The above is possible for weakly attractive solid surfaces that show spatial variation of nanoscale roughness at large scales and chemical heterogeneities at small scales. Our model also indicates that the capillary-motion driven by interfacial fluctuations can improve the energy-efficiency of nano-fluidic devices. We have discussed the implications for two scenarios: 1) liquid inside a pore, and 2) an axisymmetric liquid droplet on a flat surface.falseCapillary-motion | Crystalline surface | Interfacial fluctuations | Thermal response | Wetting behaviorArticle16 December 20201138066arJournal0
