An alternative description of the interfacial energy of a liquid in contact with a solid
TL;DR: This paper investigates the relationship between the long-range Coulomb effects in the ionic solution and the interfacial energy, and concentrates on experiments in which other surface effects are minimized and in which chemical reactions at the surface are absent or frozen.

Boundary layer theory
TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.
