Viscoelastic fluids are everywhere, whether racing through your veins or through 1,300 kilometers of pipe in the Trans-Alaska Pipeline. Unlike Newtonian fluids, such as oil or water, viscoelastic fluids stretch like a sticky ...

Fluids such as water are Newtonian, and their viscous behavior is well understood. However, many common fluids are "viscoelastic." These fluids, such as those commonly found in cosmetics, soaps and paints, possess a combination ...

If you've ever splattered paint on a canvas or sprayed a cookie sheet with oil, you likely created—aside from a minor mess—a shower of droplets, ranging from dime-sized splotches to pencil-point specks.

Polymers are very large molecules consisting of thousands, even millions, of atoms bonded together in a repeating pattern similar to a chain. They make up many of the things around us we consider part of our everyday lives, ...

Swimming in a pool of syrup would be difficult for most people, but for bacteria like E. coli, it's easier than swimming in water. Scientists have known for decades that these cells move faster and farther in viscoelastic ...

(Phys.org) —A trio of researches with Université Paris Diderot has found that viscoelastic fluids spontaneously form wings which in turn cause the formation of geometric shapes when the fluid is shot out of a jet at high ...
Scale plays a major role in locomotion. Swimming microorganisms, such as bacteria and spermatozoa, are subjected to relatively small inertial forces compared to the viscous forces exerted by the surrounding fluid. Such low-level ...
