      Nanofluids can be engineered as per requirements and have applications in microelectronic, therapeutic activities, hybrid-mechanical machineries, aeronautics zones, thermonuclear storehouses, shielding of miscellaneous engines etc. Here, the aspects of new mass flux theory in magneto Carreau nanofluid with convectiveand variable connectivity have been studied. Additionally, nonlinear properties of mixed convection are examined. The shear thinning–thickening properties are analysed by utilising bvp4c algorithm for influential variables.The fluid temperature increases with thermophoresis and variable conductivity parameters. The outcomes of thermophoresis and Brownian motion parameters have conflicting influences on concentration field.

      Recently, nanotechnology, especially the phenomena affecting the properties of flow and heat transport of nanofluid, has attracted considerable attention of researchers. In this study, the influence of Joule heating and chemical reaction in magnetite Carreau nanofluid has been elaborated considering the properties of radiation and convective phenomena. Additionally, the variable wall temperature and wall concentration have been reported. The bvp4c algorithm has been considered for solution progression. The influential variables are depicted graphically. The result reports that the temperature field increases for Eckert and magnetic numbers. The other output increases the concentration field for chemical reaction factor and decays for Brownian factor. Furthermore, comparison tablesare given to show that our results agree with the results from earlier studies.
