The XRD pattern exhibits broad diffraction peaks in the 2q range of 30-45°and DSC curve shows a clear endothermic event associated with glass transition and a sharp exothermic crystallization peak, which confirms the amorphous structure for the 6 mm Mg65Cu18Ni6Gd11 rod.
It was clarified that such atoms constitution could lead to the formation of glassy structure with a higher degree of dense random packed atomic configuration, local atomic configuration different from that of the corresponding crystalline phase and homogeneous atomic configuration of multicomponents on a long-range scale.
With such glassy structure, the alloys could have high liquid/solid interfacial energy, low atomic diffusivity and require long range atomic rearrangements for crystallization to occur, thus favored the formation of bulk glassy alloys.
Interestingly, from an alloy chemistry point of view, the rare earth Gd has nearly identical features with Y.

As a kind of materials used in high temperature thermal structure field, there are two key properties need to be researched.
The liquid precursor from the Institute of Chemistry Chinese Academy of Sciences, Beijing, China, which was evenly infiltrated the fiber preform under the pressure of 0.2~0.4MPa.
Consequently, the RTS is a key factor for the SiC/SiC composite when the SiC/SiC composites were used as high temperature thermal structure materials.

The transport of the chemical substance is influenced by wood structure (e.g. a type and number of conductive cells, their interconnections, luminal cross-section, tyloses, the degree of pits), wood moisture content, application properties of a preservative, compression and diffusion transport forces [7, 8].

Comparative Evaluation of Zinc Coatings on Mild Steel: Microstructure and Corrosion Resistance Fatima Zohra Lemmadi1,a, Ines Hamdi2,b*, Fouad Chabane3,c 1Laboratory of Physics of Thin Films and Applications, University of Biskra, Biskra, Algeria 2Industrial Chemistry Department, University of Biskra, Biskra, Algeria 3Department of Mechanical Engineering, University of Biskra, Biskra, Algeria af.lemmadi@univ-biskra.dz, bines.hamdi@univ-biskra.dz, cf.chabane@univ-biskra.dz Keywords: Mild steel, Zinc coating, Hot-dip galvanization, Electroplating, Corrosion resistance.
Each coating process—whether it is electroplating, TC galvanizing, or hot-dip galvanizing—has resulted in a uniform, coherent structure that significantly differs in appearance from the uncoated mild steel (a).
The color variations in the micrographs can be attributed to the different phases and crystal structures that form during the deposition process, with zinc showing clear signs of a well-established bond between the coating and the steel substrate.
· Electroplated zinc coatings, while uniform and well-adhered, showed lower long-term protection due to their thinner structure

Corrosion is a destructive and cost-bearing phenomenon for every industry dealing with metallic structures.
Multiphase pipelines of oil & gas gathering systems are more vulnerable to corrosion phenomena as a result of complicated water chemistry, presence of acid gasses such as CO2 and H2S, multiphase flow, etc.

Based on the XRD(Fig.6) and EDS results (Table.3), these crystal layers were predominately FeS along with more amorphous structures FeCO3.

Then, the capsule shells in some way (evaporation of the solvent, cooling, the formation of three-dimensional structures, etc.), are transferred to a more solid state, this increases the mechanical strength of the formed microcapsules.
Experimental Part The processes of microencapsulation of aromatic polyetheretherketones and copolyetheretherketones of structures were carried out: I - polyetheretherketone based on diphenylolpropane and 4,4'-difluorobenzophenone; II - copolyetheretherketone based on diphenylolpropane, 4,4'-dioxydiphenyl and 4,4'-difluorobenzophenone; III - polyetheretherketone based on phenolphthalein and 4,4'-difluorobenzophenone; IV - copolyether ether ketone based on phenolphthalein, 4,4'-dioxydiphenyl and 4,4'-difluorobenzophenone; V - copolyetheretherketone based on diphenylolpropane, phenolphthalein and 4,4'-difluorobenzophenone.
Based on the chemical structures of gelatin, polyetheretherketone, and copolyetheretherketone, the localization of gelatin molecules on the surface of polyester particles can be explained by the formation of intermolecular hydrogen bonds (Fig. 7) of the form: Fig. 7.

Structure of the applied IL is presented in Fig. 1.
Cyphos IL 109 structure.
It is positive that the Cyphos IL 109 could be reused several times, however a decrease in percentage extraction indicates possible changes in the extraction mechanism or structure of complexes, so that is needs further investigations.

Mill for SRP Fine Grinding As a result of the analysis of different structures of impact centrifugal mills and previous laboratory tests, a new design of the centrifugal mill (Fig. 1.) was developed and proposed [1].
Strength calculations confirmed the utility of the closed structure of the working body. 1 - four beater elements; 2 - two beater elements Fig. 2.
Dependence of ceramic samples strength on the SRP filler content at burning temperature of 1050°C In case of further increase in burning additive concentration (6, 8, 10% by weight), gradual decrease in strength is observed, which is associated with significant expansion of the ceramic mass structure.
