Toothpaste, face creams, hair gel, mayonnaise and ketchup are household items that most people don't think twice about, but in terms of their flow behavior, they have unusual properties. They're all ...

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 ...

So far, flow-induced transitions and structures formed by the assembly of surfactant micelles have been reversible. Now, a microporous extensional flow process forms a permanent gel, which remains ...
