Mechanism of ion extraction

Despite the use of balancing mechanisms of ion extraction, for example, delayed extraction, larger inhomogeneities frequently found in slowly grown crystalline matrix preparations are known to influence the mass accuracies. The highly homogeneous sample surfaces achievable in ILMs can drastically reduce these problems upon conversion of the crystalline matrices into ILMs [45]. 

Molecular recognition is a central theme of supramolecular chemistry and biology As far as the mechanism of ion extraction or transport is concerned, it becomes clear that the surface of water, where extractant molecules accumulate, becomes a key border where ions can be captured. On the computational side, it is possible to address the question of ion recognition at the interface, using free energy perturbation calculations This is described in ref., for the Na / Cs" " discrimination by the calixC6 ligand ("L"). For this purpose, we defined a thermodynamic cycle...
