Fluxional Monomers Remodel Crystallinity at Low Loadings in Diketopyrrolopyrrole Co‐Thienothiophene Conjugated Polymers

open access: yesAngewandte Chemie, EarlyView.
Bullvalene is a fluxional molecule capable of adopting numerous conformations spontaneously; just like a Rubik's Cube. In this paper, we explore the incorporation of bullvalene into the backbone of a highly rigid conjugated polymer semiconductor and observe that the inherent fluxionality reduces average crystallite size.

Ultrafast Micrometric Laser Structuring of Polymer Surfaces for Highly Organized Skeletal Muscle Tissue Modeling

open access: yesAdvanced Science, EarlyView.
Standard cell culture supports were functionalized by laser‐structuring to generate advanced topographies tailored to skeletal muscle tissue. The physicochemical modifications of the polymeric surfaces and their interactions with cells were thoroughly investigated, confirming both safety and effectiveness in guiding muscle cell organization.

Synthesis of Ladder and Flexible Polysulfonimides Directly From Anionic Monomers: Investigating Structure–Property Convergence in Succinonitrile–Polymer Electrolyte Blends

open access: yesAngewandte Chemie, EarlyView.
Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Balancing Crystallization Kinetics and Lattice Strain Enables Thermally Stable Slot‐Die‐Coated Narrow‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Unbalanced crystallization in mixed Sn‐Pb perovskites causes film defects and instability. CsPbI3 nanocrystals serve as nucleation seeds to regulate growth during slot‐die coating. Resulting solar cells retain 80% efficiency after nine thermal cycles. Operando GIWAXS confirms suppressed microstrain and lattice distortion, demonstrating that synergistic

Mechanochemical Engineered Sulfur Copolymers Onto Group 13 and Related Fillers Through Lewis Acid‐Base Pairing

open access: yesAdvanced Science, EarlyView.
Green mechanochemical copolymerization was developed for universal interfacial modification of Group 13 and related fillers. By leveraging Lewis acid–base coordination to anchor sulfur‐containing polymers—validated via multiscale characterization and DFT—this versatile method boosts performance across liquid fuels, thermal‐shielding materials, and ...

Phase-field simulation of the thermomechanical processing of steels

open access: yes, 2013
A scheme has been developed to integrate the phase-field model with the homogeneous deformation. This has been applied to the simulation of the microstructure evolution during warm rolling of steels. The phase transition is characterized by the evolution

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

open access: yesAdvanced 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

An Environmental Stable Ionogel‐Based Smart Glove System for Integrated Underwater Communication and Safety Warning

open access: yesAdvanced Science, EarlyView.
This study develops a smart glove by integrating a P(BZMA‐co‐HEA)/IL ionogel with a reconfigurable FPCB for underwater communication and real‐time safety warning. The network‐constrained ionic soft‐space regulation strategy enables mechanical reliability, environmental stability, and sensing adaptability, while the modular FPCB sensor array simplifies ...
