“…Meanwhile, inorganic nanocomposites offer better mechanical properties and higher robustness (Salama & Abdel Aziz et al., 2020). Montmorillonite (Vaezi et al., 2019), SiO 2 (Karthik et al., 2021), TiO 2 (Duncan, 2011), ZnO (La et al., 2021), and Ag nanoparticles (Saedi et al., 2020) are typical elements used in inorganic nanocomposites. However, it is important to note that these inorganic compounds can only be implemented as a coating layer in whole fruits or vegetables, where additional treatment (e.g., washing or peel removal) on the coated food products is required before they can be safely consumed.…”

Along with the growth of the world's population that reduces the accessibility of arable land and water, demand for food, as the fundamental element of human beings, has been continuously increasing each day. This situation not only becomes a challenge for the modern food chain systems but also affects food availability throughout the world. Edible coating is expected to play a significant role in food preservation and packaging, where this technique can reduce the number of food loss and subsequently ensure more sustainable food and agriculture production through various mechanisms. This review provides comprehensive information related to the currently available advanced technologies of coating applications, which include advanced methods (i.e., nanoscale and multilayer coating methods) and advanced properties (i.e., active, self‐healing, and super hydrophobic coating properties). Furthermore, the benefits and drawbacks of those technologies during their applications on foods are also discussed. For further research, opportunities are foreseen to develop robust edible coating methods by combining multiple advanced technologies for large‐scale and more sustainable industrial production.

The crystal nature of the synthesized GO & rGO-AgNP sample were identi ed by measuring the diffraction intensity of the nanocomposite at 2 theta angles ranging from 10˚ -80˚ using Pert MPD X-ray diffractometer with Cu-Kα radiation working at 40 kV and 30 Ma (Karthik et al 2021;Karthik et al 2019).…”

Chlorpyrifos is a broad-spectrum organophosphate pesticide widely used for agricultural and nonagricultural applications that can highly intervene and impact with the ecosystem and affects both biotic and abiotic components. Photocatalytic degradation process using nanoparticles and nanocomposites are more fascinating as they are rapid and e cient than the existing other degradation routes. In this study, Curcubita maxima leaves are used as a novel source for green synthesis of reduced graphene oxide -silver composite in a single pot. Characterization of the novel phyto source driven composite was performed by UV-visible spectroscopy, Fourier transform infrared analysis, X-ray diffraction analysis and eld emission scanning electron microscopic methods. The assessment of degradation effect of chlorpyrifos by the synthesized nanocomposite was performed. The photocatalytic activity of the composite was demonstrated through two different process as adsorption under room temperature and photocatalysis in the presence of sunlight. Different parameters such as pH, time, photocatalyst dose and pesticide concentration were optimized. The adsorption isotherms governing the photocatalytic adsorption process were investigated to predict the adsorption capacity of the synthesized nanocomposite. In addition, the results of antimicrobial activity of the nanocomposite against grampositive, gram-negative bacteria and antifungal activity were also been found to be highly promising to utilize this composite for the removal of microbial contaminations in wastewater treatment.

“…Silica nanoparticles are one of the most known stable, biocompatible, inert, and non-toxic materials [ 1 , 2 ]. Furthermore, its silanol-rich surface makes it a perfect support for a wide range of applications via anchoring different functional groups [ 2 , 3 , 4 ]. The synthesis of uniform silica nanoparticles with a particle size in the range 100–1000 nm started by hydrolysis condensation of TEOS from aqueous solution catalyzed with ammonium in the early of 1960 [ 5 ].…”

One-Pot Synthesis of Amine-Functionalized Nano-Silica via Sol-Gel Assisted by Reverse Micelle Microemulsion for Environmental Application

Amine modified nano-silica was prepared via a one-pot route and under very mild conditions in water in oil microemulsion with a non-ionic surfactant to study the effect of changing the amount of N-[3-(Trimethoxysilyl)propyl]ethylenediamine (DA) added to the synthesis mixture on the characteristics of the obtained nanocomposite such as morphology, crystallinity, surface charge, particle size, surface area, and accordingly the effect of all of these factors on the efficiency of the nanocomposite for the removal of heavy metal ions, namely zinc, from aqueous solutions. XRD, SEM, TGA, BET, DLS, FTIR, and pH0 analysis were performed for samples and the results showed a strong effect for the amount of DA added to the synthesis mixture on the characteristics of the obtained nanocomposites. It was found that increasing the amount of DA added to the synthesis mixture increased the pH0, hydrodynamic particle size obtained by dynamic light scattering analysis, and the particle size obtained by SEM. Sample prepared without the addition of DA (SNP) and the samples prepared with 1.5 mL of DA (SNP-1.5DA) showed a better adsorption performance compared to the samples prepared with 0.5 and 1.0 mL of DA (SNP-0.5DA and SNP-1.0DA, respectively). The main factor affecting the adsorption efficiency was found to be the available surface area for each nanocomposite, which was directly related to the degree of crystallinity as obtained by XRD analysis.
