“…The first oxidation peak, A 1 , at around –0.20 V, corresponds to the electroformation of a hydrous copper(I) oxide layer. [ 4,14,15 ] The second anodic peak, A 2 , at around 0.10 V, can be attributed to the formation of a copper(II) oxide. [ 14,15 ] At potentials more positive than 0.10 V, copper passes in a passive region, current density reaches a steady‐state value ( j pl ), and oxide film is becoming thick with increasing anodic potential.…”

The corrosion behavior of copper, tin, and bronze CuSn14 is studied in simulated acid rain (pH 4.5) by electrochemical techniques, cyclic voltammetry and electrochemical impedance spectroscopy. The potentiodynamic formation of anodic oxide film on copper and tin is described in terms of high‐field model. Cyclic voltammetry shows that dissolution of bronze is higher than of pure copper metal in acid rain. Electrochemical impedance spectroscopy data reveal that oxide films formed on copper and tin have a higher resistance and suppressed diffusion process through the surface layer than the oxide film formed on bronze CuSn14 at the same conditions.

“…They determined that water decoction not only retains antioxidant activity, but is also effective in wound healing, as it promotes tissue re-establishment after environmental stress exposure. Environmental topics continue to arise as Pilić and Martinović [ 79 ] investigated effect of H. italicum macerate on the corrosion of copper in simulated acid rain solution and Eksi et al [ 80 ] assessed H. italicum as a green roof substrate.…”

Helichrysum italicum is a Mediterranean plant with various pharmacological activities. Despite extensive reports on the bioactivity of the plant, its clinically studied applications have not yet been reviewed. The aim of our study was to gather information on the internal use of H. italicum and its bioactive constituents to determine its efficacy and safety for human use. We reviewed research articles that have not been previously presented in this context and analyzed relevant clinical studies with H. italicum. Cochranelibrary.com revealed six eligible clinical trials with H. italicum that examined indications for pain management, cough, and mental exhaustion. Although the efficacy of H. italicum has been demonstrated both in in vitro tests and in humans, it is difficult to attribute results from clinical trials to H. italicum alone, as it has usually not been tested as the sole component. On the other hand, clinical trials provide positive information on the safety profile since no adverse effects have been reported. We conclude that H. italicum is safe to use internally, while new clinical studies with H. italicum as a single component are needed to prove its efficacy. Based on the recent trend in H. italicum research, further studies are to be expected.

The antibiotic Ciprofloxacin (CIPRO) was investigated as a new inhibitor for copper corrosion in Synthetic Acid Rain Solution (SAR) utilizing Mass Loss (ML) as a chemical method, Potentiodynamic Polarization (PDP), and Electrochemical Impedance Spectroscopy (EIS) as electrochemical techniques. In the presence of 600 ppm of the antibiotic CIPRO, the protection percentage reached 90.1% according to the EIS technique. Thermodynamic adsorption and activation characteristics were evaluated and described. The CIPRO adsorption on the Cu surface in the SAR solution was physical adsorption and complied with the Langmuir isotherm. According to PDP curves, the studied medication was served as a mixed type of inhibitor. This medication prevented corrosion by adhering to the metallic surface, which was demonstrated by Atomic Force Microscopy (AFM), Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM–EDX), and Fourier-Transform Infrared Spectroscopy (FTIR). Results from the Density Functional Theory (DFT) and Monte Carlo simulations (MC) complement experimental results. The inhibition efficiencies obtained via different methods are consistent with each other. Graphical Abstract
