In 2021, the global production of ammonia was estimated at around 200 megatons, which makes ammonia the second-most produced chemical in the world. Among different ammonia synthesis routes, the most prevalent one is the Haber-Bosch process, occurring over the iron catalyst at high pressures (more than 150 bar) and high temperatures (more than 400⁰C). However, it has been recently demonstrated...
Hybrid implant materials consisting of a permanent Ti-based part combined with a degradable Mg part, where the Ti is used for its high strength while the temporary part is used for bone stimulation or drug delivery, are promising solutions to improve biocompatibility and stability of current implants. As Mg degrades hydrogen gas is released which ingresses into the Ti part, leading to changes...
Martensitic phase transitions are of utmost importance for structural and smart materials such as for example steels and shape memory alloys, respectively. Apart from destructive, local or integral methods neutron imaging techniques have been explored to spatially map and quantify martensitic phase fractions in such materials. Such techniques include neutron Bragg edge and neutron dark field...
The magnetic flux guidance in an electric engine is achieved by introducing cutouts in the electrical steel (ES) sheets that make up its core. However, these cutouts create thin structures, reducing the mechanical strength of the ES sheets and limiting the achievable rotational speed and therefore the energy efficiency of the engine.
Residual stress in ES sheets reduces the mobility of...
