L’acier au bore est particulièrement approprié aux applications de l’industrie automobile. Il est attractif car il réduit le poids des véhicules et améliore la sécurité des passagers Il est essentiel

An ORNL-led team used neutrons to observe the AAT enzyme, a vitamin B6-dependent protein, and found that the chemical reaction occurred only in one active site. Nuclear scattering length density maps
