Metal oxide dopants, such as titanium and chromium oxides, have garnered considerable attention for their potential to increase grain size (≥ 30 µm) in UO2 fuel, purportedly enhancing fission gas ...

Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1.2 × 10 18 (1,200,000,000,000,000,000) ions. The lattice arrangement continues in three dimensions.

This research is published in Science, titled "Grain boundaries are Brownian ratchets." Crystals are characterized by ...
