  • Electrocatalyst degradation driven by oxidation is a major barrier to a sustainable energy society. Here, the authors study the oxidation of Pt(111), a prominent model system, under oxygen evolution conditions, resolving self-limiting layer-by-layer growth of a sub-nanometer disordered PtO2 film.

  • Infinite-layer nickelates are of interest for exploration of unconventional superconductivity. Here, grazing-incidence x-ray diffraction of PrNiO2+x reveals an unusual in-plane period-six and out-of-plane period-four symmetry upon in-situ annealing, indicating a giant unit-cell superstructure.

  • Lead halide perovskite nanocrystals show bright and colour-pure emission in the visible range, which can be tuned by nanocrystal size and composition. Here authors present the formation mechanisms of anisotropic lead halide perovskite nanocrystals, 1D nanorods and 2D nanoplatelets, by combining in situ X-ray scattering and photoluminescence spectroscopy.

  • The competition between the formation of different phases and their kinetics need to be clearly understood to make materials with on-demand and multifaceted properties. Here, the authors reveal, by a combination of complementary in situ techniques, the mechanism of a Cu-Zr-Al metallic glass’s high propensity for metastable phase formation, which is partially through a kinetic mechanism of Al partitioning.

  • High-resolution, low-dose images of biological objects were obtained in a new method using photons of 60 keV. The dose was thousands of times lower than conventional methods, overcoming the previous limitations set by radiation damage to the sample.
