Part 5/9:
Grignia focused on the palladium-coated nickel mesh, showing that the palladium treatment resulted in relatively uniform nanostructured deposits across the surface, while also highlighting variations due to potentially lower palladium content in more physically damaged areas due to handling. This indicated that the distribution of palladium interaction with nickel could influence reaction outcomes, specifically regarding the generation of excess heat.
Using characteristics derived from previous studies and SEM observations, Grignia estimated the palladium coating thickness to be between 250 to 400 nanometers. This estimation was significant, as it suggested the importance of thickness in relation to the potential reactivity of the mesh when loaded with deuterium.
