    The rational design of out-of-equilibrium demixing transitions remains challenging. Active fluids are used to control the liquid–liquid phase separation of passive DNA nanostars and establish the activity-based control of the phase diagram.

    Highly ordered crystalline porous solids are useful for many applications. This Perspective explores the evolution of these systems from the ordered state to the glassy and liquid states, discusses the different types of porous liquid and considers possible applications of these disordered systems.

    Liquid repellent coatings are important for several applications. Now, a coating that repels ultralow surface tension liquids and simultaneously shows robustness and transparency is reported.

    Dense suspensions of hard particles readily display discontinuous shear thickening under shear but not reversible shear jamming. Here it is shown that the formation of interparticle hydrogen bonds is crucial for the shear jamming of these suspensions.

    A combination of hard, soft and nanoscale organic components results in robust superhydrophobic surfaces that can withstand mechanical abrasion and chemical oxidation, and exhibit excellent substrate adhesion.

    Porous rubber microbeads suspended in a gel are found to exhibit a negative acoustic index of refraction, which makes these metamaterials promising for underwater acoustic applications.

    At sufficiently low temperature, liquid water crystallizes into ices with cubic or hexagonal symmetry. A simulation study now shows that the nucleation of water into atomic stackings of cubic and hexagonal ices occurs through a metastable precursor phase with tetragonal symmetry, and that this scenario provides an explanation for the unusual pressure dependence of water’s homogeneous crystal-nucleation temperature.

    Viscoelastic gels can be made by using flow to induce structure into solutions containing surfactant micelles. However, the gels disintegrate soon after flow stoppage. By using a microfluidic-assisted laminar-flow process to generate very high extension rates, it is now shown that permanent gels can be made, creating new opportunities for applications.

    In most suspensions viscosity decreases with increasing shear rate. The opposite effect, shear thickening, is a problem for industrial applications. An understanding of how particle interactions in suspensions influence shear thickening may lead to a solution of this problem through the design of smart suspensions.
