Nickel oxide nanostructures with different lengths have been easily synthesized by calcining nickel foil after soaking in LiOH solution of different concentrations. The measurements of electrochemical properties of these NiO nanostructures show that different lengths of NiO nanostructures would have different electrochemical properties and the NiO nanowires with the longest length have the larg...

Background: The incorporation of thallium-201 into 8-hydroxyquinoline was targeted for cell labeling due to interesting physical properties and wide availability of this nuclide as a single photon emission computed tomography (SPECT) radionuclide. Materials and Methods: Thallium-201 (T1/2=3.04 d) in Tl+ form was converted to Tl3+ cation in presence of O3/6M HCl and di-isopropyl ether, controlle...

A variety of hierarchical oxide nanostructures, including ZnO nanonails on nanowires/nanobelts, ZnO nanorods on nanobelts, comb-like ZnO nanostructures, hierarchical MgO nanowires, etc., have been synthesized by thermal vapor evaporation and condensation. Observation of these nanostructures demonstrates the diversity of the geometry of these oxides in the nanoscale range. These nanostructures m...

two cu(ii) complexes, [cu(l1)2](no3)2 (1) and [cu(l2)2] (no3)2(2), which l1 and l2 schiff base ligands are 2-(thiophene-2-yl) -1h-imidazo [4,5-f] [1,10] phenanthroline and 2-(furane-2-yl)-1h-imidazo[4,5-f] [1,10] phenenthroline, respectively, were synthesized and characterized by physico - chemical and spectroscopic methods. corresponded cuo nanoparticles were prepared by calcination of the obt...

Thallium (Tl) is one of the most toxic heavy metals affecting both humans and animals, yet least studied for its toxicological effects. A total 40 male Wistar rats were randomly divided into four Groups with 10 in each Group. Group I received distilled water only served as a control. II, III, IV thallium sulfate (I) at 0.48, 0.93, 1.33 mg/kg body weight, respectively, drinking 90 days. In rats,...

Photoluminescence measurements showed that needle-like tungsten oxide nanostructures synthesized at 590°C to 750°C by the thermal evaporation of WO3 nanopowders without the use of a catalyst had an intense near-ultraviolet (NUV) emission band that was different from that of the tungsten oxide nanostructures obtained in other temperature ranges. The intense NUV emission might be due to the local...

By spark-eroding Fe75Si15B10 in water/ethanol mixtures, spherical particles with nanostructured cores consisting of mixed amorphous and crystalline phases were produced. The relative volume fractions of the amorphous and crystalline phases were dependent on the water/ethanol ratio. In the same process, continuous oxide layers were formed on the particle surfaces. The basic mechanisms responsibl...

In this report we review the growth of indium oxide (In2O3) nanostructures, including octahedral nanocrystals (NCs), nanobelts (NBs), nanosheets (NSs), and nanowires (NWs), by hot-wall chemical vapor deposition (HW-CVD). This system is highly controllable, allowing the user to easily access different growth regimes – each corresponding to the growth of a different nanostructure – by changing gr...
