“…Their study suggested that a 40% LS cement paste is a viable option for producing green concrete with optimal fresh state and rheological properties. Tian et al [ 101 ] investigated the impacts of low surface free energy mineral admixtures, such as CaF 2 -dominated fluorite and LS, on the rheological behavior of alkali-activated slag (AAS) pastes. As the LS content increased from 0 to 30 wt%, both the yield stress and plastic viscosity decreased by 60.1% and 24.4%, respectively.…”

“…Additionally, the pozzolanic reaction of LS plays a role in consuming CH within the interfacial transition zone, thus further contributing to improved flexural strengths, particularly in the case of steam-cured LS samples [ 103 ]. However, Tian et al [ 101 ] observed a different trend in modified AAS mortars following LS incorporation. They reported a decrease in the flexural strength with increasing LS content.…”

This study critically reviews lithium slag (LS) as a supplementary cementitious material (SCM), thereby examining its physiochemical characteristics, mechanical properties, and durability within cementitious and geopolymer composites. The review reveals that LS’s particle size distribution is comparable to fly ash (FA) and ground granulated blast furnace slag (GGBS), which suggests it can enhance densification and nucleation in concrete. The mechanical treatment of LS promotes early hydration by increasing the solubility of aluminum, lithium, and silicon. LS’s compositional similarity to FA endows it with low-calcium, high-reactivity properties that are suitable for cementitious and geopolymeric applications. Increasing the LS content reduces setting times and flowability while initially enhancing mechanical properties, albeit with diminishing returns beyond a 30% threshold. LS significantly improves chloride ion resistance and impacts drying shrinkage variably. This study categorizes LS’s role in concrete as a filler, pozzolan, and nucleation agent, thereby contributing to the material’s overall reduced porosity and increased durability. Economically, LS’s cost is substantially lower than FA’s; meanwhile, its environmental footprint is comparable to GGBS, thereby making it a sustainable and cost-effective alternative. Notwithstanding, there is a necessity for further research on LS’s fine-tuning through grinding, its tensile properties, its performance under environmental duress, and its pozzolanic reactivity to maximize its utility in concrete technologies. This study comprehensively discusses the current strengths and weaknesses of LS in the field of building materials, thereby offering fresh perspectives and methodologies to enhance its performance, improve its application efficiency, and broaden its scope. These efforts are driving the sustainable and green development of LS in waste utilization and advanced concrete technology.

“…At present, organic silicon materials are widely used as antifouling surfaces because of their low-surface-energy characteristics, which can efficiently interrupt the attachment of microorganisms. Moreover, nontoxic organic silicon coatings are environmentally friendly, which can prevent pollution caused by nontarget organisms poisoning in the ocean. − As a result, scientists employed silicone materials for the fabrication of biomimetic antifouling textured surfaces. Referred to the biomimetic design, these textured surfaces could better show excellent antifouling and drag reduction effects. , This means to achieve the purpose of antifouling by changing the solid surface textures reduces the use of chemical reagents to some extent.…”

The nature always offers amazing inspiration, where it is highly desirable to endow coatings on marine equipment with powerful functions. An excellent example is slippery zone of Nepenthes pitcher, which possesses novel liquid-repellent and selfcleaning performance. Therefore, this study presents an efficient fabrication method to prepare a novel coating. The coatings were fabricated by designing biomimetic textures extracted from the lunate bodies of slippery zone on polydimethylsiloxane (PDMS) and then grafting Dictyophora indusiata polysaccharide (DIP) modifier. The as-prepared slippery coatings exhibited outstanding antifouling properties against kinds of daily life pollutants such as Chlorella and coffee. This synergistic strategy was proposed combined with environmentally friendly modifier grafting and heterogeneous microstructure on the surface to broaden new probabilities for manufacturing slippery coatings with incredible protective functionality.
