The defects are modeled by a smooth function and the contact angle hysteresis is explained using a tangent line solution. When the liquid micro-meniscus touches both sides of the defect simultaneously, depinning of the contact line occurs. The defects are fabricated using a photoresist and experimental results confirm the model. An important point is that the model is scale-independent, i.e. the contact angle hysteresis is dependent on the aspect ratio of the function, not on its absolut","authors_text":"Damien Debuisson, Renaud Dufour, Steve Arscott, Vincent Senez","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2011-01-05T09:22:34Z","title":"Wetting on smooth micropatterned defects"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1101.0915","kind":"arxiv","version":1},"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":"sha256:78714188334412117098e203f8e66e7cc7dc79c3a1d61a4efa6dff52a1011eaf","target":"record","created_at":"2026-05-18T04:08:24Z","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":"a08211d3315bf9252d05effbe5a1cf627850fa695005670103ca5ccb32bb29c2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2011-01-05T09:22:34Z","title_canon_sha256":"444b0562aab0536a88b82e2e696dee3189dc482362e421b2177319b56a7e3248"},"schema_version":"1.0","source":{"id":"1101.0915","kind":"arxiv","version":1}},"canonical_sha256":"98a5448f17c7a48c01161ccc2b8a4950df09b76afba54cece0ee2fafc5574d3e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"98a5448f17c7a48c01161ccc2b8a4950df09b76afba54cece0ee2fafc5574d3e","first_computed_at":"2026-05-18T04:08:24.392890Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:08:24.392890Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"iBAq8Mf/EanM4NQVJyKiDT+p8DYV8j71Mryvqb1uKNT4HhbM7iMubocOOyhWOhQEbBXMF1A86ZsLDCawlY0NBg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:08:24.393504Z","signed_message":"canonical_sha256_bytes"},"source_id":"1101.0915","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:78714188334412117098e203f8e66e7cc7dc79c3a1d61a4efa6dff52a1011eaf","sha256:31848b5c7946f2c9146268e25d83f100c89ead9ab2ee97f3ffb50ab77c19e230"],"state_sha256":"c7c34de66d4adbeabb2cf3a95dedf3a5df7ab01ab395276fd4031ede7606d0b8"}
