Worm-Inspired Active Filaments Sweep Disorder into Order
The ability of single active filaments to cluster smaller particles could inspire new materials for building soft robots that perform biological functions.
Researchers have proposed and tested a strategy that enables a single active filament to act as a sweeping agent. Thanks to the versatility of polymer architectures, the investigation opens up a huge molecular-design space.

Reversible kink instability drives ultrafast jumping in nematodes and soft robots
A soft jumping robot inspired by nematodes demonstrates ultrafast jumping using reversible kink instability and stiffness.
Excited to share our new work in @science.org #Robotics that shows how reversible kinks can help nematodes perform jumps 1000 times faster than you can blink! scim.ag/4iDIa1i

We also introduce a "pathway" of configurations, that includes all the relevant orientations between two particles, providing a clean representation of the "important" slice of the potential energy landscape. Super useful!

We take two models describing particles with an heterogeneous surface charge and showed that they can be matched, yielding a considerable improvement of the more "approximated" of the two models. Importantly, the procedure can be extended beyond the setting we considered (the linear PB regime)

Fabrication and Characterization of Bimetallic Silica-Based and 3D-Printed Active Colloidal Cubes
Simulations on self-propelling active cubes reveal interesting behaviors at both the individual and the collective level, emphasizing the importance of developing experimental analogues that allow testing these theoretical predictions. The majority of experimental realizations of active colloidal cubes rely on light actuation and/or magnetic fields to have a persistent active mechanism and lack material versatility. Here, we propose a system of active bimetallic cubes whose propulsion mechanism is based on a catalytic reaction and study their behavior. We realize such a system from synthetic silica cuboids and 3D-printed microcubes, followed by the deposition of gold and platinum layers on their surface. We characterize the colloids’ dynamics for different thicknesses of the gold layer at low and high hydrogen peroxide concentrations. We show that the thickness of the base gold layer has only a minor effect on the self-propulsion speed and, in addition, induces a gravitational torque during sedimentation. For low activity, this gravitational torque orients the particles such that their velocity director is pointing out of the plane, thus effectively suppressing propulsion. We find that a higher active force can remedy the effects of torque, resulting in all possible particle orientations, including one with the metal cap on the side, which is favorable for in-plane propulsion. Finally, we use 3D printing to compare our results to cubes made from a different material, size, and roundness and demonstrate that the speed scaling with increasing particle size originates from the size-dependent drag. Our experiments extend the fabrication of active cubes to different materials and propulsion mechanisms and highlight that the design of active particles with anisotropic shapes requires consideration of the interplay between shape and activity to achieve favorable sedimentation and efficient in-plane propulsion.
Anisotropic active particles cannot always simply turn to change their orientation after having reached a surface: as we show for active colloidal cubes, this can lead to several populations with different particles speeds. Now out in Langmuir! pubs.acs.org/doi/10.1021/...

Active Polymers Tie Themselves in Knots
Simulations show that polymers that include inert and self-propelled components are more likely to form and retain knots, with possible applications in materials engineering.
DNA and other long molecules can become spontaneously entangled with themselves. Simulations have now shown that a molecule comprising two different polymers joined end to end—one inert, the other self-propelling—can accumulate knots more readily than a single-component chain of the same length.

Falsifiability Test for Classical Nucleation Theory
Classical nucleation theory (CNT) is built upon the capillarity approximation, i.e., the assumption that the nucleation properties can be inferred from the bulk properties of the melt and the crystal....
🧪In our new paper (journals.aps.org/prl/abstract...) in collaboration with Russo, Romano, Rovigatti and Sciortino groups in Rome / Venice, we look at Classical Nucleation Theory: a popular model of nucleation process, n is a key phenomena in self-assembly, self-organization and phase transitions.
