Plasmonic hydrogen sensors with ppb limit of detection!

Read our latest work on plasmonic hydrogen sensors published in Nature Communications on the topic of pushing the limit of detection to the parts per billion range by inverse design of Pd arrays that feature surface lattice resonances. The work is a collaboration with the groups of Prof. Jaime Gómes-Rivas at TU Eindhoven and Prof. Andrea Baldi at VU Amsterdam. Read the work here: . DOI:10.1038/s41467-022-33466-8

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.
