The current study examines the evaluation of diazene-based Schiff base derivatives, namely, 4-((E)-(3-((E)-(hexylimino)methyl)-4-hydroxyphenyl)diazenyl)benzonitrile (S1) and 4-((E)-(3-((E)-(dodecylimino) methyl)-4-hydroxyphenyl)diazenyl)benzonitrile (S2). The structure elucidation of prepared the Schiff base compounds was performed by FTIR, 1 H NMR, and 13C NMR. In addition, the corrosion inhibition capacity of these compounds was investigated for API X65 steel pipelines in 1 M HCl utilizing gravimetric and electrochemical methods. By conducting the experimental investigations at various doses, it was possible to assess the inhibition effectiveness and adsorption behavior of S1 and S2. With increasing concentration, both inhibitors became more effective at inhibiting corrosion. S1 and S2 suppressed both cathodic and anodic processes, as shown by the potentiodynamic polarization study. The charge transfer resistance (R ct ) increased when S1 and S2 concentrations increased, according to the electrochemical impedance analysis (EIS) data. According to the Langmuir isotherm model, the adsorption of S1 and S2 inhibitors on carbon steel was discovered based on gravimetric measurements. The results were confirmed by theoretical data in addition to the experimental tests for the presence of S1 and S2 inhibitor films over the API X65 carbon steel surface.

“…Therefore, the risk-oriented approach is the most effective tool for ensuring the activity of the enterprise. It should be noted that the use of a risk-oriented approach is quite wide, namely, in the processes of ensuring the reliability of products [11], ensuring the sustainability of products on the market [12][13][14][15][16], the functioning of quality management processes [17,18], assessing the risks of the product life cycle [19], using renewable energy resources, smart technologies in the conditions of climate change [20,21,22], managing supply chains [23][24][25], managing the technical condition of objects [26][27][28].…”

The effective activity of road transport enterprises depends on the chosen strategy of enterprise management. The urgent role is the effectiveness of the use of a risk-oriented approach to the management and planning of the enterprise. The article, using the method of hierarchy analysis and probabilistic method, identifies and determines the contribution of risks. The factors that form the risks of road transport enterprises’ activities are defined for these types of enterprises. It has been found that the application of the hierarchy analysis method is a more time-consuming process and provides a deeper analysis of each risk. The probabilistic method is easier to apply, but it requires a high qualification of experts who will assess the risks. The results of surveys conducted by road transport enterprises indicate the application of elements of a risk-oriented approach. The availability of risk information makes it possible to implement appropriate precautions not only within an individual enterprise, but also on a more global scale.

Chasew leaves extract has been investigated as green corrosion inhibitor to inhibit the corrosion process of API 5L X52 in acidic media. The inhibition effect of cashew leaves was analyzed using electrochemical measurement such as Tafel Polarization and Electrochemical Impedance Spectroscopy (EIS). FTIR, polyphenol content and phytochemical analysis were also employed to ensure the chemical compound of cashew leaves extract. Concentration of cashew leaves extract was varied for electrochemical measurement i.e. 0, 100, 200, 300, 400 and 500 ppm. Furthermore, immersion time variation (0, 30 and 60 min) was used prior to electrochemical measurement. The electrochemical measurement results indicate that cashew leaves extract work effectively as green corrosion inhibitor of API 5L X52 in acidic media. The performance of this green corrosion inhibitor was optimum at concentration of 500 ppm and 60 min of immersion time. Cashew leaves extract was mixed-type inhibitor because the corrosion potential value shifted less than 85 mV. The Increasing of surface resistance value and the decreasing in the capacitance of double layer due to the adsorption process of cashew leaves extract molecules on the API 5L X52 steel surface. HIGHLIGHTS Cashew (Anacardium Occidentale) leaves extract as green corrosion inhibitor is a novelty of this research Cashew leaves extract delivers up to 96 % inhibition efficiency with 500 ppm of concentration and 60 min of immersion time ElS has confirmed that cashew leaves extract inhibits the corrosion process of API 5L X52 in acidic media by boosting the impedance Cashew leaves extract contains active corrosion inhibiting agents such as polyphenol, tannin, flavonoid and alkaloid The adsorption mechanism of cashew leaves extract obeys the Langmuir isotherm GRAPHICAL ABSTRACT
