A team of researchers working at the University of Twente has solved the mystery of why a drop of oil bounces repeatedly when dropped in a water/ethanol gradient but eventually falls to the bottom of a jar. In their paper ...
A team of researchers affiliated with several institutions in China has found a way to force liquid drops to spiral as they rebound after landing on a manipulated surface. In their paper published in the journal Nature Communications, ...
From the wind-whipped surface of the open ocean, to trillions of tiny water drops in clouds, the air-water interface—water's skin— is the site for crucial natural processes, including ocean-atmosphere exchange and cloud ...

Hypoxic dead zones, which occur when dissolved oxygen levels in water drop so low that fish and other aquatic animals living there suffocate, are well-documented problems in many coastal waters.

In nature, there is no such thing as a truly clean surface. Contact with normal air is sufficient to coat any material with a thin layer of molecules. This "molecular dirt" can change the properties of the material considerably, ...

(Phys.org)—A team of researchers with the University of Côte d'Azur in France has found that drops ejected by an oscillating surface can at times travel faster than the surface that ejected them. In their paper published ...
Researchers from Duke University have uncovered the detailed mechanics of the way fungal spores have evolved to harness the power of merging water droplets to launch in a uniform manner.

In previous papers, University of Pennsylvania physicists investigated the "coffee ring effect," the ring-shaped stain of particles left after drops of coffee evaporate. In one paper, they learned how to undo this effect ...

The surface tension of a liquid is a measure of the cohesive forces that hold the molecules together. It is responsible for a water drop assuming a spherical shape and for the effects of surfactants to produce bubbles and ...
