“…The n equals to 1 when it corresponds to a capacitor, it takes the values 0.5 < n < 1 when a non-ideal capacitor behavior takes place, n equals to 0.5 when the CPE describes a diffusion process and represents a Warburg impedance, and finally, n equals to 0 when it represents a resistor (Orazem and Tribollet, 2008;Zhu et al, 2016).…”

This study focuses on the design, development, and validation of two coating systems for corrosion protection of hot dip galvanized steel substrates. The coatings consist of epoxy-based resin reinforced with core-shell microcapsules, either cerium oxide or cuprous oxide core and a polymeric shell doped with cerium ions. The effect of the modification of the epoxy resin with a liquid rubber polymer has also been studied. Corrosion studies via electrochemical impedance spectroscopy (EIS) revealed that the coatings have enhanced barrier properties. Moreover, EIS studies on coatings with artificial scribes, demonstrated an autonomous response to damage and a selfhealing effect. Heat-induced material re-flow has also been observed after exposure to temperature higher than the T g of the system, which offered an additional self-healing mechanism, partially inhibiting the underlying corrosion processes when the liquid rubber is present in the system.

“…Organic corrosion inhibitors, especially surface-active agents (surfactants), have been reported to be some of the most effective inhibitors due to their ability to form self-assembled films at interfaces, as shown in Fig. 15 (Fuchs-Godec, 2009;Zhu et al, 2016;. These barrier layers inhibit the transport of corrosion, causing ionic species to and from the surface.…”

Particulate and surfactant systems are an integral part either in processing or product lines in essentially every major industry, including Energy and Minerals, Pharmaceutical, Agriculture & Food, Microelectronics, Healthcare, Cosmetics, Consumer Products, and Analytical Instrumentation & Services. In most applications, product and process specifications depend on the synergistic or competitive interactions between the particles and reagent schemes. The primary goal of our research efforts has been to generate the structure-property-performance correlations-based knowledge and technology platforms for industry to develop more sustainable products and processes. Engineering the physicochemical/mechanical properties of surfaces, particles, and self-assembling surfactant systems enables their enhanced performance in industrial applications. Specifically, understanding and control of the nano and atomicscale forces between particles and synthesis of functionalized particles form the foundation for targeted contributions in biomedical, advanced materials and minerals, sensor, and coating technologies. A synoptic overview of selected projects is presented in this review. Additional details can be found in the topic-specific references listed at the end of this manuscript.

“…The inhibition efficiency of a specific surfactant or surfactant class depends on molecular properties such as the charge of the head group (anionic, cationic, non-ionic, amphoteric) and the chain length of the nonpolar molecule part [15]. Further factors of influence are properties of the solution such as concentration of the surfactant, the pH value, and the presence of other ions, as well as environmental parameters such as temperature [16][17][18].…”

Peracetic acid (PAA) is a highly potent disinfectant, exhibiting an outstandingly broad spectrum of activity against various microorganisms and viruses. Nevertheless, one disadvantage when applying PAA for disinfection purposes is the strongly corrosive effect due to its oxidizing properties. The employment of a nonionic surfactant as corrosion inhibitor was evaluated in addition to adjustment of the pH value of the solution, regarding the materials aluminum, stainless steel, copper, brass, polyvinyl chloride, wood, and ceramics. Whereas unmodified PAA solution led to strong corrosive effects on the material surface, this impact was significantly lowered when the pH value was shifted to 7. When in addition a nonionic surfactant was applied, no corrosion phenomena at all were observed.
