The present relates to a combined hydrogen storage-compression unit suitable for the filling of high-pressure (350 bar and beyond) hydrogen vessels. It comprises a containment vessel filled with a hydrogen storage alloy, a heating system, a cooling system ...
Multiscale characterization of the hydrogenation process of silicon solar cell contacts based on c-Si/SiOx/ncSiCx(p) has been performed by combining dynamic secondary ion mass-spectrometry (D-SIMS), atom probe tomography (APT), and transmission electron mi ...
