Anomalous crystalline ordering of particles in a viscoelastic fluid under high shear

Kavli Affiliate: David A. Weitz | Authors: Sijie Sun, Nan Xue, Stefano Aime, Hyoungsoo Kim, Jizhou Tang, Gareth H. McKinley, Howard A. Stone, David A. Weitz | Summary: Addition of particles to a viscoelastic suspension dramatically alters the properties of the mixture, particularly when it is sheared or otherwise processed. Shear-induced stretching of the polymers […]

Anomalous crystalline ordering of particles in a viscoelastic fluid under high shear

Kavli Affiliate: David A. Weitz | First 5 Authors: Sijie Sun, Nan Xue, Stefano Aime, Hyoungsoo Kim, Jizhou Tang | Summary: Addition of particles to a viscoelastic suspension dramatically alters the properties of the mixture, particularly when it is sheared or otherwise processed. Shear-induced stretching of the polymers results in elastic stress that causes a […]

Connecting cooperative transport by ants with the physics of active swimmers

Kavli Affiliate: Ariel Amir | First 5 Authors: Tabea Heckenthaler, Tobias Holder, Ariel Amir, Ofer Feinerman, Ehud Fonio | Summary: Some ant species are known as efficient transporters that can cooperatively carry food items which would be too large for a single ant. Previous studies of cooperative transport focused on the role of individual ants […]

Connecting cooperative transport by ants with the physics of self-propelled particles

Kavli Affiliate: Ariel Amir | First 5 Authors: Tabea Heckenthaler, Tobias Holder, Ariel Amir, Ofer Feinerman, Ehud Fonio | Summary: Paratrechina longicornis ants are known for their ability to cooperatively transport large food items. Previous studies have focused on the behavioral rules of individual ants and explained the efficient coordination using the coupled-carrier model. In […]

Nonlinear waves in flexible mechanical metamaterials

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Bolei Deng, Jordan R. Raney, Katia Bertoldi, Vincent Tournat, | Summary: Flexible mechanical metamaterials are compliant structures engineered to achieve unique properties via the large deformation of their components. While their static character has been studied extensively, the study of their dynamic properties is still at an […]

Recurrent flow patterns as a basis for turbulence: predicting statistics from structures

Kavli Affiliate: Michael P. Brenner | First 5 Authors: Jacob Page, Peter Norgaard, Michael P. Brenner, Rich R. Kerswell, | Summary: A dynamical systems approach to turbulence envisions the flow as a trajectory through a high-dimensional state space transiently visiting the neighbourhoods of unstable simple invariant solutions (E. Hopf, Commun. Appl. Maths 1, 303, 1948). […]

Self-regulating surfaces for efficient liquid collection

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Christian Machado, Yuehan Yao, Emma Feldman, Joanna Aizenberg, Kyoo-Chul Kenneth Park | Summary: To achieve efficient liquid collection, a surface must regulate incoming liquid accumulation with outgoing liquid transport. Often, this can be proposed to be achieved by functionalizing surfaces with non-wetting characteristics. Yet, there remain fundamental, […]
