Asymmetric bistability of chiral particle orientation in viscous shear flows
Andreas Zöttl, Francesca Tesser, Daiki Matsunaga +3
The migration of helical particles in viscous shear flows plays a crucial role in chiral particle sorting. Attaching a non-chiral head to a helical particle leads to a rheotactic t…
Pitch Controls the Flexibility of Helical Ribbons
Lucas Prévost, Anke Lindner, Olivia du Roure
Helical objects are often implemented in electronic or mechanical micro-systems, requiring a precise understanding of their mechanical properties. While helices formed by cylindric…
Frustrated run and tumble of swimming E-coli bacteria in nematic liquid crystals
Martyna Goral, Eric Clement, Thierry Darnige +2
In many situations bacteria move in complex environments, as for example in soils, oceans or the human gut-track microbiome. In these natural environments, carrier fluids such as m…
Dynamics of flexible filaments in oscillatory shear flows
Francesco Bonacci, Brato Chakrabarti, David Saintillan +2
The fluid-structure interactions between flexible fibers and viscous flows play an essential role in various biological phenomena, medical problems, and industrial processes. Of pa…
Shaping Nanoscale Ribbons into Micro-Helices of Controllable Radius and Pitch
Lucas Prévost, Dylan M. Barber, Marine Daïeff +5
We report fabrication of highly flexible micron-sized helices from nanometer-thick ribbons. Building upon the helical coiling of such ultra-thin ribbons mediated by surface tension…
Fiber buckling in confined viscous flows: an absolute instability described by the Ginzburg-Landau equation
Jean Cappello, Olivia du Roure, François Gallaire +2
We explore the dynamics of a flexible fiber transported by a viscous flow in a Hele-Shaw cell of height comparable to the fiber height. We show that long fibers aligned with the fl…
