  Exciton polaron formation and hot-carrier relaxation in rigid Dion–Jacobson-type two-dimensional perovskites

  The detailed interplay between electronic and lattice dynamics in two-dimensional perovskite materials remains elusive. Here the authors establish the room-temperature polaronic nature of the excitons in two-dimensional Dion–Jacobson-type perovskites.

  Twistronics and the small-angle magic

  Understanding, at the atomic level, the effect of the stacking and twisting of different layered two-dimensional materials is a major challenge for the future of twistronics. Optical excitations evidence twist-angle-dependent whirlpool-shaped distortions in such materials.

  Insight into the effects of confined hydrocarbon species on the lifetime of methanol conversion catalysts

  The methanol-to-hydrocarbons reaction on zeolites produces olefins from many sources, but catalyst stability is a major challenge. Here, by combining operando measurements and simulations, the formation and identification of deactivating carbonaceous species throughout the reaction are achieved.

  Shaky lattices for light–matter interactions

  Impulsive Raman spectroscopy reveals how atoms are pushed into action by light absorption. The surprising sensitivity of this behaviour to the polaronic character of 2D perovskites opens up new avenues for tailored light–matter interactions.

  Enhanced by organic surfaces

  Nanostructured films of organic semiconductors are now shown to enhance the Raman signal of probe molecules, paving the way to the realization of substrates for Raman spectroscopy with molecular selectivity.

  Ultrafast energy- and momentum-resolved dynamics of magnetic correlations in the photo-doped Mott insulator Sr₂IrO₄

  The dynamics of the magnetic correlations after photo-doping Sr₂IrO₄ are studied through ultrafast time-resolved resonant inelastic X-ray spectroscopy. The timescales are found to depend on the dimensionality of the correlations.
