The growing threat of resistant bacterial infections is a global concern. Therefore, it is crucial to discover new antimicrobial agents or alternative mechanisms to address this issue. This article explores the potential of smart antimicrobial surfaces based on Schottky interfaces for mitigating bacterial infections. The article proposes combining the biological features of bacterial cells with the physics of Schottky-Mott theory to describe and explain the disinfection behaviors of Schottky interfaces. The physicochemical properties and associated characterization methods of Schottky interfaces are examined to uncover their smart pathways leading to disinfection. The fabrication of antimicrobial Schottky interfaces is explored, focusing on techniques such as sputtering, evaporation, chemical deposition, and ion implantation. The advantages and challenges of each method are highlighted, along with recent research on their use to create antimicrobial surfaces over different activating procedures, ranging from light adsorption to bacterial charging and capacitive charge storage. Overall, this article provides a comprehensive overview of the knowledge and advancements in smart antimicrobial surfaces based on Schottky interfaces, emphasizing their potential in combating bacterial infections and offering insights into their properties, fabrication, and applications. The article concludes by illuminating the need for additional research to completely understand the dark behaviors of Schottky interfaces against microbes and harness their full potential in smart coating developments. © 2025 The Authors

Physical Review B 2024年第8期110卷 085402-085402页

The phenomenon of oxygen adsorption induced surface restructuring is widespread across various metal-oxygen systems, yet its impact on initiating bulk oxide formation remains largely unexplored. Through in situ atomic-resolution electron microscopy observations of surface oxidation of Cu(110) and Cu85Au15(110), we unveil intermittent oxide-film growth modulated by oxygen-induced surface restructuring. This modulation is evidenced by repeated pinning of the Cu2O growth front at isolated Cu columns of the c(6×2)-O reconstruction, owing to required long-range diffusion of Cu and O atoms to the Cu2O growth front. We reveal that Cu vacancies, generated at the Cu2O growth front, are injected into the Cu2O/Cu interface, inducing hill and valley undulation of the Cu2O film. In contrast, atomic vacancies produced during the Cu85Au15(110) oxidation preferentially migrate into interfaces between Au-rich and Au-poor regions in the bulk, resulting in a flat and adherent Cu2O film. These findings demonstrate the critical role of oxygen-induced surface restructuring in modulating oxide film growth kinetics and the manipulability of the fate of injected vacancies by alloying, thereby offering insights applicable to a broader range of metal-oxygen systems for fine-tuning oxidation kinetics and enhancing oxide/metal interfacial adhesion.

Corrosion is a detrimental persistent industrial conundrum that can cause the failure of operating equipment and weakening of construction assemblies, thus threatening the lives of humans, and accelerating the consumption of the natural metals reservoirs. In this study, we deployed green silver nanoparticles (AgNPs) as corrosion inhibitors for mild steel. Citrus aurantium peels aqueous extract (CAPE) mediated the bio-reduction of silver ions (Ag+) into silver nanoparticles (AgNPs) under optimized experimental conditions. The prepared nanoparticles were comprehensively characterized by various techniques for size, morphology, optical properties, crystallinity, and elemental composition. Phytochemical analysis showed that the plant extract is rich in phenolic compounds that facilitated the formation of metallic silver from Ag+ ions. The anticorrosion properties of CAPE and CAPE-AgNPs for mild steel in 0.5 M HCl were investigated by potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The biosynthesized CAPE-AgNPs were more efficient than CAPE in slowing down corrosion with inhibition efficiency of 70% attained at 1000 ppm of the inhibitor. CAPE and CAPE-AgNPs acted as mixed-type corrosion inhibitors with dominance over the cathodic reaction. Fitting the experimental data into different isotherms demonstrated that the corrosion inhibition was an endothermic process that took place through physical adsorption. CAPE-AgNPs significantly reduced pitting and localized damage on the metal surface. These findings highlighted the utility of CAPE-AgNPs as efficient corrosion inhibitors in different industrial settings. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.
