This work deals with the planning and fabrication of a functionally gradient coppernickel composition via Laser Metal Deposition (LMD). Various compositions of copper and nickel were made by blending different weight percentages which were then sequentially deposited to fabricate functionally gradient copper-nickel thin-wall structures. Analyses were performed by sectioning the thin-wall sample...
According to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of Cu, Ag, Au, Pb and Se. In this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. Silver was separated from anode slime by using of HNO3 and HCl. X-Ray fluorescence spectroscopy (XRF) was used to characterize anode sl...
A novel and cost-effective catalyst for synthesis of 2,3'-dihydroquinazolin-4-(1H)-ones was developed utilizing a combined nanocomposite obtained from bonding TiCl3 to hydroxyl groups of nanofibrillated cellulose as a green and inexpensive support.The structure of the catalyst was investigated using the Fourier transform infrared spectroscopy (FT-IR), field emission scanning...
A rapid and efficient method for the synthesis of bis-thiazolidinones has been achieved by pseudo five-component reaction of aldehydes, ethylenediamine and thioglycolic acid in the presence of nano-NiZr4(PO4)6 as catalyst under microwave irradiation. Nano-NiZr4(PO4)6 has been characterized by powder X-ray diffraction, scanning electronic microscopy (SEM), energy dispersive spectroscopy (EDS), v...
Superparamagnetic few-layer graphene nanocomposites (FLG- NCs) can be used for many technological applications, such as solar cells, batteries, touch panels and supercapacitors. In this work, we applied electrochemical exfoliation method as a simple, one step and economical technique to fabricate FLG- NCs. The fabricated Superparamagnetic FLG- NCs were characterized by X-ray diffraction (XRD), ...
in this research, b4c-ni cermet coating was sprayed on the surface of 4130 steel from b4c and ni feed-stockpowders using high velocity oxy-fuel (hvof) method. in order to characterize the tribological behavior of thecoating, ball on disk wear tests were done at the ambient temperature and under the loads of 1, 3 and 5 n.phase analysis of the coating after spraying was studied by x-ray diffracto...
germanium nanowires (genws) were synthesized using chemical vapor deposition (cvd) based on vapor–liquid–solid (vls) mechanism with au nanoparticles as catalyst and germanium tetrachloride (gecl4) as a precursor of germanium. au catalysts were deposited on silicon wafer as a thin film, firstly by sputtering technique and secondly by submerging the silicon substrates in au colloidal solution, wh...
in this paper, preparation, bioactivity, and osteoblast cell behavior of cortical bone derived nanobiphasic calcium phosphate (nano-bcp) are presented. the calcined bovine bone samples with the addition of di-ammonium hydrogen phosphate were heated at 700°c for 100 min, and thus nano-bcp with the composition of 63/37 hydroxyapatite (ha)/β-tricalcium phosphate (β-tcp) was produced. scanning elec...

In recent years, green synthesis of nanoparticles has attracted a great attention because of medicine and biological applications. In this work, bismuth oxide nanoparticles (Bi2O3 NP) was prepared via green synthesis using mentha pulegium aqueous extract after 24 h at 90°C. The product was characterized by ultraviolet-visible (UV-VIS) spectrophotometer, Fourier transform infrared (FTIR), X-ray ...
