“…However, for manganese sulfide (MnS), the most favorable trapping site is the sulfur atom with E b = 1.28 eV compared with E b = 0.88 eV for the manganese atom (Mn). These results follow the trend in earlier results reported in the literature [20,39]. In the last section, we discuss the effect of the layer on the trapping capacity of the carbides.…”

“…In addition, it is well known that limited hydrogen diffusion may be sufficient to provoke a failure. Numerous studies have also found that the addition of microalloying elements (Nb, Ti, V, and Mo) might improve the HE resistance of steel [20]. In addition, metal carbide (MC) nanoprecipitates not only optimize the microstructure and improve the mechanical properties but also increase the hydrogen trap density in high-strength martensitic steels to improve HE resistance [16].…”

This study uses plane wave density functional theory (DFT) to investigate the effect of certain metal carbides (Niobium carbide, Vanadium carbide, Titanium carbide, and Manganese sulfide) on hydrogen embrittlement in pipeline steels. Our results predict that the interaction of hydrogen molecules with these metal carbides occurs in the long range with binding energy varying in the energy window [0.043 eV to 0.70 eV].In addition, our study shows the desorption of H2 molecules from these metal carbides in the chemisorptions. Since atomic state hydrogen interacts with NbC, VC, TiC, and MnS to cause embrittlement, we classified the strength of the hydrogen trapping as TiC + H > VC + H > NbC + H> MnS + H. In addition, our study reveals that the carbon site is a more favorable hydrogen-trapping site than the metal one.

“…Hence, there is a necessity for processes to maximize quality and yield while minimizing consumption and waste. Processes that are more indiscriminate in the quality or nature of the input feedstocks yet capable of producing reasonable quality outputs (like the Fischer–Tropsch technology for the production of liquid fuels from simple gases , [ 6,7 ] see Figure ) would win over processes that demand high purity of inputs or very complex processing environments to deliver a comparable, be it a better product that fulfils the same function. [ 8,9 ] Ideally, of course, we would like to develop process that deliver on all fronts.…”

Inhospitable, inaccessible, and extremely remote alike the famed pole of inaccessibility, aka Point Nemo, the isolated locations in deserts, at sea, or in outer space are difficult for humans to settle, let alone to thrive in. Yet, they present a unique set of opportunities for science, economy, and geopolitics that are difficult to ignore. One of the critical challenges for settlers is the stable supply of energy both to sustain a reasonable quality of life, as well as to take advantage of the local opportunities presented by the remote environment, e.g., abundance of a particular resource. The possible solutions to this challenge are heavily constrained by the difficulty and prohibitive cost of transportation to and from such a habitat (e.g., a lunar or Martian base). In this essay, the advantages and possible challenges of integrating Fischer–Tropsch, artificial photosynthesis, and plasma catalysis into a robust, scalable, and efficient self‐contained system for energy harvesting, storage, and utilization are explored.
