Innovative method enables new view into Earth's interior

An innovative X-ray method enables new high-pressure investigations of samples under deep mantle conditions. The technique, which was developed by a team led by Georg Spiekermann from DESY, the German Research Centre for ...

New electron glasses sharpen our view of atomic-scale features

What if we could make a powerful scientific tool even better? Atom probe tomography (APT) is a powerful way of measuring interfaces on a scale comparable to the distance between atoms in solids. It also has a chemical sensitivity ...

Making silicon-germanium core fibers a reality

Glass fibres do everything from connecting us to the internet to enabling keyhole surgery by delivering light through medical devices such as endoscopes. But as versatile as today's fiber optics are, scientists around the ...

Researchers produce industry's first 7nm node test chips

An alliance led by IBM Research today announced that it has produced the semiconductor industry's first 7nm (nanometer) node test chips with functioning transistors. The breakthrough, accomplished in partnership with GLOBALFOUNDRIES ...

With new design, bulk semiconductor proves it can take the heat

The intense interest in harvesting energy from heat sources has led to a renewed push to discover materials that can more efficiently convert heat into electricity. Some researchers are finding those gains by re-designing ...
