Controlling the complex dynamics of active colloidsthe autonomous locomotion of colloidal particles and their spontaneous assemblyis challenging yet crucial for creating functional, out-of-equilibrium colloidal systems potentially useful for nano- and micromachines. Herein, by introducing the synthesis of active “patchy” colloids of various low-symmetry shapes, we demonstrate that the dynamics of such systems can be precisely tuned. The low-symmetry patchy colloids are made in bulk via a clust...

Molecular motors are essential to the living, generating fluctuations that boost transport and assist assembly. Active colloids, that consume energy to move, hold similar potential for man-made materials controlled by forces generated from within. Yet, their use as a powerhouse in materials science lacks. Here we show a massive acceleration of the annealing of a monolayer of passive beads by moderate addition of self-propelled microparticles. We rationalize our observations with a model of colli...

Abstract Achieving both performances and functionalities of energy storage devices at extreme conditions remains a critical challenge due to the property trade-offs of materials. Here, we demonstrate highly ion-conducting, stretchable, and ultradurable double network (DN) ionogel films, where ionic liquids are confined in chemically-coupled DNs consisting of hard and soft polymers, for high-temperature flexible supercapacitors (hfSCs). Both mechanical and electrochemical integrities at high temp...

Reversible and specific interaction between single-stranded DNA on colloidal particles have opened up a new path way of building up colloidal superstructures. DNA-coated microspheres can be bound with other particles with complementary DNA brushes below the melting temperature and can be unbound above the melting temperature. However, due to their random Brownian motion, the particles form random (or glassy) structures in most cases or small crystals when cooling is extremely slow. Therefore, to...

Non-spherical colloidal building blocks introduce new design principles for self-assembly, making it possible to realize optical structures that could not be assembled previously. With this added complexity, the phase space expands enormously so that computer simulation becomes a valuable tool to design and assemble structures with useful optical properties. We recently demonstrated that tetrahedral clusters and spheres, interacting through a DNA-mediated short-range attractive interaction, self...
