Eco-friendly, renewable, and green polymers are getting a solution to challenge a major crisis occurring due to the limitation of fossil-based sources in the world. This work focuses on the development of alternative biobased and sustainable materials that are brought about by bifunctional and environmentally friendly biobased coatings. We reported that they are obtained by aza-Michael reactions that are established between acrylated soybean oils and biobased amines in the scope of click chemistry without the use of any catalyst, solvent, or required hightemperature conditions. The performance of the obtained coatings was investigated for comparison with reacted bifunctional aminemodified siloxane agents (NAPTMS, APTES, and NH2-CO). Coatings are obtained by curing acrylated epoxide soybean oil with various amine functional groups via an aza-Michael reaction by filming and spraying methods with one-and two-step approaches. NAPTMS, APTES, and NH2-CO demonstrate some kinds of effects in comparison to the base coating. To develop a water repellent, nanosilica particles (NSPs) are sprayed on the top coating, providing surface modification. Surface wettability showed that the water contact angle reached up to about 167 °C. It is also essential to consider that the superhydrophobic biobased systems have potential for repellency against different types of liquids such as water-based paint, coffee, tea, and methylene blue. The adhesion properties of the coatings improved from 1B to 5B. The prepared film layer is also provided to progress the rust along the scratched line and not be seen on the coated side, which shows a corrosive resistance impact. The resulting coating possessed an improved biocontent and a high elasticity level. Maximum elasticity was achieved in 12 s. It is expressed that the authors believe that this approach has potential as an economical way in textiles and other industrial applications.

“…The adsorption of asphaltene as a heavyweight polar portion of crude oil onto reservoir rock and surface facilities brings about severe challenges in oil recovery, production, transportation, and processing. [ 1–4 ] The negative effects of deposition and precipitation of asphaltene overshadow both upstream and downstream in terms of reservoir rock wettability reversal, [ 5–8 ] stabilizing oil–water emulsion, [ 9–11 ] blockage of the flow path, [ 12,13 ] and imposing extra costs at different stages of oil extraction by using various methods to inhibit, [ 14,15 ] mitigate, [ 16,17 ] or remove asphaltene.

Prediction of asphaltene adsorption capacity of clay minerals using machine learning

A thorough understanding of asphaltene adsorption on clay minerals is particularly important in oil production and contaminated soil remediation using claybased adsorbents. In this paper, we introduced a machine learning approach as a reliable alternative for commonly used adsorption isotherms that suffer from inherent limitations in the prediction of asphaltene adsorption onto clay minerals. Machine learning (ML) models, namely multilayer perceptron (MLP), support vector machine (SVM), decision tree (DT), random forest (RF), and committee machine intelligent system (CMIS) combined with two optimizers were used. Experimental data (142 data points for six different clay minerals) was used for the modelling. To improve the accuracy of the smart models, a comprehensive data preparation such as outlier removal and feature selection was carried out. The results showed that relatively all the proposed models predict asphaltene adsorption on clay minerals with acceptable precision. Nevertheless, the MLP model showed superior performance compared with other models in which the overall root mean square error (RMSE) and coefficient of determination (R 2 ) values of 6.72 and 0.93 were obtained, respectively. Finally, the developed MLP model was compared with the well-known adsorption isotherms of Langmuir and Freundlich and exhibited superior performance.
