Abstract
The motive of this study is to explore the consequences of the Hall current and Ion-slip on the fully developed mixed convection flow of Casson nanofluid between two inclined concentric cylinders filled with gyrotactic microorganisms. In addition, the phenomena of heat and mass are examined under the impact of thermal radiation and activation energy, respectively. The walls of a cylinder are controlled by temperature jump and velocity slip conditions. Further, the Buongiorno nanoscale model is adopted for the formulation of fluid equations and then numerically treated by the MATLAB bvp4c technique. Graphs are drawn against the velocity, temperature, and motile density profiles. In all graphs and tables, the consequences of inclined and vertical magnetic fields with angles 45

and 90

are portrayed and illustrated respectively. It is also determined that the density of microorganism distribution declined when the Peclet number is augmented. To verify the accuracy of the findings, a graphical comparison is made with an already published work.
