Abstract:<div>Clay minerals in contact with aqueous bulk reservoir undergo a geological transformation of swelling or shrinking by exchanging interstitial cations. For geological applications, it is crucial to understand the stability of these layered materials. Here, we demonstrate that a sub-angstrom change in the interstitial cation size with similar hydration characteristics is enough to destabilize the optimum spacing of layered materials. We used molecular simulations to investigate the stability of water l… Show more
