“…From the bar of the micrographs the sizes of our CMLF particles are in the nanometric range (<100 nm) [34], see figures 3(a)-(c). Also, these figures reveal the accumulation of the CMLF particles, where the CMLF nanoparticles' magnetic nature collect the particles together leading to this agglomeration.…”

Improving effective and thrifty photocatalysts was deemed an outstanding approach for pollution handling. Here, a novel magnetic Co0.5Mg0.5LaxFe2-xO4 nanoparticle photocatalysts were synthesized via a combustion approach for the harmful methylene blue (MB) dye degradation. These samples were labeled as Co0.5Mg0.5Fe2O4 (CMLF0), Co0.5Mg0.5La0.03Fe1.97O4 (CMLF1), Co0.5Mg0.5La0.06Fe1.94O4 (CMLF2), Co0.5Mg0.5La0.09Fe1.91O4 (CMLF3), Co0.5Mg0.5La0.12Fe1.88O4 (CMLF4), and Co0.5Mg0.5La0.15Fe1.85O4 (CMLF5). A sequence of characterizations, including XRD, STEM, and UV–Vis-DRS, was exploited to examine the structure, morphology, constituent elements, and optical features of the CMLF ferrite nanoparticles. Despite the substitution process, an amazing decrement result for the lattice parameter (8.3748 to 8.3610 Å) and crystallite size (21.87 to 13.95 nm) is a large La cation at the expense of a smaller Fe one. The band-gap behavior of the CMLF nanoferrites is unique; it increases from 1.528 eV at the CMLF0 to 1.547 eV at the CMLF3 and decreases to 1.526 eV at the CMLF4 and 1.520 eV at the CMLF5. Two justifications accounted for this behavior. The nanoferrite CMLF5 has the highest photodegradation efficiency, 96.09 %, after 60 minutes. Three hypotheses were introduced to explain this result. After five cycles, the degradation efficiency of the nanoferrite CMLF5 maintained its high performance with 95.09 %, 94.87 %, 94.76 %, 93.59 %, and 93.44 %, respectively. These outcomes validate the outstanding photocatalytic efficiency, recyclability, and stability of the CMLF5 photocatalyst in its task to degrade the harmful MB dye, making it acceptable for wastewater treatment applications.

“…In recent years, polymers have begun to replace other raw materials in the field of packaging, but alone, they are often unable to meet consumer requirements and, as a result, some alternatives have emerged to enhance their properties and even increase others to obtain a final product in the desired form, such as mixing with nanomaterials. Nanomaterials, since their production began, introduced significant changes in properties, as they are materials that have at least one of their dimensions in the nano‐size scale (1 nm = 10 −9 m) and, as a result, exhibit new or superior properties concerning materials on a macro or micro scale 5 …”

Furthermore, when nanofillers are previously combined (nanohybrids) to act together and dispersed within a polymeric matrix, there are synergistic results.…”

Packaging has important functions for products, contributing to their protection and presenting information. Recognizing that food loss and waste affect all countries, it is necessary to search for alternatives that change this scenario, such as active packaging. Particles with sizes between 1 and 100 nanometers (nanoparticles) are incorporated into polymeric materials because they are capable of improving or even providing properties that the film formed by the pure polymer does not have, due to its surface area being greater than that of macro‐sized particles. If two nanoparticles are previously combined to form a nanohybrid before being dispersed in a polymeric matrix, in addition to having this purpose, they can provide even better results when incorporated, due to the synergistic effects that can be attributed to the nanoparticles used. The utilization of active packaging composed of nano‐hybrids within biodegradable polymers holds significant potential for reducing solid plastic waste and the generation of persistent microplastics, thereby positively impacting human health. In this literature review, the effects of nanohybrid on antibacterial and barrier properties for application in food packaging in polymeric matrices were investigated using materials such as: nickel nanoparticles, zinc oxide nanoparticles, silver nanoparticles, copper oxide nanoparticles, cellulose nanowhiskers, Cloisite 30B, sodium alginate, poly(ethylene oxide), starch, poly(vinyl alcohol), chitosan and gelatin. The results were found to show the efficiency of nanohybrids in polymeric matrices, decreasing the water vapor and oxygen permeability and also increasing the antibacterial activity, which can prevent illnesses stemming from contaminated food occurs.

“…Their small size results in an increase in surface area to volume ratio, making NMs more chemically reactive than their bulk-scale counterparts [ 2 ]. Additionally, at the lower end of the nanoscale spectrum, NMs display quantum effects, whereby properties such as fluorescence, conductivity, magnetic permeability, and chemical reactivity deviate from standard bulk material behaviour and become a function of particle size [ 3 ]. These novel properties make ENMs desirable for several new applications, thus making them more frequently incorporated into consumer products such as cosmetics, paints, textiles, and electronics [ 4 ], as well as being utilised in industrial-scale processes and novel biomedical practices.…”

A Review of the Aquatic Environmental Transformations of Engineered Nanomaterials

Once released into the environment, engineered nanomaterials (ENMs) undergo complex interactions and transformations that determine their fate, exposure concentration, form, and likely impact on biota. Transformations are physical, chemical, or biological changes that occur to the ENM or the ENM coating. Over time, these transformations have an impact on their behaviour and properties. The interactions and transformations of ENMs in the environment depend on their pristine physical and chemical characteristics and the environmental or biological compartment into which they are released. The uniqueness of each ENM property or lifecycle results in a great deal of complexity. Even small changes may have a significant impact on their potential transformations. This review outlines the key influences and outcomes of ENM evolution pathways in aquatic environments and provides an assessment of potential environmental transformations, focusing on key chemical, physical, and biological processes. By obtaining a comprehensive understanding of the potential environmental transformations that nanomaterials can undergo, more realistic models of their probable environmental behaviour and potential impact can be developed. This will, in turn, be crucial in supporting regulatory bodies in their efforts to develop environmental policy in the field of nanotechnology.
