Ionically Counter‐Programmable Phase‐Separation of Superstable Star‐Biopolyamide Coacervates for Electrothermally‐Responsive Pseudosolid Smart Windows

Advanced Science, EarlyView.
We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

Sandwich‐Structured Aramid Composite Papers with Heterogeneous Dielectric Layers for Integrated Corona Resistance and Thermal Conductivity [PDF]

Advanced science
A sandwich‐structured aramid composite paper was designed to integrate high corona resistance and thermal conductivity. The fluorinated graphene/aramid surface layers effectively dissipate space charges to suppress corona discharge. Meanwhile, the boron nitride nanotube/aramid core layer constructs continuous heat‐conduction pathways.

Molecular Conversion of Thermally Stable Cu‐Ag Networks for Mechanically Robust Printed Electronics

Advanced Science, EarlyView.
An air‐processable Cu–Ag reactive ink enables in situ formation of an Ag‐surface‐enriched Cu conductive network. Optimized Ag distribution suppresses Cu oxidation while preserving continuous electrical pathways, allowing printed conductors to achieve high conductivity, reduced migration, and stable operation at extreme temperatures up to 800 °C in air.

Enhancing Surface Icephobic Performance via Spontaneous Fracture Characteristics of Ice Crystals Regulated by Structural Scale Under Shear Flow Conditions

Advanced Science, EarlyView.
Aerodynamic shear induces spontaneous ice fracture and detachment on hydrophobic surfaces, governed by the interplay between initial ice‐crystal size, growth orientation, and interfacial adhesion. Unexpectedly, microstructural anchoring on superhydrophobic surfaces suppresses ice shedding.

Photo‐Induced Stepwise Liquid Crystal Phase Transition Enabled by Hydrazone Photoswitch [PDF]

Advanced science
A judiciously designed bistable hydrazone photoswitch enables a photo‐induced stepwise “order‐disorder” phase transition in liquid crystals. The linear‐to‐bent isomerization disrupts molecular packing, allowing precise tuning of phase transition temperatures.
