Cryogenic microcalorimetry: New tool for nuclear dating

The moment nuclear material is produced, processed or purified, it sets off a hidden countdown, marked by the half-life of its radioactive atoms as they begin to decay. For scientists tracking the origins of these substances, ...

AI creates quasi-atoms: A new approach to materials study

Understanding how a crack grows in metal requires simultaneously calculating the behavior of hundreds of billions of atoms: At the crack tip, where atomic bonds break, and in the surrounding volume of material, where the ...

AI turns electron microscopy into materials insights in minutes

An electron microscopy image can capture atoms arranged in a crystal lattice or defects threading through a semiconductor material, but turning that image into materials insight can take weeks of careful analysis. Now, an ...
