Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

High-Performance Thin Film Composite Nanofiltration (NF) Membrane Constructed on Modified Polyvinylidene Fluoride (PVDF) Substrate

Membranes
The inherent hydrophobic nature of PVDF material renders it challenging to establish a stable aqueous hydration layer, thereby limiting its suitability as a substrate for the preparation of nanofiltration (NF) membranes.

Charge‐Tunable Coacervate Micelles for Separator Engineering in Lithium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
A separator engineering strategy based on charge‐tunable complex coacervate core micelles (C3Ms) is presented to form an ion‐selective layer regulating polysulfide transport in Li–S batteries. The micelles enable uniform adsorption onto commercial polypropylene separators and infiltration throughout the internal pore network, suppressing polysulfide ...

An Electrowetting Pump

Advanced Functional Materials, EarlyView.
A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

3D Hydrodynamic Flow Lithography

Advanced Functional Materials, EarlyView.
ABSTRACT Continuous‐ and stop‐flow lithography are widely used to fabricate multi‐dimensional microstructures whose cross‐sectional morphology is dictated by the flow profile of multiple co‐flowing streams. Here, we introduce three‐dimensional hydrodynamic flow lithography (3D HFL), a platform for programmable generation of multi‐layered flow profiles ...

Self‐Assembled Lipids as Soft Dielectrics

Advanced Functional Materials, EarlyView.
Self‐assembled lipid bilayers serve as soft dielectric materials for ultrathin electronics. Using liquid‐metal parallel‐plate junctions, the capacitance and dielectric breakdown of dehydrated lipid films are characterized. Dielectric behavior is controlled by lipid molecular structure, cholesterol content, and assembly conditions, providing molecular ...
