We present a low-temperature inverse micelle solvothermal approach for the synthesis of germanium nanocubes using the surfactant heptaethylene glycol monododecyl ether as a capping agent. X-ray diffraction results indicate that the as-prepared nanocubes are diamond-type pure germanium. Transmission electron microscopy observations show that the as-prepared germanium nanocubes have an edge lengt...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...

Using Fe(NO3)3.9H2O, Co(NO3)2.6H2O and Mn(NO3)2.4H2O the magnetic properties of nanoparticles trimetalic Iron - Cobalt - Manganese, with supported Magnesium oxide have been prepared by Co-precipitation and Solvothermal methods. The prepared samples are characterized by Scanning Electron Micros...
Fuel cells, secondary batteries and capacitors are among many promising energy storage devices. In particular, supercapacitors have attracted much attention because of their long life cycle and high power density. Graphene/nickel ferrite(G-NF) based supercapacitors were successfully fabricated through a one-step facile solvothermal route. Effects of synthesis conditions i.e. solvothermal time a...
Metal organic frameworks (MOFs) of copper and zinc synthesized with 1,4benzenedicarboxylic acid and N,N-dimethylformamide at room temperature and by solvothermal method is reported in this paper. The MOFs were characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), High resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD) and...
I report a facile wet-chemical method for the synthesis of one-dimensional copper hydroxide nitrate nanostructures in 2-propanol under solvothermal conditions. Single-crystalline nearly monodispersed copper hydroxide nitrate nanorods and nanobelts with selected breadths in the range of 100 nm to 1 μm have been successfully prepared by a solvothermal method through controlling the experimental p...

Nitrogen doping in combination with the brookite phase or a mixture of TiO2 polymorphs nanomaterials can enhance photocatalytic activity under visible light. Generally, nitrogendopedanatase/brookite mixed phases TiO2 nanoparticles obtained by hydrothermal or solvothermal method need to be at high temperature and with long time heating treatment. Furthermore, the surface areas of them are low (<...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
