This study experimentally explores fluid breakup and Leidenfrost dynamics for droplets
impacting a heated millimetric post. Using high-speed optical and infrared imaging, we …

Superhydrophobic surfaces with excellent water repellence show huge potential in diverse
application fields such as self-cleaning and energy harvesting. This potential of …

We experimentally observe a new phenomenon, the formation of a toroidal region of lower
film thickness in the center of the lamella formed during high Weber number water droplet …

The influence of surface roughness, especially regularly patterned micro-structures on the
physical outcomes of droplet impacts, is far from fully understood. In order to get a deeper …

Droplet impact dynamics on a superhydrophobic surface with a cubic protrusion was
simulated by the lattice Boltzmann method and the contact time reduction mechanism due to …

Phenomena involving bubble flow play a significant role in numerous industrial, natural, and
scientific systems. Thus, liquid–gas interfaces must be considered the influence of surface …

The phenomenon of droplet impact is widely observed in nature and industrial processes.
No matter the intrinsic wettability (hydrophobic, hydrophilic, and superhydrophobic) of the …

The fluid dynamics of liquid droplet impact on surfaces hold significant relevance to various
industrial applications. However, high impact velocities introduce compressible effects …

Hypothesis: The shape of the wetted region after a droplet impact can vary significantly even
in the early phase of the process. How much of the early spreading process occurs within …

Herein, we report the electrochemical monitoring of attoliters of water droplets in an organic
medium by the electrolysis of an extracted redox species from the continuous phase upon …
