“…Previously, LISSs were applied to various ceramic and metallic substrates, while in this study, austenitic stainless steel was chosen as a substrate due to its wide application in marine environments, owing to good corrosion resistance, easy formability, and excellent mechanical properties . The coating was applied on austenitic stainless steel of the AISI 316L grade, utilized in coastal service environments, splash zone applications, and submersion in seawater, to name but a few. , In this study, the stainless steel substrates were polished before being modified by LISS coating for better color contrast between the substrate and contaminating fouling species, while the same process can be equally applied to plain steel substrates.…”

Wetting of surfaces plays a vital role in many biological and industrial processes. There are several phenomena closely related to wetting such as biofouling and corrosion that cause the deterioration of materials, while the efforts to prevent the degradation of surface functionality have spread over several millennia. Antifouling coatings have been developed to prevent/delay both corrosion and biofouling, but the problems remain unsolved, influencing the everyday life of the modern society in terms of safety and expenses. In this study, liquid-infused slippery surfaces (LISSs), a recently developed nontoxic repellent technology, that is, a flat variation of omniphobic slippery liquid-infused porous surfaces (SLIPSs), were studied for their anti-corrosion and marine anti-biofouling characteristics on metallic substrates under damaged and plain undamaged conditions. Austenitic stainless steel was chosen as a model due to its wide application in aquatic environments. Our LISS coating effectively prevents biofouling adhesion and decays corrosion of metallic surfaces even if they are severely damaged. The mechanically robust LISS reported in this study significantly extends the SLIPS technology, prompting their application in the marine environment due to the synergy between the facile fabrication process, rapid binding kinetics, nontoxic, ecofriendly, and low-cost applied materials together with excellent repellent characteristics.

“…The presence of salts with retrograde solubility, where the saturation concentration decreases with higher temperatures, such as CaSO 4 , Ca(OH) 2 , and CaCO 3 , further exacerbates the problem. Because hypersaline brines almost always contain sparingly soluble salts, including retrograde solubility minerals, and often at concentrations greater than in seawater [186], scaling is a significant operational problem for MED and MSF.…”

“…Additionally, hypersaline streams are corrosive due to the high chloride concentration. This is especially problematic for distillation processes as the rate of corrosion increases strongly with temperature [20,[186][187][188]. At the same Cl − concentration, steel, for example, corrodes >100 times faster at 100 • C than at 60 • C [189].…”

“…316 L stainless steel has a low cost and acceptable resistance to distillate water. Compared with 304 L stainless steel, it has stronger resistance to pitting corrosion (Panagopoulos et al 2020). To investigate whether HCl had a corrosive effect on these two materials, corrosion tests for titanium and 316 L stainless steel were carried out.…”

In the mechanical vapor recompression (MVR) treatment of landfill leachate, scaling in the evaporator and heat exchanger poses a serious problem. This study explored the reasons for such scaling and proposed acid or ion-exchange pre-treatments to reduce the alkalinity of the landfill leachate nanofiltration concentrate (LLNC) to prevent scaling. The feasibility of these two methods was evaluated and the technical and economic parameters for application were obtained via experiments. A large amount of HCO3- in the LLNC was the main cause of scaling. The acid addition experiment and field application demonstrated that this method could prevent fouling problems. The cost of acid addition was USD 0.18/t. LLNC pre-treatment by ion-exchange showed that a weakly acidic cation-exchange resin performed better than a strongly acidic cation-exchange resin did. The amount of solid residue under an alkalinity of 0 mg/L could be decreased by 92.9% compared with that of raw LLNC during evaporation. Both methods could alleviate scaling and enable the wide application of the MVR evaporation process in landfill leachate treatment.
