Study Finds More Efficient Means Of Creating, Arranging Carbon Nanofibers

Carbon nanofibers hold promise for technologies ranging from medical imaging devices to precise scientific measurement tools, but the time and expense associated with uniformly creating nanofibers of the correct size has been an obstacle – until now. A new study from North Carolina State University demonstrates an improved method for creating carbon nanofibers ofspecific…

核:Some Media Coverage Into Perspective

Note: This is a guest piece written by Steve Skutnik, a Ph.D. candidate in nuclear engineering at NC State. Among other things, Skutnik is a regular contributor to the nuclear engineering blog The Neutron Economy, where a version of this post originally ran. In times of crisis, mainstream media can make mistakes – particularly whenthe…

Fire It Up

The basketball is in your hands, the score is tied and time's running out. You're about 10 feet away from the basket on the right side of the court, just outside the free-throw lane. Before the clock hits 0:00, check out new research from NC State engineers that shows whether a direct shot or a bank shot has a better chance of scoring your team a postgame victorycelebration.

New Technique Boosts High-Power Potential For Gallium Nitride Electronics

Gallium nitride (GaN) material holds promise for emerging high-power devices that are more energy efficient than existing technologies – but these GaN devices traditionally break down when exposed to high voltages. Now researchers at North Carolina State University have solved the problem, introducing a buffer that allows the GaN devices to handle 10 timesgreater…

Raw Power: Buffers Boost GaN Device Capacity

Gallium nitride (GaN) devices are supposed to be the next big thing in power electronics (think electric cars or smart grid). Or they would be, if they didn’t keep breaking when exposed to high voltages. New research may have solved that problem by implanting buffers made of argon that allow the devices to handleten…

Hacked? Go Back In Time To Protect Yourself

If a hacker gets control of your computer’s operating system (OS), you’re hosed. The OS basically gives them control over everything. But researchers have now come up with a nifty combo of hardware and software that effectively lets you go back in time if you’re hacked – re-setting the OS to its happier, pre-attackcondition…

Into The Void: Boosting LED Energy Efficiency

LEDs are already vaunted as an energy-efficient technology for lighting, but new research shows that their efficiency can be increased by a factor of two. A paper describing the work shows that the secret is to decrease the number of defects in the gallium nitride (GaN) films used to create LEDs by incorporating cleverly把…

Hardware, Software Advances Help Protect Operating Systems From Attack

The operating system (OS) is the backbone of your computer. If the OS is compromised, attackers can take over your computer – or crash it. Now researchers at North Carolina State University have developed an efficient system that utilizes hardware and software to restore an OS if it isattacked.
