While in most theoretical studies the solution is treated as a homogeneous structureless dielectric medium, recent experimental studies concluded that, for a bathing solution composed of two solvents (binary mixture), the osmotic pressure between charged macromolecules is affected by the binary solvent composition. By adding local solvent composition terms to the free energy, we obtain a general expression for the osmotic pressure, in planar geometry and","authors_text":"Dan Ben-Yaakov, Daniel Harries, David Andelman, Rudi Podgornik","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2009-01-15T12:59:32Z","title":"Ions in mixed dielectric solvents: density profiles and osmotic pressure between charged interfaces"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0901.2254","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:85876381c303d4e702ba89fc1ee81bd900fdb7a943c08746cf22625f098b1301","target":"record","created_at":"2026-05-18T02:53:54Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"bb4cc9366976664426e8a8b50a0e2d86771730b94771b3f8c4e701af5b41af0d","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2009-01-15T12:59:32Z","title_canon_sha256":"ffa49bef39b673e87fc62e2f5299325c1419d8e6197653e7aac9d7dab901d5b6"},"schema_version":"1.0","source":{"id":"0901.2254","kind":"arxiv","version":2}},"canonical_sha256":"96159c180647f3b852c0f9720904361e59380999f2fa62a34a58028f8e2ca157","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"96159c180647f3b852c0f9720904361e59380999f2fa62a34a58028f8e2ca157","first_computed_at":"2026-05-18T02:53:54.610185Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:53:54.610185Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wpzsFBVzUUob92xHvCa9WIyDdjRx5YavOZX9wWnLtNuQki3942+Mig3GGa95xwp3YIda3cllpWQyX5Vqg2c1AA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:53:54.611199Z","signed_message":"canonical_sha256_bytes"},"source_id":"0901.2254","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:85876381c303d4e702ba89fc1ee81bd900fdb7a943c08746cf22625f098b1301","sha256:761c33c071a0a60c02874a6bdb232ca06ec43272b0d009a39fa702979d54691a"],"state_sha256":"03c4afaa1c50bf91f82391f7b731919d486307260de7c051a57dbc444d21a370"}
