Sentence examples for hydrogen availability from inspiring English sources

These anomalies are explained by the hydrogen availability at the crack tip as a function of the test parameters.

The hydrogen availability located in alkyl substituents plays an important role in determining oxidation reactivity, requiring less activation energy for abstraction through the (1,5) H-shift isomerization.
