The researchers found a way to make an “optical battery,” said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science,…
“Identifying the root cause of the problem is an indispensable first step toward devising solutions,” says Chris Van de Walle, a professor in the Materials…
By harnessing the unique properties of polarized light, Rockefeller scientists have now developed a new technique that can help deduce the orientation of…
This greatly enhances the amount of data that can be stored in a magnetic storage device and provides a method to reach beyond a wall of physical limits that…
Invisibility cloaks are seemingly futuristic devices capable of concealing very small objects by bending and channeling light around them. Until now, however,…
A University of Pittsburgh-led team has created a single-electron transistor that provides a building block for new, more powerful computer memories, advanced…
With its promise of superfast computers and ultrapowerful optical microscopes among the many possibilities, plasmonics has become one of the hottest fields in…
The von Zeipel law, named for its creator, Swedish astronomer Edvard Hugo von Zeipel, has been used for the better part of a century to predict the difference…
Just in time for the 100th anniversary to commemorate the discovery of superconductivity by the Dutch physicist Heike Kamerlingh Onnes on April 8, 1911,…
To diversify the applications of superconductors that currently operate at chilly temperatures below 135 kelvin (K), scientists are searching for new classes…
Back in 2008, the solar cycle plunged into the deepest minimum in nearly a century. Sunspots all but vanished, solar flares subsided, and the sun was eerily…
