Polarization of water molecules at a charged interface: second harmonic studies of the silica/water interface

Abstract

Surface second harmonic generation was used to probe the silica/water interface. At pH values where the silica surface is charged, we found that the water molecules near the interface are polarized by the interfacial electric field and are responsible for the observed second harmonic light. Two types of silanol sites having pKa values of 4.5 and 8.5 were inferred from the data. A promising result of the studies was the development of a new method for obtaining electric potentials at charged liquid interfaces.

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.
