  • The aggregation size of short side-chain ionomers can be controlled by increasing the dipropylene glycol content because the hydrophobic backbone main chain becomes more mobile due to its high solvating power.

    “The aggregation size of short side-chain ionomers can be controlled by increasing the dipropylene glycol (DPG) content (the solvent) because the hydrophobic backbone main chain of short side chain ionomers becomes more mobile due to their high solvating power.”

  • Decreased ionomer aggregation leads to a more homogeneous ionomer distribution in the catalyst layer, which can facilitate proton transfer at low relative humidity conditions.

    “Reasonably, the decreased ionomer aggregation leads to a more homogeneous ionomer distribution in the catalyst layer, which can facilitate proton transfer at low relative humidity (RH) conditions [171].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
