Hydrogen migration in monoclinic ZrO₂ and the effects of defects and dopants assessed by first-principles calculations
Zirconium-based alloys, which have been employed as cladding materials in nuclear industry, pick up hydrogen during service because of corrosion in water. This is one of the degradation processes that challenge the safe operation of nuclear reactors. Composition of commercial zirconium-based alloys …

The high temperature structural evolution of hafnia
The transformations of HfO2 are often described as analogous with the transformations in ZrO2 because of the similar crystal structures; however the phase transformations in HfO2 occur at higher temperatures. Even though this phase transformation has been extensively studied in ZrO2 , the …
