Hierarchical Primary‐Secondary Coordination Synchronizes Ion Flux and Sulfur Redox in Solid Polymer Electrolytes

Advanced Functional Materials, EarlyView.
Hierarchical coordination engineering redistributes Li+ from anion‐dominated pairing toward polymer‐mediated binding. Strong primary sites promote salt dissociation, while distributed secondary sites sustain dynamic hopping pathways. This coordination landscape couples ion flux with polysulfide conversion, suppresses transport‐conversion decoupling ...

Concrete affected by multi-modal exposure of CO2 curing and alkali silica reaction (ASR)

Discover Concrete and Cement
In the past decades the ability to create durable, and sustainable concrete has largely been achievable thanks to the relative abundance, and regional availability of supplementary cementing materials (SCMs). SCMs are widely recognized to reduce and even

Multifunctional Solid Polymer Electrolyte Films Integrating Intrinsic Self‐Healing and Dual Photo‐/pH‐Responsive Ionic Sensing for Intelligent Flexible Electronics

Advanced Functional Materials, EarlyView.
Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

Review on Accelerated Carbonation on the Properties of Concrete

International Journal of Engineering and Advanced Technology, 2021
Concrete is an essential material in all constructions throughout the world. It has lot of uses in our daily routine life. Every material has to deteriorate and damage due to many factors in the same way the concrete also deteriorates. The carbonation process is identified as a main reason for the corrosion in reinforcement concrete structure.

Chemical Control of Space Charge Barriers and Grain Boundary Resistances in Polycrystalline Ionic Conductors

Advanced Functional Materials, EarlyView.
Grain boundaries (GBs) in polycrystalline materials often block charge transport and drive degradation. Using Gd‐doped CeO2 as a model electrolyte used in fuel/electrolysis cells, we developed a core‐shell infiltration method to selectively modify GB chemistry and space charge potential, achieving orders‐of‐magnitude ionic conductivity changes.
