Chiral interactions between tropocollagen molecules determine the collagen microfibril structure
Art'om Zolotarjov, Roland Kröger, Dmitri O. Pushkin
Collagen is the most abundant structural protein in animals, forming hierarchically organised fibrils that provide mechanical support to tissues. Despite detailed structural studie…
Interfacial activity dynamics of confined active droplets
Prashanth Ramesh, Babak Vajdi Hokmabad, Arnold J. T. M. Mathijssen +2
Active emulsions can spontaneously form self-propelled droplets or phoretic micropumps. It has been predicted that the interaction with their self-generated chemical fields can lea…
Stochastic gel-shatter cycles in coalescence-fragmentation models
Brennen T. Fagan, Niall J. MacKay, Dmitri O. Pushkin +1
We describe a new phenomenon in models of coalescence and fragmentation, that of gel-shatter cycles. These are dynamical, unforced, stochastic cycles in which slow, approximately d…
Confinement enhances the diversity of microbial flow fields
Raphaël Jeanneret, Dmitri O. Pushkin, Marco Polin
Despite their importance in many biological, ecological and physical processes, microorganismal fluid flows under tight confinement have not been investigated experimentally. Stron…
A solvable model of axisymmetric and non-axisymmetric droplet bouncing
Matthew Andrew, Julia M. Yeomans, Dmitri O. Pushkin
We introduce a solvable Lagrangian model for droplet bouncing. The model predicts that, for an axisymmetric drop, the contact time decreases to a constant value with increasing Web…
Entrainment dominates the interaction of microalgae with micron-sized objects
Raphaël Jeanneret, Vasily Kantsler, Marco Polin
The incessant activity of swimming microorganisms has a direct physical effect on surrounding microscopic objects, leading to enhanced diffusion far beyond the level of Brownian mo…
