Recent research reveals exciting developments surrounding the bio-inspired preparation of silver nanoparticles (Ag NPs), reduced graphene oxide (rGO), and Ag/rGO nanocomposites, indicating their multifaceted potential across acoustical, antioxidant, and agricultural applications. Conducted by researchers affiliated with Shivaji University, this investigation utilized Bos taurus indicus metabolic waste as a green synthesis method, providing innovative insights for the development of safe and effective nanomaterials.
The study's primary focus was on the acoustical properties of these nanomaterials. Acoustical parameters are pivotal for comprehending the molecular interactions within fluids, which, when optimized, can significantly improve their effectiveness for various applications, from biomedical settings to environmental sustainability. The findings emerged from thorough characterization using advanced techniques such as X-ray diffraction (XRD) and transmission electron microscopy (TEM), providing extensive data on the properties and behaviors of the synthesized composites.
Among the significant conclusions drawn from the research were the acoustical analyses, which revealed intriguing results at varying concentrations. It was found there exists a direct correlation between nanofluid concentration and key acoustical parameters, such as density and ultrasonic velocity. At lower concentrations, enhancements were noted in properties like adiabatic compressibility and apparent molar volume, indicating improved nanoparticle-solvent interactions. Irregularities observed at higher concentrations signal unique structural responses, which could be beneficial for developing new acoustic technologies.
Beyond their acoustical attributes, Ag/rGO nanocomposites displayed pronounced antioxidant potential. The antioxidative assessments demonstrated DPPH scavenging activity as high as 65.69%, indicating their effectiveness against oxidative stress—a condition linked to many chronic diseases. This trait not only underlines the relevance of these materials for therapeutic applications but also aligns with growing interest in utilizing green technologies for healthcare advancements.
The agricultural tests revealed compelling results as well, showcasing the efficacy of Ag/rGO nanocomposites as plant growth regulators. Enhanced germination rates were documented, with 100% for spinach and 40% for fenugreek at specific low concentrations. These positive outcomes imply simple applications of such nanocomposites could substantially advance agricultural practices, promoting crop yield and robustness.
The absence of hazardous substances, such as cetyltrimethylammonium bromide (CTAB), during synthesis reinforces the safety of the Ag/rGO nanocomposites, ensuring they pose fewer risks to plants and humans compared to traditionally synthesized nanoparticles. With superior antioxidant performances and effective growth regulation, these materials reveal the potential for transformative impacts across biomedical, agricultural, and environmental sectors.
This research builds upon prior studies emphasizing the multifaceted capabilities of nanomaterials, highlighting the importance of green chemistry and biogenic synthesis methods. Further exploration could focus on their long-term stability, environmental impact, and broader applications, paving the way for advancements within sustainable and innovative nanotechnology.
