Ab initio calculations were performed to study the stability of various anhydrous and monohydrated complexes of Mg2+ with pyrophosphates and orthophosphates at the self-consistent-field (SCF) and second-order perturbation ...

Using a simple model it is shown that the cost of constraining a hydrated potassium ion inside a narrow nanopore is smaller than the cost of constraining the smaller hydrated sodium ion. The former allows for a greater ...
