Ionic–Bionic Interfaces: Advancing Iontronic Strategies for Bioelectronic Sensing and Therapy

open access: yesAdvanced Science, EarlyView.
Ionic–bionic interfaces for bioelectronics leverage ions as multifunctional mediators that combine mechanical compliance, ionic and electronic functionalities, and therapeutic effects. These systems offer real‐time biosignal transduction, effective wound dressing, responsive drug delivery, and seamless interaction between soft tissues and electronic ...

WHAT'S SPACE GOT TO DO WITH IT? DISTANCE AND AGRICULTURAL PRODUCTIVITY BEFORE THE RAILWAY AGE [PDF]

open access: yes
This paper argues that the conventional Malthusian account of pre-modern economies as constrained by diminishing returns resulting from a fixed land supplied is flawed because it does not recognize the importance of systematic indivisibilities in the ...

Radical‐Mediated, Substrate‐Independent Fabrication of Hybrid Solid–Hydrogel Materials With Tunable Crosslinking: An Initiator‐ and Crosslinker‐Free Approach

open access: yesAdvanced Science, EarlyView.
This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.

Modification Strategies of Carbon‐Based Electrodes From Structural Regulation to Multifunctional Integration

open access: yesAdvanced Science, EarlyView.
Tracing the evolution from structural regulation to multifunctional integration, this paper systematically analyzes modification strategies for carbon‐based electrodes. It evaluates how element doping, surface functionalization, and composite material design affect the electrode performance, and offers perspectives on future applications and challenges

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy

open access: yesAdvanced Science, EarlyView.
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...

Engineering Charge Heterogeneity in COF/Graphene Hydrogels for Salt‐Resistant Solar Evaporation

open access: yesAdvanced Science, EarlyView.
Hetero‐charged COF/graphene hydrogel (HCG‐1) with spatially separated cationic and anionic domains is engineered to achieve salt‐resistant solar evaporation. This unique charge architecture regulates Na⁺ and Cl− distribution, promotes intermediate‐water formation and effectively suppresses salt crystallization, enabling stable solar evaporation in ...

The horizontal stratigraphy of a medieval hamlet - Mankby in Espoo, Finland [PDF]

open access: yes, 2015
The medieval hamlet Mankby in Espoo, Southern Finland, excavated from 2007–2013, has revealed a landscape that reflects the complex development of the region – from the initial Swedish colonization to the emergence of an established medieval village, a ...
