Intrinsic paramagnetic defects probe the superionic phase transition in mechanochemically synthesized AgI nanocrystals
Article Abstract:
Electron paramagnetic resonance (EPR) of two intrinsic paramagnetic centers generated by soft mechanochemistry of Ag and I to yield zinc blende gamma-AgI nanoparticles is used to investigate the gamma-alpha superionic phase transitions in AgI. The EPR study together with high-temperature electronic conductivity behavior demonstrates that the creation of electronic defects is essential for the formation of gamma-AgI nanoparticles in a near-equilibrium process such as the mechanochemical reaction (MCR).

On the origin of a permanent dipole moment in nanocrystals with a cubic crystal lattice: Effects of truncation, stabilizers, and medium for CdS tetrahedral homologues
Article Abstract:
A large anomalous dipole moment is reported for nanocrystals with a cubic crystal lattice. The molecular modeling approach presented is suitable for detailed theoretical studies of the dipole moments of II-VI and other nanoparticles and interparticle interactions in fluids.
