Summary: The study found that the Cu2O buffer layer can improve the surface quality and crystallinity of the Cu2O-Ag composite films, while an increase in the thickness of the silver layer results in increased absorption intensity and a shift towards the near-infrared region in the spectrum. Raman scattering experiments showed a significant increase in the scattering intensity of the composite films, and FDTD simulations confirmed the electric field enhancement characteristics of the composite structure.

Summary: Strategies for controlling anisotropic metal nanostructures have been developed for their potential in surface-enhanced Raman scattering (SERS) sensing. Silver substrates have been shown to be powerful tools for trace chemical analysis. In this work, star-shaped silver nanostructures were synthesized and used as SERS substrates for the detection of neonicotinoid pesticides. These substrates showed good reproducibility, reusability, and stability in SERS enhancement, enabling detection at low concentrations. The distribution of these nanostructures on the surface allowed for excellent reproducibility of the detection with a low relative standard derivation (RSD) of SERS intensity of 8%. This work establishes a platform for ultrasensitive detection of pollutants at very low levels without extensive pre-processing.

Summary: In this study, three-dimensional Ag aerogel-supported Hg single-atom catalysts were used as an efficient SERS substrate for monitoring enhanced oxidase-like reactions. The effect of Hg2+ concentrations on the SERS properties of 3D Hg/Ag aerogel networks was investigated, and an optimized addition of Hg2+ resulted in specific enhancement. The formation of Ag-supported Hg SACs was confirmed using HAADF-STEM imaging and XPS measurement, and the oxidase-like catalytic mechanism of Hg/Ag SACs was revealed using DFT. This research provides a mild synthetic strategy for fabricating Ag aerogel-supported Hg single atoms with promising prospects in various catalytic fields.

Summary: Plasmonic nanostructures, particularly irregular surfaces of silver nanorings, have shown promise in surface-enhanced Raman scattering (SERS) spectroscopy. Through the fabrication and characterization of clusters-based Ag nanorings, it was found that they could achieve SERS enhancement factors as high as 2.1 x 10^4.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
