Effect of edge disturbance on shear banding in polymeric solutions
Seunghwan Shin, Kevin D. Dorfman, Xiang Cheng
Edge instabilities are believed to be one of the possible causes of shear banding in entangled polymeric fluids. Here, we investigate the effect of edge disturbance on the shear-in…
Stable Frank-Kasper phases of self-assembled, soft matter spheres
Abhiram Reddy, Michael B. Buckley, Akash Arora +3
Single molecular species can self-assemble into Frank Kasper (FK) phases, finite approximants of dodecagonal quasicrystals, defying intuitive notions that thermodynamic ground stat…
Shear-banding and superdiffusivity in entangled polymer solutions
Seunghwan Shin, Kevin D. Dorfman, Xiang Cheng
Using high-resolution confocal rheometry, we study the shear profiles of well-entangled DNA solutions under large amplitude oscillatory shear (LAOS) in a rectilinear planar shear c…
One-parameter scaling theory for DNA extension in a nanochannel
E. Werner, G. K. Cheong, D. Gupta +2
Experiments measuring DNA extension in nanochannels are at odds with even the most basic predictions of current scaling arguments for the conformations of confined semiflexible pol…
Finite-size corrections for confined polymers in the extended de Gennes regime
T. St Clere Smithe, V. Iarko, A. Muralidhar +3
Theoretical results for the extension of a polymer confined to a channel are usually derived in the limit of infinite contour length. But experimental studies and simulations of DN…
Physical descriptions of the bacterial nucleoid at large scales, and their biological implications
Vincenzo G. Benza, Bruno Bassetti, Kevin D. Dorfman +4
Recent experimental and theoretical approaches have attempted to quantify the physical organization (compaction and geometry) of the bacterial chromosome with its complement of pro…
Exact computation of the mean velocity, molecular diffusivity and dispersivity of a particle moving on a periodic lattice
Kevin D. Dorfman
A straightforward analytical scheme is proposed for computing the long-time, asymptotic mean velocity and dispersivity (effective diffusivity) of a particle undergoing a discrete b…
Convective dispersion without molecular diffusion
Kevin D. Dorfman, Howard Brenner
A method-of-moments scheme is invoked to compute the asymptotic, long-time mean (or composite) velocity and dispersivity (effective diffusivity) of a two-state particle undergoing…
