Methylene blue (MB) dye is considered a well-known dye in many industries and the low concentration of MB is considered very polluted for all environment if it discharged without any treatment. For that reason, many researchers used advanced technologies for removing MB such as the electrochemical methods that considered very simple and give rapid response. Considering these aspects, a novel quartz crystal microbalance nanosensors based on different concentrations of PVC@SiO were designed for real-time adsorption of MB dye in the aqueous streams at different pHs and different temperatures.

AC corrosion represents a chronic issue that is faced by the buried metallic pipelines that are neighboring by the high voltage overhead transmission lines (HVOHTLs). In this paper a potassium hydroxide polarization cell (KOH-PC) is employed on the pipeline to mitigate the generated voltage from the power lines' intrusion with the buried pipeline. This work further investigates an integrated system to exploit the discharged energy for compensating the cathodic protection disturbances where a portion of this energy may be converted to DC form and reapplied on the pipeline as a cathodic protection voltage.

The problem of AC corrosion remains motivating for researchers because many factors influence the corrosion rate for buried pipelines due to the interference with overhead high voltage transmission lines (OHVTLs). Many researchers study the mechanisms of induced alternating current (AC) voltages, which are summarized as capacitive, inductive, and conductive coupling. In this work, only the induced AC voltage on the pipelines due to inductive coupling in steady-state conditions is studied.

This paper presents a novel contribution of a low complexity control scheme for voltage control of a dynamic voltage restorer (DVR). The scheme proposed utilizes an error-driven proportional-integral-derivative (PID) controller to guarantee better power quality performance in terms of voltage enhancement and stabilization of the buses, energy efficient utilization, and harmonic distortion reduction in a distribution network. This method maintains the load voltage close to or equal to the nominal value in terms of various voltage disturbances such as balanced and unbalanced sag/swell, voltage imbalance, notching, different fault conditions as well as power system harmonic distortion.
