SCIENTIFIC GOALS FOR THE ANTICIPATED ACE-T9-2 EXPERIMENTS ARE TWO-FOLD. FIRST WE WOULD LIKE TO CONTINUE TO STUDY THE FOLDING DYNAMICS OF THE FABRICATED COLLOIDAL CHAINS IN THREE DIMENSIONS AND UNDER THE MICROGRAVITY ENVIRONMENT. THE EXPERIMENTAL MEASUREMENTS WILL BE COMPARED WITH THEORIES FOR POLYMERIC MOLECULES AND NUMERICAL SIMULATIONS BASED ON FLUCTUATING HYDRODYNAMICS. SECOND WE WILL PERFORM EXPERIMENTS TO UNDERSTAND THE 3D ASSEMBLY BETWEEN TWO-DIMENSIONAL MICRO WHEEL-LIKE COLLOIDAL CLUSTERS INDUCED BY DEPLETION INTERACTIONS.
