The ordinary equations of fluid flow predict an infinite friction force at that line, so some extra physics must act at very small scales.","title":"Moving contact lines and dynamic wetting","topic_ref":null,"why":"Coating, inkjet printing, oil recovery and microfluidic devices depend on how fast a liquid can wet or dewet a solid."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"7a825c5c00d33b62e371e3769546f5338a06f02c5d234ce8602c61be90e57f13","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"1a985c2d4c56ac7fe026c371021d34ed215d177e7d218e5ec482b0db17cf686c","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"r3X3rQosGsR8ejbEZGN3nt1y7fK-dhZgiFlG9_-HAOMFq2_GnFkpb_O0OLKf8IpQKQvI9ErsDIIHO1Pu5PMvBw"},"schema":"pubphys.envelope/1"},"record_hash":"7a825c5c00d33b62e371e3769546f5338a06f02c5d234ce8602c61be90e57f13","leaf_index":214}
