Lubricated surfaces are known to display extreme liquid repellency. Such behaviour is now confirmed to be due to the formation of a film between the surface and the repelled liquid, with a thickness profile following the Landau–Levich–Derjaguin law.</description><identifier>ISSN: 1745-2473</identifier><identifier>EISSN: 1745-2481</identifier><identifier>DOI: 10.1038/nphys4177</identifier><language>eng</language><publisher>London: Nature Publishing Group UK</publisher><subject>132/124 ; 639/301/923/1030 ; 639/766/189 ; Atomic ; Boundary layer ; Classical and Continuum Physics ; Complex Systems ; Condensed Matter Physics ; Film thickness ; Hydroplaning ; Lubricants & lubrication ; Mathematical and Computational Physics ; Molecular ; Optical and Plasma Physics ; Physics ; Surface chemistry ; Theoretical ; Thin films ; Tires ; Wetting</subject><ispartof>Nature physics, 2017-10, Vol.13 (10), p.1020-1025</ispartof><rights>Springer Nature Limited 2017</rights><rights>Copyright Nature Publishing Group Oct 2017</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c332t-83b94c78a99f0090ca9b54fc9b4dfd18844be2af012958accdf4a6776384c1543</citedby><cites>FETCH-LOGICAL-c332t-83b94c78a99f0090ca9b54fc9b4dfd18844be2af012958accdf4a6776384c1543</cites><orcidid>0000-0002-5859-170X</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1038/nphys4177$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1038/nphys4177$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,776,780,27901,27902,41464,42533,51294</link.rule.ids></links><search><creatorcontrib>Daniel, Dan</creatorcontrib><creatorcontrib>Timonen, Jaakko V.
