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 ...

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
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
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.

Tailored Diketopyrrolopyrrole Derivatives for Efficient Deep‐Red Organic Lasers
Tailored diketopyrrolopyrrole derivatives exhibit high stable amplified spontaneous emission with single or dual bands. Incorporated into distributed‐feedback lasers based on one‐ and two‐dimensional dichromated‐gelatin diffractive gratings, these materials provide a robust, flexible platform for integrated organic deep‐red light sources. ABSTRACT Deep‐

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‐

A migration‐permissive bioink composed of methacrylated collagen type I and thiolated hyaluronic acid enables 3D bioprinting of breast cancer‐stroma models. Single‐cell tracking reveals that adipose stromal cells enhance tumor cell motility and stromal invasion, accompanied by collagen remodeling, and a shift in tumor cell morphology.

Navier-Stokes equation with slip-like boundary condition
The aim of this note is to investigate a time-discretized 2-dimensional Navier-Stokes equation with a slip-like boundary condition, which arises in the melting ice problem. We prove the existence and uniqueness of a weak solution.
