Density functional theory (DFT) calculations were performed to investigate the effects of a carbon nanotube (CNT) on the properties of the fluorouracil (F-Uracil) anticancer drug. To achieve the purpose, a molecular model including both of F-Uracil and CNT molecules was created to represent the CNT@F-Uracil compound. The optimized parameters indicated that the new compound could […]
An in vitro study was conducted to know the veridical properties of silver nanoparticles synthesized from locally available white button mushrooms (Agaricus bisporus). The characterized colloidal silver nanoparticles exhibited as an excellent virucidal property on viral strain Bacteriophage. The viral inactivation process was increased with increasing the concentration of colloidal silver nanoparticles. The silver nanoparticle […]
The composite powders of barium-magnesium ferrite were prepared using sol-gel auto-combustion and microwave methods. The crystal structure and the shape of nanocomposites have been compared. X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Vibrating Sample Magnetometer (VSM) were used to investigate the structural, morphological and magnetic properties of nanopowder. The formation of pure crystallized nanocomposites […]
Nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a Ba:Fe molar ratio of 1:10. The effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. The results revealed that the formation of barium […]
Recovery Factor is an important parameter in determining commercial viability of the oil Reservoirs. Wettability is a major factor that affects oil Recovery. Therefore, changing rock wettability may enhance oil recovery. In this paper, the effect of polysilicon nanoparticles on wettability change of Iranian carbonate reservoir is investigated. To assess this, hydrophilic changes of carbonate […]
Porous Silicon (PS) layers have been prepared from p-type silicon wafers of (100) orientation. SEM, XRD, FTIR and PL studies were done to characterize the surface morphological and optical properties of PS. The porosity of the PS samples was determined using the parameters obtained from SEM images by geometric method. The refractive index values of […]
This paper reports the correlation between film thickness, nanostructure and DC electrical properties of copper thin films deposited by PVD method on glass substrate. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used for crystallography and morphology investigation, respectively. Resistivity was measured by four point probe instrument, while a Hall effects measurement system was […]
A new mixed halo chromate nanoparticle compound was synthesised and characterized. Triphenylphosphonium trifluoroiodochromate (III)[P(C6H5)3H]+[CrF3I]– nanoparticle was synthesized by using triphenylphosphonium iodide reaction with CrF3, in the presence of 3-mercaptopropionic acid. This method is a simple and direct method. The product was characterized by spectroscopic and analytical methods such as 31P-NMR, FT-IR, XRD, SEM. Theoretical calculations […]
ZrO2 nanopowder was prepared by the sol-gel auto-combustion method. The product was characterized by X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDX) and scanning electron microscopy (SEM). The average crystalline size of ZrO2 was obtained 62 nm. Also, photocatalytic removal of nitrophenol from aqueous solution by using nanoscale ZrO2 under UV light irradiation was […]
For the first time this study reported the success of using nanocrystalline hexagonal close-packed (hcp) nickel (Ni) modified composite graphite (CG) electrode (hcp-nano Ni/CG) for the electrocatalytic oxidation of glycerol in alkaline medium (0.1 M KOH). The hcp-nano Ni/CG electrode had an improve response and specificity on the electrocatalytic oxidation of glycerol over the bare […]
Most reservoir fluids contain heavy paraffinic compounds that may precipitate as a solid or solid like material called wax if the fluid is cooled down. Wax precipitation is a phenomenon of considerable importance in oil industry. An increase in aggregation results in enhanced oil viscosity. This however causes significant negative effects on production, transportation and […]
