Summary: Mo-Ag-Cu-Co films were fabricated by co-sputtering Ag/Mo and Co/Cu composite targets. The number, size and components of self-grown particles on the surface of Mo-Ag-Cu-Co films can be adjusted and controlled by changing annealing temperatures. The differences in diffusion of Ag, Cu, Co and Mo in the films play a major role in forming nanoparticles with different components. The monodispersed Ag particles and Ag-Cu particles were obtained on alloy films by magnetron sputtering for the first time without any template, and they exhibited excellent SERS performance.

Summary: Colloidal silver nanoparticles synthesized using Ganoderma lucidum extract are studied as a substrate for enhancement of SERS. The nanoparticles are nearly spherical with a mean size of 20-30 nm, as confirmed by SEM and DLS. The passivating layer on the nanoparticle surface is only a few nm thick, making these nanoparticles suitable for various applications involving plasmonic enhancement and charge or energy transfer.

Summary: Ag@C core-shell nanoparticles were prepared by a low-temperature heating-stirring method and subsequently modified with polyethyleneimine (PEI). Ag@C@Ag hybrid nanoparticles were then fabricated with 24-nm Ag NPs attached, demonstrating excellent optical properties for surface-enhanced Raman scattering (SERS) applications. Finite-difference time-domain simulations indicated that the signal enhancement was attributed to the Ag NPs, hot spots, and external assembly, allowing for ultrasensitive spectral analysis.

Summary: SERS substrates were synthesized using spherical silver nanoparticles adsorbed on Si substrate and opal of PMMA microspheres. Higher concentration of Ag-NPs in the composites led to alteration in the periodicity of PMMA opals and decreased intensity and broadened PBG. The performance evaluation using methylene blue as a probe molecule showed higher enhancement factor (EF) with increased Ag-NP concentration. The EFs of single Ag-NP were nearly 10-fold higher than those of Ag/PMMA composites possibly due to the porosity of PMMA microspheres and the metal-dielectric surface interaction.

Summary: In this study, a novel surface-enhanced Raman scattering (SERS) immunostructure utilizing Ag nanoparticle/porous carbon (Ag NP/PorC) films as the immunosubstrate and Ag nanocrystals (Ag NCs) as the immunoprobes is presented for ultralow level prostate-specific antigen (PSA) detection. The results demonstrate that the proposed SERS-type immunoassay is highly sensitive and selective to a wide range of PSA concentrations. Moreover, the method successfully detects PSA levels in human serum with a high consistency compared to the chemiluminescence method, with a recovery rate above 90%. Overall, this SERS-type immunoassay provides a promising method for the early diagnosis of prostate cancer.

Summary: Cu-Mo-Zr alloy films were prepared by magnetron sputtering, and a large number of Cu nanoparticles were spontaneously formed on the film surface. The quantity, size, and spacing of Cu nanoparticles were highly sensitive to annealing temperature, annealing time, Zr content, and film thickness. Coating an Ag layer on the alloy film significantly affected the size and spacing of Cu nanoparticles, and the synergistic effect between the Ag layer and Cu nanoparticles enhanced the local electric field. Using Ag layer/Cu-Mo-Zr alloy films as SERS substrates allowed the detection of low concentration of Rhodamine 6G solution.

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.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
