Multifunctional Solid Polymer Electrolyte Films Integrating Intrinsic Self‐Healing and Dual Photo‐/pH‐Responsive Ionic Sensing for Intelligent Flexible Electronics

Advanced Functional Materials, EarlyView.
Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

Meniscus‐Guided Soft‐Lithographic Assembly of Grid‐Type Molecular Martensite Films for Single‐Crystal‐Like Actuation

Advanced Functional Materials, EarlyView.
A meniscus‐guided microtransfer molding strategy enables scalable fabrication of grid‐type molecular martensite films with b‐axis‐correlated preferential texture. Sequential growth across microchannel intersections creates structurally continuous grids and robust thermoelastic actuation (∼11% strain, > 50 cycles, maximum force density: 7.1 × 109 N m−3).

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 ...

Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes

Advanced Functional Materials, EarlyView.
Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.

Computational Fluid Dynamics Analysis of Slip Flow and Heat Transfer at the Entrance Region of a Circular Pipe

Applied Sciences
In the era of sustainable development goals (SDGs), energy efficient heat transfer systems are a must. Convective heat transfer within circular pipes is an important field of research on a rarely addressed limitation of fluid flows. Vacuum solar tubes is

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‐
