Title: Enhancing Environmental Sustainability and Energy Efficiency in Nanomaterial Processes Through Cavitation
Abstract:
Significant attention is currently focused on the exploration of nanomaterials, driven by their diverse applications. The distinct properties of nanoparticles, compared to their bulk counterparts, have sparked extensive research efforts. Various fabrication methods, such as co-precipitation, microemulsion, supercritical sol-gel processing, hydrothermal synthesis, and high-energy ball milling, have been employed for nano-entity production. However, the limitations of these conventional methods have led to a surge in interest in innovative synthetic approaches. The utilization of cavitation for synthesizing compounds under milder conditions has gained popularity in materials engineering. This method offers a notable advantage by enabling precise control over both the synthetic process and the nanostructure of advanced materials. The process, characterized by atomic-level mixing within the precursor system, ensures chemical homogeneity and reactivity, allowing the preparation of phase-pure crystals at reduced temperatures through annealing. This technique has facilitated the generation of diverse nanomaterials and nanodispersions, finding applications across various technological domains. Furthermore, the incorporation of novel carbon materials, such as graphene and fullerene, into sensors has led to the functionalization and development of nanocomposites.
