  • Shape-memory materials hold great potential for actuators and aims to improve them focus on increasing the maximum strain that they exhibit in response to a stimulus. Here the authors demonstrate a large shape-memory effect in bismuth ferrite, observing a maximum strain of up to 14%.

  • Ferroelastic switching in thin films is typically restricted by constraints from the substrate or occurs around twin-like domains. Here, the authors show reversible and non-volatile ferroelastic switching avoiding substrate constraints in layered-perovskite Bi_2WO_6 epitaxial films.

  • Researchers demonstrate a scheme that combines the high spatial resolution of full-field transmission X-ray microscopy (TXM) with high-spectral-resolution near-edge X-ray absorption fine structure (NEXAFS). The idea could lead to a wide range of new material studies that combine high-resolution spectroscopic techniques with nanoscale tomographic imaging.

  • Application of Molybdenum alloys is hindered by reduced ductility at lower temperatures. Here, the author shows improved ductility in a Mo alloy with irregular-shaped rare-earth La2O3 nanoparticles achieved via rotary-swaging, attributed to the amorphization of the oxide-matrix interface.

  • While H2 evolution from water may represent a renewable energy source, there is a strong need to improve catalytic efficiencies while maximizing materials utilization. Here, authors examine single-atom Pt on nickel-based heterostructures as highly active electrocatalysts for alkaline H2 evolution.

  • The residual strains in the mixed halide perovskite thin films and their effects on the solar cell devices are less understood. Here Zhu et al. study the impact of the gradient in-plane strain on the carrier dynamics of the strained perovskite films and optimize the device efficiency.

  • Double perovskite Cs2AgBiBr6 single crystals are used to make a sensitive X-ray detector. The device exhibits a high sensitivity of 105 µC Gyair −1 cm−2 and a low detection limit of 59.7 nGyairs−1, and demonstrates long-term operational stability.

  • Nematic electronic order is rare and its onset often indicates a phase transition. Here, Li et al. report a nematic superconducting state in Ba0.5K0.5Fe2As2 by measuring the angular dependence of the in-plane and out-of-plane magnetoresistivity.
