Motility and interfacial instability of confined chemically active droplets
Pawan Kumar, Sobiya Ashraf, Naveen Tiwari +2
Microorganisms navigating through narrow spaces encounter significant hydrodynamic challenges. To overcome these constraints and sustain efficient motion, they employ adaptive stra…
Clustering Dynamics of SiO2-Pt Active Janus Colloids
Harishwar Raman, Aniket Shivhare, Amit Kumar +5
Active colloid clustering is central to understanding non-equilibrium self-organization, with implications for programmable active materials and synthetic or biological assemblies.…
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…
