The presence of nanoparticles in a millimetric liquid drop impacting on a solid surface can suppress splashing at higher impact velocities. This mechanism is affected by the nanoparticles concentration and the coating molecules at their surface.

The effect of surfactant on the thickness of a thin film bounded by a solid surface and a moving liquid drop was investigated. We proposed a model so that parameters from the liquid drop can be stated in a parameter that acts as normal pressure to the thin film. Using the lubrication approximation, the model was reduced to a set of nonlinear partial differential equations in terms of the film thickness and surfactant concentration. Since we were interested in the role of the surfactant in lifting up the drop, we assumed that the density of the drop is higher than the density of the thin film. Numerically, the results show that the presence of the surfactant tends to delay the decrease of the film thickness insignificantly. However, when the surfactant was added into the system, it tends to significantly increase the film thickness for a certain range value of the normal pressure.

Small drops adhering to a ceiling under a gravitational field are found in many industrial and natural situations. This work investigates a novel scheme to rapidly remove these pendent drops from a solid surface by vibrating the drop. In the experiments, a water drop pendent from a solid surface is vibrated at a fixed frequency while increasing the vibration amplitude. Upon repeating the experiments using different frequencies, it is revealed that there exist resonant frequencies at which the minimum vibration amplitudes inducing a fall-off of the pendent drops are remarkably less than the detaching amplitudes at neighboring frequencies. These frequencies are supposed to correspond to the resonant frequencies of different drop oscillation modes. They are compared with the resonant frequencies predicted by relatively simple analyses, and the factors causing discrepancy between them are discussed.
