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 ...

Extensional rheology examines the response of polymer solutions to uniaxial stretching flows, a phenomenon intrinsic to many industrial and natural processes. In these systems, the interplay of ...

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.
