Magnetic data is useful in both hydrocarbon exploration and mining exploration. In hydrocarbon exploration, aeromagnetic data is an effective method for locating strike-slip faulting in magnetic basement. Also, high resolution surveys enhance delineation of both subtle basement features and intrasedimentary sources. In fact, magnetic methods has evolved from its sole use for mapping basement st...

Caffeine loaded magnetic nanoparticle was successfully synthesized and were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), thermo gravimetric analysis (TGA), differential thermal analysis (DTA) and vibrating sample magnetometer (VSM). The resulting nanocom...

Nanocrystalline ZnO particles were prepared by a novel sonochemical route from zinc acetate and sodium hydroxide without any requirement of calcination steps at high temperature and without surfactants. Variations in several parameters and their effects on the structural (crystal size and morphology) properties of nanoparticles were investigated. Characterizations were carried out by X-Ray ...

Silica  coated magnetite  nanoparticles were  covalent  grafted with  3-aminopropyl trimethoxysilane  to give APTSCMNPs. Reaction of  the resulted nanomaterial with 4-formyl benzo-12-crown-4 ether afforded FB12C4/APTSMNPs  nanocomposite  material  in  which  the  crown ether  moiety  was  attached  through  propyl  chain  spacer. Characterization of  the prepared nanocomposite was performed wit...

صخلملا The aim of this study isto examine whether radiofrequency (RF) used in cellular phone communications at a specific absorption rate (SAR) less than 1.2 w/kg could increase the spontaneous rate of sister chromatid exchanges (SCE) or elicit alterations both in the cell replication index (CRI) and mitotic index (MI) in human peripheral blood lymphocytes. Whole blood samples were obtained fro...

a new metal-organic compound, [fe(pydc)(dmso)(h2o)cl], (where pydc is pyridine-2, 6-dicarboxylate and dmso is dimethyl sulfoxide), has been synthesized and characterized by singlecrystal x-ray diffraction, tga/dta, ir and raman spectroscopy. green-yellow crystals,crystallized in the monoclinic system, space group p21/n, a = 7.2461(4) å, b = 10.3018(4) å, c =17.7667(10) å, α = 90°, β = 90.014°(5...
