In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy
Journal of Synchrotron Radiation, EarlyView.For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

Meteoritics &Planetary Science, EarlyView.Abstract This study documents micro‐ to nanoscale observations of primary nebular and secondary parent body iron sulfides in the CR1 GRO 95577. Despite the extensive alteration of the bulk sample, some primary sulfides managed to avoid alteration, having originally formed in the solar nebula during chondrule formation by either fission‐sulfidization or
