“…When the number of EO units in a surfactant increased to a certain amount, the micelle concentration was higher, and the number of molecules needed was larger, so each micelle contained more molecules. 41 Surfactants that have more EO, that is, the hydrophilic end of the molecule is longer, may form a coil or interact with other molecules to form a coil in the pesticide solution, 42 which means that they cannot adsorb (or only adsorb weakly) on powdery mildew spores. The ability of the surfactant with EO number 3 to adsorb on powdery mildew pathogens was between those of AEO-4 (AEO-5) and AEO-7 (AEO-9).…”

Hydrophobic surfaces modified by pathogens in agricultural production are one of the main reasons to reduce the utilization of pesticides. Adding surfactants to pesticide solutions is a common method to improve their wetting and spreading properties. In this work, the interaction mechanism between pathogen-modified hydrophobic surfaces and mixtures of surfactants and a pesticide was studied in detail. The interaction mechanism was determined by characterizing the wetting and spreading behaviors of droplets on cucumber powdery mildew leaves at different growth stages. When surfactants were added, droplets on cucumber powdery mildew leaves were in the Wenzel wetting state, the pinning force weakened, the contact line speed accelerated, and the adhesion force increased. We explained the micellar state and aggregation behavior of surfactant molecules in a pesticide solution that was applied to the surface of cucumber powdery mildew leaves. Droplets of solutions containing nonionic surfactants easily formed semibald micelles, binding to the pathogen of powdery mildew, whereas droplets containing cationic surfactants did not do so. Because of the electrostatic interaction between cationic surfactant molecules and powdery mildew pathogens, cationic surfactant molecules did not wet the pathogens very well, so we suggest adding nonionic surfactants rather than cationic surfactants to improve the wetting and spreading of pesticide solutions on cucumber powdery mildew leaves. This study provides new insights into enhancing the wetting and deposition of droplets on pathogen-modified hydrophobic surfaces.

“…Sodium dodecylbenzene sulfonate (SDBS), an anionic surfactant widely employed in detergent production, oil recovery, painting, and various industrial applications [25,26], is noteworthy. Enhanced oil recovery (EOR) in particular represents a well-known technology utilizing SDBS to address the global demand for energy resources [27,28]. Despite its widespread usage, little attention has been directed towards assessing the environmental toxicity associated with the extensive utilization of SDBS.…”

Assessing oxidation–reduction potential (ORP) is of paramount importance in the efficient management of wastewater within both chemical and biological treatment processes. However, despite its critical role, insufficient information exists about how reactive chemical species generated by cold plasma (CP) in chemical treatment are associated with ORP and air flow rate. Therefore, we aim to identify the correlation between ORP and the removal of organic pollutants when using CP treatment. Additionally, we introduce a machine-learning-based operation to predict removal efficiency in the CP process. Results reveal a significant correlation of over 0.9 between real-time ORP and total organic carbon (TOC), which underscores the efficacy of ORP as a key parameter. This approach made it possible to control OH radical generation by regulating the air flow rate of the CP. This study posits that smart management facilitated by machine learning has the potential to enhance the economic viability of CP feasibility while maintaining overall treatment performance.

“…A surfactant's molecular structure is composed of two parts: the group that has no attraction effect with the solvent molecule is called the hydrophobic group, and the group with a strong attraction to the solvent molecule is called the hydrophilic group [1][2][3][4]. According to the properties of the main groups of surfactants, they can be divided into four categories: cationic surfactants, anionic surfactants, nonionic surfactants and zwitterionic surfactants [5][6][7]. The presence of a surfactant in water can significantly reduce the surface tension of the water, and it improve the surface activity of a solution, depending on its unique molecular structure.…”

In order to study the effect of inorganic salt additives on the surface tension of a sodium dodecylbenzene sulfonate (SDBS) solution, the surface tension of the mixed system of six common inorganic salt additives, NaCl, CaCl2, AlCl3, Na2SO4, Na2CO3, and NaHCO3, and SDBS was measured, and the effects of the inorganic salt types, surfactant concentrations and inorganic salt concentrations on the surface tension of the SDBS solution were studied. On this basis, three inorganic salts, NaCl, CaCl2 and Na2SO4, were selected, and their effects on the critical micelle concentration (CMC) of the SDBS solution were studied. The experimental results showed that different inorganic salts had different effects on the surface tension of the SDBS solution. The order of effect of the six inorganic salts on the surface tension of the SDBS solution was CaCl2 > NaCl > Na2SO4 > NaHCO3 > Na2CO3 > AlCl3; when the mass fraction of the SDBS solution is high, the influence of the inorganic salts on the surface tension of the SDBS solution is relatively small; with an increase in the concentration of the preferred inorganic salt additives, the surface tension of the SDBS solution decreases first, then tends to be stable, and then increases; a reduction in the critical micelle concentration by the three selected inorganic salt additives shows the trend of 0.7% NaCl > 0.5% CaCl2 > 0.5% Na2SO4.
