“…Overall, the key benefit of using a thermodynamic approach is its usefulness in explaining generic like-to-like observations, such as bacteria with hydrophobic cell surfaces favor hydrophobic material surfaces while those with hydrophilic cell surfaces favor hydrophilic material surfaces (Krasowska and Sigler, 2014). Similarly, bacterial adhesion is often suitably described by DLVO and its derivative theories (Hwang et al, 2010(Hwang et al, , 2012Carniello et al, 2018;Zhang et al, 2019) since the size of most bacteria (0.5-2 µm) is close to the range of colloidal particles (Hori and Matsumoto, 2010). Briefly, the relative strengths of van der Waals and Coulomb interactions enable bacterial adhesion to surfaces depending on the bacterium-surface distance and ionic strength of the surrounding fluid.…”

Biofilms are structured microbial communities attached to surfaces, which play a significant role in the persistence of biofoulings in both medical and industrial settings. Bacteria in biofilms are mostly embedded in a complex matrix comprised of extracellular polymeric substances that provide mechanical stability and protection against environmental adversities. Once the biofilm is matured, it becomes extremely difficult to kill bacteria or mechanically remove biofilms from solid surfaces. Therefore, interrupting the bacterial surface sensing mechanism and subsequent initial binding process of bacteria to surfaces is essential to effectively prevent biofilm-associated problems. Noting that the process of bacterial adhesion is influenced by many factors, including material surface properties, this review summarizes recent works dedicated to understanding the influences of surface charge, surface wettability, roughness, topography, stiffness, and combination of properties on bacterial adhesion. This review also highlights other factors that are often neglected in bacterial adhesion studies such as bacterial motility and the effect of hydrodynamic flow. Lastly, the present review features recent innovations in nanotechnology-based antifouling systems to engineer new concepts of antibiofilm surfaces.

“…The degree of structuring depends on the hydrogen-donating and accepting properties of the surface (see also Figure 2) and decays after a layer thickness of around 1 nm, which corresponds with the size of small clusters of up to 5 water molecules in unbound water (Van Oss and Giese 2005; Bj€ orneholm et al 2016). Therewith, the acid-base character of the underlying surface determines the properties of the outermost surface of a bound water layer, directing the conformation of adsorbed proteins (Zhang et al 2020) and governing adhesion of bacteria (Zhang et al 2019;Cai et al 2021). The structure of water on hydrogen-donating and hydrogen-accepting surfaces depicted in Figure 2 excludes the role of ions.…”

“…Zou et al (2018) used the extended DLVO theory to explore the interfacial interaction between coal and the main impurity mineral particles in application of selective flocculation flotation. It has been shown that in the initial ash deposition stage, the length of the induction period depended on the energy barrier (Zhang et al 2019).…”

One of the largest problems with most current thermal power plants is the cooling efficiency. This paper aims to massively reduce fuel consumption and heat wasted in thermal power plants and hence CO2 emissions by resolving fouling issues associated with air-cooled condensers. In order to reduce the dust fouling deposition in the air-cooled condensers, the finned flat tubes were coated with nickel−phosphorus and nickel−phosphorus−polytetrafluoroethylene (Ni–P-PTFE) by an electroless coating technology. The anti-fouling performance of the coated tubes was investigated using the field operation parameters of air-cooled condensers, and the influence of the surface energies of the coatings on the dust adhesion was also investigated. The results demonstrated that the Ni–P coated finned tubes performed best, which reduced fouling resistance by 83.3% compared with the untreated finned tubes. The Ni–P coatings have potential applications in thermal power plants for reducing heat exchanger fouling and hence significantly decreasing waste heat and CO2 emissions. Graphic abstract
