“…The charge transport through the concrete bulk material is ensured by the saline composition of concrete . In this way, the porosity of paper and concrete matrix is exploited to establish the electrochemical contact between the paper‐based sensor and the concrete surface, avoiding the use of other intermediate materials such as sponges or gel electrolytes . This configuration turned out to be suitable for the measurement of the potential between the metallic bar embedded into the concrete and the printed electrode placed on the surface of the concrete itself.…”

“…The measuring sites were selected to ensure a proper clamping of the metallic component as well as a proper adhesion of the sensor on the concrete surface, avoiding inhomogeneous portions. It can be observed that the position of the sensor on the concrete surface with respect the reinforcement does not affect the potential recorded, as long as the sensor is placed nearby of the reinforcement, as showed in our previous work . In order to examine the possible differences of corrosion extent among the different levels of the artwork, three chairs were chosen from the bottom level and one chair was chosen from the second level (in Figure the chairs are numbered from 1 to 4).…”

“…All the concrete samples were prepared using the procedure reported in our previous work . In detail, Portland cement and river sand were mixed in a 1 : 2 (w/w) ratio, adding 150 mL of water per 1 kg.…”

“…Nevertheless, the study of the corrosion phenomena on buildings and artworks containing structural or ornamental metallic components has been carried out mainly in the laboratory, to avoid physical or chemical damages of the real artefacts . In our previous work, we have demonstrated the possibility to use an alternative electrochemical device, in which the bulk Cu/CuSO 4 electrode is replaced with a miniaturised screen‐printed Ag/AgCl pseudo‐reference electrode, while the wet sponge is replaced with a KCl‐containing agar gel . The experimental setup developed allowed for the evaluation of the corrosion conditions of the metallic reinforcements embedded into concrete samples prepared in the laboratory (lab‐prepared samples).…”

Herein, we present the first paper-based device for facing one of the worldwide concerns of the Modern age: the corrosioninduced deterioration of reinforced concrete. Indeed, the monitoring of corrosion extent in reinforced concrete constructions has been acknowledged as a priority for public safety. In this work, the porosity properties of a paper-based screenprinted Ag/AgCl electrode were exploited for realising a smart analytical tool to be directly applied on the solid surface of concrete for the evaluation of corrosion. The analysis was carried out by measuring the electrochemical potential between the metallic reinforcement and the sensor, needing only 70 μL of electrolyte solution. The sensor was firstly tested in the laboratory using reinforced concrete samples and then applied on the real outdoor artwork Music Collection Session by Arman (Milan, Italy). A summary of the main available nondestructive techniques for corrosion monitoring is reported to provide a critic overview.

Corrosion sensing is essential to monitor and safeguard the materials’ health and control the maintenance cost of corrosion-prone materials used in various industries. The petroleum industry is a major sufferer of corrosion costs among various industries due to pipelines and downhole applications. This review article encompasses an overview of various technologies used in early detection stages for more reliable corrosion sensing and warnings. This review provides a summary of corrosion types, corrosion causing chemical species, different destructive and non-destructive technologies used in monitoring corrosion and a comprehensive overview of the state-of-the-art of various electrochemical techniques used for surface and downhole corrosion monitoring. Finally, the existing challenges for corrosion monitoring in surface and downhole conditions and prospects are discussed.

The application of Mott–Schottky (M−S) analysis of impedance data to sub–micro samples extracted from the corrosion patina of copper, bronze, and brass archaeological artifacts attached to graphite electrodes is described. The corresponding theoretical approach is developed to account for the contribution of the composition and structure of the corrosion patina and the effect of the bare graphite substrate. Experimental data in contact with 0.10 M Na2SO4 aqueous solution at pH 6.28 are consistent with the p‐type semiconducting nature of the main copper corrosion products, cuprite, and tenorite. The values of the apparent flat band potential and the slope of the M−S plots allow archaeological samples to be grouped according to their M−S parameters (slopes and intercepts). Assuming equivalent conditions of corrosion, the resulting grouping is judged to be dependent on the composition, and/or method of manufacture, and/or age. Studied samples include Renaissance statues from the Hofkirche in Innsbruck and a variety of objects from museums and Archaeological Heritage Office (soprintendenza) in Austria (Bad Aussee, Johanneum Graz, and the Tyrolean State Museums), and Italy (Genoa and San Remo), dating from the Bronze Age to the 18th century. Complementary data are provided by voltammetry of immobilized particles.
