Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

Advanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Water Organization and Hydration‐Dependent Hydroxide Transport in Anion Exchange Membranes (AEM)

Advanced Functional Materials, EarlyView.
Hydroxide transport in anion exchange membranes is governed by the organization of water within the polymer rather than by hydration alone. A hydration‐window framework is presented to unify transport, swelling, and mechanical stability, providing guidance for designing durable membranes for fuel cells and other hydroxide‐based electrochemical ...

Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport

Advanced Functional Materials, EarlyView.
Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.

Variation of the Chemical Composition of Waste Cooking Oils upon Bentonite Filtration

Resources, 2019
The chemical composition and the color of samples of waste cooking oils (WCOs) were determined prior to and after filtration on two different pads of bentonite differing in particle size.

Reconstructing Residual‐Solvent‐Involved Li+ Coordination in PVDF‐HFP Polymer Electrolytes for Stable Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
2,2,2‐trifluoroethanamide‐mediated coordination regulation reconstructs the local Li+ environment in PVDF‐HFP polymer electrolytes by weakening residual DMF‐dominated coordination and promoting TFSI−‐involved anion‐rich solvation. This strategy facilitates Li+ migration and interfacial desolvation, promotes the formation of a thin inorganic‐rich SEI ...

Programmable Soft Actuator with Multi‐Responsiveness Based on Conductive MOF‐Liquid Crystal Polymer Composite

Advanced Functional Materials, EarlyView.
A sequential dual‐alignment strategy independently programs the orientation of conductive metal‐organic framework (c‐MOF) microrods and liquid crystals within a composite film. This approach creates an asymmetric bilayer structure that enables precise, multi‐responsive actuation.

Pressure‐Assisted Dimensional Transformation of 2D Hydrogenated Borophene into 0D Boron Quantum Dots

Advanced Functional Materials, EarlyView.
Hydrogenated borophene (HB) is transformed into distinct boron nanostructures through a solvent‐free thermal process. Under flowing nitrogen, hydrogen escape promotes reconstruction into B2O3 nanoplatelets, whereas hydrogen‐induced pressure under sealed conditions facilitates fragmentation into boron quantum dots.
