This week, A. Corma et al. review the synthesis and catalytic properties of multipore zeolites. What does molecular traffic control mean in this context? In a Highlight, A. Simonneau and M. Oestreich discuss the hydrogen transfer chemistry of alkenes with an emphasis on total synthesis.

In the Communications section, G. Storch and O. Trapp report on the temperature control of bidirectional enantioselectivity in catalyzed asymmetric hydrogenation (see picture). C. M. Niemeyer et al. monitored the reversible reconfiguration of DNA origami nanochambers by single-molecule FRET. D. Yan et al. prepared ultrathin copolymer nanotubes with tunable surfaces. D. B. Janssen et al. describe enantioselective enzymes obtained by computational design and in silico screening.
