The rhombic dodecahedron crystals were found to degrade faster during operation, possibly due to self-oxidation. In contrast, the cube-shaped crystals—though less reactive—were more robust ...

The researchers found that the rhombic dodecahedron version, exposing the {110} surface, delivered the strongest catalytic activity for ORR, while the cube was most stable over time. Schematic oxygen ...

The crystals were in the form of isotropic rhombic dodecahedra of average diameter of only 0·01 mm. Consequently, no attempt was made to take single crystal photographs.

Researchers know this protein’s structure and that it can crystallize into a diamondlike rhombic form or a rectangular prismatic form. Through their cryo-EM studies, Sleutel’s team learned ...
