“…For example, to produce 0.5 g of (Fe 0 /TNW) with 50% mass ratio of TNW, 0.25 g of TNWs and 1.25 g of ferric chloride hexahydrate were mixed in 20 mL of ethanol for 10 min and ultrasonicated for 30 min before adding 50 mL of deoxygenated deionized water (DDIW) to prepare the 92.49 mM of ferric chloride solution. Then, the ferric ions (Fe 3þ ) were reduced to Fe 0 by the introduction of 581.55 mM of sodium borohydride under anaerobic environment (Bensaida et al 2020a). The final black precipitates were cleaned three times using 150 mL of DDIW during the vacuum filtration process.…”

The development of antimicrobial resistance genes (AMRs) in water was globally accelerated due to the occurrence of ciprofloxacin (CIP) in water. This study aims to precipitate iron nanoparticles (Fe0) on the surface of titanium nanowires (TNWs) through a chemical process to overcome the limitations of Fe0 and efficiently remove CIP from water. TEM and XRD results confirmed the successful synthesis of Fe0 and TNWs. They also proved the successful deposition and dispersion of Fe0 on TNWs. Several (Fe0/TNW) nanocomposites were synthesised with different percentages of TNWs (5, 10, 20, 30, and 50%) to define the best TNWs ratio that will decrease the aggregation of Fe0 nanoparticles and achieve an outstanding removal efficiency of CIP. (Fe0/TNW) nanocomposite with 20% of TNW was nominated as the best nanocomposite because it demonstrated a promising performance, compared with other nanocomposites, by removing more than 67% of CIP with insignificant desorption behaviour during the treatment period (120 min). Dosage of (20%-Fe0/TNW), initial pH of CIP solution and reaction temperature were optimized through a group of batch experiments to efficiently remove CIP from water. The optimum removal of CIP was obtained by 1 g L−1 of (20%-Fe0/TNW) nanocomposite at initial pH of 7 under 35 °C.

“…FeO ion, which is known as Nanoscale zerovalent iron particles (nZVI), is massively used in the synthesis of nanoparticles applied in wastewater nano-based treatments. Bensaida et al have shown that combining nZVI with another metal (Cu) enhances the growth of the microbial populations in the wastewater treated with this nZVI\Cu bimetallic nanoparticles (Bensaida et al 2021).…”

Nanotechnology is one of the most emerging fields of research within recent decades and is based upon the exploitation of nano-sized materials (e.g., nanoparticles, nanotubes, nanomembranes, nanowires, nanofibers and so on) in various operational fields. Nanomaterials have multiple advantages, including high stability, target selectivity, and plasticity. Diverse biotic (e.g., Capsid of viruses and algae) and abiotic (e.g., Carbon, silver, gold and etc.) materials can be utilized in the synthesis process of nanomaterials. "Nanobiotechnology" is the combination of nanotechnology and biotechnology disciplines. Nano-based approaches are developed to improve the traditional biotechnological methods and overcome their limitations, such as the side effects caused by conventional therapies. Several studies have reported that nanobiotechnology has remarkably enhanced the efficiency of various techniques, including drug delivery, water and soil remediation, and enzymatic processes. In this review, techniques that benefit the most from nano-biotechnological approaches, are categorized into four major fields: medical, industrial, agricultural, and environmental.

“…The cathode compartments have plenty of oxygen as it is exposed to air. Thus, electrons are released to electron acceptor, i.e., oxygen [2,3]. Dual chamber MFC can reduce the overall cost as no proton exchange membrane (PEM) is required here.…”

Microbial fuel cell (MFC) is a new source of renewable energy where wastewater is used as fuel. Various microorganisms and organic and inorganic compounds are present in wastewater. Microorganisms with various reactions produce electricity using these organic compounds. Advanced study on MFCs can bring it to practical use and reduce the over dependence on fossil fuel. But expensive proton exchange membranes (PEM), electrode material and low power generation is a big barrier towards its development. Besides the share of solid food waste in municipal waste is increasing day by day. Food waste has high number of bio-degradable compounds which can be used as the fuel of MFC. In current study, three MFCs are made with food waste solution and three different combinations of easily available electrode materials such as Copper, Zinc and Graphite. The measured voltage had its peak values between 8 to 10 hours since the experiment started. With the help of various equations, a one-dimensional single particle half-cell model was generated which was used to simulate voltage graph with respect to time. The experimental value was compared with the simulation result for each cell. The validation of experimental result was used to predict the best possible combination of electrodes in microbial fuel cell with food waste solution. Detail of this research will provide useful information on the usage of various electrode materials and food waste to be used in MFC.
