Confocal Raman observation of the efflorescence/deliquescence processes of individual NaN[O.sub.3] particles on quartz
Article Abstract:
The structural changes of bulk NaN[O.sub.3] solutions with molar water-to-solute (WSRs) of 54.0 - 12.3 and[NaN[O.sub.3] droplets (10-100 um) with WSRs of 9.5 - 1.0 on a quartz substrate is studied using confocal Raman spectroscopy. It is concluded that in bulk NaN[O.sub.3] solutions with WSR = 54.0 - 12.3, free [N[O.sub.3].sup.-] and solvent-separated ion pairs are dominative and contact ion pairs between [Na.sup.+] and [N[O.sub.3].sup.-] are formed for NaN[O.sub.3] droplets with WSR=9.5 - 6.0.

Dynamics of alkyl ammonium intercalants within organically modified montmorillonite: Dielectric relaxation and ionic conductivity
Article Abstract:
The low-frequency dynamic characteristics of alkyl quaternary ammonium exchanged montmorillonite (SC20A) are investigated to determine the correlation between temperature-dependent changes in the interlayer structure and collective mobility of the surfactant. Overall, SC20A displayed features of alternating current universally, including time-temperature superposition, common in other types of disordered ion-conducting media.
