“…As can be seen from Figure , the (111) and (200) diffraction lines for the NbC phase are clearly evident in the XRD spectra for both coatings, which are the two most common preferred orientations of textured materials with an fcc structure. − Clearly, the peak intensity ratio I (111) / I (200) is increased by the addition of Ag. From the formula reported in reference, the texture coefficient values (TC hkl ) of different crystal plane orientations for the two coatings can be calculated and are given in Table .…”

To mitigate the microbiologically influenced corrosion of metallic components serving in marine environments, an innovative Ag nanoparticle (AgNP)/NbC nanocomposite coating was synthesized using a double glow discharge plasma method. The coating was composed of Ag nanoparticles together with NbC nanocrystals embedded in an amorphous carbon (a-C) matrix. The incorporation of Ag into the NbC coating played a significant role in determining both the grain size and crystallographic texture of the NbC phase, as well as the bonding state of the carbon species and the surface morphology of the coating. Following immersion in sulfate-reducing bacteria (SRB)-inoculated artificial seawater, the planktonic SRB cell count for the AgNPs/NbC nanocomposite coating was found to be two and three orders of magnitude lower than those of the Ag-free NbC coating and bare Ti-6Al-4V, respectively. The electrochemical corrosion behavior of the AgNPs/NbC nanocomposite coating was evaluated and compared to the Ag-free NbC coating and bare Ti-6Al-4V in SRB-inoculated artificial seawater by using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The semiconducting properties of the oxide film grown on the nanocomposite coating were drawn from Mott–Schottky analysis. The results showed that Ag additions improved the microbiologically influenced corrosion (MIC) resistance of the NbC coating and led to the transformation of the electronic structure of the oxide film from an n-type semiconductor to a p–n heterojunction structure.

This work reports on Ti 1-x Ag x and Ag-TiN x electrodes deposited by dc/pulsed dc magnetron sputtering at room temperature on poly (vinylidene fluoride) (PVDF) with the purpose to develop sensors for prosthesis. In Ti 1-x Ag x electrodes, silver content was varied from 0-100 at. %; and for Ag-TiN x electrodes, the nitrogen content was varied between 34 to 43 at. % and the Ti/Ag ratio changed from 12.2 to 5.2. The antibacterial activity of the samples was show that Ag-TiN x electrodes are more promising candidates to be used in PVDF sensor protection than Ti 1-x Ag x electrodes.

“…Indeed, the atomic force microscope (AFM) image reveals that the surface particle height is only ∼50 nm (Figure S4). The reduced roughness of the AlN/Ag layer is mainly caused by the reduction of AlN grain size promoted by the amorphous phases and the Ag segregation. , The AlN/Ag coating was further characterized by transmission electron microscopy (TEM), which reveals that AlN/Ag is evenly coated onto Zn foil (Figure c). A more careful observation indicates that the Ag nanoparticles (10–30 nm) are uniformly distributed in the AlN matrix (Figure d).…”

Secondary aqueous zinc-ion batteries (ZIBs) are considered as one of the promising energy storage devices, but their widespread application is limited by the Zn dendrite issues. In this work, we propose a rational design of surface protective coatings to solve this problem. Specifically, a silver (Ag) nanoparticle embedded amorphous AlN matrix (AlN/Ag) protective layer is developed. The former would alloy in situ with Zn to form AgZn3 alloy sites, which subsequently induce the Zn deposition with preferred (002) facets. The latter can effectively alleviate the structural expansion during repeated Zn plating/stripping. Consequently, the delicately designed AlN/Ag@Zn anode delivers an enhanced stability with a long lifespan of more than 2600 h at 1 mA cm–2 and 1 mAh cm–2. Moreover, the AlN/Ag@Zn||Mn1.4V10O24·nH2O full batteries can be operated for over 8000 cycles under 5 A g–1. Our work not only suggests a promising Zn anode protective coating but also provides a general strategy for the rational design of surface protective layers for metal anodes.
