In our previous papers we examined the influence of irradiation on the structure, morphology,
crystallinity, thermal and mechanical properties, and parameters important for "in vitro" and "in
vivo" conditions, as well as for the clinical use of this biomaterial [13].

In atmospheric chemistry and atmospheric physics, CE is a term that characterizes an entire sampling and sample pretreatment procedure, usually represented as a percentage of the original amount of the analyte left for measurement (signal formation) after having passed through the procedure [1].

Structure of the system
The facial recognition process begins with the input of three images of the subject into the system: one image taken from the front, one from the side, and the last one from an arbitrary angle.

Initial structure of fibers is conducted in XRD-patterns (Fig. 2).
The fiber structure was non-crystalline, like amorphous fibers.
Order structure developed gradually above 600 oC.
Evidence of turbostratic structure might be in the whole crystalline structure of carbon fiber which is carbonized at 1200 oC (see XRD-patterns in Fig.7).
Subsequently, order structure developed gradually above 600 oC and finally, crystalline structure of carbon fibers has been carbon turbostratic at 1200 oC.

The article considers the influence of early-age compression on the structure of high-aluminate cement which has been studied using X-ray phase analysis.
In the control sample, the crystal structure has been transformed to more stable cubical hydroaluminates C3AH6 (2Θ=66.72°; 69.96°).
These phases are more active under compression, which is illustrated by X-ray phase analysis of sample subjected to compression at an earlier age (Fig. 1, 3). 3) The load application affects the recrystallization of the hexagonal structure into a cubic structure.

The composition and different molecular structure of crude oils consist predominantly of high concentration of heteroatoms hydrocarbons and vary with their origin.
It is obvious that change of coke structure have been taken place in the time of steam.
Hauser[16] and Marafi[15] reported their studies on initial coke deposition by solid state 13C-NMR and set forth the fine structure of coke at full length drawing a elucidation of coke structure in the time of steam.
The fine structure of coke is demonstrated by Solid state 13C-NMR to a certain degree.

Most of the memristor was fabricated consisting of multilayer structures in nanoscale, in comparison to which the bulk devices are compatible with the state-of-art passive electronics technology and cost effective.
In this work, a bulk memristor fabricated by a sandwiched structure of Ag/Ag2S/Ag cell was reported.
Ag/Ag2S/Ag sandwiched structure was formed by separately compressing of 0.1 g silver powders onto the top and bottom surface of the Ag2S sample.
The patterns shown in the spectra indicate the phase-pure monoclinic structure of Ag2S.
