Fluid ejections in nature
Elio J. Challita, Pankaj Rohilla, M. Saad Bhamla
From microscopic fungi to colossal whales, fluidic ejections are a universal and intricate phenomenon in biology, serving vital functions such as animal excretion, venom spraying,…
Conservation Tools: The Next Generation of Engineering--Biology Collaborations
Andrew Schulz, Cassie Shriver, Suzanne Stathatos +7
The recent increase in public and academic interest in preserving biodiversity has led to the growth of the field of conservation technology. This field involves designing and cons…
Directional takeoff, aerial righting, and adhesion landing of semiaquatic springtails
Victor M. Ortega-Jimenez, Elio J. Challita, Baekgyeom Kim +4
Springtails (Collembola) have been traditionally portrayed as explosive jumpers with incipient directional takeoff and uncontrolled landing. However, for these collembolans who liv…
Ultrafast reversible self-assembly of living tangled matter
Vishal P. Patil, Harry Tuazon, Emily Kaufman +4
Tangled active filaments are ubiquitous in nature, from chromosomal DNA and cilia carpets to root networks and worm blobs. How activity and elasticity facilitate collective topolog…
Amorphous Entangled Active Matter
William Savoie, Harry Tuazon, M. Saad Bhamla +1
The design of amorphous entangled systems, specifically from soft and active materials, has the potential to open exciting new classes of active, shape-shifting, and task-capable '…
Oxygenation-Controlled Collective Dynamics in Aquatic Worm Blobs
Harry Tuazon, Emily Kaufman, Daniel I. Goldman +1
Many types of organisms utilize group aggregation as a method for survival. The freshwater oligochaete, California blackworms Lumbriculus variegatus form tightly entangled structur…
Slingshot spiders build tensed underdamped webs for ultrafast launches and speedy halts
Elio J. Challita, Symone Alexander, Sarah Han +4
We develop a mathematical model to capture the web dynamics of slingshot spiders (Araneae: Theridiosomatidae), which utilize a tension line to deform their orb webs into conical sp…
A polymer-based technique to remove pollutants from soft contact lenses
Katherine Burgener, M. Saad Bhamla
Purpose: To demonstrate an alternative to the rinse and rub (RR) method for cleaning pollutants from the exterior surface of soft contact lenses. This proposed technique is termed…
Placing Marangoni instabilities under arrest
M. Saad Bhamla, Gerald G. Fuller
Soap bubbles occupy the rare position of delighting and fascinating both young children and scientific minds alike. Sir Isaac Newton, Joseph Plateau, Carlo Marangoni, and Pierre-Gi…
Interfacial mechanisms for stability of surfactant-laden films
M. Saad Bhamla, Chew Chai, Marco A. Alvarez-Valenzuela +2
Thin liquid films are central to everyday life. They are ubiquitous in modern technology (pharmaceuticals, coatings), consumer products (foams, emulsions) and also serve vital biol…
Autonomous Motility of Active Filaments due to Spontaneous Flow-Symmetry Breaking
Gayathri Jayaraman, Sanoop Ramachandran, Somdeb Ghose +4
We simulate the nonlocal Stokesian hydrodynamics of an elastic filament which is active due a permanent distribution of stresslets along its contour. A bending instability of an in…
