  Analyzing microstructure relationships in porous copper using a multi-method machine learning-based approach

  Material properties prediction from a given microstructure is important for accelerated design but a comprehensive methodology is lacking. Here, a multi-method machine learning approach is utilized to understand the processing-structure-property relationship for differently processed porous materials.

  Three-dimensional distribution of individual atoms in the channels of beryl

  Single atom detection in nanoporous materials is challenging due to their sensitivity to electron irradiation. Here, the three-dimensional atomic occupancy of natural beryl is quantitatively analysed using high-angle annular dark-field imaging in a scanning transmission electron microscope and statistical analysis.

  Algorithm for fast evaluation of in-plane fiber orientation in reinforced plastics using light microscopy images

  The orientation of reinforcing fibers in composite materials is key to their performance, yet is hard to determine as fibers are buried within a sample. Here, an algorithm allows for the rapid determination of in-plane fiber orientation, based on microscopy images of adjacent regions.

  Shear band formation during nanoindentation of EuB₆ rare-earth hexaboride

  Rare-earth hexaborides are of interest for their pressure-induced phase transformations, but further understanding is needed regarding their failure mechanisms. Here, nanoindentation of EuB₆ causes dislocation-mediated shear band formation, driven by the breaking of boron-boron bonds.

  Tunable metal contacts at layered black-arsenic/metal interface forming during metal deposition for device fabrication

  In 2D materials devices, understanding interfacial reactions in the formation of metal contacts is important for tuning their properties. Here, electron microscopy reveals the formation of an intermetallic contact layer, characterized by an efficient edge-type charge transfer, when nickel, chromium, or titanium is deposited onto black-arsenic films.

  Sensitizer-enhanced two-photon patterning of biomolecules in photoinstructive hydrogels

  Proteins can be patterned in photoresponsive hydrogels by the application of light. Here, a two-photon lithography-based approach allows for the 3D patterning of proteins with micrometer precision, demonstrated for a photoinstructive hydrogel and relevant to a range of proteins.

  Charged domain boundaries stabilized by translational symmetry breaking in the hybrid improper ferroelectric Ca_3–xSr_xTi₂O₇

  Charged domain walls in ferroelectrics are interesting as they may enhance electrical conductivity. Here, atomic-resolution imaging of Ca_3–xSr_xTi₂O₇ reveals that charged domain boundaries are stabilized by an out-of-phase translational shift of crystallographic domains and that Sr ions accumulate at the boundaries.

  A transparent waveguide chip for versatile total internal reflection fluorescence-based microscopy and nanoscopy

  Total internal reflection fluorescence microscopy typically relies on opaque optical waveguides, compatible only with upright microscopes. Here, a versatile approach is reported that uses CMOS-compatible transparent chips, demonstrated for the imaging of synthetic and biological samples, including super-resolution applications.

  Improved gravimetric energy density and cycle life in organic lithium-ion batteries with naphthazarin-based electrode materials

  Replacing metal electrodes in lithium-ion batteries with organic materials reduces environmental impact and might lead to high gravimetric capacity. Here, organic electrodes containing a naphthazarin-dimer skeleton achieve an initial capacity of 416 mAh g⁻¹ and energy density of 1.1 Wh g⁻¹ in a lithium-ion battery.
