Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...

Detailed architecture of different copper nanoclusters. All the nanoclusters have identical numbers of copper atoms, thiolate ligands and hydrides. The alteration is visible only in PPh₃ ligand ...
