Fig. 1From: Electron beam induced dehydrogenation of MgH2 studied by VEELSTEM bright field image of a typical nanocrystalline MgH2 particle, which is already dehydrogenated due to the impact of the electron beam. The red square indicates an area of 36 × 36 nm2 of the particle, from where the VEEL spectra are acquired with the CCD cameraBack to article page
