Dynamic nuclear polarisation NMR of nanosized zirconium phosphate polymer fillers.
Surface functionalisation with organic modifiers of multi-layered zirconium phosphate (ZrP) nanoparticles used as polymer fillers can be directly probed by dynamic nuclear polarisation NMR, which provides unambiguous evidence of the presence of P-O-C chemical bonds at the surface of the ZrP layers, thereby confirming successful functionalisation.
متن کاملNMR Study of the Solid Electrolyte Interface on a High Performance Lithium Metal Anode
Introduction: Li metal is an ideal anode material due to its low density (0.534 g cm -3 ), the lowest negative electrochemical potential (-3.040 V vs. standard hydrogen electrode) and extremely high theoretical special capacity (3860 mAh g -1 ), which is ten times as high as that of carbonaceous materials. However, several seemingly insurmountable barriers, including limited Columbic efficiency...
متن کاملDynamic Nuclear Polarisation in P-doped Silicon by Microwave Ultrasonics
We have investigated the dynamic nuclear polarisation (DNP) of 298i nuclei in highly doped silicon single crystals. The saturation of the electronic Zeeman levels in a magnetic field of 3.3 kG at 1.60)( was obtained using microwave ultrasonics of about 9 GHz. The ultrasonic waves were generated in a cavity by means of a transducer consisting of a thin film of CdS evaporated on the polished surf...
متن کاملOxygen-17 dynamic nuclear polarisation enhanced solid-state NMR spectroscopy at 18.8 T.
We report 17O dynamic nuclear polarisation (DNP) enhanced solid-state NMR experiments at 18.8 T. Several formulations were investigated on the Mg(OH)2 compound. A signal enhancement factor of 17 could be obtained when the solid particles were incorporated into a glassy o-terphenyl matrix doped with BDPA using the Overhauser polarisation transfer scheme whilst the cross effect mechanism enabled ...
