Mass generation of scrap tires presents a major challenge for environmental safety, however, their upcycling into carbon-based nanomaterials by the virtue of pyrolysis treatments can open up new windows for energy conversion and storage technologies in the context of the circular economy. Herein, we report the synthesis of Fe-N-C oxygen reduction reaction (ORR) electrocatalyst for fuel cell (FC) applications using carbonaceous char derived from scrap tires through microwave-assisted pyrolysis (MAP). The char obtained from MAP was activated with potassium hydroxide and then pyrolyzed at a high temperature to fabricate Fe-N-C after mixing with iron and nitrogen precursors. Finally, the developed Fe-N-C was ball-milled and acid-etched for homogenization and leaching of iron oxide nanoparticles. In this study, structural evaluation during each synthesis step was elucidated and correlated with the ORR activity in all three pHs i.e. acidic, neutral, and alkaline. Moreover, the effect of electrocatalyst loading on ORR kinetics was also analyzed using two different loadings (0.2 and 0.6 mg cm−2) on the rotating ring disk electrode (RRDE). The developed Fe-N-C demonstrated encouraging onset potentials of 0.881, 0.822, and 0.936 V vs RHE in acidic, neutral, and alkaline conditions, respectively. Whereas the ORR activity was slightly reduced after the milling-etching step. Lower peroxide yield together with a tetra-electronic reduction of oxygen was witnessed in acidic and neutral conditions, however, peroxide production was increased in the alkaline medium.

Recent natural and man-made disasters highlight that a more resilient approach to preparing for and dealing with such events is needed. To address this challenge, the main objective of the research and innovation H2020 project DARWIN is the development of European resilience management guidelines for Critical Infrastructures (CI). Based on a systematic literature survey with a world-wide scope and prioritization of resilience concepts, the guidelines have been developed taking into account everyday operations, contingency plans, training, etc. This paper describes insights gained from the adaptation of these guidelines in the domains of Air Traffic Management (ATM) and Healthcare (HC). A collaborative and iterative process has been defined involving relevant experts and practitioners. To ensure transnational, cross-sector applicability and uptake, a Community of Crisis and Resilience Practitioners (DARWIN DCoP) has been involved. The preliminary results indicate that a big step has been taken in moving from the resilience theory to practice
