An AI model adapted from image inpainting can reconstruct missing atoms in crystal structures with a reported 97 percent success rate. A crystal structure can appear nearly complete yet still be unusable for computer simulations because some of its atoms are missing. Hydrogen is a frequent source of these gaps, and researchers have now adapted [...]

Researchers observed a hidden state triggered by light forming within 30 femtoseconds. A pulse of light sent a metal-organic framework into a hidden electronic state in just 30 femtoseconds. By watching the transformation almost as it happened, researchers uncovered a fleeting intermediate stage that appears to guide the material into its new state. The work [...]
