“…252 To enable this kind of research "realtime monitoring models" must be developed to assess the stability and performance thereof of the biocidal nanomaterials during the water treatment process. 247 At the moment, some simplified models like DFT calculations can be used to provide accuracy in evaluating experimental data and predict potential directions. Needless to say, improved longevity of these unique nanomaterials can hasten the commercialization of antibiofouling-based membranes.…”

“…246 Further, despite the undeniable progress in the use of NPs in polymer membranes for inactivation of microbes, there have been no "real-time monitoring models" to assess NPs leaching and hence the effectiveness of the biocidal nanocomposite membranes over time. 247 The toxicity of the membrane nanocomposites toward living organisms and the environment is not yet fully understood probably because there are only a few studies done on the toxicity of various nanomaterials. Of the few available reports, the toxicity studies are carried out in vitro, so the full impact of NPs in vivo is not yet comprehended.…”

Membrane biofouling is a major stumbling block in membrane technology and particularly in the water treatment industry. Biofouling, in particular, is a serious concern because it is irreversible and thus cuts the lifespan of the polymeric membranes. This review, therefore, explores the fundamentals of biofouling development and the factors that promote biofilm growth in polymeric membrane systems. In this pursuit, we discuss avenues through which antibiofouling polymeric membranes have been fabricated using inorganic and carbon-based nanomaterials as membrane nanofillers to enhance the hydrophilicity and antibiofilm properties of the resultant composite membranes without significantly compromising the membrane filtering abilities. We further elucidate the chemistry by which the membrane nanofillers mitigate or inhibit the formation and growth of the undesirable biofilms on the surface and pores of the membranes. In achieving this, recent works on polymeric membrane biofouling are reviewed, with a particular focus on the correlation between the membrane performance and the physicochemical properties of the filler nanomaterials. The merits and demerits of inorganic and carbon-based nanomaterials as fillers to confer an antibacterial effect to the membranes are presented and perspectives and opinions on the future direction of biofouling mitigation in membranes are outlined.

Contamination of soil and water by heavy metals and metalloids is one of the major issues that are being raised and addressed globally as it has adverse effects on the environment as well as on human health. Since each technique has its own pros and cons, integration of a few methods helps in getting effective and efficient results. Application of nanotechnology has led to the overcoming of various drawbacks of conventional methods of remediation. Nanobioremediation is an extended branch of nanotechnology that deals with the removal of pollutants from the site of contamination by utilizing biogenic nanoparticles or materials synthesized from biological sources that are of nano size. This technique has an edge over other methods because of size of the material; smaller the size, higher would be the surface area to volume ratio and higher the ratio, more surface would be available for the reaction to occur. In recent years, the green synthesis of nanoparticles has gained enormous attention because of the economic and ecological aspects. This review highlights the implications and health risks of heavy metals and metalloids along with the application of nanotechnology in the bioremediation of these contaminants.

“…Stable dispersion in a low dielectric constant suspension requires a strong repulsive force to overcome the interparticle attraction. The most commonly used methods are electrostatic, steric, and electrosteric stabilization . A small concentration of metal salts in the solvent (Al 3+ , Mg 2+ , Ni 2+ ) is necessary to form a hydroxide layer to support the adhesion of CNTs to the substrate. − Metal salts not only influence adhesion but also affect the dispersion of CNTs.…”

Electrophoretic deposition (EPD) is the potential process in high porosity thin films’ fabrication or complex surface coating for perovskite photovoltaics. Here, the electrostatic simulation is introduced to optimize the EPD cell design for the cathodic EPD process based on functionalized multiwalled carbon nanotubes (f-MWCNTs). The similarity between the thin film structure and the electric field simulation is evaluated by scanning electron microscopy (SEM) and atomic force microscopy (AFM) results. The thin-film surface at the edge has a higher roughness (Ra) compared to the center position (16.48 > 10.26 nm). The f-MWCNTs at the edge position tend to be twisted and bent due to the torque of the electric field. The Raman results show that f-MWCNTs with low defect density are more easily to be positively charged and deposited on the ITO surface. The distribution of oxygen and aluminum atoms in the thin film reveals that the aluminum atoms tend to have adsorption/electrostatic attraction to the interlayer defect positions of f-MWCNTs without individually depositing onto the cathode. Finally, this study can reduce the cost and time for the scale-up process by optimizing the input parameters for the complete cathodic electrophoretic deposition process through electric field inspection.
