The nanocrystallization of Co67Fe4Cr7Si8B14 amorphous ribbons which prepared by planar flow melt spinning process (PFMS) was investigated. Crystallization of the ribbons was studied by differential thermal analysis (DTA), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The DTA result of amorphous ribbon at heating rate of 10˚C/min showedoccurrence of phase transitions in two...

tellurium nanostructures have been prepared by physical vapor deposition method in a tube furnace. the experiments were carried out under argon gas flow at a pressure of 1 mbar. tellurium powder was evaporated by heating at 350°c and 430°c and was condensed on substrates at 110–250°c, in the downstream of argon gas flow. the products were characterized by field emission scanning electron micros...

In this research we report synthesis of new Barium- Cobalt precursor complex with 2,6- pyridine dicarboxylic acid (dipic).Thecomplex[Ba(H2O)6][Co(dipic)2[(1)has been characterized using spectral methods (FT-IR, UV–Vis),elemental analysis and Cyclic voltammetric (CV) method. Also in this study we report thermal decomposition of inorganic precursor complex of (1).Characterization of the binary ox...

a simple method has been employed to synthesize copper and copper oxide nanoparticles from copper (ii) succinate precursor by thermal decomposition method using oleylamine as a capping agent. the particles synthesized with oleylamine and triphenylphosphine were well dispersed nanoparticles obtained from x-ray diffraction (xrd). the synthesized copper nanoparticles were characterized by uv-visib...

Chemical reduction technique was used to synthesize nickel powder using hydrazine hydrate as reducing agent, nickel chloride hexahydrate as precursor and polyvinylpyrrolidone (PVP) as capping agent in ethylene glycol medium. Experiments were carried out with mole ratios 13:1 and 20:1 of hydrazine to nickel chloride hexahydrate by keeping the amounts of ethylene glycol and NaOH as constant. Vari...

Nanoparticles are widely used in different applications such as cancer cell treatment and antibacterial agents. SnO2 nanoparticles were synthesized successfully by hydrothermal method and subsequent calcination using Tin (II) chloride- dihydrate, Sodium hydroxide, in presence of Hexadecyltrimethylammoniumn bromide (CTAB) as Surfactant. These nanoparticles were characterized by using Fourier tra...
