Nitrogen and sulfur codoped carbon dots (CDs) were prepared from garlic by a hydrothermal method. The as-prepared CDs possess good water dispersibility, strong blue fluorescence emission with fluorescent quantum yield of 17.5%, excellent photo pH stabilities. It is also demonstrated that the are resistant to interference metal ions, biomolecules, high ionic strength environments. Combining low cytotoxicity properties, could be used as an probe for cellular multicolor imaging. Moreover,...

Research into new high-entropy alloys (HEAs) holds significant promise for advancing aerospace materials. Nevertheless, the complexity of their composition presents formidable challenges in designing HEAs with both high strength and plasticity. In this study, molecular dynamics (MD) simulation was used to explore optimal combination FeCoNiTi non-equiatomic ratios. Shear modulus (G) characterizes strength, while stacking fault energy (SFE) plasticity ductility. Through simulations, elastic...
Honeycomb‐like mesoporous pyrite FeS 2 microspheres, with diameters of 500–800 nm and pore sizes 25–30 nm, are synthesized by a simple solvothermal approach.

This study utilized first principles calculations to examine the interfacial bonding and thermodynamic properties of bcc-Fe/MeAl (where Me represents Ni, Ti, or Fe) interface. A total twelve distinct atomic stacking configurations were developed for bcc-Fe(110)/NiAl(110), bcc-Fe(110)/TiAl(100), bcc-Fe(110)/FeAl(110) interface structures. The analysis strength stability was conducted through calculation adhesion work energy. results indicate that T2N1 configuration at bcc-Fe(110)/NiAl(110)...
