“…In this paper, the spectra have been fitted using a two‐cell EC like the one in Figure (b), to describe the impedance of the two interfaces: metal/rust layer and rust layer/electrolyte, respectively. However, a third time constant seems to appear at low frequencies, visible in the phase angle in Figure of reference (Figure ), which is neglected by authors and would require additional elements in the EC. This 3‐time constants spectra have also been reported in other works,, for which the aforementioned R(RC(C[RW])) model still seems the best match.…”

“…This has led to the latest design, a rigid plastic cell, made of ABS, with a polyurethane disk in the contact side to provide adaptability to “non‐perfectly flat and/or rough surfaces” (Figure ). The cell has an inner chamber with a platinum CE, and is filled with the electrolyte through an inlet tube …”

Protecting metallic cultural heritage from corrosion is a major challenge for metal conservators. Electrochemical techniques offer a great potential for monitoring the conservation condition of this type of heritage, providing a powerful tool for designing conservation strategies. For this reason, the application of techniques such as electrochemical impedance spectroscopy (EIS) has aroused increasing interest in recent years, although some difficulties in application and interpretation of the results still keep it from being routine practice. This Review aims to picture the state-of-the-art of using electrochemical impedance spectroscopy (EIS) for the in situ monitoring of metallic cultural heritage, focusing on spectra interpretation and different approaches that have been proposed to perform field measurements since the 1990's. In the first part of the Review, different cell designs based on the use of liquid or solid electrolytes for in situ measurements are reviewed. In the second part, a few general equivalent circuits are proposed as a basis for interpreting results on different metal surfaces after discussing different models proposed in literature. This overview intends to summarize and clarify the key points in the use of EIS, and encourage the use of this and other electrochemical techniques in the field of conservation science, for a better preservation of our cultural heritage.

In this paper, a new controller, management and security system (CMSS) was proposed to ensure the overall operation of pico-hydroelectric power plants (PHPPs) at low-cost, especially in off-grid sites in remote areas. The proposed system can be used to meet the requirements of the PHPP such as the start-up, the departures' management, the loadfrequency controller (LFC), the emergency stop (ES), and the normal stop procedures in order to guarantee good quality and sustainable services. The system was tested under various conditions to prove its reliability using PHPP prototype. Based on the prototype, the laboratory experimental results are presented. The design's details and the implementation of the system are given as well. The system is completely independent, and it achieved an initial cost of only 266 $. The flexibility makes the system more suitable for extended future improvement such as adding data-logger, adding communication aspects using wireless technologies, etc. Furthermore, the system could be easily adapted for different educational purposes, especially for universities with limited resources.
