Researchers from NITech, Japan, have recently developed a novel full-field extensional rheo-optical technique that can accurately characterize structural deformations in a complex fluid under ...

This is because the plastic is constantly expanding or stretching in those processes. Two polymers may have identical shear flow behavior, but they could exhibit different extensional flow behavior ...

Researchers have taken a close look at the flow of materials that have both liquid-like and solid-like states, such as toothpaste, mayonnaise, and ketchup, using both simulations and experiments.
