      abstract     = {Self-assembled grains of mixed colloids have been
                      synthesized using evaporation induced self-assembly (EISA)
                      by spray drying. We demonstrate using electron microscopy
                      and small-angle neutron scattering experiments that buckling
                      driven sphere to deformed-doughnut like morphological
                      transformation in such a process can be arrested by proper
                      tuning of the surface charge on the colloidal components.
                      The buckling amplitude diminishes with a reduction in
                      stabilization force between the colloidal particles. It is
                      established that such arrest of morphological transformation
                      is related to an effective exposure of the surface of softer
                      component at gas-liquid interface. Scattering experiments
                      confirm relatively more compact structure of the non-buckled
                      grains compared to that of the buckled grains. A plausible
                      mechanism regarding the arrest of morphological
                      transformation by surface charge tuning is illustrated.},
