AB - The transport of energy via nanoparticles remains a crucial research domain  in modern technological and industrial advancements. This study investigates  the boundary-driven Maxwell nanofluid-flow over a magnetized stretched sheet  while incorporating the Cattaneo-Christov heat flux model, which versions  for thermal relaxation effects. Unlike the classical Fourier heat conduction  model, the Cattaneo-Christov formulation considers thermal interval, making  it more suitable for high speed and microscale heat transfer applications.  The convection process is analyzed within the framework of mass and energy  transportation. The governing eqs remain converted into a non-dimensional  form, and the bvp4c numerical scheme is employed to obtain solutions.  Graphical illustrations provide insights into the effect of key parameters  on temperature, concentration, and microorganism profiles. A rise in the  thermal relaxation parameter slows down the heat transfer process, reducing  the temperature distribution and enhancing thermal resistance. The  concentration profile initially rises with an increasing relaxation  parameter due to rapid structural adaptation but later declines as reaction  kinetics dominate. Additionally, an increase in activation energy, E, lowers  the concentration of reactants due to higher energy requirements for  diffusion and reaction processes. The density of microorganisms is  augmented with increasing Deborah and magnetic number values, while  thermophoresis and bioconvection effects contribute to temperature  enhancement. These findings provide valuable insights into heat and mass  transfer mechanisms in nanofluid systems, with potential applications in  industrial, biomedical, and energy transport sectors.
