Atomically thin quantum light-emitting diodes

Nature Communications, 2016
Atomically thin transition metal dichalcogenides hold promise as scalable single-photon sources. Here, the authors demonstrate all-electrical, single-photon generation in tungsten disulphide and diselenide, achieving charge injection into the layers ...

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.
