Squeezed silver-capped iron oxide nanoparticles flow and CCM heat transfer over a sensor surface: A synthesis and characterization

Abstract

The peculiar characteristics of silver-capped iron oxide nanoparticles (AgFe₃O₄) make them very valuable in a range of sensing applications. These nanoparticles are a combination of iron oxide's (Fe₃O₄) magnetic characteristics and silver's (Ag) antibacterial, catalytic, and electrical ones. This study aims to investigate how silver-capped iron oxide nanoparticles affect heat transfer in the Cattaneo-Christov model (CCM) for sensor surfaces. Additionally, we conducted the synthesis and characterization of silver-capped iron oxide nanoparticles for the application study. Using similarity transformations, we may get the leading equations' self-similar structure. For each given velocity of a sensor surface carrying silver-capped iron oxide nanoparticles, we have found similar solutions to the problem. The numerical solutions to the self-similar nonlinear equations are shown in graphs and tables. These show how the temperature and velocity gradient change for different parameter values. The main conclusions that can be identified in the work include the assertion that the velocity profile becomes flatter as the squeeze flow index ($b$) parameter value rises. Furthermore, As the $f_0$ parameter is improved, the temperature of the fluid becomes more intense. The above-mentioned conclusions are highly relevant for the environment and biological applications of the results, primarily for those with an increased focus on the optimization of tracking the environment efficiency.
