“…The D h of filmeforming mixtures was mostly greater than 100 nm and greater than <30 nm of the microemulsion alone (Ma & Zhong, 2015). The D h being greater than 10e50 nm typically expected in microemulsions (Slomkowski et al, 2011) indicates the filmeforming mixtures were no longer microemulsions. This is because microemulsions are formed at a specific combination of thermodynamic conditions but the solvent in the filmeforming mixture is no longer being equal masses of PG and water (as in microemulsions before mixing chitosan solution.…”

“…Microemulsions are thermodynamically stable isotropic mixtures of water, oil, surfactants, and co-surfactants (Danielsson & Lindman, 1981). Microemulsions are transparent because their droplets are from 1 to 100 nm, typically 10e50 nm (Moulik & Paul, 1998;Slomkowski et al, 2011). The interfacial tension in microemulsions is very low, which enables their easy preparation without using high mechanical energy as in conventional emulsification (Klossek, Marcus, Touraud, & Kunz, 2014).…”

“…In this way, the size and the porosity of the spherical particles are easily controlled by choosing the appropriate reaction mixture [95], but with the possibility that the monomer and the template could be irreversibly solubilized causing a partial loss of the reagents and hence a decrease of the polymerization yield [96]. Another option is represented by the emulsion polymerization in which two immiscible solvents are used in the presence of a stabilizing surfactant to obtain small droplets (micelles) inside which the polymerization reaction takes place [97]. A similar procedure, even though more complex, is represented by the Pickering emulsion polymerization [98], where solid particles are used to stabilize the small droplets formed in the mixture of two immiscible liquids, thus eliminating or reducing the dependence on surfactant emulsifiers and making the procedures cheaper.…”

Contaminants of emerging concern (CECs) are one of the main barriers in the water cycle as they limit the water reuse due to their adverse effects on humans and the ecosystem. Natural and/or engineered ecosystems, such as conventional wastewater treatment processes, are not designed to remove CECs and contribute to the bioaccumulation in organisms considering high volumes of treated water discharges. The adoption of innovative solutions to upgrade urban water cycle facilities has gained relevance for the removal of these substances from final effluents. Molecularly imprinted polymers (MIPs) show promising selective removal toward a wide range of CECs. However, this solution is still limited to lab/bench scale and needs to be critically analyzed and assessed for possible scale-up in real environment. Therefore, in this review, an overview of the fate and occurrence of CECs in wastewater is initially reported together with the state-of-the-art in adsorption mechanisms to remove these compounds. In the central part of the paper, an evaluation of MIPs synthesis and their status in removing CECs from water matrix are presented. An upscaling pathway of MIPs column from lab-to pilot-scale is given to be applied for enhanced CECs removal and safe water reuse in irrigation/fertigation. Finally, possible integrations of MIP columns to real wastewater treatment facilities is discussed and advantages and disadvantages of the potential solutions are addressed to enhance their sustainability.

In detail characterisation of suspensions including nanomullite, nanosilicon carbide and various percentages of their composites has been studied in this Letter. Mechanism of particle ionisation, alternate pH and surface charge, particle size distribution, zeta potential, current density, electrophoresis movement and kinetics of time-weight curves has been studied, thoroughly. It was illustrated that triethanolamine cannot stabilise powders as well. However, poly-vinyl pyrrolidone could stabilise the particles as well but the particles could not move easily in the presence of applied electrical field due to the lack of enough surface charge. In this case, iodine (I) could be utilised as the preferred surfactant due to good stability and enough surface charge even though it could increase the concentration of free ions and conductivity of particles may be decreased. It was also found that in the case of utilising optimum surfactant, the amount of zeta potential for mullite suspension is more than composite powder and these two have a greater zeta potential than SiC suspension. Last but not least, it was found that the velocity of deposition reduces by increasing the time and its reduction depends on resistance and permittivity of suspension.
