What do you get when you subject Nitrogen to pressures 2.4 million times the atmospheric pressure at sea level? The answer is a new form of Nitrogen that is a semiconducting solid. For the first time, scientists at Carnegie Institute at Washington made electric measurements on the condensed gas. This new dense form of Nitrogen stores energy, which they say makes it viable for semiconducting material. The material remains stable after the pressure is removed. The institute's work is partially funded by the National Science Foundation's Division of Materials Research. The findings also confirm theories about superconductivity properties in other elements, such as Hydrogen. For more information, contact the institute's team leader Russell Hemley at (202) 478-8951.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
