Dynamic variables of drop impact such as force, drag, pressure, and stress distributions are
key to understanding a wide range of natural and industrial processes. While the study of …

Soft materials consist of basic units that are significantly larger than an atom but much
smaller than the overall dimensions of the sample. The label “soft condensed matter” …

Soil erosion is a geomorphological and, at the same time, a land degradation process that
may cause environmental and property damage, loss of livelihoods and services as well as …

Droplet impact has been imaged on different rigid, smooth, and rough substrates for three
liquids with different viscosity and surface tension, with special attention to the lower impact …

The maximum spreading of drops impacting on smooth and rough surfaces is measured
from low to high impact velocity for liquids with different surface tensions and viscosities. We …

Irrigation is limited by water scarcity. Here, we show how a drip irrigation system inspired by
the leaf of the fig tree Ficus religiosa (also known as the bodhi tree) can improve irrigation …

Droplets splash when they impact dry, flat substrates above a critical velocity that depends
on parameters such as droplet size, viscosity, and air pressure. By imaging ethanol drops …

Soft-sediment deformation structures (SSDS) have been the focus of attention for over 150
years. Existing unconstrained definitions allow one to classify a wide range of features under …

Understanding the response of granular matter to intrusion of solid objects is key to
modelling many aspects of behaviour of granular matter, including plastic flow. Here we …

The maximum spreading of an impinging droplet on a rigid surface is studied for low to high
impact velocity, until the droplet starts splashing. We investigate experimentally and …
