When found in nature, sodium iridium oxide crystals form honeycomb-like plates. But the crystals we see here have rounded edges and holes. We’re not sure why. It may be that fast-track growth in the lab (where it takes days rather than millennia for a crystal to form) allows the individual hexagonal cells to stack with a slight rotational offset, resulting in these curious shapes. If you were to visit our lab this is exactly what you would see looking through a Scanning Electron Microscope. Can you find Snoopy?
