Heat from Earth’s core could be underlying force in plate tectonics

For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the … Continue reading

Metal Foam Protects From Fire and Heat Twice as Well as Plain Metal

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. … Continue reading

Researchers ‘Nanoweld’ by Applying Light to Aligned Nanorods in Solid Materials

Researchers from North Carolina State University have developed a way to melt or “weld” specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to … Continue reading

Force is the Key to Granular State-Shifting

Ever wonder why sand can both run through an hourglass like a liquid and be solid enough to support buildings? It’s because granular materials – like sand or dirt – can change their behavior, or state. Researchers from North Carolina … Continue reading
