Corrosion‐Protection of T122 Steel Using g‐C3N5‐Embedded Epoxy Coatings
Materials and Corrosion, EarlyView.Study evaluates g‐C3N5 (CN) reinforced epoxy coatings on T122 steel in NaCl and H2SO4. Electrochemical tests revealed that 2% loading maximizes corrosion resistance by blocking pores and limiting ion diffusion, increasing Rp and Rn. Optimized CN content enhances epoxy coating performance overall system durability material. ABSTRACT Corrosion‐protection

Materials and Corrosion, EarlyView.Excellent corrosion resistance of commercial Al‐containing materials is shown for exposures to liquid lead (Pb) at 600°C. However, oxide scale failure occurs at 700°C. The formed oxide scales and their failure mechanisms are explored. ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid for advanced thermal energy storage (TES) systems.

Determination of the Magnetic Material Composition in Magnetite Ore and Processability Evaluation
Yankuang ceshi, 2013 Magnetite samples were magnetically separated with a magnetic tube and artificial magnetic separation. The contents of TFe, P, S, V2O5, TiO2, SiO2, Al2O3, CaO, MgO, Sn, Cu, Pb and Zn in the magnetite samples were determined.

Complexions at the iron-magnetite interface
Nature CommunicationsAbstract Synthesizing distinct phases and controlling crystalline defects are key concepts in materials design. These approaches are often decoupled, with the former grounded in equilibrium thermodynamics and the latter in nonequilibrium kinetics.

Materials and Corrosion, EarlyView.The present study generated the corrosion performance of C‐steel, zinc, and galvanized steel in different global unsaturated soil environments for 2 years. Acceptable matching was observed between corrosion rates and identified corrosion products. To properly predict soil corrosion, the results showed that DIN 50929 should include a drainage‐capability

Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media
Polymer International, EarlyView.Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...
