Abstract:The synthesis of kinetically “frozen”
metastable
nanostructures remains elusive. This limitation has severely restricted
the current paradigms in materials discovery. We overcame this challenge
by phase-stabilizing unusually hyperoxidized and metastable amorphous
aluminum oxide (a-AlO
x
; 2.5 < x ≤ 3.5) nanostructures. Specifically, we employed
laser ablation synthesis in solution (LASiS) as a one-pot nonequilibrium
technique to achieve this pivotal advancement. Structural and compositional
characterizations o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
