The microwave assisted synthesis nowadays attracts a great deal of attention. Monoclinic phase VO2 (M) was prepared from NH4VO3 and H2C2O4 · 2H2O by a rapid microwave assisted technique. The synthesis parameters, microwave irradiation time, microwave power, and calcinations temperature were systematically varied and their influences on the structure and morphology were evaluated. The microwave ...

We report on the synthesis, morphology, chemically and structurally of TiO2-NiO-SiO2 nanostructure. The TiO2-NiO-SiO2 nanostructure was synthesized by a method based on the sol-gel method, by the simultaneous gelation of all cations. The coatings were deposited on dried soda-lime glass slides by spin coating. Composite powders and coating on glass hav...

In this scientific research work we report a novel method to synthesis Co3O4 nanoparticles via calcinations of cobalt hydroxide which can be conveniently prepared by the Co(NO3 )2.6H2O with different reactants. In order to study the effect of calcination temperature on structure and morphology of the nanoparticles, the calcinations take place at various temperatures (at 300°C, 500°C and 700°C)....

Abstract The removal of reactive blue 49 dye on a bio-sorbent material for Natural lemon peels(NLP) and Acid-activated carbon peels(AACLP) from aqueous solutions was studied. Preparation activated by Calcinations at temperature (300°C) one hour chemical activation phosphoric acid. Study different parameter such as effect contact time, adsorbent dose, pH solution, solution Adsorption comparison ...

Abstract The rural and monumental architecture of Northern Spain gives testimony the wide-ranging constructive possibilities traditional gypsum for exterior structural applications. However, today, is only used finishing purposes. By combining a bibliographic review with local visits/interviews experimental calcinations, we were able to document processing methods analyze factors responsible de...

we report on the synthesis, morphology, chemically and structurally of la2o3-co3o4-zro2 nanostructure. the la2o3-co3o4-zro2 nanostructure was synthesized by a method based on the co-precipitation. composite powders have been characterized by xrd (x-ray diffraction), sem (scanning electron microscopy) and bet (brunauer-emmett-teller). x-ray diffraction showed the formation of nano crystalline, l...

CaCO3 nanoparticles have been synthesized via heat-treatment of a new precursor and solid state reaction. Effect of calcinations temperature and quantity of surfactant on particle size has been investigated. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared (FT–IR) spec...
