  Enhanced dip coating on a soft substrate

  A solid, withdrawn from a wetting liquid bath, entrains a thin liquid film. This simple process, first described by Landau, Levich, and Derjaguin (LLD), is commonly observed in everyday life. It also plays a central role in liquid capture by (...)

  Active boundary layers in confined active nematics

  The role of boundary layers in conventional liquid crystals is commonly related to the mesogen anchoring on confining walls. In the classical view, anchoring enslaves the orientational field of the passive material under equilibrium conditions. (...)

  Elastic Instability of Cubic Blue Phase Nano Crystals in Curved Shells

  Many crystallization processes, including biomineralization and ice-freezing, occur in small and curved volumes, where surface curvature can strain the crystal, leading to unusual configurations and defect formation. The role of curvature on (...)

  Overload wave-memory induces amnesia of a self-propelled particle

  Information storage is a key element of autonomous, out-of-equilibrium dynamics, especially for biological and synthetic active matter. In synthetic active matter however, the implementation of internal memory in self-propelled systems is often (...)

  Adaptive strategies in Kelly’s horse races model

  We formulate an adaptive version of Kelly’s horse model in which the gambler learns from past race results using Bayesian inference. We characterize the cost of this gambling strategy and we analyze the asymptotic scaling of the difference (...)

  Self-assembly of emulsion droplets through programmable folding

  In the realm of particle self-assembly, it is possible to reliably construct nearly arbitrary structures if all the pieces are distinct(1-3), but systems with fewer flavours of building blocks have so far been limited to the assembly of exotic (...)

  Adaptive Phototaxis of a Swarm of Mobile Robots using Positive and Negative Feedback Self-Alignment

  In this paper, we explore how robots in a swarm can individually exploit collisions to produce self-organizing behaviours at the macroscopic scale. We propose to focus on two behaviours that modify the orientation of a robot during a collision, (...)

  Contactless Rheology of Soft Gels Over a Broad Frequency Range

  We report contactless measurements of the viscoelastic rheological properties of soft gels. The experiments are performed using a colloidal-probe atomic force microscope in a liquid environment and in dynamic mode. The mechanical response is (...)

  Lessons from Biomass Valorization for Improving Plastic-Recycling Enzymes

  Synthetic polymers such as plastics exhibit numerous advantageous properties that have made them essential components of our daily lives, with plastic production doubling every 15 years. The relatively low cost of petroleum-based polymers (...)

  Programming Directed Motion with DNA-Grafted Particles

  Colloidal particles can be programmed to interact in complex ways by functionalizing them with DNA oligonucleotides. Adding DNA strand-displacement reactions to the system allows these interparticle interactions to respond to specific changes (...)
