“…During oxidation, the reverse effect is observed. It is known that several percent of C can be incorporated in the γ-Fe lattice, depending on the temperature of the system [49]. During oxidation, only limited FeO is formed (see Figure 2 and Figure S6 in the supporting information).…”

In this work, a spray-dried Fe-based oxygen carrier with an in situ generated Mg1-xAl2-yFex+yO4-support was investigated during packed-bed chemical looping operation with methane at 900°C. The evolution of the solid-state chemistry taking place in the oxygen carrier material was investigated in real-time with synchrotron X-ray diffraction while the spatial distribution of the phases was investigated using X-ray diffraction computed tomography (XRD-CT). These measurements revealed that some Fe-cations were systematically taken up and released from the spinel support. This take-up and release was shown to be strongly related with the oxidation state of the active phase. Although this take-up and release of Fe-cations decreased the amount of Fe-oxides active in the chemical looping process, the oxygen transfer capacity was still sufficiently high. The microstructure of the oxygen carriers along the length of the packed reactor bed was also investigated with scanning electron microscopy (SEM). The experiments indicate that the MgFeAlOx support with an extra Fe-based active phase is a promising material for oxygen carriers, as it forms a sustainable non-toxic, stable and green alternative to the typical Ni-based oxygen carriers for hydrogen generation by chemical looping.

Safety belts are one of the most significant elements of car equipment classified as passive safety. This paper provides a comparative material analysis of critical components of a trusted manufacturer's six-point harness used in motorsports racing with commercially available imitation belts. Despite the FIA certification labels, the imitation belts are characterized by extremely poor quality in the selection of materials for components such as the snap hooks and the locking sleeves in the central fastening mechanism, posing a real hazard to unaware belt users. At the same time, the results of the research are also intended to build consumer awareness of the risks associated with the purchase of passive safety equipment from unreliable sources or/and at discount prices, which entails real threats to life and health.
