The inhibitive effect of the extract of Salvia Judica on aluminum corrosion in 1 M NaOH solutions was investigated by using the weight loss method at different temperatures. It was found that the extract play as corrosion inhibitor for aluminum corrosion in 1 M NaOH solution. The inhibition action of the extract was d…
Abstract: Thermodynamics of Cobalt (Co) exchange using a kinetics approach was investigated in alluvial soil samples from two surface soil samples (0-30 cm) of Egyptian soils selected from Nile Delta mainly varied in clay content and other related properties. Kinetics of adsorption and desorption were determined at te…
bstract A In this work, a series of novel 1-(2-(4-xphenyl)-5-(phenylamino)-1,3,4oxadiazole-3(2H)yl) ethanone (X=H,OH,Cl,NO2,N(CH3) (4a-e) were prepared from the condensation of Schiff base (3a-e) with acetic acid. The azomethines were prepared from the corresponding 4phenyl semi carbazide(1) with aryl aldehydes (2a-e)…
This work was to evaluate the efficacies of the nanoparticles (NPs) of silver (Ag) and Gold (Au) against the major tropical mosquitoes. In the present study, the Ag and Au NPs were synthesized by using the cell free extract of Fusarium oxysporum f.sp. pisi fungus. The bioreduction of AgNPs and AuNPs was monitored by u…
Freshly harvested tomato fruit (Solanum lycopersicum) were pre-treated with 0, 50, and 100 µM prohexadione-calcium (Pro-Ca) and then stored at 1 °C for 21 days to investigate the effect of Pro-Ca treatment on electrolyte leakage (EL), malondialdehyde (MDA), proline and total phenols contents, and activity of phenylala…

The paper outlines how experiments were carried out to determine the optimum chromium/carbon (Cr/C) ratio that brings the required hardness of 65HRC an d to establish a quenching technique for the grindi ng balls. Matlab was also used to develop a mathematical model for the ball wear rate and its cost effectiveness ba…
Fabric properties such as pilling and abrasion resistance and tensile strength vary when greige fabric is processed further. The quality of dyed fabric depends on the quality of greige fabric. Cotton Plain and Twill weave fabrics were woven at three different warp yarn tension and then dyed using monochlorotriazine, D…
Necuron is a polyurethane material (PUR) that is used for various applications of industry. The use of these materials in industry increased in recent years because of their good mechanical and machinability properties. Good knowledge of the mechanical behaviour of these materials is highly important therefore this wo…
Present paper studies the possibility to obtain polymer-clay nanocomposites using poly(3methacrylamidopropyl (N,N-dimethyl) dodecyl ammonium bromide) and several commercial clays- Cloisite Na, Cloisite 30B, Cloisite 93A, Cloisite 20A, Cloisite 15A in three different solvents (ethanol, chloroform and propyleneglycol mo…
pressure. The deposited thin films were annealed at 150 ° C in tube furnace in the presence of argon gas. For characterization, thin films were subjected to X-ray diffraction (XRD), SEM, EDS and J.A. Woollam variable angle ellipsometry (VASE) for structural, surface morphological, elemental composition and optical pro…
Abstract-- The effect of carboxylic acid from Palm kernel oil (PKO) on carbon steel SAE 1045 in 1M hydrochloric acid (HCL) media by using weight loss technique for corrosion prevention. The inhibition efficiency of PKO was calculated using weight loss technique. Weight loss and corrosion rates of carbon steel decrease…
Candesartan is an angiotensin-receptor blocker (ARB) with very low bioavailability approximately 15% that can be improved by increasing its solubility and dissolution rate. The aim of this study is to enhance dissolution of candesartan as a model hydrophobic drug through application of liquisolid technology. It was fo…
Summary: Ag NPs were synthesized by the chemical reduction method and were optically characterized. The change in size of the nanoparticles and position of surface Plasmon resonance was studied as a function of concentration of different reactants by using UV-Visible spectroscopy. Red shift was observed in the positio…
Hydroethanolic extracts of leaves of Solanum scabrum and seeds of Cola verticillata were analysed for anticancer properties. A MTT assay was done to evaluate their antiproliferative properties after 24 and 48 h treatment with varying concentrations. qRT-PCR was used to evaluate the modulation of seven genes involved i…
Carbon with nanostructure, is a material that currently being developed in recent years. It is one of the unique materials, showing excellent and unique physical and chemical properties, including high electrical and thermal conductivities, high surface area, high mechanical strength, and chemically inert. Its interes…
In this paper, the nanocrystalline porous silicon (PS) is prepared by electrochemical etching of p-type silicon wafer at currents density 20 mA/cm 2 and with different etching times on the formation nano-sized pore array with a dimension of around few hundreds nanometric. The films were characterized by the measuremen…
Thin films of SnO2: Pd have been deposited on glass substrate at 450 0 C using an alcoholic precursor solution consisting of Tin (IV) Chloride (SnCl4.5H2O) and Palladium Chloride (PdCl2). The influence of increasing Pd concentration on the electrical and optical properties has been investigated. The minimum resistivit…
domain (3-13) x 10 -3 g/L. The morphology of the micellar aggregates is fundamentally influenced by the polymer chemical structure. If in the case of azobenzene and azo-5-crwon-15-ether groups it is possible to obtain 35-155 nm diameter individual micelles, for the azo-6-crown-18-ether group, only small aggregates wit…
Existing spent nuclear fuel (SF) and high active waste (HAW) management policies and practices worldwide are the result of past presumptions that sufficient reprocessing and/or disposal capacity would be available in the near term. Consequently, in the past many countries have developed specific solutions for differen…
