Probing Micro-Newton Forces on Solid/Liquid/Gas Interfaces Using Transmission Phase Shift

Abstract: Many of the nature and life systems are driven by capillary interactions on solid/liquid/gas interfaces. Here, we present a profilometry technique called transmission phase shift for visualizing the liquid/gas interfaces in three dimensions with high resolution. Using this approach, we probe the change in tiny forces with particle radius at a solid/liquid/gas interface. We provide the first direct evidence that in the issues of floating versus sinking at small-scale, Archimedes' principle should be generalized… Show more

“…The motions of droplet on an asymmetric surface are always related to the anisotropic properties of the surface, such as the direction-dependent triple-phase contact line, unbalanced force, and so on. These factors will influence the magnitude and distribution of the force applied on the droplet. , In this article, we also established a mechanical model from the perspective of force analysis to clearly explain the droplet performances on an inclined micro-conical superhydrophobic surface. As the size of the droplet is much larger than that of a micro-cone, the contact state between the droplet and each micro-cone can be considered as identical.…”

“…Therefore, the greater the height of the drop, the more severe the curvature of the shape it experiences. The influence of gravity on the drop shape can be described using the Bond number. The mean Bond numbers for water drops on glass and PTFE surfaces are 3.93 and 1.38, respectively, which indicates that gravity is a significant factor affecting the contact angles in our experiments.…”

“…It follows from Eqs. (40)(41)(42)(43)(44)(45) that the axial displacement and microstrain of the mid-plane, u 0 and s 0 , are independent of the transverse ones. Therefore, explicit solutions for u 0 and s 0 can be obtained by simultaneously solving Eqs.…”

“…Thus, the non-zero components of the different stress fields are obtained as follows: However, for the case that the beam microstructure is of a different stiffness, the Lame moduli of the microstructure would be independently defined. The Lame moduli of the microstructure can be determined experimentally by the direct testing a single crystal of the beam material, or by testing the shifts in the natural frequencies of the beam, as we decrease its size 44 .…”
