“…As evidenced throughout the present article, FFC NMR relaxometry overcomes all the aforementioned problems, although it lacks in resolution and cannot provide structural information concerning the chemical nature of the investigated environmental system. 6 In addition, model theories for FFC NMR relaxometry have been developed mainly for polymer dynamics such as lipids, proteins, and carbohydrates, 5,6,44,59,60 material science, 53,61 -63 and contrast agents for magnetic resonance imaging applications. 64,65 For this reason, FFC NMR relaxometry should be supported by results from other analytical techniques when it is applied in environmental field.…”
