Summary: Biofouling is the problematic attachment and colonization of fouling organisms on submerged materials, causing economic losses and maintenance costs. Traditional antifouling methods rely on biocides but harm the environment. Biomimicry offers a more environmentally friendly approach to antifouling.

Summary: Aquaculture is a global industry that plays a vital role in providing sustainable protein-rich foods to feed the growing world population. A study shows that using highly wettable (hydrophilic) surface coatings can effectively reduce biofouling in aquaculture, while water-repellent (hydrophobic) coatings have a less desirable outcome. Modified poly(4-vinylpyridine) coatings exhibited low toxicity and demonstrated antifouling properties against commonly grown marine microalgal species used as aquaculture food.

Summary: In this study, anti-biofouling metallic surfaces with hierarchically ordered structures were produced using top-down fabrication. These surfaces featured few attachment points for organisms and prevented the attachment of bacteria and algal zoospores, while also inhibiting the settlement of macrofoulers. Superhydrophilicity induced by anodic oxidation further enhanced the anti-biofouling properties. Laboratory settlement assays confirmed that bacterial attachment was dramatically reduced by the nanostructures and/or the hydration layer. Over 77 days of static immersion, the metallic surface showed significantly less biofouling compared to a surface with an anticorrosive coating.

Summary: Bacteria growing inside biofilms are more resistant to hostile environments, conventional antibiotics, and mechanical stresses. Marine microorganisms are a prolific source of natural products, but only a few anti-biofilm natural products derived from them have been reported. Some antifouling compounds can be considered as potential anti-biofilm agents. This review summarizes 112 anti-biofilm, anti-larval, and anti-algal natural products from marine microbes, along with 26 synthetic analogues, from 2000 to 2021.

Summary: Biofouling on ship hulls can lead to increased fuel consumption and the spread of nonindigenous species. To objectively evaluate the performance of fouling control coatings (FCC), a standardized biofouling recognition model using image analysis was developed. This model provides a simple segmentation of different biofouling categories, allowing for the determination of biofouling coverage percentage. The results from the model were compared with manual evaluations to assess the accuracy of the model.

Summary: Marine biofouling is a significant issue for marine structures, causing a loss in operational capabilities and economic revenues. The formation of biofilms is the key process in this fouling, and anti-barnacle coatings are a potential solution for mitigation. However, further development is needed to make these coatings commercially available.

Summary: Biofouling is a challenge for the shipping industry, but the use of UVC light shows promise in preventing it. This study found that UVC exposure had different effects on biofouling depending on surface material and color. Regular short intervals of UVC exposure were effective in reducing biofouling settlement.

Summary: This research tests the efficacy of phosphonium ion gels in preventing biofouling and examines the impact of hydrophobicity and biocide concentration on anti-fouling performance. The study finds that formulations with higher hydrophobicity exhibit better anti-fouling performance, while the presence of copper(II) biocide negatively affects it. Furthermore, no correlation is observed between antimicrobial activity and anti-fouling performance.

Summary: This paper proposes a numerical back analysis method for estimating the three-dimensional in situ stress fields of large deep underground caverns in complex geological environments. By utilizing stepwise regression, the collinearity between independent variables is associated with surface topography while eliminating insignificant variables caused by collinearity. The method was validated in an underground powerhouse of a hydropower station and showed reliable estimation of the 3D in situ stress field. It also established multidimensional mathematical models with improved predictive ability and clear physical meaning, quantifying the contributions of geological actions and stress sources.

Summary: In this study, we characterized and analyzed eight types of chitosan fibers in terms of their composition, surface morphology, and mechanical properties. We also investigated the antibacterial activity of these fibers against Escherichia coli, Staphylococcus aureus, and Candida albicans, and examined the relationship between antibacterial activity and the molecular weight and degree of deacetylation. Additionally, we determined the antibacterial mechanism of chitosan fibers. The findings provide insights into the properties of chitosan fibers and offer effective strategies for enhancing their antibacterial activity and applications in antibacterial textiles.
