“…Acceptable error statistics are produced for the construct. In accordance with Ren et al (2021) and Zhang et al (2021), it was found that superhydrophobic coatings can reduce the danger of oil spills, which is one of the significant advantages of oil spill management, and this uniquely identifies the possible success factor of superhydrophobic coatings in the oil and gas industry [29,30]. It has a significant impact on utilizing superhydrophobic coatings, as it can ultimately maximize oil spill management efficiency.…”

“…The mechanical characteristics of superhydrophobic coatings have also been discovered to strongly depend on the material employed. Ren et al (2021) examined the self-cleaning capabilities of superhydrophobic coatings and discovered that they are very efficient in removing dirt, oil, and other surface pollutants [30]. Rezaei et al (2019) examined the electrical conductivity of superhydrophobic coatings and discovered that they were very conducive and their electrical conductivity greatly depended on the material utilized in their production [31].…”

In the oil and gas construction industry, the adoption of superhydrophobic coatings is still in the early adoption phase. Due to the lack of research and the importance of hydrophobic coatings in the oil and gas construction business, this study examined the success determinants of superhydrophobic coatings in Malaysia. This quantitative study included a pilot survey to assess questionnaire validity and Exploratory Factor Analysis (EFA) to reduce success variables discovered through a literature review. A structural equation modeling (SEM) approach was used to develop a model involving success factors of superhydrophobic coatings in the oil and gas construction industry of Malaysia. Four constructs in total were found in SEM, namely, performance success, sustainability construct, oil spill management, and safety and economic success. In total, five items were excluded from the model because their loading factors were less than 0.6. All Cronbach Alpha reliability constants were greater than 0.7, the composite reliability indicators were greater than 0.8, and the AVE was greater than 0.6 for all of the constructs, confirming acceptable reliability and validity statistics. Both convergent and discriminant validity confirmed the relationships between all constructs and the latent variable. The observed path coefficients between the constructs and the latent variable were 0.476 for performance success, 0.461 for sustainability success, 0.322 for oil spill management, and 0.242 for safety and economic success. The significance value for all of the constructs was less than 0.05, confirming the strong relationship between the constructs and the critical success of superhydrophobic coatings in the oil and gas industry.

“…The fact that concrete is one of the most preferred construction materials was reflected by the global production volume of cement, which was around 4,1 billion metric tons in 2022 [1]. Its high stiffness and compressional strength, ease of production, and availability of raw materials make concrete a favorable material for buildings [2][3][4]. On the other hand, highly brittle characteristics of concrete can lead to crack formation at any time during its service life [5,6].…”

Concrete is commonly used as a supporting material in the construction industry. Although it can withstand heavy loads, it is very brittle and sensitive to crack formation. Earthquakes and other environmental factors may result in the formation of cracks in the concrete structure. Penetration of chloride and atmospheric water with dissolved oxygen and carbon dioxide gasses through these cracks leads to corrosion of rebar (reinforcing steel bars). This paper is a short review of polymeric structures as concrete healing materials.

“…Enhancement of wetting properties can provide lubrication and help to reduce wear and friction [1], intensify heat removal in cooling systems [2], increase the efficiency of collecting water droplets in the chamber of droplet catchers [3], etc. This is possible by applying a coating to a previously prepared surface or modifying the surface to obtain unique functional properties (e.g., corrosion-resistant, anti-icing, superhydrophobic, and self-cleaning [4][5][6][7][8]) by different methods, such as plasma spraying [9], chemical vapor deposition [10], laser irradiation [11], etching [12], and different polishing methods [13]. In contrast to methods for processing parts of equipment with a predictable surface relief, e.g., lithography, mechanical and thermal processing of metals and alloys often leads to uncontrolled changes in their surface properties.…”

Effect of mechanical polishing of aluminum alloy surfaces on wetting and droplet evaporation at constant and cyclically varying pressure in the chamber

et al. 2021

Improving the mechanical polishing of engineering surfaces in terms of the wetting and droplet evaporation theories is important for increasing the efficiency of modern equipment. Depending on the function of engineering surfaces, the mechanical polishing allows changing the wetting, as well as the liquid droplet evaporation rates and modes. However, the prediction of the processes occurring at the liquid/gas/solid contact line becomes more complicated after modification of metal surfaces, as well as under changing the environmental conditions. This work focuses on the study of wetting and evaporation of liquid droplets from polished aluminum alloy surfaces at constant and cyclically varying pressure. Wetting and droplet evaporation are key processes in equipment of the thermal power industry, in particular, operating at constant and cyclically varying high pressure: water-water steam generators, water vapor separators, droplet catchers, etc. Therefore, we investigated droplet wetting and evaporation modes after mechanical processes of surfaces, including polishing by tumbling, satin finishing, grinding and polishing by disks and pastes. We determined the condition when polishing of aluminum alloy surfaces by these methods does not affect the wettability by liquid droplets. Moreover, we established the effect of constant and cyclically varying high pressure on the droplet evaporation rate and evaporation modes. The pressure was found not to affect the characteristics of water droplet evaporation under conditions of periodically varied pressure in the chamber from the atmospheric (0.1 MPa) to high (0.5, 1.0, 1.5, and 2.0 MPa) values.
