  Silicon chambers for enhanced incubation and imaging of microfluidic droplets

  Droplet microfluidics has become a powerful tool in life sciences, underlying digital assays, single-cell sequencing or directed evolution, and it is making foray in physical sciences as well. Imaging and incubation of droplets are crucial, yet (...)

  Nanoparticle Taylor Dispersion Near Charged Surfaces with an Open Boundary

  The dispersive spreading of microscopic particles in shear flows is influenced both by advection and thermal motion. At the nanoscale, interactions between such particles and their confining boundaries become unavoidable. We address the roles (...)

  Dramatic Effect of Water Structure on Hydration Forces and the Electrical Double Layer

  Forces between hydrophilic surfaces mediated by water are important in various systems from lipid membranes and solid surfaces to colloids and macromolecules, first discovered as a significant addition to DLVO forces at the nanoscale. These (...)

  Statistical self-organization of a gas of interacting walking drops in a confining potential

  A drop bouncing on a vertically-vibrated surface may self-propel forward by standing waves and travels along a fluid interface. This system called walking drop forms a non-quantum wave-particle association at the macroscopic scale. The dynamics (...)

  Helfrich-Hurault elastic instabilities driven by geometrical frustration

  The Helfrich-Hurault (HH) elastic instability is a well-known mechanism behind patterns that form as a result of strain upon liquid crystal systems with periodic ground states. In the HH model, layered structures undulate and buckle in response (...)

  Morphological computation and decentralized learning in a swarm of sterically interacting robots

  Whereas naturally occurring swarms thrive when crowded, physical interactions in robotic swarms are either avoided or carefully controlled, thus limiting their operational density. Here, we present a mechanical design rule that allows robots to (...)

  Linear Instability of Turbulent Channel Flow br

  Laminar-turbulent pattern formation is a distinctive feature of the intermittency regime in subcriticalplane shear flows. By performing extensive numerical simulations of the plane channel flow, we show thatthe pattern emerges from a spatial (...)

  Molecular Computation for Molecular Classification

  DNA as an informational polymer has, for the past 30 years, progressively become an essential molecule to rationally build chemical reaction networks endowed with powerful signal-processing capabilities. Whether influenced by the silicon world (...)

  Microscopic foundation of the mu(I) rheology for dense granular flows on inclined planes

  Macroscopic and microscopic properties of dense granular layers flowing down inclined planes are obtained from Discrete-Element-Method simulations for both frictionless and frictional grains. Three fundamental observations for dense granular (...)

  Cross-sections of doubly curved sheets as confined elastica

  Although thin films are typically manufactured in planar sheets or rolls, they are often forced into three-dimensional (3D) shapes, producing a plethora of structures across multiple length scales. To understand this complex response, previous (...)
