Abstract:
... Dual-phase steels are commercially attractive since they offer good formability at a high strength and reasonable cost. In addition to high strength, these steels also exhibit high “n-values” and high uniform and total tensile elongations. However, one limitation in the application of high-strength dual-phase steels is the fairly limited ductility observed during sheared-edge stretching or punched ...

Abstract:
... Two-dimensional (2D) graphitic carbon nitride (g-C₃N₄) nanoplates (CNNP) have become a hot research topic in photocatalysis due to their small thickness and large specific surface area that favors charge transport and catalytic surface reactions. However, the wide application of 2D g-C₃N₄ nanoplates prepared by ordinary methods suffers from increased band gaps with a poor solar harvesting capabili ...
