As the clouds clear on computational crystal structure prediction, is the technique ready to empower mainstream materials research? James Mitchell Crow reports ...

Each block represents an atom in a tiny crystal ... In this structure, lead and sulfur atoms should arrange themselves in a very ordered lattice, much like alternating red and blue Lego blocks.

By tweaking the crystal layers of blue-light-producing wafers and the structure of waveguides ... were partly based on results from a New Energy and Industrial Technology Development Organization ...
