Nota di contenuto Intro -- < -- named-book-part-body& -- #62 -- < -- p& -- #62 -- The rapid advancement of open microfluidics in recent years has prompted the need for updating our inaugural book, & -- #x0201C -- Open-Channel Microfluidics,& -- #x0201D -- initially published in 2019. Additionally, we aim to expand the scope of our earlier publication, & -- #x0201C -- Open Microfluidics,& -- #x0201D -- released in 2016, to encompass the examination of the dynamics associated with open capillary-driven microflows.< -- /p& -- #62 -- < -- p& -- #62 -- The second edition delves into capillary fl -- Acknowledgments -- Author biographies -- Jean Berthier -- Ashleigh B Theberge -- Erwin Berthier -- Foreword to the first edition -- Foreword to the second edition -- Outline placeholder -- I.1 Paper-based microfluidics -- I.2 Thread-based microfluidics -- I.3 Sessile droplet microfluidics -- I.4 Open-channel microfluidics -- I.5 Book contents -- References -- Chapter The theoretical basis of capillarity -- 1.1 Introduction -- 1.1.1 Surface tension -- 1.1.2 Laplace pressure -- 1.1.3 Liquid-liquid surface tension -- 1.1.4 Contact with solid surfaces: Young's law -- 1.1.5 Neumann's construction -- 1.1.6 The work of adhesion, the work of cohesion, and the Young-Dupré equation -- 1.1.7 Solid surface energy: Zisman's approach -- 1.1.8 Wetting and pinning -- 1.1.9 Wenzel's law -- 1.1.10 The Cassie-Baxter law -- 1.1.11 Capillary rise -- 1.1.12 Marangoni convection -- References -- Chapter The Lucas-Washburn-Bosanquet approach -- 2.1 Introduction -- 2.2 The Bosanquet equation -- 2.3 Simplification: inertial and viscous regimes -- 2.3.1 The inertial evanescent regime -- 2.3.2 The viscous regime: the Lucas-Washburn-Rideal law -- 2.3.3 Transition between the two regimes -- 2.3.4 Examples -- 2.4 The full Bosanquet solution.
