TL;DR: A combination of scanning transmission electron microscopy, electron energy loss spectroscopy, and ab initio calculations reveal striking electronic structure differences between two distinct single substitutional Si defect geometries in graphene.

TL;DR: This review covers the theoretical principles behind the ELNES technique, the experimental procedures necessary to acquire good ELNES spectra, including potential artefacts, and gives examples relevant to materials science.

TL;DR: In contrast to the solid-state structures of individual compounds, arene-perfluoroarene face-to-face stacking and C-H-F-C in-plane interactions dominate the solid state structure of 1∶1 co-crystals of 1,4-bis(phenylethynyl)-tetrafluorobenzene 1b and 1, 4-bis-(pentafluorophenylethyl)- benzene 1c, with this supramolecular aggregation leading to the stabilisation of a nematic liquid crystalline phase RE
