The variation of contact angle of liquid sessile drops on solids has been attributed to roughness (Wenzel2), the static charge effect (Holly,3 Ponter and Yekta-Fard3) and contamination at the solid surface or in the liquid and gaseous phases.doi:10.1080/00218468508079683...
of angle measurements, since with time the drop may spread out or dry up, as in the case of inks based on volatile solvents. The measurement values depend also on the temperature of the liquid and ambient temperature. This is why they should be conducted in stable conditions. On the ...
First, temperature measurements were used to characterize the solid/liquid distribution and, second, tribo-electric probes were used to obtain the local solids fluxes. The measurement technique has proven to be a very reliable and reproducible method to determine the extent of liquid and solid ...
Impact of Microdrops on Solids: Modelling and Simulation In particular, the transition between different flow regimes, such as deposition or rebound of the microdrop, is seen to be strongly dependent on the treatment of the dynamic contact angle. Variations in wettability, which influence the ......

The reaction forces applied on the substrate lead to the bending deformation of these outer pillars towards the interior of the liquid37, as depicted in the inset of Fig. 2(a). Furthermore, we found that the contact angle θ gradually decreases in each stick stage as the liquid ...
Contact Angles and the Surface Free Energy of Solids Odile Carrier, Daniel Bonn, in Droplet Wetting and Evaporation, 2015 2.2.1 Advancing and Receding Contact Angles The Young–Laplace equation gives only one equilibrium contact angle for a homogeneous pure liquid on a perfectly flat, rigid, and...
The contact angle of the liquid on the gripper surface can be controlled by application of voltage. As a result, the liquid bridge shape will deform gradually changing the lifting force. At the initial stage of the micromanipulation scheme, the surface would be hydrophobic (contact angle around ...
