Reverse Janssen effect in narrow granular columns
Shivam Mahajan, Michael Tennenbaum, Sudhir N. Pathak +6
When grains are added to a cylinder, the weight at the bottom is smaller than the total weight of the column, which is partially supported by the lateral walls through wall/grain f…
Swelling thermodynamics and phase transitions of polymer gels
Michael S. Dimitriyev, Ya-Wen Chang, Paul M. Goldbart +1
We present a pedagogical review of the swelling thermodynamics and phase transitions of polymer gels. In particular, we discuss how features of the volume phase transition of the g…
Extreme thermodynamics with polymer gel tori: harnessing thermodynamic instabilities to induce large-scale deformations
Ya-Wen Chang, Michael S. Dimitriyev, Anton Souslov +5
When a swollen, thermoresponsive polymer gel is heated in a solvent bath, it expels solvent and deswells. When this heating is slow, deswelling proceeds homogeneously, as observed…
Transition from turbulent to coherent flows in confined three-dimensional active fluids
Kun-Ta Wu, Jean Bernard Hishamunda, Daniel T. N. Chen +5
Transport of fluid through a pipe is essential for the operation of macroscale machines and microfluidic devices. Conventional fluids only flow in response to external pressure. We…
