Solid-state NMR characterisation of the thermal transformation of a Hungarian white illite [PDF]

open access: yes, 2005
1H, 27Al, 29Si and 39K solid-state NMR are reported from a Hungarian illite 2:1 clay for samples heated up 1600 °C. This single-phase sample has a small amount of aluminium substitution in the silica layer and very low iron-content (0.4 wt%).

Effects of radial radio-frequency field inhomogeneity on MAS solid-state NMR experiments [PDF]

open access: yesMagnetic Resonance, 2021
Radio-frequency field inhomogeneity is one of the most common imperfections in NMR experiments. They can lead to imperfect flip angles of applied radio-frequency (rf) pulses or to a mismatch of resonance conditions, resulting in artefacts or degraded ...

Solid-State NMR Study of New Copolymers as Solid Polymer Electrolytes

open access: yesMagnetochemistry, 2018
We report the analysis of comb-like polymers by solid-state NMR. The polymers were previously evaluated as solid-polymer-electrolytes (SPE) for lithium-polymer-metal batteries that have suitable ionic conductivity at 60 °C.
