Front Cover: Double‐layer hollow fiber: the inner layer of the fiber is made of a blend of polyethersulfone (PES) and sulfonated polyethersulfone (SPES) and the outer layer is made of a polystyrene‐block‐poly(4‐vinylpyridine) diblock copolymer (PS‐b‐P4VP). The fiber is fabricated by SNIPS process where an isoporous structure is formed on the surface of the fiber due to the self‐assembly of the block copolymer chains and the asymmetric substructure results from non‐solvent induced phase separation. Further details can be found in the article by N. Noor, J. Koll, M. Radjabian, C. Abetz, and V. Abetz* on page 414.
