      • 1914, Alexander Graham Clark, Text Book on Motor Car Engineering - Volume 1, page 68:

        Unlike the plutonium case one more barrier for potential proliferation of ²³³U can be created by denaturising it by mixing it with the non-fissile isotope ²³⁸U (in practice with depleted uranium) to create 'reactor grade' but not a 'weapon grade' ²³³U/²³⁸U mixture not adherent to chemical separation.

In modern usage, denature is generally used in preference to denaturise except when used to mean taking away a natural characteristic.
