Comparative analyses of the diffusion coefficients from thyme for different extraction processes / Uporedna analiza koeficijenata difuzije za različite procese ekstrakcije iz tamjana
(Serbian Chemical Society, Belgrade, 2012)
This work was aimed at analyzing the kinetics and mass transfer phenomena for different extraction processes from thyme (Thymus vulgaris L.) leaves. Different extraction processes with ethanol were studied, i.e., Soxhlet ...
A study of the antibacterial activity and stability of dyed cotton fabrics modified with different forms of silver / Ispitivanje antibakterijske aktivnosti i stabilnosti obojene pamučne tkanine modifikovane različitim formama srebra
(Serbian Chemical Society, Belgrade, 2012)
This study compares the effect of colloidal silver nanoparticles and the commercial RUCO-BAC AGP agent with silver chloride as the active component on the antibacterial activity of dyed cotton fabrics. Cotton fabrics were ...
Effects of solvent and structure on the reactivity of 2-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents / Efekti strukture i rastvarača na reaktivnost 2-supstituisanih nikotinskih kiselina sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2012)
The rate constants for the reactions of diazodiphenylmethane (DDM) with 2-substituted nicotinic acids in nine aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents were ...
Zinc removal from wastewater by a complexation-microfiltration process / Uklanjanje cinka iz otpadnih voda kompleksirajuće-mikrofiltracionim procesom
(Serbian Chemical Society, Belgrade, 2012)
Due to its wide industrial applications, zinc has become an important contaminant in aquatic environments since it is a toxic heavy metal and some of its compounds, such as zinc arsenate and zinc cyanide, may be extremely ...
The substituent effects on the 13C chemical shifts of the azomethine carbon atom of N-(substituted phenyl)salicylaldimines / Efekat supstituenata na 13C hemijska pomeranja azometinskog ugljenika N-(supstituisani fenil)saliciladimina
(Serbian Chemical Society, Belgrade, 2012)
Hammett correlations between the 13C-NMR chemical shifts of the azomethine carbon atom and the corresponding substituent constants were established for thirteen Schiff bases. The successful correlation of the chemical ...
Antimicrobial oxidized hemp fibers with incorporated silver particles / Antimikrobna tempo-oksidisana vlakna konoplje sa inkorporisanim česticama srebra
(Serbian Chemical Society, Belgrade, 2012)
In this study, antimicrobial silver-loaded hemp fibers were prepared by selective TEMPO-mediated oxidation, i.e., oxidation with sodium hypochlorite, catalytic amount of sodium bromide and the 2,2,6,6-tetramethylpipe-ridine-1-oxy ...
