Biogenic bubbles enable microbial escape from physical confinement
Babak Vajdi Hokmabad, Thomas Appleford, Hao Nghi Luu +3
Immotile microbes inhabit nearly every environment on Earth, from soils and sediments to food matrices -- yet how they disperse through these physically confining environments is p…
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…
Oscillatory rheotaxis of active droplets in microchannels
Ranabir Dey, Carola M. Buness, Babak Vajdi Hokmabad +2
Biological microswimmers are known to navigate upstream of an external flow (positive rheotaxis) in trajectories ranging from linear, spiral to oscillatory. Such rheotaxis stems fr…
Chemotactic self-caging in active emulsions
Babak Vajdi Hokmabad, Suropriya Saha, Jaime Agudo-Canalejo +2
A common feature of biological self-organization is how active agents communicate with each other or their environment via chemical signaling. Such communications, mediated by self…
Emergence of bimodal motility in active droplets
Babak Vajdi Hokmabad, Ranabir Dey, Maziyar Jalaal +5
To explore and react to their environment, living micro-swimmers have developed sophisticated strategies for locomotion - in particular, motility with multiple gaits. To understand…
Topological Stabilization and Dynamics of Self-propelling Nematic Shells
Babak Vajdi Hokmabad, Kyle A. Baldwin, Carsten Krüger +2
Liquid shells (e.g. double emulsions, vesicles etc.) are susceptible to interfacial instability and rupturing when driven out of mechanical equilibrium. This poses a significant ch…
