Check out our latest work on hydrogen sorption kinetics and compensation effects in Nature Communications!

In this work, we demonstrate using single particle experiments that hydrogen sorption induces significant grain growth in polycrystalline Pd nanoparticles and that this grain growth constitutes the physical origin of the also observed compensation effect between kinetic parameters. Furthermore, the grain growth considerably slows sorption kinetics, which establishes grain engineering as a new parameter for the design of ultrafast hydrogen sensors.
