      abstract     = {We assess the possibility of shear banding of semidilute
                      rod-like colloidal suspensions under steady shear flow very
                      close to the isotropic-nematic spinodal, using a combination
                      of rheology, small angle neutron scattering, and laser
                      Doppler velocimetry. Model systems are employed which allow
                      for a length and stiffness variation of the particles. The
                      rheological signature reveals that these systems are
                      strongly shear thinning at moderate shear rates. It is shown
                      that the longest and most flexible rods undergo the
                      strongest shear thinning and have the greatest potential to
                      form shear bands. Although we find a small but significant
                      gradient of the orientational order parameter throughout the
                      gap of the shear cell, no shear banding transition is
                      tractable in the region of intermediate shear rates. At very
                      low shear rates, gradient banding and wall slip occur
                      simultaneously, but the shear bands are not stable over
                      time.},
