Gelation of functional peptides by trivalent cations at the air-water interface
Stephen A. Crane, Felipe Jimenez Angeles, Monica Olvera de la Cruz +2
We report a mechanism for gelation at fluid interfaces driven by multivalent-cation-mediated bridging. At the air-water interface, peptides with bound lanthanide cations undergo a…
A sweeping twist defect as a topological flagellum that drives colloid motion
Qi Xing Zhang, Claire Dore, Mojtaba Rajabi +2
Nematic liquid crystals can dramatically reconfigure under dynamic forcing, providing exciting opportunities in active matter. Here, we study a hybrid disk colloid rotated by an ex…
Scallop Theorem for Swimming in Anisotropic Fluids
Mojtaba Rajabi, Enej Caf, Qi Xing Zhang +6
In isotropic fluids like water, micrometer-scale swimmers have evolved swim strokes to translate despite their tiny size. As described by Purcell in his Scallop Theorem, reciprocal…
Interfacial Rheology of Lanthanide Binding Peptide Surfactants at the Air-Water Interface
Stephen A. Crane, Felipe Jimenez-Angeles, Yiming Wang +12
Peptide surfactants (PEPS) are studied to capture and retain rare earth elements (REEs) at air-water interfaces to enable REE separations. Peptide sequences, designed to selectivel…
Swimmers at Interfaces Enhance Interfacial Transport
Jiayi Deng, Mehdi Molaei, Nicholas G. Chisholm +1
The behavior of fluid interfaces far from equilibrium plays central roles in nature and in industry. Active swimmers trapped at interfaces can alter transport at fluid boundaries w…
Bicontinuous interfacially jammed emulsion gels with nearly uniform sub-micrometer domains via regulated co-solvent removal
Tiancheng Wang, Robert A. Riggleman, Daeyeon Lee +1
Porous materials possess numerous useful functions because of their high surface area and ability to modulate the transport of heat, mass, fluids, and electromagnetic waves. Unlike…
