The study, "Connecting Droplet Adhesion with Sperm Kinematics: A New Paradigm in Sperm Quality Monitoring," was recently published in Advanced Materials Interfaces. By measuring that force using a ...

The adhesion of this mechano-regulated surface ... As the number of microfibres increases, the maximum volume of a water droplet (liquid capacity) that the MRS can hold vertically against gravity ...

But that adhesion begins at the moment of impact ... at just the angle of total internal reflection. If I place a drop of water on the glass disk, that increases the refractive index, and ...

Physicists at the University of Zurich have developed a system that enables them to switch back and forth the adhesion and stiction (static friction) of a water drop on a solid surface.

"The ferrofluid-water interaction resembles a cupcake, with the surrounding ring only at the base of the droplet," explained the Ikerbasque professor Lourdes Basabe, who leads the cluster.

The new project took a modified approach, investigating the feasibility of a static water droplet acting as variable liquid lens. The results were published in Results in Optics. "This was inspired by ...

The result is a computer-controlled system that does just that: allows users to direct a water droplet across a board as they like, and even combine it with other droplets. It works using a 19th ...

Scientists in Belgium have uncovered a new way to shake things up. Violent bouncing of a water droplet coated with oil causes the oil layer to move inside and fracture into many oily globs.
