“…Notably, Zr/Nb-ZrO2 2 exhibited the smallest contact angle, indicating the highest hydrophilicity. Studies have shown a correlation between contact angle and surface roughness, where within a certain range, increased roughness corresponds to decreased contact angles [42]. This observation aligns with the AFM testing, which revealed that Zr/Nb-ZrO2 2 had the highest surface roughness.…”

Zirconium dioxide (ZrO2) possesses numerous advantages such as high mechanical strength, a low friction coefficient, excellent optical properties, and an extended lifespan. Consequently, ZrO2 has a broad research foundation and practical significance in functional films and wear-resistant coatings. However, it suffers from brittleness and low ductility when used as a bio-coating material. In this study, a ZrO2 film was fabricated on Si (100) and titanium alloy substrates using a magnetron sputtering system. Subsequently, Zr and Nb ions were implanted into the film at varying doses, but with consistent energy levels. The analysis focused on the film’s microstructure, mechanical properties, hydrophilicity, and corrosion resistance. The results demonstrate a significant improvement in the hydrophilicity and corrosion resistance of the ZrO2 film following the implantation of Zr and Nb ions. First-principles calculations based on density functional theory (DFT) principles indicated that, with increasing doping concentrations of Zr and Nb in the ZrO2 model, the stability of the model increased gradually, thereby enhancing its corrosion resistance. The developed product has propelled rapid advancements in fields such as biomedical implants.

“…The results show that the way antibacterial efficacy is enhanced depends on whether the experiment is done in the dark or under visible light. Previous studies [ 57,62 ] have shown that the percentage of inhibition of bacterial growth (IB%) in the absence of light can indicate both adsorption and self‐inhibition of E. coli . To obtain qualitative data for the detailed discussion purpose of results, the net visible light antibacterial efficacy (ΔIB%) value for each thin film is determined by subtracting the IB% under visible‐light exposure (IB% COMP‐Ag(visible) ) from the corresponding value obtained for each thin film under dark conditions (IB% COMP‐Ag(dark) ) as described by Equation .…”

To study the antibacterial efficacy of metallic Ag nanoparticle/titania (Ag‐NP)/TiO2 composite thin films against Escherichia coli (ATCC 25922), COMP‐Agn with various amounts of Ag (10 mol% ≤ n ≤ 80 mol%) are fabricated on a quartz glass substrate at 600 °C using the molecular precursor method. The films are characterized by X‐ray diffraction, X‐ray photoelectron, scanning electron microscopy, transmission electron microscopy, photoluminescence, and UVvis techniques. The analysis reveals that the films are composed of metallic Ag‐NPs embedded in a mixture of anatase and rutile matrix, with a volumetric fraction of Ag ranging from 0.18 to 0.68. The antibacterial activity of the TiO2 thin film and COMP‐Agn are determined by disk diffusion and viable cell count methods. Neither pure TiO2 nor pure Ag films exhibit any discernible antibacterial under dark and visible light. The antibacterial of Ag content in composite films is observed to persist for a maximum increase of 70%. The model is proposed on the basis of photoexcited electron transfer from Ag NPs to the TiO2 conduction band of COMP‐Agn, which clarifies the main factors affecting the photoresponse and the excellent response to visible light via surface plasmon resonance.
