  • Rare-earth permanent magnets are engineered with a complex microstructure of composition and phase, grains and grain boundaries, and it is this complex structure which leads to the magnetic performance. Here, Giron and coauthors, through thorough microstructural analysis, demonstrate that the grain microstructure, not grain boundaries, are primarily responsible for optimal magnetic properties.

  • Two-dimensional pseudocapacitors may benefit portable electronic devices but require improved energy and power densities. Here, the authors achieve high volumetric capacitance in ultrathin films with oxygen vacancies that enhance electron conduction and intercrystallite water that promotes proton conduction.

  • Oscar Recalde-Benitez and colleagues report a FIB-based sample preparation process to limit current leakage during operando TEM experiments, thus improving the accuracy of device nanocharacterization under operating conditions. The methodology results in leakage currents that are small compared to device currents, which enables the analysis of operating stack devices inside the microscope.
