In a new study, researchers have observed the freezing of saltwater droplets at a molecular level, offering new insights for de-icing and anti-icing technologies. Contrary to conventional wisdom, these droplets don't conform ...
If you've seen water drops dance and jitter on a hot pan or griddle, you've seen the Leidenfrost effect in action. Or you may have seen the "Mythbusters" episode where Adam and Jamie thrust their wet fingers and hands into ...
Modern applications use self-cleaning strategies and digital microfluids to control individual droplets of fluids on flat surfaces but existing techniques are limited by the side-effects of high electric fields and high temperatures. ...
In a new study, researchers have propelled water nanodroplets across a graphene surface at speeds of up to 250 km (155 miles) per hour—which, for comparison, is about twice as fast as a sprinting cheetah. The water droplets' ...
A new study published on Microsystems and Nanoengineering by Kazuhiro Kobayashi and Hiroaki Onoe details the development of a flexible and reflective multicolor display system that does not require continued energy supply ...
(Phys.org)—There are many cool videos showing the Leidenfrost effect, which occurs when water droplets levitate and skid around on top of a very hot surface, rather than immediately evaporating like they do at temperatures ...
(Phys.org)—In a normal rainbow, red is always on "top" while violet is on the "bottom." This is true whether the rainbow is created by a glass prism or by water droplets in the sky, and is due to the way that these materials ...
(PhysOrg.com) -- By rapidly manipulating colored oil droplets stacked on top of each other, a new electrowetting (EW) technique could lead to the development of electronic paper displays that can produce high-resolution color ...
Each year at its annual meeting, the American Physical Society's Division of Fluid Dynamics sponsors a contest for the best images in a variety of categories, all related to the flow of fluids.
University of Oxford researchers have made a significant step towards realizing miniature bio-integrated devices, capable of directly stimulating cells. Their work has been published in the journal Nature.

A drop or droplet is a small volume of liquid, bounded completely or almost completely by free surfaces. A drop may form when liquid accumulates at the lower end of a tube or other surface boundary, producing a hanging drop called a pendant drop. Drops may also be formed by the condensation of a vapor or by atomization of a larger mass of liquid.
