They moreover slow down micrograin boundary migration and impede reactions between dislocations and subgrain boundaries.

In contrast, the higher values for higher reaction temperature may indicate the involvement of blocking oxides layer that impedes reaction occurring within the interior of the aluminum particles.

A 4-methyl group greatly impedes reaction, presumably because of steric interactions, so that extensive microwave heating in acetonitrile was required to prepare 2-methyl-8-nitrophenanthridinium 23 k.

However, placing an electron-donating methoxy group para to the fluoride significantly impeded reaction even when the 8-nitro group was present, so that phenanthridinium 23 e was produced in lower yield under all conditions (the best yield was obtained under the original solventless conditions with extended heating).

One of many possible influences, atmospheric scientists say, is an increase in haze, which could block ultraviolet light and impede the reaction that creates the molecules.

This could impede the reaction efficacy of tPA to the particle surface.

This oscillating structure might cause the translational excitation to impede the reaction.
