The experimental SAXS data were normalized for the intensity of the incident beam.
Initial processing of the experimental SAXS data was performed using the PRIMUS software [5].
SAXS data of glass nanocomposites with 1% charged CdS heat treated at 650°C (B) and 2% charged CdS heat treated at 580 °C (C) and 650 °C (D).
SAXS data of CdS NPs in THEOS matrix: SAXS experimental intensity (dots) and scattering intensity from ab abito model (red line).
Results of numerical modeling of spatial model of CdS NPs (Fig. 2 top insert) revealed that CdS nanoparticle are not spherical, but are elongated structures, similar to cylinder or ellipsoid in contrast of spherical nanoparticles obtained by reduction in glass matrix.

The tester included shear plate, plate-push device, and control and data acquisition systems.
The distance and shear force were measured and the dates were recorded by data logger.
Data processing and analysis.
Hence, the shear force was calculated by removing some initial data.
Moreover, travel reduction (slip) and tractive efficiency (TE) can also be obtained based on the traction prediction equation.

These results are in agreement with the data of [23, 24, 27, 46], and they disagree with the authors who indicate much higher dislocation densities (e.g. [26]).
The <110>Nb axis coincides with the drawing direction, in agreement with the above described electron-microscopic data and numerous publications [11, 13, 16, 28, 47, etc.].
However, the Nb grain size distribution in the former seems more uniform and the sizes are somewhat smaller, which is in agreement with the data obtained in [50, 51].
These data are in agreement with refs [8, 9], where it is suggested that this misorientation in the composites of both types is due to the semi-coherent Cu-Nb interfaces.
This suggestion is in agreement with the data by Deng et al. [16], who demonstrated that Nb grains are more curved and distorted at the interfaces than in the bulk.
