Rapid in-situ quantification of rheo-optic evolution for cellulose spinning in ionic solvents

Autor: Du, Jianyi, Paez, Javier, Otero, Pablo, Sanchez, Pablo B.

It is critical to monitor the structural evolution during deformation of complex fluids for the optimization of many manufacturing processes, including textile spinning. However, in situ measurements in a textile spinning process suffer from paucity

Capillarity-driven thinning dynamics of entangled polymer solutions

Autor: Du, Jianyi, Ohtani, Hiroko, Kiziltas, Alper, Ellwood, Kevin, McKinley, Gareth H.

We analyze the capillarity-driven thinning dynamics of entangled polymer solutions described by the Doi-Edwards-Marrucci-Grizzuti (DEMG) model and the Rolie-Poly (RP) model. Both models capture polymer reptation, finite rates of chain retraction and

Capillarity-driven thinning and breakup of weakly rate-thickening fluids

Autor: Du, Jianyi, Ohtani, Hiroko, Ellwood, Kevin, McKinley, Gareth H.

A number of commercial fluids, including synthetic automotive oils, food and consumer products containing polymer additives exhibit weakly rate-thickening responses in the final stages of capillarity-driven thinning, where a large accumulated strain
