We attach an electrode to a dielectric film bearing silanol or carboxyl groups with an areal density $\\Gamma_0$, where the degree of dissociation $\\alpha$ is determined by the proton density in water close to the film. We show how $\\alpha$ depends on the density $n_0$ of NaOH in water and the surface charge density $\\sigma_m$ on the electrode. For $\\sigma_m>0$, the protons are expelled away from the film, leading to an increase in $\\alpha$. In particular, in the range $0<\\sigma_m<e\\Gamma_0$, self-regulation occurs "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1608.04462","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
