Microorganisms have existed for hundreds of millions of years and they have adapted to colonize on surfaces. [1] Bacteria are ubiquitous in the human living environment. Most bacteria spread through medical equipments and contacting with each other. [2] All over the world, the diseases caused by bacterial infections have brought terrible catastrophe to human beings. [3][4][5][6][7] Generally, people infected with infectious diseases are directly or indirectly related to contact with pathogenic microorganisms. The main stages of the attachment of bacteria at the interface include the migration of bacteria to the surface, the reversible and irreversible interactions between bacteria and the interface, the specific adsorption of bacteria on the substrate, and the proliferation of bacteria, thus forming a bacterial biofilm on the surface (Figure 1). [8] The bacteria can multiply quickly under suitable conditions, which induce various diseases and cause invalidation of apparatus. The colonization of bacteria on surfaces can result in chronic infections, [9] the failure of medical implants, [10] the biological corrosion of industrial equipments, [11] reducing various surface properties, such as petroleum and other pipelines systems, clothes, and other harmful phenomena. [12] Currently, antibiotics are mainly used to inhibit or kill bacteria to maintain surface hygiene and prevent infections. However, as bacteria develop resistance to antibiotics, it is suggested that antibiotics should be much more cautiously used. It is estimated that antimicrobial resistance infections will kill as many as 10 million people every year by 2050. [13] Antimicrobial resistance is now an urgent international issue that requires imperative solutions, more effective antibacterial techniques are needed to fight bacterial infections. Inspired by the superwetting properties of plants and marine life, Li et al. [14] reviewed the research progresses of the preparation of superwetting materials including of superhydrophobic/superoleophilic and superhydrophilic/underwater superoleophobic materials and their applications for removal of organic pollutants, which provided a basis for the design of a new type of superwetting materials that efficiently remove organic pollutants in the water. Similarly, Tian et al. [15] developed a superwetting thin-film nanofibrous composite membrane with antifouling, self-cleaning, and oil-in-water emulsions separation properties. The as-prepared carbon nanotubes (CNTs) layer with superhydrophilic and underwater superoleophobic properties could absorb water as a selective layer to remove oil droplets from oil-in-water emulsions to present antifouling. The self-cleaning properties were promised by the continuously up-flowed permeate water. They claimed that the work provided a new insight for developing oil/water separation membranes which suffer from fouling and clogging. Also, Li et al. [16] summarized the recent progresses in smart polymeric materials for fabricating switchable superwettability surfaces and their oi...

“…To date, many techniques and methods have been utilized for the removal of toxic dyes, including adsorption, photocatalysis, and biodegradation [ 10 ]. Remarkably, the adsorption method has been extensively applied for the treatment of dye wastewater because of its low cost, simple operation, and practicality [ 11 , 12 , 13 ]. It is essential to remove contaminants from water before releasing it into the environment.…”

In view of the water pollution issues caused by pathogenic microorganisms and harmful organic contaminants, nontoxic, environmentally friendly, and efficient antimicrobial agents are urgently required. Herein, a nickel-based Keggin polyoxomolybdate [Ni(L)(HL)]2H[PMo12O40] 4H2O (1, HL = 2-acetylpyrazine thiosemicarbazone) was prepared via a facile hydrothermal method and successfully characterized. Compound 1 exhibited high stability in a wide range of pH values from 4 to 10. 1 demonstrated significant antibacterial activity, with minimum inhibitory concentration (MIC) values in the range of 0.0019–0.2400 µg/mL against four types of bacteria, including Staphylococcus aureus (S. aureus), Bacillus subtilis (B. subtilis), Escherichia coli (E. coli), and Agrobacterium tumefaciens (A. tumefaciens). Further time-kill studies indicated that 1 killed almost all (99.9%) of E. coli and S. aureus. Meanwhile, the possible antibacterial mechanism was explored, and the results indicate that the antibacterial properties of 1 originate from the synergistic effect between [Ni(L)(HL)]+ and [PMo12O40]3−. In addition, 1 presented effective adsorption of basic fuchsin (BF) dyes. The kinetic data fitted a pseudo-second-order kinetic model well, and the maximum adsorption efficiency for the BF dyes (29.81 mg/g) was determined by the data fit of the Freundlich isotherm model. The results show that BF adsorption was dominated by both chemical adsorption and multilayer adsorption. This work provides evidence that 1 has potential to effectively remove dyes and pathogenic bacteria from wastewater.

“…Due to the special composition and structure, PSQ has many unique and excellent properties (Tang et al, 2013;Rathnayake et al, 2021), for instance, the organic groups connected with Si can be connected with other groups through different chemical reactions (Wang et al, 2014). In addition, PSQ has distinct corrosion resistance, thermal stability, chemical reactivity Liu et al, 2021), and can be used in semiconductor materials, catalysis, adsorption, and other fields (Wu et al, 2018;Park et al, 2020;Kong et al, 2021). PSQ as an adsorbent commonly has high adsorption capacity and adsorption rate (Sun et al, 2014;Wang et al, 2020b).…”

Amino-thiol bifunctional polysilsesquioxane/carbon nanotubes (PSQ/CNTs) magnetic composites were prepared by sol-gel method with two types of functional siloxanes coating on carboxyl CNTs simultaneously. The composites were served as efficient adsorbents for removing Hg(II) in aqueous solution and the adsorption properties were investigated systematically. The optimal pH of bifunctional composites for Hg(II) removal is at pH 4.5. The thermodynamic fitting curves are more consistent with the Langmuir model and the adsorption capacities of the bifunctional composites for Hg(II) varied from 1.63 to 1.94 mmol g−1 at 25°C according to the Langmuir model. The kinetics curves are more fitted to the pseudo-second-order model and the composites could selectively adsorb Hg(II) in a series of binary metal ions solution. The elution regeneration tests showed that the adsorption rate could still reach 78% after repeat cycle three times. It is expected that the bifunctional PSQ/CNTs magnetic composites can be potentially applied to remove low concentration Hg(II) from waste water.
