To study the nature of the nonexponential ionic hopping in solids a pulse sequence was developed that yields four-time stimulated-echo functions of previously inaccessible spin-3/2-nuclei such as 7 Li. It exploits combined Zeeman and octupolar order

In anticipation of using fluctuations in the nuclear dipolar and quadrupolar interaction as a probe of lithium ion motion in lithium borate glasses, the static values of these interactions were measured using a variety of echo techniques. The static

Two methods have been used for examination of transport of charge in gels soaked with DMF and containing dissolved polyoxometallates. The first method is based on the analysis of both Cottrellian and steady-state currents and therefore is capable of

The influence of surface-modified Al2O3 particles on the formation of different ionic aggregates in poly (ethylene glycol) methyl ether (PEGME)–LiClO4 and poly (ethylene oxide) dimethyl ether (PEODME)–LiClO4 electrolytes is discussed. Three indep

It has been previously shown that the addition of surface-modified Al 2 O 3 results in the enhancement of conductivity for systems based on poly(ethylene glycol)–alkali metal complexes. The filler Al 2 O 3 surfaces are neutral, acidic or basic. Thi

Polyoxometalate additives were entrapped in the poly(methyl methacrylate) (PMMA) and poly (glycidyl methacrylate) (PGMA) swollen with polar aprotic solvents. Conductivities of 3×10−3 S cm−1 at 25 °C and 5.6×10−3 S cm−1 at 90 °C were measu

Two dimensional deuterium NMR measurements are reported for three different onium salts (CH3)3SeNO3-d3, (CH3)3TeI-d3, and (CH3)3SI-d9. In these molecular solids with the general structure (CH3)3E+X-, three methyl groups are attached to the E atom. Th
