- ... ¹H fast field-cycling (FFC) NMR relaxometry was applied for the first time to monitor the state of water during the hydration reaction of MgO and silica that leads to the formation of magnesium silicate hydrate (M-S-H), the binder phase of innovative cements with promising applications in the containment of radioactive waste. To this aim, water proton longitudinal relaxation rates (R₁ = 1/T₁) were ...

- ... Longitudinal and transverse relaxivities of solid lipid nanoparticles loaded with superparamagnetic iron oxide nanoparticles (SPION-SLNs) were thoroughly investigated with the aim of understanding the main parameters regulating the potential negative contrast properties of these systems. In particular, the longitudinal relaxivity (r₁) of water protons in the 10 kHz to 35 MHz frequency range was de ...
