  • The maximum theoretical pH sensitivity of the SiO2 gate dielectric at this pH range is 47-50 mV dec−1.

    “where the maximum theoretical value for the pH sensitivity of the SiO 2 gate dielectric at this range of pH is 47-50 mV dec À1 .22”

    From Specific and label-free femtomolar biomarker detection with an electrostatically formed nanowire biosensor (2013) · cites this paper as [22]

    Section 3 (page unavailable) calculates theoretical pH sensitivities for SiO₂ and other oxides, so the source supports the subject of the claim. It does not give a 47–50 mV per pH unit maximum for SiO₂ in the specified range; the theoretical maximum it states is 59.2 mV per pH unit, without identifying that as the SiO₂-specific value in that range.

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.
