nanocrystals of zno were prepared by microwave irradiation using zn (ii) acetate and triethanol amin (tea) as the starting materials and water as solvent. the nanocrystals of zno with hexagonal (wurtzite) structure were characterized by x-ray powder diffraction (xrd), transmission electron microscopy (tem), scanning electron microscopy (sem), uv-vis absorption and ftir spectroscopy techniques.

bismuth sulfide nano-rods and nano-flowers were synthesized via a hydrothermal reaction at a relatively low temperature. thioglycolic acid is used as sulfur source and capping agent simultaneously. bi2s3 nanostructures were then added to acrylonitrile-butadiene-styrene (abs) copolymer. the thermal stability behavior of abs filled with bismuth sulfide nano-rods were investigated by thermogravime...

an anionic fe(ii) complex, (bmim)4[fe(cn)6] (where bmim is 1-butyl-3-methylimidazolium), was synthesized in ionic liquid [bmim][pf6] under reflux condition. the complex was characterized by elemental analysis and spectroscopic methods. the magnetite (fe3o4) nanoparticles were prepared by the hydrothermal and solvothermal (in ionic liquid [bmim][pf6]) methods from (bmim)4[fe(cn)6] as a precursor...

We report an ecofriendly novel method for copper nanoparticles (CuNPs) synthesis by hydrothermal processes using an activated carboxymethyl gum of locally available medicinal plant Cochlospermum gossypiumas capping agent. The synthesized CuNPs characterized by Ultraviolet - visible Spectroscopy (UV-Vis), Fourier – transform infrared Spectroscopy (FTIR), and Transmission Electron Micros...

Two new nano particles of copper (II) and nickel (II) complexes, [Cu(cd5Clsalen)] (1) and [Ni(cd5Clsalen)] (2) with unsymmetrical tetradentate Schiff base ligand cd5Clsalen={methyl-2-[N-[2-(2-hydroxy-5-choloro-2phenyl) methylidynetrilo]ethyl}amino-1-cyclopentenedithiocarboxylate, were synthesized by hydrothermal method. These compounds were characterized by a variety of physic-chemical techniqu...

Maghemite and magnetite nanoparticles and nanorode are now losing interests in the field of nanobiotechnology and pharmaceutical for their applications. This paper reports on a hydrothermal process for the synthesis of Fe2 O3 in the γ-phases nanorodes, when the hydrothermal temperature was 100 ̊ C. The uniqueness of the method lies in the use of ferrous ammonium sulphate, hexamine was added as t...

Hydrothermal formation reaction of tobermorite in the autoclaved aerated concrete (AAC) process has been investigated by in-situ X-ray diffraction. High-energy X-rays from a synchrotron radiation source in combination with a newly developed autoclave cell and a photon-counting pixel array detector were used. XRD measurements were conducted in a temperature range of 100–190 °C throughout 12 h of...

clay minerals are considered the most important components of clastic reservoir rock evaluation studies. the shurijeh gas reservoir formation, represented by shaly sandstones of the late jurassic-early cretaceous age, is the main reservoir rock in the eastern kopet-dagh sedimentary basin, ne iran. in this study, x-ray diffraction (xrd), x-ray fluorescence (xrf), scanning electron microscopic (s...
