Metal foam handles heat better than steel

01-Apr-2016

A new study from North Carolina State University researchers finds that novel light-weight composite metal foams (CMFs) are significantly more effective at insulating against high heat than the conventional base metals and alloys that they're made of, such as steel. The finding means the CMF is ...

Magnetic nanoparticle chains offer new technique for controlling soft robots

22-Dec-2015

esearchers from North Carolina State University have developed a technique for using chains of magnetic nanoparticles to manipulate elastic polymers in three dimensions, which could be used to remotely control new "soft robots." The ability to control the motion of soft robots, coupled with their ...

New metamaterial manipulates sound to improve acoustic imaging

18-Dec-2015

Researchers from North Carolina State University and Duke University have developed a metamaterial made of paper and aluminum that can manipulate acoustic waves to more than double the resolution of acoustic imaging, focus acoustic waves, and control the angles at which sound passes through the ...

Diamonds at room temperature

New phase of carbon

02-Dec-2015

Researchers from North Carolina State University have discovered a new phase of solid carbon, called Q-carbon, which is distinct from the known phases of graphite and diamond. They have also developed a technique for using Q-carbon to make diamond-related structures at room temperature and at ...

Dielectric film has refractive index close to air

13-Oct-2015

Researchers from North Carolina State University have developed a dielectric film that has optical and electrical properties similar to air, but is strong enough to be incorporated into electronic and photonic devices - making them both more efficient and more mechanically stable. At issue is ...

Researchers aim to develop new techniques for creating high-temperature alloys

09-Oct-2015

North Carolina State University is taking the lead in a new initiative aimed at addressing fundamental scientific questions that could lead to the development of so-called "entropy-stabilized alloys" that can withstand extremely high temperatures. The initiative includes Duke University, the ...

First entropy-stabilized complex oxide alloys

30-Sep-2015

Researchers from North Carolina State University have created the first entropy-stabilized alloy that incorporates oxides - and demonstrated conclusively that the crystalline structure of the material can be determined by disorder at the atomic scale rather than chemical bonding. "High entropy ...

Sandcastles inspire new nanoparticle binding technique

11-Aug-2015

If you want to form very flexible chains of nanoparticles in liquid in order to build tiny robots with flexible joints or make magnetically self-healing gels, you need to revert to childhood and think about sandcastles. Researchers from North Carolina State University and the University of North ...
