Doping of Nano Zinc  Ferrites by Chromium: Structural and Magnetic Properties Studies
A SERIES OF CHROMIUM-SUBSTITUTED ZINC FERRITES (CRXZN FE2-XO4 WITH = 0.00, 0.10, 0.20, 0.30, 0.40) WERE SYNTHESIZED VIA HYDROTHERMAL METHOD. THE STRUCTURAL CHARACTERIZATIONS OF ALL THE PREPARED SAMPLES WERE DONE USING XRD, FTIR AND EDAX, TEM, HR-TEM AND TGA MEASUREMENTS . THESE STUDIES CONFIRMED THE FORMATION OF SINGLE-PHASE INVERSE SPINEL STRUCTURE IN ALL THE COMPOSITIONS. FROM HR-TEM MEASURMENTS, CRYSTALLINITY ARE ... إقراء المزيد

Carbon steel pipelines corrosion inhibition by some novel imines during acidizing treatment of oil wells: Electrochemical and quantum chemical studies
The corrosion protection of the equipments and vessels is one of chief concerns of the maintenance and design engineers. From this point of view, three novel imine compounds were prepared and their structures were characterized by X-ray, 13C-NMR, 1H-NMR, mass, UV-Vis, FT-IR, spectral data and elemental analyses. The corrosion inhibition of the investigated inhibitors towards carbon steel in 15% HCl ... إقراء المزيد

Synthesis, photoluminescence and optical constants evaluations of ultralong CdO nanowires prepared by vapor transport method
Ultralong CdO nanowires (NWs) were synthesized on Au coated Si and quartz substrates by using vapor transport method. The synthesis temperature was chosen via thermal gravimetry analysis (TGA) and it was 1150C. The formation of CdO was confirmed by energy dispersive analysis of X-ray (EDAX) and Fourier transform infrared (FT-IR) spectroscopy analysis. The CdO nanowires was found to grow via ... إقراء المزيد

Palate of Turkey (Meleagris gallopavo): Gross Anatomical, Light and Scanning Electron Microscopical Study
This investigation aimed to determine the morphological characteristics of the palate of bronze black turkey by gross anatomy, light and scanning electron microscopy. The oral roof (palate) constitutes 87.73% of the oropharyngeal roof length, comprising two parts; rostral and caudal. The rostral part is characterized by the presence of median palatine ridge, rostral and caudal lateral palatine ridges, narrow part ... إقراء المزيد

Morphological Studies on the Upper Beak of Turkey (Meleagris gallopavo)
This study was carried out to provide a detailed description about the upper beak of turkey, regarding its gross anatomical, light and scanning electron microscopic morphology. The upper beak extends in a hook like infront of the lower beak. It measures 53.80 mm long. The height and width of the upper beak increase caudalwards. SEM shows that the tip and ... إقراء المزيد

Gross Anatomical, Light and Scanning Electron Microscopic Studies on the Pharyngeal Roof of Turkey (Meleagris gallopavo): Comparative Study
pharyngeal roof using light and scanning electron microscopy. Studied parts from the roof of the turkey's pharynx were processed and stained by convential stains to illustrate the mucosa, salivary glands, and connective tissue infiltration. Also, Scanning electron investigations were applied on pharyngeal papillae and pharyngeoseophageal junction. Grossly, the pharyngeal roof was shown to constitute about 12.27% of the oropharyngeal roof ... إقراء المزيد

Macro and Microanatomical Studies on the Choanal Slit of Turkey (Meleagris gallopavo)
This work was carried out to describe the morphological characteristics of the choanal slit of the turkey through gross, light, and scanning electron microscopy. The choanal slit measures 27.62 mm long, and constitutes 38.30 % of the total length of the palate. The edges of the narrow part of the choanal slit is smooth rostrally but slightly thickened caudally due ... إقراء المزيد

Removal of Cd(II) ions From Aqueous Solution using Nano sized Moringa Oleifera
This research aims to study the effect of nano sized _Moringa oleifera_ on adsorption of Cd2+ ions from aqueous solution. The investigated biosorbent was characterized by FTIR, SEM, TEM, XRD and EDS techniques. The influence of pH, temperature, adsorbent dosage, contact time, metal ion concentration and chemical treatment of biomass were investigated. The maximum capacity (qm) of Cd2+ ions biosorption ... إقراء المزيد

One step syntheses of S incorporated ZnO nanowires for photocatalysis applications
S incorporated ZnO nanowires (NWs) were prepared by vapor transport method using ZnS bulk precursor. Effects of S incorporation on the structural, morphological, optical as well as photocatalysis performance of ZnO NWs were studied. EDAX analysis revealed existence of S with low ratio. A deformation of the hexagonal nanowires was observed inasmuch to the S existence. X-ray diffraction analysis asserted ... إقراء المزيد
