  • This work challenges the view of nucleation governing halide perovskite grain morphology, showing that most additives act post-nucleation by boosting ion mobility across grain boundaries, triggering grain coarsening, similar to post-processing effects.

  • The existence of a crystalline precursor is key to perovskite film formation, but the precise chemistry of the precursor and its transformation into perovskite are poorly understood. Here, the authors identify the crystal structure and conversion chemistry of the precursor for PbCl2-derived methylammonium lead iodide perovskites.

  • The diversity of perovskite compositions has led to ambiguity in their representation and impose challenges for data mining and machine learning applications. Here, the authors propose a set of guidelines and a JSON schema for standardized description and reporting of perovskite compositions.

  • The Yersinia YaxAB system is a pore-forming toxin of so far unknown structure. Here authors present X-ray and cryo-EM to structures of individual subunits and of the YaxAB pore complex, and find that YaxA binds to membranes first and recruits YaxB for subsequent oligomerization.

  • Metal-halide perovskites are promising photovoltaic materials, but fundamental questions remain open due to their structural complexity. Here the authors show, by correlated microscopy and spectroscopy methods, that epitaxially induced lattice distortions drive a size dependent modulation of the bandgap in a homogeneous nanowire system.

  • Radiation damage in biology is largely mediated by radicals and low-energy electrons formed by water ionization and extensive, localized water ionization can be caused by ultrafast processes following the core-level ionization of hydrated metal ions. Now it has been shown that, for Al3+ ions, relaxation occurs via sequential solute–solvent electron transfer-mediated decay.

  • Electron-transfer-mediated decay (ETMD) is a recently discovered type of electronic relaxation that involves the refilling of a core hole by an electron from a neighbouring species. It has now been observed in LiCl solution, when previously it had only been seen in rare-gas clusters. Spectra generated during ETMD are observed to be sensitive to the immediate environment of the initially ionized ion.

  • Understanding crystal phase transition in materials is of fundamental importance. Using luminescence spectroscopy and super-resolution imaging, Dobrovolsky et al. study the transition from the tetragonal to orthorhombic crystal phase in methylammonium lead triiodide nanowires at low temperature.

  • Defining and revising best practices for accurate measurements and data reliability and quality checks is a continuous effort for the commercialization of perovskite solar cells. Here, the authors discuss the systematic discrepancy between the short circuit current and integrated quantum efficiency.

  • Despite the importance of small RNA–mediated silencing, no structural information exists for complexes of known function. Using single-particle EM, the structure of the minimal functional unit for RNAi in humans (AGO2, Dicer and TRBP) is now presented.
