Selective trapping of bacteria in porous media by cell length
David Gao, Zeyuan Wang, Mihika Jain +2
Bacteria commonly inhabit porous environments such as host tissues, soil, and marine sediments, where complex geometries constrain and redirect their motion. Although bacterial mot…
Machine Learning-Informed Scattering Correlation Analysis of Sheared Colloids
Lijie Ding, Yihao Chen, Changwoo Do
We carry out theoretical analysis, Monte Carlo simulations and Machine Learning analysis to quantify microscopic rearrangements of dilute dispersions of spherical colloidal particl…
X-ray diffraction reveals the consequences of strong deformation in thin smectic films: dilation and chevron formation
Jean de Dieu Niyonzima, Haifa Jeridi, Lamya Essaoui +14
Smectic liquid crystals can be viewed as model systems for lamellar structures for which there has been extensive theoretical development. We demonstrate that a nonlinear energy de…
Soft Metamaterials: Adaptation and Intelligence
Colin Scheibner, Michel Fruchart, Vincenzo Vitelli
We provide a perspective on soft metamaterials and biomatter with a special emphasis on future research directions at the interface between material intelligence and adaptation.
Entanglements and Whitehead Products: Generalizing Kleman's Construction to Higher-Dimensional Defects
Gareth P. Alexander, Randall D. Kamien
We review the interpretation of Whitehead products in homotopy theory as an entanglement of topological defects in ordered media.
Phase-separation during sedimentation of dilute bacterial suspensions
Bryan O. Torres Maldonado, Ranjiangshang Ran, K. Lawrence Galloway +3
Numerous natural systems depend on the sedimentation of passive particles in presence of swimming microorganisms. Here, we investigate the dynamics of the sedimentation of spherica…
