Uniaxial extensional viscosity of semidilute DNA solutions
Sharadwata Pan, Duc At Nguyen, P. Sunthar +2
The extensional rheology of polymeric liquids has been extensively examined through experiments and theoretical predictions. However, a systematic study of the extensional rheology…

Shear thinning in dilute and semidilute solutions of polystyrene and DNA
Sharadwata Pan, Duc At Nguyen, B. Duenweg +3
The viscosity of dilute and semidilute unentangled DNA solutions, in steady simple shear flow, has been measured across a range of temperatures and concentrations. For polystyrene…

Effect of stretching-induced changes in hydrodynamic screening on coil-stretch hysteresis of unentangled polymer solutions
Ranganathan Prabhakar, Chandi Sasmal, Duc At Nguyen +2
Extensional rheometry and Brownian Dynamics simulations of flexible polymer solutions confirm predictions based on blob concepts that coil--stretch hysteresis in extensional flows…
