Atomic‐Scale Insights Into Tramp Element Segregation and Mechanical Performance of a Low‐Carbon Steel

steel research international, EarlyView.
Despite increased hardness, elevated tramp element concentrations in a ferritic‐pearlitic low‐carbon steel lead to enhanced toughness accompanied by a more homogeneous and finer ferritic microstructure. Atom probe tomography reveals pronounced segregation of some tramp elements at grain boundaries and ferrite–cementite interfaces, together with ...

Hydrogen Reduction of Synthetic Fe2O3 Pellets: The Role of Calcium Oxide in Porosity Evolution and Reduction Kinetics

steel research international, EarlyView.
At 800 °C, hematite pellets containing 0.9 wt% CaO reduce in hydrogen at rates 1.2–1.4 times those of pure pellets. The inward‐moving reaction front supports a topochemical description, and FeO‐to‐Fe kinetics are consistent with mixed control by interfacial reaction and intrapellet diffusion.

Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

steel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...

Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

The Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...

Two‐Dimensional Materials For Lateral Flow Assays: A Critical Review of Functional Roles and Translational Challenges

VIEW, EarlyView.
2D nanosheets, with large surface area, excellent optical/electrical properties, and high specificity, combine with lateral flow assay strips to enable rapid, readable detection, boosting the strips’ development and applications. Abstract Lateral flow assays (LFAs) are widely used for point‐of‐care diagnostics, but their detection capability remains ...
