Front Cover: The morphology of a sulfonated pentablock ionomer is shown to depend sensitively on the casting solvent(s) used in deposition. Images obtained from transmission electron microscopy and microtomography reveal that casting from a nonpolar solvent, cyclohexane, produces discrete ionic microdomains embedded in a nonpolar matrix. Alternatively, casting from a relatively polar solvent, tetrahydrofuran, results in the coexistence of alternating lamellae and nonpolar cylinders arranged on a hexagonal lattice in a sulfonated matrix. Further details can be found in the article by K. P. Mineart, X. Jiang, H. Jinnai, A. Takahara, and R. J. Spontak* on page 432.
