We present the results of a systematic study elucidating the role that dynamic surface tension has on the spreading and splashing dynamics of surfactant-laden droplets during the impact on hydrophobic substrates. Using four different surfactants at …
When a fast droplet impacts a pool of the same fluid, a thin ejecta sheet that dominates the early-time dynamics emerges within the first few microseconds. Fluid and impact properties are known to affect its evolution; we experimentally reveal that …
Droplets impacting dry solid substrates often splash above a certain threshold impact velocity. We *hypothesise* that substrate curvature alters splashing thresholds due to a modification to the lift force acting on the lamella at the point of …
