Zirconia stabilized by addition of bismuth oxide was prepared by co precipitation process from metal oxide chlorides using sodium hydroxide. The dried gels produced pure phase ZrO2-Bi2O3 powders on calcination at 800ºC for the co precipitated powders. The phase evolution was stud...
The synthesis and characterization of two new ruthenium diporphyrazines is reported. The ruthenium (III) chloride in cyclotetramerization reaction with 5,6-diphenylpyrazine-2,3- dicarbonitrile or 1,2-dicyanobenzene resulted the green and blue diporphyrazinato counterparts respect...
Aims: 222Rn, a radioactive inert gas is a large component of the natural radiation that humans are exposed to, can pose a threat to the public health when it accumulates in poorly ventilated residential and occupational settings. About half of the total radiation effective dose t...
New layered compounds of Aluminium (III) and Chromium (III) phosphonates, were synthesized by combining aqueous solution of M(NO3)3.5H2O (M=Cr or Al) and aqueous solution of 3- phosphonopropionic Acid. The phosphonates were characterized by infra-red Spectroscopy.The IR Spectra o...
Aims: Researches into a host of energy deployment options and creative policy initiatives continue in respect of renewable energy and this paper highlights some of the recent advances observed. It investigates the potentials of some second generation biofuels such as manure, tube...
Road Traffic Noise is causing huge socio-economic losses to the nations all around the world by lowering the quality of life and property values. India, poised with the annual projected automotive industry growth of 12% to 15% for 2011-12 and ever increasing traffic on its roads...
The phytoremediation can be used to recover precious metals like gold, silver, platinum and palladium, indicating that there is a wide opportunity for use it as a remediation technology in mining. The alfalfa alive was used to reduce the silver and forming silver nanoparticles Ag...
Heavy metals are found naturally in the soil in small concentrations. These can be collected in bigger amounts by mining, agriculture, industry, and others. Also plants can processes these in toxicity levels and if putted into the food chain, human physiologic integrity is affect...
The meaning of Lorentz “local time” is reconsidered in the classical physics. Set up two inertial reference frames S and S', the frame S' is moving at a velocity v relative to frame S in the x direction. When the origin of frame S' passes the origin of frame S, the clocks at the...
Heat flow stability profiles in the presence of external thermal field require careful qualitative treatment. The computational data must be considered to agree with realistic models. A hexagonal plate endowed with the thermal and material properties of a pure metal was chosen as...
