Abstract:
... This comprehensive review paper compares the different methods developed experimentally to produce hydrogen by reacting aluminum and water. The alumina oxide layer which forms on the exterior surface of aluminum inhibits the reaction from taking place. Therefore, this paper presents a variety of techniques used to eliminate the oxide layer so that the reaction can continuously take place. The revi ...

Abstract:
... Aluminum alloys undergo permanent material property degradation that results in a reduced post-fire capacity of a structure. This degradation occurs at temperatures as low as 200 °C and is a function of both exposure temperature and duration. Material models have been previously developed that account for both temperature and duration but previous modeling efforts for aluminum structures have only ...
