Stepwise On‐Surface Synthesis and Transformations of Two‐Dimensional Covalent Organic Frameworks by Controlled Thermal Stimuli

open access: yesAdvanced Materials, EarlyView.
The seminal transformation of a 2D‐COF (SURFCOF‐IMDEA1) into a 2D porous COF (SURFCOF‐IMDEA2) on Au(111) by a sequential C‐C coupling and ladderization triggered by thermal annealing steps at increasing temperatures is reported. Abstract The development of covalent organic frameworks (COFs) is currently a primary objective in materials science, taking ...

Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons

open access: yesAdvanced Materials, EarlyView.
Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

High‐Concentration Antibody Formulation via Solvent‐Based Dehydration

open access: yesAdvanced Materials, EarlyView.
Amorphous solid antibodies are encapsulated into hydrogel microparticles through a solvent‐based dehydration process. The solvent extracts water from antibody solution droplets, causing the antibody to concentrate, and precipitation of the antibody into amorphous solid is induced.

Energy‐Efficient, Sustainable Cascade Glucose Electrooxidation into Glucaric Acid

open access: yesAdvanced Materials, EarlyView.
This study presents a tandem system that efficiently converts glucose into glucaric acid while generating renewable electricity. By decoupling the oxidation process into two cascaded steps, the system achieves an overall 90% Faradaic efficiency and 80% conversion efficiency at ∼0.6 VRHE, significantly reducing energy consumption compared to traditional

Fluctuating Curvature and Actuation in 4D Printed Asymmetric Networks by Frontal Photopolymerization

open access: yesAdvanced Materials Interfaces, EarlyView.
Asymmetric polymer networks, fabricated by frontal photopolymerization (FPP), are shown to exhibit curvature oscillations associated with monomer‐solvent exchanges during development and drying. We introduce a theoretical model for such dynamic curvature fluctuations and demonstrate the fabrication of bistable switches and self‐propelled materials that
