Self-healing of concrete cracks by the release of embedded water repellent agents and corrosion inhibitors to reduce the risk for reinforcement corrosion [PDF]

, 2017
From the worldwide steel production, approximately 50 per cent is required to replace corroded steel [1]. In the case of reinforced concrete structures, corrosion of the reinforcement steel causes crack formation and spalling which leads to ...

Efficient NiOx Hole Transport Layers Enabled by Multifunctional MXenes for High‐Performance Tin‐Lead Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
An efficient NiOx HTL is successfully prepared by introducing MXene as an additive without further surface modification to fabricate high‐performance FASn0.5Pb0.5I3 perovskite solar cells. The introduction of MXene contributes to improved conductivity of NiOx, better aligned at NiOx/perovskite interfaces, and enhanced quality of perovskite films ...

Effect of Al content on the corrosion behavior and mechanism of AlxCoCrFeNi high-entropy alloys

Journal of Materials Research and Technology
Al addition is known to improve the tensile strength and high-temperature oxidation behavior of the AlxCoCrFeNi high-entropy alloy (HEA). However, the corrosion behavior and mechanisms associated with these HEAs remain unclear.

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

Advanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Through Diamond Robust Surface Enhanced Raman Spectroscopy

Advanced Functional Materials, EarlyView.
Thin film diamond growth offers a unique opportunity for Surface Enhanced Raman Spectroscopy (SERS); the encapsulation of plasmonic nanostructures within a transparent, chemically stable, and physically robust coating. The diamond acts as both a window and protective layer, enabling illumination of the plasmonic nanostructures through the diamond ...

Localized High‐Concentration Electrolyte with Water‐Miscible Diluent Enables Stable Zinc Deposition and Long‐Life Aqueous Zinc Metal Batteries

Advanced Functional Materials, EarlyView.
A diisopropyl ether (DIPE)‐based, localized, high‐concentration electrolyte is developed to stabilize both electrodes in aqueous zinc batteries. By reducing water activity and promoting anion‐rich zinc‐ion solvation, it builds robust interphases at both the cathode and anode, ensuring uniform deposition, suppressed corrosion, and highly reversible ...
