Regionally Localized Electrolyte Engineering via UV Crosslinking for Stable Ether–Carbonate Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
This work introduces a regionally localized electrolyte (RLE) that spatially separates ether‐ and carbonate‐based functions to stabilize both Li metal and high‐voltage cathodes. An immobilized ether‐rich layer directs Li+ transport, activates LiNO3 locally, and forms a uniform LiF‐rich SEI, enabling lower overpotential, uniform deposition, and long ...

Solvent‐Free Manufacturing of Multifunctional Gas Diffusion Electrode Architectures for Enhanced CO2 Conversion From Low‐Concentration Streams

Advanced Functional Materials, EarlyView.
A tandem gas diffusion electrode (GDE) leveraging hierarchically engineered microgranules enables efficient CO2 electroreduction under dilute CO2 conditions. A key innovation lies in the solvent‐free precision assembly of metal–organic‐frameworks, carbon nanotubes, and copper nanoparticles.

Fast Track to the Overdoped Regime of Superconducting YBa2Cu3O7‐δ Thin Films via Electrochemical Oxidation

Advanced Functional Materials, EarlyView.
Overdoping high temperature superconductors, such as YBa2Cu3O7‐δ (YBCO), is expected to maxime the critical current density by optimising the condensation energy for a given defect landscape, providing new thrust for the development of fusion enabling coated conductors. Here, precise oxygen control is achieved via an electrochemical method allowing for

Enhanced Endoscopic Internal Drainage of Gastric Abscess Through Additively Manufactured Stents

Advanced Healthcare Materials, EarlyView.
Postoperative gastric leaks are often treated with off‐label biliary double‐pigtail stents, yet conventional extruded designs are not optimized for leak anatomy, can migrate, and may limit abscess evacuation. PETALS is introduced to optimize transmural drainage geometry and enable patient‐specific 3D‐printable stents.

Diffusion of Macromolecules across the Nuclear Pore Complex

, 2007
Nuclear pore complexes (NPCs) are very selective filters that monitor the transport between the cytoplasm and the nucleoplasm. Two models have been suggested for the plug of the NPC. They are (i) it is a reversible hydrogel or (ii) it is a polymer brush.

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.
