Title: Anomalously low activation energy of nanoconfined MgCO3 precipitation

Abstract

In this work, magnesite (MgCO3) precipitation within the nanoconfined space of adsorbed H2O films (~5 monolayers) was determined to have an apparent activation energy of only 36 ± 6 kJ mol–1, suggesting that Mg2+ under nanoconfinement adopts a hydration configuration that mimics that of aqueous Ca2+, at least energetically, if not also specifically in hydration structure.
