Solid State Synthesis of Extra Phase-Pure Li4Ti5O12 Spinel
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
Extra phase-pure Li4Ti5O12 spinel with particle sizes less than 500 nm was synthesized by solid state reaction of mechanochemicaly activated mixture of nano anatase and Li2CO3 for a very short annealing time, 4 h at 800 ...
Fatty Acids of Some Moss Species from Germany
(Asian Journal Of Chemistry, Sahibabad, 2011)
The fatty acid composition of three mosses collected in Germany was preliminary analyzed by gas chromatography (GC-FID) and gas I chromatography-mass spectrometry (GC-MS) for the first time. It was found that Hypnum ...
Comparative research of accumulation of heavy metals in woody plants and herbs
(Parlar Scientific Publications (P S P), Freising, 2011)
Vascular plants can precisely indicate the presence and intensity of different pollutants (heavy metals, chemical substances etc.) in air and soil in natural ecosystems as well as in the urban environments. The accumulation ...
