When the boundary walls have different temperatures, the confined liquid experiences a temperature gradient along the sawtooth edges, which can induce a thermoosmotic flow. A mesoscale molecular simulation approach is here employed to investigate the flows which are contrasted using an analytical approach. Microchannels can be composed by one or two ratcheted walls which can be straight or cylindrical. Varying the channel geometry can not only change the overall fluid flux, but also vary the flow patters from shear to capillary type, or even to extensional type flows. This scheme does not require multiphase fluids or any movable channel parts, although they are possible to be implemented. The proposed principle is then very versatile to locally manipulate complex fluids, and a promising tool to recover waste heat, to facilitate cooling of microchips, and to manufacture portable lab-on-a-chip devices 000820808 536__ $$0G:(DE-HGF)POF3-553$$a553 - Physical Basis of Diseases (POF3-553)$$cPOF3-553$$fPOF III$$x0 000820808 588__ $$aDataset connected to CrossRef 000820808 7001_ $$0P:(DE-Juel1)130920$$aRipoll, Marisol$$b1 000820808 773__ $$0PERI:(DE-600)2191476-X$$a10.1039/C6SM01692H$$gVol. 12, no. 41, p. 8564 - 8573$$n41$$p8564 - 8573$$tSoft matter$$v12$$x1744-6848$$y2016 000820808 8564_ $$uhttps://juser.fz-juelich.de/record/820808/files/c6sm01692h.pdf$$yRestricted 000820808 8564_ $$uhttps://juser.fz-juelich.de/record/820808/files/c6sm01692h.gif?subformat=icon$$xicon$$yRestricted 000820808 8564_ $$uhttps://juser.fz-juelich.de/record/820808/files/c6sm01692h.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000820808 8564_ $$uhttps://juser.fz-juelich.de/record/820808/files/c6sm01692h.jpg?subformat=icon-180$$xicon-180$$yRestricted 000820808 8564_ $$uhttps://juser.fz-juelich.de/record/820808/files/c6sm01692h.jpg?subformat=icon-640$$xicon-640$$yRestricted 000820808 8564_ $$uhttps://juser.fz-juelich.de/record/820808/files/c6sm01692h.pdf?subformat=pdfa$$xpdfa$$yRestricted 000820808 909CO $$ooai:juser.fz-juelich.de:820808$$pVDB 000820808 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130920$$aForschungszentrum Jülich$$b1$$kFZJ 000820808 9131_ $$0G:(DE-HGF)POF3-553$$1G:(DE-HGF)POF3-550$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lBioSoft – Fundamentals for future Technologies in the fields of Soft Matter and Life Sciences$$vPhysical Basis of Diseases$$x0 000820808 9141_ $$y2016 000820808 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000820808 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bSOFT MATTER : 2015 000820808 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000820808 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000820808 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000820808 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000820808 915__ $$0StatID:(DE-HGF)0400$$2StatID$$aAllianz-Lizenz / DFG 000820808 915__ $$0StatID:(DE-HGF)0550$$2StatID$$aNo Authors Fulltext 000820808 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000820808 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000820808 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000820808 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000820808 9201_ $$0I:(DE-Juel1)ICS-2-20110106$$kICS-2$$lTheorie der Weichen Materie und Biophysik $$x0 000820808 980__ $$ajournal 000820808 980__ $$aVDB 000820808 980__ $$aUNRESTRICTED 000820808 980__ $$aI:(DE-Juel1)ICS-2-20110106 000820808 981__ $$aI:(DE-Juel1)IBI-5-20200312 000820808 981__ $$aI:(DE-Juel1)IAS-2-20090406
