TL;DR: In this article, the homogenization effect revealed by the microstructure simplification and chemical-segregation reduction leads to the decreased work function variations and the improved corrosion resistance of the AlxCoCrFeNi high-entropy alloys.

TL;DR: The mechanical origin of the twin domain contrast observed with piezoresponse force microscopy in methylammonium lead triiodide is unveiled and an interplay of ferroic properties and chemical segregation on the optoelectronic performance of hybrid organic–inorganic perovskites is revealed.

TL;DR: In this article, the microstructural evolutions with the increased Al content in the alloys are characterized by SEM, TEM, EDS and EBSD, showing that by increasing the Al content, the microstructure changes from single solid-solution to multi-phases, leading to the segregations of elements.

TL;DR: The development and implementation of electrochemical force microscopy (EcFM) is described to probe local bias- and time-resolved ion dynamics and electrochemical processes at the solid-liquid interface and is established as a force-based imaging mode, allowing visualization of the spatial variability of sample-dependent local electrochemical properties.

TL;DR: Current progress in multidimensional scanning probe microscopy techniques based on band excitation time and voltage spectroscopies are reviewed, including discussions on data acquisition, dimensionality reduction, and visualization, along with future challenges and opportunities for the field.
