The aim of this work is to compare the results concerning the shape of crystalline grain and structure of the SiO2CuOх and SiO2CuOXSnOy thin films in depending on the Cu and Sn amount in the precursor solution.
The SEM micrographs confirms the porous structure of SiO2CuOx film (Fig.1a).
The agglomerates have spherical shape flower-like structure with diameter in the range of 0.7-1 μm composed of many interconnected copper oxides crystallites with the size of 30-50 nm (Fig.1b).
In addition, spectra SiO2CuOx and SiO2CuOxSnOy contain two structures (B, D) lying above them in energy peaks.

The luminescence properties of rare-earth doped Gd4Si2O7N2 with cuspidine structure were examined.
In this study, we selected Gd4Si2O7N2 with cuspidine structure as a host material (and Ce3+ and Tb3+ as activators), and examined the changes of luminescence properties, due to the doping of these activators.

The Deviation Coefficient of Crystalline Nanoceramics Structure from Thermodynamically Equilibrium State O.L.
Introduction Nanoparticles have metastable crystalline structure.
Then the difference of experimental values of ∆dACS and coefficient k from Eq. 2 (k - ∆dACS ) reflects a deviation degree of investigated structure from thermodynamically equilibrium state.
The higher microhardness was observed in ceramics samples for which the modulus of the specified difference | k -∆dACS | is minimal, i.e. in samples, which structure is more close to an equilibrium state.

In the glassy state, the SiO4 tetrahedra form a disordered structures and clusters of voids [6,7].
The states of crystalline and silica glass structures differ from each other by the internal energy, although mobility of the structure elements (and the atoms that constitute them) are identical at room temperatures.
This O-atom, additional to the regular structure, is defined hereafter as a defect.
This force is added to the interaction potential of He-atom in a structure, but the short order in disordered structure is preserved as a regular structure.

Moreover, the structure and morphology of PBO/MWCNT nanocomposites have been investigated in this study.
Diffraction peaks for MWCNTs are not detectable in spectra and all the diffraction peaks can be assigned to the ordered structure of PBO in PBO/MWCNT nanocomposites.
This indicates that the ordered structure of PBO matrix largely remains after introducing MWCNT, consistent with earlier reports for PBO/CNT composites [10].
The structure and morphology of the obtained PBO/MWCNT composites have been investigated.
