A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...

Analyses of experimental data for NQR frequency shifts as a function of temperature reveal a dominant T4 dependence at sufficiently low temperature, T ≲ 20°K, in accord with a recent prediction. The results indicate the ...

When the target is in the solid state, most infrared spectral features are manifestly asymmetric; hence, a line shape function well-grounded in theory is necessary to ascertain the net energy taken by the associated ...

Nanoparticles (NPs) and subnanometer clusters exhibit novel physical andchemical properties that differ significantly from their counterpart bulkmaterials.  This is mainly originatedfrom the large fraction of subordinated ...

The atomic structure determination of solid surfaces by LEED (Low Energy Electron Diffraction) is a problem that requires an extensive search in the parameters space that usually includes structural parameters, the Debye ...

High temperature 57Fe MOsshaner effect measurements in annealed icosahedral A1CuFe alloy are reported. The anomalous decrease in Debye-Waller factor is qualitatively interpretated. It is suggested using consistent ...

A new modified lithium-phosphate glass has been obtained by environmentally friendly components. This glass has provided a remarkable lithium ion solid electrolyte. Frequency-dependent electrical data of several lithium-phosphate ...
