nano-sized titanium dioxide tio2 powder was prepared by new wet chemical route from its precursor titanium (iv) chloride (ticl4) as precursor with isopropoxy alcohol in presence of nitric acid under ambient condition. their morphologies, phase compositions and components of the tio2 nanoparticles were characterized by transmission electron microscopy (tem), field emission scanning electron micr...

The fullerenes, carbon nanotubes, and graphene have enriched the family of carbon allotropes over the last few decades. Synthetic carbon allotropes (SCAs) have attracted chemists, physicists, and materials scientists because of the sheer multitude of their aesthetically pleasing structures and, more so, because of their outstanding and often unprecedented properties. They consist of fully conju...

in this research, tio2 nanoparticles were synthesized by a simple wet chemical method. ticl4 was used as precursor in hydrogen peroxideand ethanol. the tio2 nanoparticles were characterized by transmission electron microscopy (tem), scanning electron microscopy (sem), x-ray diffraction (xrd), electron dispersive spectroscopy (eds) and uv-vis spectrophotometer. the particle size of the as-synthe...

sphere-like shaped cobalt oxide nanoparticles (co3o4) were synthesized by a simple wet chemical method using cobalt chloride as precursor and cetyl trimethylammonium bromide (ctab) as surfactant. their structural and surface morphologial properties were characterized by high resolution transmission electron microscopy (hrtem), field emission scanning electron microscopy (fesem) and x-ray diffra...

the nanoparticles of gold doped with various percentage of copper (cu 10%, 25%, 75%) were synthesized by wet-chemical method at room temperature. copper (ii) sulfate and gold (iii) chloride trihydride was taken as the metal precursor and ascorbic acid as a reducing agent and anhydride maleic as surfactant. the reaction is performed with high-speed stirring at room temperature under nitrogen atm...

Chemical burns account for a small percentage of admissions to burn units. Wet cement is a poorly recognized cause of chemical burn. As the construction industry is growing, individuals will likely have more contact with this material and be more prone to its harmful effects. Wet cement can cause severe full-thickness burns with prolonged contact, but this property is not well known among profe...

Solid electrolytes based on doped cerium oxide, Ce(M)O2-δ (M = rare-earth cations), are of considerable interest for potential use in low temperature solid oxide fuel cells (LTSOFCs) due to its higher ionic conductivity than YSZ based solid electrolyte.  In this research work, crystalline, pure Ce1-xMxO2-δ (where M = Gd or Sm, x = 0.10 or 0.20) based nanoparticles were prepared by chemical prec...

ZnTe quantum dots (QDs) have been very attractive because of their potential applications in optoelectronic devices operating in the blue-green region of the spectrum. This paper describes a convenient one-step synthesis of high-quality ZnTe QDs in high-temperature organic solution with high yield. Anhydrous zinc chloride was dissolved in phenyl ether under argon protection and oleic amine was ...
