A biofilm is an interface-associated colloidal dispersion of bacterial cells and excreted
polymers in which microorganisms find protection from their environment. Successful …

Control of the directional bounce of droplets impacting solid surfaces is crucial for many
agricultural and industrial applications. However, for the universal impact process of …

Pine needles have evolved alongside rainfall for millennia. Needles are robust to raindrop
impacts and the portions of mass impacting raindrops leave behind. Pine needles also …

Impacting drops are ubiquitous and the corresponding impact force is their most studied
dynamic quantity. However, impact forces arising from collisions with curved surfaces are …

Vibration attenuation and control is a typical topic in mechanical, civil and aeronautical
engineering. In recent years, there has been extensive research on smart materials and …

In this study, we explore the vibration damping characteristics of singular liquid drops of
varying viscosity and surface tension resting on a millimetric cantilever. Cantilevers are …

We have studied the motion of liquid drops on an aluminum surface subject to vertical
vibrations. By combining with a laser Doppler vibrometer (LDV) system, a novel …

In this experimental study, we combine drop impact into porous media and onto a single
fiber to study drop impact into fiber arrays inspired by mammalian fur coats. In our 3D-printed …

Understanding whether a droplet adheres to or detaches from a flexible filament upon axial
impact is of significant interest, particularly in the context of raindrop impact on natural …

Liquid drops placed on substrates may vibrate, slide, take history-dependent shapes, and
even detach or break up when subjected to external forces. Although CFD tools can …
