New research examines corrosion on atomic level

When water vapor meets metal, the resulting corrosion can lead to mechanical problems that harm a machine's performance. Through a process called passivation, it also can form a thin inert layer that acts as a barrier against ...

Protecting biocatalysts from oxygen

Certain enzymes from bacteria and algae can produce molecular hydrogen from protons and electrons—an energy carrier on which many hopes are riding. All they need for this purpose is light energy. The major obstacle to their ...

Using the power of symmetry for new quantum technologies

By taking advantage of nature's own inherent symmetry, researchers at Chalmers University of Technology in Sweden have found a way to control and communicate with the dark state of atoms. This finding opens another door toward ...

Unique ferroelectric microstructure revealed for first time

A team of researchers have observed and reported for the first time the unique microstructure of a novel ferroelectric material, enabling the development of lead-free piezoelectric materials for electronics, sensors, and ...

A new look at disordered carbon

When carbon atoms stack into a perfectly repeating three-dimensional crystal, they can form precious diamonds. Arranged another way, in repetitive flat sheets, carbon makes the shiny gray graphite found in pencils. But there ...

Signature approach reveals prized property in nanoscopic material

It took a nanoscale construction project on par with the much larger ones peppering Nebraska highways, but physicist Xia Hong is now directing the haphazard traffic of electrons well enough to analyze it—and, down the road, ...
