Graphical Abstract

A pyrene-linked protein cavity attracts two substrate molecules like the scent of a flower attracts butterflies. In their Communication on page 13618 ff., A. Onoda, T. Hayashi, and co-workers demonstrate that a polycyclic pyrene moiety linked within the rigid protein scaffold of the β-barrel of nitrobindin acts as a platform to provide an aromatic interaction with a substrate. An asymmetric Diels–Alder reaction between azachalcone and cyclopentadiene proceeds smoothly with high stereoselectivity within the reaction scaffold.

NMR Spectroscopy

In their Communication on page 13590, M. Ernst, B. H. Meier, and A. A. Smith examine potential pitfalls for the NMR analysis of protein dynamics and propose the use of dynamics detectors to characterize different ranges of correlation times.

Light Olefins

Pérez-Ramírez et al. show in their Communication on page 13670 ff. the outstanding performance of EuOCl for the production of light olefins from ethane and propane by oxychlorination chemistry. The system features high activity, selectivity, and stability.

Hydrogen Evolution Reaction

Single Pt atoms have been synthesized on CoP-based nanotube arrays by potential cycling. In their Communication on page 13694 ff., X. J. Liu, J. Luo et al. show the resulting materials have high activity in the hydrogen evolution reaction (HER).
