“…Magnetic nanoparticles have shown great potential in the removal of traces of Sr(II), [ 266 ] perfluorooctane sulfonate, [ 267 ] chloroauric ions, [ 268 ] and other organic and inorganic pollutants from contaminated water. [ 269 ] Magnetotactic bacteria can easily move under a magnetic field because of their magnetosomes.…”

Bacteria play an important role in the calcification process of natural minerals and within organisms ( Table 1). It is Microbe-mediated mineralization is ubiquitous in nature, involving bacteria, fungi, viruses, and algae. These mineralization processes comprise calcification, silicification, and iron mineralization. The mechanisms for mineral formation include extracellular and intracellular biomineralization. The mineral precipitating capability of microbes is often harnessed for green synthesis of metal nanoparticles, which are relatively less toxic compared with those synthesized through physical or chemical methods. Microbe-mediated mineralization has important applications ranging from pollutant removal and nonreactive carriers, to other industrial and biomedical applications. Herein, the different types of microbe-mediated biomineralization that occur in nature, their mechanisms, as well as their applications are elucidated to create a backdrop for future research.

“…Adsorbents with small pore size and high SSA can lead to high PFAS sorption capacity. Similarly, adsorbents with a basic or positively charged surface tend to show high PFAS sorption capacity through the combined mechanism of hydrophobic interaction and electrostatic attraction (Lu et al, 2016).…”

“…Both SBMIM ± and TfO * contain a sulfonate group having an a nity for oxide surfaces. [29,44] A localisation of some TfO * ions would therefore disturb the monolayer of SBMIM ± zwitterions due to their size di erence and hence the multilayer structure formed behind, explaining the difference observed in the colloidal stability.…”

<div> <div> <div> <p>The use of ionic liquid-based colloids at elevated temperatures is one of their most promising fields of application. However long term stability on the whole range of temperature is mandatory. First a detailed study on colloidal dispersions of iron oxide nanoparticles in EMIM TFSI is performed at room temperature in order to determine the best solid/liquid interface. The previously identified key parameters are tuned: the surface charge density and the nature of the counterions. Here a sulfonate based imidazolium ion is chosen. In a second step, the thermal stability of these nanoparticle dispersions is analysed on the short and long term up to 473 K (200◦C) combining dynamic light scattering (DLS), small angle X-ray/neutron scattering (SAXS/SANS) and thermogravimetric analysis (TGA). Ionic liquid-based colloidal dispersions of iron oxide nanoparticles in EMIM TFSI stable in the long term can be obtained at least up to 473 K and nanoparticle concentrations of 12 vol% (≈30wt%) </p> </div> </div> </div>
