Spatiotemporal crystallization of an active fluid
Olga Bantysh, Ramon Reigada, Rodrigo C. V. Coelho +3
The emergence of long-range spatiotemporal order from intrinsic chaos is a central challenge in far-from-equilibrium physics. In active fluids, such as cytoskeletal networks drivin…
Active nematic pumps
Ignasi Vélez-Ceron, Rodrigo C. V. Coelho, Pau Guillamat +4
Microfluidics involves the manipulation of flows at the microscale, typically requiring external power sources to generate pressure gradients. Alternatively, harnessing flows from…
Density-polarity coupling in confined active polar films: asters, spirals, and biphasic orientational phases
Mathieu Dedenon, Claire A. Dessalles, Pau Guillamat +3
Topological defects in active polar fluids can organise spontaneous flows and influence macroscopic density patterns. Both of them play, for example, an important role during anima…
Probing active nematics with in-situ microfabricated elastic inclusions
Ignasi Vélez-Cerón, Pau Guillamat, Francesc Sagués +1
In this work, we report a direct measurement of the forces exerted by a tubulin/kinesin active nematic gel as well as its complete rheological characterization, including the quant…
Integer topological defects of cell monolayers -- mechanics and flows
Carles Blanch-Mercader, Pau Guillamat, Aurélien Roux +1
Monolayers of anisotropic cells exhibit long-ranged orientational order and topological defects. During the development of organisms, orientational order often influences morphogen…
Quantifying material properties of cell monolayers by analyzing integer topological defects
Carles Blanch-Mercader, Pau Guillamat, Aurélien Roux +1
In developing organisms, internal cellular processes generate mechanical stresses at the tissue scale. The resulting deformations depend on the material properties of the tissue, w…
Taming active turbulence with patterned soft interfaces
Pau Guillamat, Jordi Ignés-Mullol, Francesc Sagués
Active matter embraces systems that self-organize at different length and time scales, often exhibiting turbulent flows. Here, we use a quasi-two-dimensional nematically ordered la…
Probing the shear viscosity of an active nematic
Pau Guillamat, Jordi Ignés-Mullol, Suraj Shankar +2
In vitro reconstituted active systems, such as the ATP-driven microtubule bundle suspension developed by the Dogic group, provide a fertile testing ground for elucidating the pheno…
Patterning active materials with addressable soft interfaces
Pau Guillamat, Jordi Ignés-Mullol, Francesc Sagués
Motor-proteins are responsible for transport inside cells. Harnessing their activity is key towards developing new nano-technologies, or functional biomaterials. Cytoskeleton-like…
