Emergence of Order in Chemically Active Droplets: Temporal Dynamics and Collective Behavior
Sobiya Ashraf, Pawan Kumar, Prateek Dwivedi +3
Collective behaviors such as swarming, chemical signaling, and clustering are fundamental to biological microorganisms, enabling hierarchical colony formation, coordinated motion,…
Chemical interactions in active droplets
Prateek Dwivedi, Sobiya Ashraf, Pawan Kumar +2
Interactions among biologically active agents is facilitated by their self-generated chemical and hydrodynamic fields. In order to elucidate the pair-wise interactions between such…
Motility and pair-wise interactions of chemically active droplets in 1-D confinement
Pawan Kumar, Prateek Dwivedi, Sobiya Ashraf +2
Self-propelled droplets serve as ideal model systems to delve deeper into understanding of the motion of biological micro-swimmers by simulating their motility. Biological microorg…
Rheotaxis of Active Droplets
Prateek Dwivedi, Atishay Shrivastava, Dipin Pillai +1
Rheotaxis is a well-known phenomenon among microbial organisms and artificial active colloids, wherein the swimmers respond to an imposed flow. We report the first experimental evi…
Solute Induced Jittery Motion of Self-Propelled Droplets
Prateek Dwivedi, Bishwa Ranjan Si, Dipin S. Pillai +1
The intriguing role of the presence of solutes in the activity of a self-propelling droplet is investigated. A system of self-propelling micron sized 4-pentyl-4-biphenylcarbonitril…
