  • In some materials electrons can behave hydrodynamically, exhibiting phenomena associated with classical viscous fluids. In this theory work, the authors show that the symmetries of the crystal lattices in which the electrons reside can lead to additional unique hydrodynamic effects.

  • Surface controls nanocrystal growth, but atomic-scale hard-soft interfaces are hard to measure. Here, the authors develop electron microscopy methods to reveal the position of metal adatoms and surfactant counterions on gold nanocuboid surfaces.

  • Here, advanced scanning transmission electron microscopy techniques are used to image the atomic structure at the interface between 2D MoS2 and 3D Au nanoislands, revealing a moiré superlattice and illustrating the potential for (opto-)electronic moiré engineering at the 2D/3D interface.

  • 4D-scanning transmission electron microscopy uses diffractive imaging for structural studies. Here, authors study single particle cryo-EM protein samples at up to 5.8 Å resolution, using 4D-STEM and ptychography data processing.

  • When interactions between electrons in a material are strong, they can start to behave hydrodynamically. Spatially resolved imaging of current flow in a three-dimensional material suggests that electron–electron interactions are mediated by phonons.

  • A good way to identify microscopic conduction regimes where current flow deviates from Ohm’s law is still lacking. Here, the authors identify Sondheimer oscillations as a quantitative probe of the length scale of relaxing electron scattering in studying the non-ohmic electron flow of WP2 crystals.

  • Controlled delivery of neuromodulators in the brain might improve the understanding of the molecular basis of behaviour. In this letter, magnetic liposomes injected in deep brain regions release small molecules under remote magnetic stimulation, activating specific neuronal circuits in freely moving mice.

  • Electrons in strongly interacting materials can flow collectively, exhibiting hydrodynamic phenomena such as viscous flow. This Review highlights recent experimental advances, including high-quality materials growth, that have enabled these observations and surveys the spatially resolved theoretical frameworks necessary to interpret and predict these phenomena.
