biocl microflowers were synthesized using bismuth nitrate pentahydrate and sodium chloride by microwave (mw) assisted synthesis method for 23 minutes at 180 w. scanning electron microscopy (sem) studies revealed a unique morphology of flower-like assemblies comprised of nanosheets. the x-ray diffraction (xrd) pattern showed that a highly pure and crystalline phase has been obtained. the energy ...

the zinc-cadmium oxide (zno-cdo) nanocomposites with different weight percentages of cadmium oxide (cdo) nanoparticles were successfully synthesized by the sonochemical method using zinc and cadmium nitrates as precursors to probe their nano-structured surfaces for the decomposition reactions of chloroethyl phenyl sulfide (ceps) as a surrogate of sulfur mustard agent simulant. scanning electron...

sulfated titania nanoparticles (so42-/tio2 nps) were synthesized using titanium tetraisopropoxide (ttip) by the sol-gel method. the structure and morphology of the prepared nanocatalyst was characterized using x-ray diffraction (xrd), scanning electron microscopy (sem) and brunauer–emmett–teller (bet) methods as well as fourier transform infrared (ft-ir) and energy dispersive x-ray (edx) spectr...

In this study the effect of crystallite size reduction and microstructure on the electrochemical corrosion behavior of nanocrystalline nickel (NC Ni) were investigated using Tafel polarization and electrochemical impedance spectroscopy (EIS) measurements in 10 wt.% NaOH. NC Ni coatings were produced by direct current electrodeposition using chloride baths in presence and absence of saccharin as...

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), ...

polyvinylpyrrolidone  /  nickel  oxide  (pvp/nio)  dielectrics  were fabricated  with  sol-gel  method  using  0.2  g  of  pvp  at  different working  temperatures  of  80,  150  and  200  ºc.  structural  properties and surface morphology of the hybrid films were investigated by x-ray  diffraction  (xrd)  and  scanning  electron microscope  (sem) respectively. energy dispersive x-ray spectrosc...

This contribution reports an ecological benevolent route for the fabrication of copper oxide nanoparticles (CuONPs) using Leucaena leucocephala L. leaves extracts at room temperature. Phytochemical screening of the fresh aqueous leaves extract showed the presence of tannins, saponins, coumarins, flavonoids, cardial glycosides, steroids, phenols, carbohydrates and amino acids. Copper oxide parti...

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 single-step approach for the synthesis of multi-walled nanotubes (MWNT) filled with nanowires of Ni/ternary Zr based hydrogen storage alloy has been illustrated. We also demonstrate the generation of COfree hydrogen by methane decomposition over alloy hydride catalyst. The present work also highlights the formation of single-walled nanotubes (SWNT) and MWNTs at varying process conditions. The...

in this paper, we report on the synthesis of cu nanoparticles through a single-precursor route by controlling the growth temperature. selective adsorption of oleylamine on various crystal planes may play an important role in the growth process. the understanding of this self-assembling process will help us develop reliable and reproducible methods to synthesis other three dimensional nanostruct...
