Cage Breaking Far from Equilibrium
Jared Popowski, Nico Schramma, Edan Lerner +1
Active matter can flow and yield under conditions where passive matter jams and slows down, as self-propulsion significantly modulates particle escape from local cages. How activit…
Coalescence of Printed Yield Stress Filaments in Direct Ink Writing
Hugo L. França, Daniël Tieman, James D. Shemilt +2
In direct ink writing (DIW), neighbouring filaments of yield-stress inks are deposited side-by-side and are expected to merge into smooth, mechanically robust structures. Unlike Ne…
Odd Droplets: Fluids with Odd Viscosity and Highly Deformable Interfaces
Hugo França, Maziyar Jalaal
Flows with deformable interfaces are commonly controlled by applying an external field or modifying the boundaries that interact with the fluid, but realizing such solutions can be…
Optimal disk packing of chloroplasts in plant cells
Nico Schramma, Eric R. Weeks, Maziyar Jalaal
Photosynthesis is vital for the survival of entire ecosystems on Earth. While light is fundamental to this process, excessive exposure can be detrimental to plant cells. Chloroplas…
ActiveCheerios: 3D-Printed Marangoni-Driven Active Particles at an Interface
Jackson K. Wilt, Nico Schramma, Jan-Willem Bottermans +1
Marangoni surfers are simple, cost-effective tabletop experiments that, despite their simplicity, exhibit rich dynamics and collective behaviors driven by physicochemical mechanism…
Fragmentation and aggregation of cyanobacterial colonies
Yuri Z. Sinzato, Robert Uittenbogaard, Petra M. Visser +2
Fluid flow has a major effect on the aggregation and fragmentation of bacterial colonies. Yet, a generic framework to understand and predict how hydrodynamics affects colony size r…
Ductile-to-brittle transition and yielding in soft amorphous materials: perspectives and open questions
Thibaut Divoux, Elisabeth Agoritsas, Stefano Aime +37
Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays and cementitious pastes to emulsions and physical gels encountered in food or biomedical e…
Elasto-viscoplastic Spreading: from Plastocapillarity to Elastocapillarity
Hugo L. Franc, Maziyar Jalaal, Cassio M. Oishi
We study the spreading of elastoviscoplastic (EVP) droplets under surface tension effects. The non- Newtonian material flows like a viscoelastic liquid above the yield stress and b…
Chloroplasts in plant cells show active glassy behavior under low light conditions
Nico Schramma, Cintia Perugachi Israëls, Maziyar Jalaal
Plants have developed intricate mechanisms to adapt to changing light conditions. Besides photo- and helio- tropism -- the differential growth towards light and the diurnal motion…
Emergence of bimodal motility in active droplets
Babak Vajdi Hokmabad, Ranabir Dey, Maziyar Jalaal +5
To explore and react to their environment, living micro-swimmers have developed sophisticated strategies for locomotion - in particular, motility with multiple gaits. To understand…
Stress-Induced Dinoflagellate Bioluminescence at the Single Cell Level
Maziyar Jalaal, Nico Schramma, Antoine Dode +3
One of the characteristic features of many marine dinoflagellates is their bioluminescence, which lights up nighttime breaking waves or seawater sliced by a ship's prow. While the…
