Among the three inequivalent fluorides in tysonite CeF3(F1, F2, and F3 in the ratio of 12:4:2 per unit cell), we show by 19F solid-state NMR that F1 is solely responsible for the ion conductivity in Ce1-xSrxF3-x(x = 0.001) at 0 °C. It is further s...

There has been a long-standing controversy over ion conducting pathways in tysonite. To unravel the pathways in CeF3, high-resolution MAS NMR spectra of 19F in CeF3 at −40–240 °C are analyzed on the bases of the calculated dipolar coupling tensor ...
Electrochemical impedance spectroscopy (EIS) enables the examination of the electrochemical nature of electrodes and electrochemical cells by applying an alternating voltage (or current) and measuring the resulting current (or voltage). The resist...
Electrochemical impedance spectroscopy (EIS) is widely used for the analysis of various electrochemical devices, as it can quantitatively evaluate the main kinetic parameters related to electrochemical phenomena by analysis using equivalent circui...
