“…An approach to treating aerosols is spray pyrolysis hat converts liquids to solid particles through a process known as “breakdown.” Sols are utilized to produce nanostructured materials, hence the name “liquid‐phase method” for this technique. Spray pyrolysis creates the beginning solution by dissolving solutes or reactants in the solvent, also known as a precursor 62 . A precursor containing solution is sprayed or injected onto a heated substrate in a furnace during the spray pyrolysis procedure, which results in the decomposition of the precursor and the formation of the final desirable substance on the substrate.…”

The creation of effective and clean energy storage technologies has advanced dramatically due to growing worldwide worries over the depletion of fossil fuels and environmental issues. Energy storage and conversion systems have emerged as a crucial component with the development of numerous electronic devices, enabling the devices to function for extended periods of time. Due to their enormous surface area, strong electrical conductivity, and ion transport, 3D self‐supported nanoarchitectures associated with electrochemical energy storage (EES) devices can offer alternatives for enhancing the performance and advancement of existing EES systems. Here, we present the results of our findings regarding the design, production, and use of self‐supported 3D nanostructures in energy storage and conversion systems such as supercapacitors, batteries, solar cells, and fuel cells. A variety of advanced 3D nanomaterials may be readily created on an immense scale using various synthetic techniques, and they have a great deal of potential for use as electrodes in energy storage and conversion devices with much better performance. These fabrication techniques include electrochemical deposition, electrospinning, chemical precipitation, spray pyrolysis, sol‐gel method, hydrothermal method, chemical vapor deposition, and so forth.

“…On the other hand, laser ablation uses an intense pulsed laser beam to remove regions of matter by vaporizing atoms of the target (Shojaei et al, 2022). This technique allows the development of nanoparticles and nano-systems without the use of chemical compounds and provides advantages such as a low number of impurities and the agglomeration of nanoparticles during synthesis (Kugarajah et al, 2022).…”

Traditional agriculture from cropping to harvesting is contributing to climate change by increasing global greenhouse emissions. Circular economy approaches and biorefinery technologies based on the reuse, recycling, and remanufacturing might result in the valorization of wastes that consequently would avoid environmental pollution. Nanoparticles synthesis using bio-waste such as stems, leaves, seeds, pulp, stubble, and bagasse is considered a green approach with low energy consumption, and low-cost production. Characteristics of raw materials influence the final application of nanoparticles in edible coatings, and films. Therefore, the preparation of nanoparticles based on cellulose, pectin, metal (titanium oxide, silver, zinc oxide), or silica are considered organic, inorganic, or hybrid nanocomposites, are resulted in several benefits including shelf-life extension and broad-spectrum antimicrobial properties by its capacity to encapsulate active compounds that greatly improve food preservation. For considering agro-waste-based nanoparticles in food, challenges in homogenization and synthesis, yield, and toxicity are mainly described. Therefore, this review examines the employment of agro-industrial waste for the development of sustainable nanoparticles and their synthesis methods (top-down and bottom-up). Moreover, it discusses their incorporation and role in active edible coatings and films by highlighting their bioactive properties, mechanisms of action, and applications in food group preservation.
