    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.

    Slit-like nanochannels of pristine graphite and activated carbon, fabricated by van der Waals assembly of pristine or sculpted graphite crystals, enable comprehensive ionic response measurements and the systematic realization of their ion transport properties. These are attributed to optimal combinations of (mobile) surface charge and slippage effects at the channel wall surface in both pristine and activated nanochannels.

    This is a turning point for nanofluidics. Recent progress allows envisioning both fundamental discoveries for the transport of fluids at the ultimate scales, and disruptive technologies for the water–energy nexus.

    The antifogging properties of a structured surface can be considerably enhanced if the feature size is small enough and if the feature shapes are cones rather than cylinders.

    Experiments show that a colloidal particle straddling an air/water interface feels a viscous drag that is unexpectedly larger than that in the bulk.
