Synthesis of TiO2 nanopowder via a low cost ultrasonic spray pyrolysis technique is reported and the nanopowder is used for the surface modification of glassy carbon electrode. The structural characterization of nanopowder by high temperature XRD clearly shows the phase transformation from anatase to rutile phase on increasing temperature. The morphological structure is characterized by field e...

Nanosized Powders are known to have very useful applications in the areas of medical, structural, chemical and other various fields because of their enhanced physical, optical, and magnetic properties. Several Synthesis methods have been developed for the production of nanopowders. This paper will discuss different methods used for the production of nanosized powders and their advantages and di...

The nanoparticle technologies consisting of multiple layers of mixtures of activated carbon and ruthenium (IV) oxide for super capacitors are reported. The mono-particulate layer process described here is a modified Langmuir-Blodgett trough. We report the processes for a spray-coated zinc nanopowder electrode used as a counter-electrode forming a galvanic cell of extremely high charge storage c...

Though press and sinter powder metallurgy (PM) steel offers cost-effective solutions for structural applications, there is a constant drive improvement in their density. Addition of nanopowder to the conventional micrometre-sized metal explored improve In this study, effect addition varying amounts has been studied. Carbonyl iron (<5 ?m) water atomized (<45 were used as base which (<100 nm) was...

TiO2—methylcellulose (MC) nanocomposite films processed by the sol-gel technique were studied for phocatalytic applications. Precalcined TiO2 nanopowder was mixed with a sol and heat treated. The sol suspension was prepared by first adding titanium tetra isopropoxide (Ti(OPr)4 or TTP) to a mixture of ethanol and HCl (molar ratio TTP:HCl:EtOH:H2O = 1:1.1:10:10) and then adding a 2 wt.% solution ...

the cytotoxicity of the biomaterials is a key issue that should be addressed prior to pre-clinical applications. this study was designed to evaluate and compare the cytotoxixity of two forms of bioactive glasses:nanopowder:andmicropowder. human hgf1-pi53 gingival fibroblast cells were used to evaluate the cytotoxicity of 0.5, 1, 1.5, 2, 5, 10, 15 and 20 mg/ml concentrations of the two bioactive...
