HgxCd1-xS is a technically important class of material owing to its widespread utility in a variety of optoelectronic devices. The structural characteristics and microscopic features of this important composite material obtained using a liquid phase chemical deposition process have been investigated. A series of HgxCd…
INTRODUCTION The main goal of drug delivery and targeting by microbubble is to improve the efficiency of drug action in the region, where the disease cells are arisen and reducing undesired adverse effects, such as toxicity, in the healthy tissues. For the drug action and/or deposition in the targeted region various e…
). The heat treatment of the nanoparticles at two temperatures (900 °C and 1100 °C) formed porous agglomerated iron-doped alumina nanoparticles. The heat-treated powders were characterized by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Characterization results
For power transformers, the magnitude of the first peak of inrush current is ten times more than the rated load current. The main feature of this current is its high amplitude and second harmonic content. An uncontrolled inrush current may lead to the inadvertent operation of the circuit over-current protection system…

Nickel doped cobalt ferrite magnetic nanoparticles were synthesized in a homogeneous aqueous solution in presence of surfactant by co-precipitation route. the particle size was estimated by the full width half maximum (FWHM) of the strongest X-ray diffraction (XRD) peak. The average particle size varied in the range o…
In recent years, there is a growing interest for the use of natural materials in composite applications, where cellulose materials are reinforced in foam gypsum matrix. A result is environmentally friendly low density building material, which can show high tensile and compressive strength, good heat and sound insulati…
The International Atomic Energy Agency (IAEA) promotes safe and effective management of radioactive waste and has suitable programmes in place to serve the needs of Member States in this area. These programmes cover the development and use of safety standards, planning, technologies and approaches needed for the manag…
The mixed ligand complexes of Co (II), Ni (II), Cu (II) and Zn (II) with Schiff bases N-(2-hydroxy-1- naphthylidene)-4-chloroaniline (L1H) and N-(2-hydroxybenzylidene)-2,3-dimethylaniline (L2H) have been synthesized and characterized. The resulting complexes were characterized by elemental analysis, thermogravimetric…
In the present work Zinc Aluminum Oxide (ZAO) thin films have been deposited on glass substrates by DC reactive magnetron sputtering technique at different sputtering powers of Zn varied from 85 W - 125 W. XRD patterns exhibits ZAO thin films had a diffraction peak corresponding to (0 0 2) preferred orientation with c…
Tungsten based microemitter tips have been prepared with various tip radii ranging from 30 to 100 nm. These tips were manufactured by electrochemical etching of a 0.1 mm diameter high purity (99.95%) tungsten wire at the meniscus of two molar NaOH solutions. Contrary to the standard procedure, the tips' surfaces have…
The work compares the effectiveness of selected methods of graphitizing inoculation applied after the spheroidization in the slender tundish ladle of 1 Mg capacity. The inoculation was carried out according to the three various options. The first one was performed simply by means of the block of inoculant inserted in…
The present work proposes hydrotropy as a type of co-solvency method to increase the solubility of Aceclofenac as the drug candidate due to its poor solubility. Aqueous solutions containing small quantities of several water-soluble excipients giving a concentrated solution, may act as a solvent system for some poorly…

Introduction: A 2D isothermal axisymmetric model of an anodesupported Solid Oxide Fuel Cell (SOFC) has been developed. This model has the advantage of being able to deal with different operating parameters: the results shown here are based on a temperature of 1073 K, a pressure of 1 atm and NiYSZ/YSZ/LSM-YSZ as materi…
Addition of select waxes (Fischer-Tropsch and Fatty Acid Amides) to asphalt is an accepted practice in warm-mix asphalt production. Additionally Fischer-Tropsch, Montan wax and Montan wax blends have been used in Europe for several years as compaction aids for bituminous mixtures. Addition of waxes to binders prompts…
An efficient photogalvanic cell containing mannitol as an electron donar, a dye bismark brown as photosensitizer and Sodium Lauryel Sulphate as Surfactant has been investigated for solar energy and storage. The photopotential, photocurrent and power generated by the photogalvanic cell were 975.0mV, 120.0µA and 77.75 µ…
BiFeO3 (BFO) is an attractive material for multifunctional devices. Besides good ferroelectricity and magnetism, BFO also shows large coupling responses and high photo-catalysis efficiency at room temperature (RT). To study the magnetic and phonon properties in BFO nanostructures, we prepared single-crystalline BFO na…
Photodynamic therapy (PDT) of cancer is a treatment based on the accumulation of a porphyrin-related photosensitize r in tumor cells, and their subsequent destruction based on exposure to light source of specific wave length. Hematoporphyrin derivative has been shown a selective localization in malignant tissues and c…
The aim of the present study was to determine the effect of essential oils on antioxidant and antimicrobial properties of collagen hydrolysate. The essential oils were obtained from Laurus nobilis L.
