Flow-induced bending response rheometer to measure viscoelastic bending of microrods
Barrett T Smith, Michal Czerepaniak, Maciej Lisicki +1
Soft, microscale hydrogel fibers and rods play important roles in tissue engineering, flexible electronics, soft robotics, drug delivery, sensors, and other applications. Their vis…
Rigid body rotation and chiral reorientation combine in filamentous E. coli swimming in low-Re flows
Richard Z. DeCurtis, Yongtae Ahn, Jane E. Hill +1
When treated with antibiotics below the minimum inhibitory concentration, bacterial cell division turns off, but cell growth does not. Thus, rod-like bacteria, including E. coli, c…
Mixing soft and rigid particles in a hopper: soft particles induce flow intermittency and avalanches
Saeed Alborzi, Sara M. Hashmi
Instabilities and avalanches in granular flows represent hallmarks of failure: they can both disrupt industrial process flows and signal dangerous conditions, like those in grain s…
Stiffer alginate gels deposit more efficiently in microchannel flows
Barrett T Smith, Sara M Hashmi
The behavior of cross-linking polymer solutions as they transition from liquid-like to solid-like material in flow determines success or failure in several applications. Dilute pol…
