Drying kinematics selects open honeycomb fold networks on solvent-extracted viscoelastic thin films and gels
Fan Zhao, Surjyasish Mitra, Sunandan Tandon +3
Solvent extraction and drying of substrate-supported viscoelastic films and gels produce quasiperiodic networks of three-armed surface folds. In this Letter, we examine the physica…
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 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…
