One-Step Self-Organized Multifunctional Micromotors via Evaporative Liquid-Liquid Phase Separation
Senthan Pugalneelam Parameswaran, Akshay Sidhi, Ambareesh Shrivastav +3
Active microcarriers capable of transporting multiple functional components and navigating complex environments are highly desirable for biomedical applications, yet their fabricat…
Field-Particle Interactions in Curved Flows for Shape-Asymmetric Active Particles
Derek C. Gomes, Tapan C. Adhyapak
We show that curvatures in general ambient flow profiles can align shape-asymmetric active particles, revealing a previously overlooked competition with externally applied aligning…
E. coli bacterium tumbling in bulk and close to surfaces: A simulation study
Pierre Martin, Tapan Chandra Adhyapak, Holger Stark
Motility is fundamental to the survival and proliferation of microorganisms. The E. coli bacterium propels itself using a bundle of rotating helical flagella. If one flagellum reve…
Shape-asymmetry and flexibility in active cross-stream migration in nonuniform shear
Derek C. Gomes, Tapan C. Adhyapak
We show that activity and broken fore-aft shape symmetry enable microswimmers to cross streamlines in nonuniform shear, a key yet overlooked factor in active cross-stream migration…
Nonlinear electrostatic oscillations in a cold magnetized electron-positron plasma
Prabal Singh Verma, Tapan Chandra Adhyapak
We study the spatio-temporal evolution of the nonlinear electrostatic oscillations in a cold magnetized electron-positron (e-p) plasma using both analytics and simulations. Using a…
Flow properties and hydrodynamic interactions of rigid spherical microswimmers
Tapan Chandra Adhyapak, Sara Jabbari-Farouji
We analyze a minimal model for a rigid spherical microswimmer and explore the consequences of its extended surface on the interplay between its self-propulsion and flow properties.…
Hydrodynamic instabilities in active cholesteric liquid crystals
Carl A. Whitfield, Tapan Chandra Adhyapak, Adriano Tiribocchi +3
We describe the basic properties and consequences of introducing active stresses, with principal direction along the local director, in cholesteric liquid crystals. The helical gro…
Dynamics of a bacterial flagellum under reverse rotation
Tapan Chandra Adhyapak, Holger Stark
To initiate tumbling of an E. coli, one of the helical flagella reverses its sense of rotation. It then transforms from its normal form first to the transient semicoiled state and…
Zipping and Entanglement in Flagellar Bundle of E. Coli: Role of Motile Cell Body
Tapan Chandra Adhyapak, Holger Stark
The course of a peritrichous bacterium such as E. coli crucially depends on the level of synchronization and self-organization of several rotating flagella. However, the rotation o…
Live Soap: Order, Fluctuations and Instabilities in Active Smectics
Tapan Chandra Adhyapak, Sriram Ramaswamy, John Toner
We construct a hydrodynamic theory of noisy, apolar active smectics, in bulk suspension or on a substrate. Our predictions include: quasi-long-ranged smectic order in dimension d =…
