The phrase "are more reactive at" is correct and usable in written English.
It can be used when discussing the reactivity of substances or elements in a specific context, such as temperature or concentration.
Example: "Sodium and potassium are more reactive at higher temperatures, leading to more vigorous reactions."
Alternatives: "exhibit greater reactivity at" or "show increased reactivity at".
That is, the dealloyed samples are more reactive at lower overpotentials but less reactive at higher overpotentials for HER measurements.
This combination causes the crossing of the HER curves in Figure 6, where the dealloyed samples are more reactive at lower overpotentials and less reactive at higher overpotentials.
It is along the edges where marked differences arise: graphene edges are more reactive at the point that they immediately prompt water splitting.
Metals with higher standard electrode potentials are more reactive, as indicated qualitatively by the arrow at the top of the graph.
The result also showed that silica fume included in the UHPC matrix was more reactive at early ages, which was completely in agreement with reduction of calcium hydroxide (CH) content at the same hydration period.
Human beings are more reactive today than at any other point in our history, including when we were primitive hunter-gatherers.
A study conducted at the Lyon Neuroscience Research Center in France supported this theory, concluding that "high dream recallers are more reactive to environmental stimuli [during sleep], awaken more during sleep, and thus better encode dreams in memory than low dream recallers".
The game becomes more unstructured, which means you've got to be more reactive to who's at the breakdown and you could see at times this did not come automatically for some of the players.
This is due to the fact that Ti is more reactive with O2 (-888 kJ/mole at 300 K [35]), which results in formation of TiOxNy layer at the GdOx/TiN interface.
Both of the iron oxides were found to be efficient in incorporating Cd into the CdFe2O4 spinel structure, but Fe3O4 was more reactive in the Cd incorporated at low temperatures.
