The Reliability of a Tunnel Boring Machine [PDF]
Greater levels of complexity in tunnelling with Tunnel Boring Machine (TBM) allow higher chances of fail-ures that may increase the potential hazardous risks. This paper presents the results of a study on TBM reliability using risk analysis.

Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

In Situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio
The rocket propellant methane can be produced on Mars by in situ resource utilization. The H2/CO2 ratio is decisive, and excess H2 is favored for providing sufficient propellant purity. The operation mode—with or without recycling of unreacted reactants—depends on the resource availability of the selected landing site. Abstract For return missions from
