Introduction Hydrocylone is widely used in separation and classification due to its simple structure, high separating capacity and efficiency, compactness and without moving parts.
Industrial and Engineering Chemistry Research.

This test allowed us to reveal the effect of change of MAE structure under the action of an external magnetic field.
The general structure of the curves is similar to the magnetization curves of carbonyl iron powder.
This difference can be explained by the vitrification of the polymer matrix as well as structure formation of the magnetic particles.
The similarity of curves 1 and 2 shows, that there no internal structure reorganization in the sample appears.
Dependence of the magnetization of a structured MAE on the temperature.

Several compounds of rare earth manganites with various structures were successfully synthesized by this method and their crystal structures were identified by powder X-ray diffractometry.
Structure analysis of the products was taken by powder X-ray diffraction and Rietveld method using RIETAN PROGRAM [21,22].
From the X-ray diffraction patterns, all the phases were tetragonal with K2NiF4 structure (the space group I4/mmm).

The area of application depends on texture properties of these materials and their surface chemistry [1].
Namely, during this treatment the rate of weight loss diminishes, the structure begins to dilate and leads to the development of porosity.
The peaks at around 1593 cm-1 may be assigned to the presence of quinone structure the C–O stretching [30, 37].

Optimizing structure and molecular docking.
Protein flips at 179 ns and amino acid structure change.
It makes protein structure density weak.
This phenomenon is fit with flipping protein structure.

FTIR was applied to characterize the chemical structure of films.
Crystal structure of glutaraldehyde cross-linked silk sericin films XRD is generally used to study the crystalline structure of materials.
Silk II is the spun silk state which consists of β-sheet silk structure.
The results show that the silk sericin crystalline structure affected by glutaraldehyde.
FTIR was used to confirm the cross-linking structure of glutaraldehyde cross-linked silk sericin films.

The coating structure and hybrid sol properties have been analyzed and discussed.
These network structures make the WO3 thin films changed hard and uniform.
Phase structure.
Structure.
The structures of the hybrid xerogel and SiO2 xerogel are analyzed by infrared spectrometer (Fig.8).

Introduction Crystal growth and their morphogenesis is one of the most complex problems in crystallography, physical chemistry and metal science.
Ion etched structure of nodular graphite. 20 µm The proposed hypothesis claims that spheroidising elements (Mg, Ce etc.) associate with the surface active elements in the melt and neutralize them.
a - outgrowth of graphite on the plate face, b - outgrowth of graphite on the basis face plate 15 µm 20 µm Dislocation structure of growing graphite is by one-two order well dispersed than that of ion etched structures under magnification up to 10-50 thousand (Fig. 3).
Ion etched structure of growing graphite. a - concentric structure; b - chevron structure.
Inner structure of ion etched fragments. a - nodular and b - vermicular graphite.

Pore structure characteristics play an important role in transport properties that are closely linked to durability especially for reinforced concrete structure.
Fly ash plays double role in formation of pore structure.
During this process the hydration products of fly ash fill the already existing pore structure.
First observed peak corresponds to the minimum throat dimension (e.g. which is the maximal capillar diameter in whole structure) of an interconnected capillary network between 0,1 – 1 µm.
· Throat size of pore structure decreased with increasing amount of cement in paste.
