A. Soltanmoradi I. Mobasherpour M. R. Rahimipour S. Manafi,

In the present work, we report a suitable approach for the preparation of BaTiO3 nanostructures via the hydrothermal condition using Dolapix ET85 as surfactant. The powders were investigated by X-ray diffraction (XRD), scanning election microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAX), field emission transmission electron microscopy (FETEM), selected area electron diffra...

introduction: the aim of this in vitro study was to evaluate the setting time, flow, film thickness, solubility, radiopacity and characterization analysis of three epoxy resin based sealers including two experimental sealers and ah-26. methods and materials: five samples of each material were evaluated for setting time, flow, film thickness, solubility and radiopacity according to iso 6876 stan...

< p>Mg-Fe bi-metal oxide was prepared and utilized as a magnetized renewable solid base catalyst for formation of 2-aminothiophenes by means of Gewald’s reaction. The prepared heterogeneous basic solid catalyst can be separated by a magnet and reused without considerable wastage in this activity. The structure of the aforementioned magnetized basic nano-catalyst was studied by XRD (X-ray diffra...

in this research na-y was synthesized by hydrothermal method and used as support for preparation of sn/pt/na-y catalysts using two different tin precursors, bu3sn(cl) and sncl2.2h2o, by sequential impregnation, in which the pt  was deposited first and in the next step sn was deposited. the catalysts were characterized by h2 chemisorption, transmission electron microscopy (tem), scanning electro...

D. Ghanbari M. Ranjbar M. Salavati-Niasari,

ZnS  nanoparticles  were  synthesized  via  a  simple  surfactant  free microwave  route.  In  this  synthesis, thioacetamide  was  used  as sulfur  source.  The effects  of different  parameters  such  as  type of zinc precursor,  time  and  power  of  irradiation  on  the  morphology and  particle  size  of  the  products  have been  investigated.  The nanostructures  were  characterized  by ...
