This PhD thesis presents the possibility of nanostructured composite materials based on copper and alumina synthesis trough a new method, which is a combination of thermo-chemical synthesis and mechanical alloying. ...
Determination of drug residues in water by liquid chromatography – tandem mass spectrometry / Određivanje tragova lekova u vodi metodom tečne hromatografije sa tandem masenom spektrometrijom
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2009)
The presence of drug residues in the environment has become a subject of growing concern in the past decade. Wastewater treatment plants are not designed to remove drugs from the effluents and consequently they are released ...
Linear Free Energy Relationships of the C-13 NMR chemical shifts in 5-(3-and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones
(Arkat Usa Inc, Gainesville, 2009)
The C-13 NMR chemical shifts of the C2 carbon atom in the heteroaromatic nuclei of seventeen 5-(3- and 4-substituted arylazo)-4,6-dimethyl-3-cyano-2-pyridones were determined in deuterated DMSO solution. For quantitative ...
