Microfluidic Oscillatory Rheology of Transported Soft Particles
Matteo Milani, Joshua D. McGraw, Anke Lindner +1
Microfluidic channels have emerged as useful tools to control dynamic forcing on transported microscale objects, as encountered in emulsions, biological flows, and other soft matte…
Linear poroelastic response of thin permeable gel films
Caroline Kopecz-Muller, Joshua D Mcgraw, Thomas Salez
When a hydrophilic and deformable porous material is immersed in a bath, it may absorb the solvent and expand by several times its volume, thus forming a highly soft and porous hyd…
Polymeric Solvents Control Swelling-Induced Surface Creasing
Zechao Jiang, Zhaoyu Ding, Shaohua Yang +7
Surface creasing in swelling polymer gels is commonly attributed to compressive strain or interlayer mismatch, yet its general control remains unclear. Here we show that solvent po…
Taylor dispersion in a soft tube
Aditya Jha, Masoodah Gunny, Joshua D Mcgraw +2
Diffusion of a solute along a tube is enhanced by hydrodynamic flow, a phenomenon known as Taylor dispersion. In microfluidic applications, the compliance of the tube boundaries mo…
Transport of soft matter in complex and confined environments
Joshua D Mcgraw
Brownian motion provides a bedrock for the understanding of soft condensed matter and, therefore, of the physical description of the microscopic biological world. Inspired by this…
Short Chains Enhance Slip of Highly Entangled Polystyrenes during Thin Film Dewetting
S. Mostafa Sabzevari, Joshua D. McGraw, Paula Wood-Adams
We investigate the effect of short chains on slip of highly entangled polystyrenes (PS) during thin film dewetting from non-wetting fluorinated surfaces. Binary and ternary mixture…
