AB  - The origin of the buckling of micrometer-sized colloidal droplets during 
      evaporation-induced self-assembly (EISA) has been elucidated using electron 
      microscopy and small-angle neutron scattering. Doughnut-like assembled grains 
      with varying aspect ratios are formed during EISA at different physicochemical 
      conditions. It has been revealed that this phenomenon is better explained by an 
      existing hypothesis based on the formation of a viscoelastic shell of 
      nanoparticles during drying than by other existing hypotheses based on the 
      inertial instability of the initial droplets and hydrodynamic instability due to 
      thermocapillary forces. This conclusion was further supported by the arrest of 
      buckling through modification of the colloidal interaction in the initial 
      dispersion.
