Liquid metal embrittlement to the fire was caused by the failure of a heat exchanger (cold box) inlet nozzle in the liquids recovery plant. The failure of the inlet nozzle was due to liquid metal embrittlement of the train B aluminium cold box by elemental mercury. Liquid metal embrittlement plays a central role in the novel "Killer Instinct" by Joseph Finder. In the film "Big Hero 6", Honey Lemon, voiced by Genesis Rodriguez, uses liquid metal embrittlement in her lab. Liquid metal embrittlement Liquid metal embrittlement, also known as liquid metal induced embrittlement, is a phenomenon of practical importance, where certain ductile metals
Liquid hydrogen The first synthesis of the stable isomer form of liquid hydrogen, parahydrogen, was achieved by Paul Harteck and Karl Friedrich Bonhoeffer in 1929. The two nuclei in a dihydrogen molecule can have two different spin states. Parahydrogen, in which the two nuclear spins are antiparallel, is more stable than orthohydrogen, in which the two are parallel. At room temperature, gaseous hydrogen is mostly in the ortho isomeric form due to thermal energy, but an ortho-enriched mixture is only metastable when liquified at low temperature. It slowly undergoes an exothermic reaction to become the para isomer, with enough energy released as
