In the past few decades, novel syntheses of a wide range of nanoparticles (NPs) with well‐
defined chemical composition and structure have opened tremendous opportunities in areas …

Stimuli‐responsive nanoparticle (NP) aggregation plays an increasingly important role in
regulating NP assembly into microscopic superstructures, macroscopic 2D, and 3D …

Janus structures have unique properties due to their distinct functionalities on opposing
faces, but have yet to be realized with flowing liquids. We demonstrate such Janus liquids …

Abstract 2D transition metal carbides and nitrides (MXenes), a class of emerging
nanomaterials with intriguing properties, have attracted significant attention in recent years …

Solid ferromagnetic materials are rigid in shape and cannot be reconfigured. Ferrofluids,
although reconfigurable, are paramagnetic at room temperature and lose their …

Nanoparticle surfactants (NPSs), formed by using dynamic interactions between
nanoparticles and complementary ligands at the liquid‐liquid interface, have emerged as …

Superwettable surfaces show great potential in water harvesting applications, however, a
scalable water harvesting surface remains elusive due to the trade‐off between water …

Liquid–fluid interfaces provide a platform both for structuring liquids into complex shapes
and assembling dimensionally confined, functional nanomaterials. Historically, attention in …

Liquids lack the spatial order required for advanced functionality. Interfacial assemblies of
colloids, however, can be used to shape liquids into complex, 3D objects, simultaneously …

Abstract Systems comprised of immiscible liquids held in non-equilibrium shapes by the
interfacial assembly and jamming of nanoparticle− polymer surfactants have significant …
