Directional Control of Droplet Motion via Geometric Gating
Manoj K. Chaudhury, Vanessa Elias, Michelle Fruge
We explore new methods for inducing the movement of water droplets on elastomeric substrates, such as polydimethylsiloxane (PDMS). Our approach builds upon the well-known phenomeno…
Spontaneous Emulsification: Elucidation of the Local Processes
Monicka Kullappan, Wes Patel, Manoj K. Chaudhury
Micro and/or Nano sized emulsions are formed when an organic liquid gently comes in contact with water in the presence of a surfactant, where no external agitation is required. Man…
Adhesive Release via Elasto-Osmotic Stress Driven Surface Instability
Khulood Al-sakkaf, Monicka Kullappan, Manoj K. Chaudhury
Recent studies demonstrated that an elastomer containing hygroscopic inclusions absorbs moisture and swell. Here we show that a thin film of such an elastomer bonded to a rigid sub…
Elastowetting of Soft Hydrogel Spheres
Aditi Chakrabarti, Amir Porat, Elie Raphaël +2
When a soft hydrogel sphere is placed on a rigid hydrophilic substrate, it undergoes arrested spreading by forming an axisymmetric foot near the contact line, while conserving its…
Normal contact and friction of rubber with model randomly rough surfaces
S. Yashima, V. Romero, E. Wandersman +4
We report on normal contact and friction measurements of model multicontact interfaces formed between smooth surfaces and substrates textured with a statistical distribution of sph…
Soft Lithography using Nectar Droplets
Saheli Biswas, Aditi Chakrabarti, Antoine Chateauminois +3
In spite of significant advances in replication technologies, methods to produce well-defined three dimensional structures are still at its infancy. Such a limitation would be evid…
