The process of ion transfer in passivating film on iron containing high concentrations of mobile protons are investigated in acid sulfate solutions by virtue of chronoamperometric, capacity and ellipsometric methods.
For instance, larger molecular mass or different chemical composition of the label moiety might have an impact on the amount of collision energy absorbed by the precursor or it could influence mobile protons, which might in turn lead to disparate or more complex fragmentation patterns.
For the part of ionic conductivity, we characterize the unifying design scheme as one of the establishing strong anionicity on the host frameworks so as to facilitate the incorporation of potentially mobile protons or other cations in the porous domain.
This work suggests that a combination of guest molecules and microporous frameworks could afford highly mobile proton carriers in solids.
Mobile protons, such as those present in a small water molecule, take a relatively long time for their signal to decay in the detector plane and, as a result, the long T2 values produce a large signal on T2-weighted imaging.
Magnetisation transfer (MT) is a quantitative magnetic resonance imaging (MRI) technique, based on the exchange of magnetisation between protons in at least two pools: mobile protons and protons bound to macromolecules (Tofts et al., 2003).
Cortical bone is devoid of mobile protons and shows low signal intensity in all pulse MR sequences, whereas the medullary component has the appearance of yellow marrow.
