Preparation and characterization of chrome doped sphene pigments prepared via precursor mechanochemical activation
(Journal of Alloys and Compounds, 2013)
Mechanical activation of precursors has been used for the preparation of Cr-doped sphene ceramic pigments (CaTi1-yCrySiO5). Ceramic material has been prepared from a powder mixture of CaCO3, TiO2, SiO2 and Cr(NO3)center ...
Room-Temperature Synthesis and Photocatalytic Activity of Titania Nanoparticles Doped with Gadolinium Ions
(Digest Journal of Nanomaterials and Biostructures, 2013)
Gd3+-doped titania nanoparticles have been synthesized via acidic hydrolysis of Gd3+ and Ti4+ organic precursors. The resulting products were characterized by X-ray diffraction, transmition electron microscopy and diffuse ...
Representativity of Air Quality Control in Limited Number of Grid Points
(Journal of Environmental Protection and Ecology, 2014)
In this study, we point to loss of accuracy in representing a field of air pollution concentration due to reduction of number of monitoring points or changes in their location. Using a Gaussian-type diffusion model, a high ...
Determination of glass temperature of polymers by inverse gas chromatography
(Journal of Chromatography A, 2008)
Inverse gas chromatography (IGC) is an attractive technique for polymer characterization due to possible simultaneous determination of various physicochemical properties of polymer systems merely from retention times of ...
