Published: April 2023

superconductor samples with chemical composition (Hg1-xPbxBa2Ca3-yMgyCu O10+δ) were prepared by solid state reaction method. The effect of partial substitution of Pb and Mg on the structural and electrical properties of this compound were studied. The lattice parameters were characterized by using X-ray diffraction technique and the results showed that all the samples crystallize in tetragonal crystal structure. This technique proved increase in value of lattice constant (c) with increasing in Pb concentration until 0.4 when y= 0 and decreased after this concentration. On the other hand the partial substitution of Mg in Ca showed decreasing in the value of (c) with increasing Mg concentration to (0.2,0.4,0.8,1,1.4,1.6) when the Pb is constant at (0.4), but the value of (c) increased with increasing Mg to (0.6,1.2). Standard four-probe method used in electrical resistivity measurements and the measurements showed an improvement in Tc from (0.1-0.4) and after this concentration Tc value decreased at substitution of Pb in Hg when Mg=0, where the critical temperature increases from 121K to 134K with an increase of x from 0 to 0.4 and decreases after this concentration to 120K , but for substitution of Mg in Ca the Tc is increased to 135K,136K,139K,142K and 145K with increasing of Mg to (0.2,0.4,0.8,1,1.4) and decreased to 134K,140K and 140K with increasing concentration of Mg to (0.6,1.2,1.6) while Pb is constant at (0.4). The surface has been investigated by using scanning electron microscope (SEM) and atomic force microscopy (AFM). These tests were shown that all specimens which tested have good crystalline and homogeneous surface .

Published: April 2023

In this study,the nanoparticles of zinc oxide were readily prepared through Hydrothermal process by using zinc nitrate hexahydrate, and Sodium hydroxide as aprecursors. The surface topology, and crystalline structure of prepared ZnO nanoparticles were studied. X-ray diffraction (XRD) revealed that the prepared ZnO nano particles is highly crystalline, having (wurtzite) crystal structure. The optical analysis by UV–vis showed that these ZnO nano particles have considerable blue shift in the optical band gap energy (Eg = 4.9eV), and this may be to the quantum confinement effect of nano particles. The FT-IR results shows the existence of OH, COO, H2O groups the characteristic vibrational modes of Zn–O were identified. and AFM analysis showed that the diameters of the ZnO particles is in ananometer range of (70-74)nm

In This research we study the effect of photo chemical etching and electrochemical etching on topography of porous silicon surfaces, the results showed that photo chemical etching produced roughness silicon layer which can have thickness be less of porous silicon layer which is produced by electro chemical etching When all the wafers have same etching time and hydrofluoric solution (HF) concentration, the wafers have same resistance (10 Ω.cm).
Also the results showed the roughness of porous silicon layers produced by electro chemical method which is bigger than the roughness of porous silicon layers produced by photo chemical method and the results of roughness of porous silicon layers, Pore diameter and porous layer thickness were produced by electro chemical method (1.55(µm) ((0.99(µm)) and ((1.21(µm) respectively), the results of roughness of porous silicon layers, Pore diameter and porous layer thickness were produced by photo chemical method 0.63)) nm -1.55)) (µm) ),so the (84.9 (nm)- and (3.94(nm) respectively .

Published: April 2023

Four sites with different depth in AL-Fursan area/ North Tikrit city were selected for recent deposits sampling. The geotechnical properties of soil were tested and improvement of engineering properties of soil by cement was carried out. The geotechnical properties test results revealed that the moisture content ranges between (0.53 -1.45)% which is low because of sampling in summer season, while the grain size analysis show that the soil at the study area is coarse soil (sand) with fines. The soil type in the first site is clayey sand (SC), the second site contains sand with equal percentage of silt and clay (SC- SM) , the third and fourth site types are silty sand (SM). The specific gravity ranges between (2.46- 2.72) sites (1,2,3) are low liquid limit and low swelling index but the fourth site is moderate. The value of cohesion strength for the four sites are (16, 13, 1, 8)kPa respectively, sites (1) and (2) are moderate cohesion while sites (3) and (4) are non-cohesion, none plastic and un active.
The low values of cohesion strength belongs to high percentage of coarse particles in the area. The values of internal friction angles ranges between (300- 370). The consolidation test results revealed that all sites were moderate compressive index except the first site which is low compressive and low swelling. The study area soil are neutral and high content of gypsum and soluble Dissolved salts and also high organic content. The soil improvement by cement tests results show increasing of cohesion and internal friction angle and the compaction test results show the samples are well sorted.
