As materials used in key equipment, such as hydrogenation reactors, are subjected simultaneously to the action of hydrogen and high temperature, studies on the material property degradation and remaining life prediction are of very important engineering and academic significance.

Hydrogen embrittlement is a form of environmentally assisted failure which is caused by the action of hydrogen often in combination with residual or applied stress resulting in the reduction of the load bearing capacity of a component.
As an inter-assay standard the action of hydrogen peroxide was tested in every test plate.
In the first region (low pressures), the N, δ and ψ abruptly drops, and in the second, the negative action of hydrogen becomes stable or decrease negligibility.
Adjacent micelles may be connected with each other through the action of hydrogen bonds and coordinative bonds to form a spatial network structure and to wrap a lot of liquid oil in it (Zhu et al. 2011, 2012).
They exert the protective action via hydrogen atom transfer (HAT) and/or sequential electron proton transfer (SEPT) mechanisms which make phenolic –OH moiety be oxidized to stable semi-quinone form.
They can also be obtained from animal bones due to thermal treatment and as a result of the action of hydrogen peroxide in order to remove organic fractions from bones.
The hydride is obtained by direct action of hydrogen on the metal at 250 °C, and the nitride is a product of ammonia and protactinium tetrachloride or pentachloride.
According to Ponnudurai et al. [ 53], this biological effect may result from a secondary action of hydrogen peroxide produced during the oxidation reaction of the substrate.
Furthermore, in vitro co-culture experiments indicate that S. pneumoniae can inhibit H. influenzae through the action of hydrogen peroxide (29 ).
