      abstract     = {Poly(butadiene-ethylene oxide) (PB-PEO) block copolymers
                      form wormlike micelles in water. These structures can be
                      characterized over a very broad range of length. scales,
                      ranging from the contour and persistence length to the
                      core/corona diameter and the total aggregation number. Here
                      we use fluorescence microscopy, dynamic and static light
                      scattering and small angle neutron scattering to obtain
                      information on the full range of length scales, while
                      changing the solvent selectivity of the block copolymer by
                      varying the molar ratio of mixtures of N,N-dimethylformamide
                      (DMF) and water. We show that the wormlike micelles become
                      very small and flexible before a transition to spherical
                      micelles sets in decreasing the interfacial tension. We
                      calculated the free energy contributions for the different
                      species using the experimental input and confirmed that the
                      transition to spherical micelles is energetically favored.},
