Impact dynamics of flexible hydrogels on solid substrates of different wettabilities
Akash Chowdhury, Surjyasish Mitra, Sushanta K. Mitra
In this work, we perform experiments with spherical polyacrylamide (PAAm) hydrogel drops/spheres, spanning a broad range of shear moduli and impact velocities on hydrophilic (plasm…
Motile Escherichia coli-laden Droplets Exhibit Reduced Adhesion and Anomalous Wetting Behavior
Sirshendu Misra, Sudip Shyam, Priyam Chakraborty +1
Hypothesis: Bacterial contamination of surfaces poses a major threat to public health. Designing effective antibacterial or self-cleaning surfaces requires understanding how bacter…
Spontaneous rolling on a 90 degree incline
Surjyasish Mitra, A-Reum Kim, Boxin Zhao +1
On perfectly vertical surfaces, rolling is conventionally deemed impossible without external torque. While various species like geckos and spiders exhibit vertical locomotion, they…
A versatile multilayer liquid-liquid encapsulation technique
Utsab Banerjee, Sirshendu Misra, Sushanta K. Mitra
Hypothesis: Generating multi-layer cargo using conventional methods is challenging. We hypothesize that incorporating a Y-junction compound droplet generator to encase a target cor…
Interface Dynamics at a Four-fluid Interface during Droplet Impact on a Two-Fluid System
Akash Chowdhury, Sirshendu Misra, Sushanta K. Mitra
We investigate the interfacial dynamics involved in the impact of a droplet on a liquid-liquid system, which involves the impingement of an immiscible core liquid drop from a verti…
A density functional theory approach to interpret elastowetting of hydrogels
Priyam Chakraborty, Surjyasish Mitra, A-Reum Kim +2
Sessile hydrogel drops on rigid surfaces exhibit wetting/contact morphology intermediate between liquid drops and glass spheres. Using density functional theory, we reveal the cont…
Flexible hydrogels connecting adhesion and wetting
A-Reum Kim, Surjyasish Mitra, Sudip Shyam +2
Raindrops falling on window panes spread upon contact, whereas hail can cause dents or scratches on the same glass window upon contact. While the former phenomenon resembles classi…
