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 ...
A comparative study of the linear solvation energy relationship for the reactivity of pyridine carboxylic acids with diazodiphenylmethane in protic and aprotic solvents / Komparativna studija linearne korelacije slobodnih energija za reaktivnost piridin-karboksilnih kiselina sa diazodifenil-metanom u protičnim i aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2012)
The effects of protic and aprotic solvents on the reactivity of picolinic, nicotinic and isonicotinic acid, as well as of some substituted nicotinic acids, with diazodiphenylmethane (DDM) were investigated. In order to ...
Electrochemical impedance spectroscopy of a silver-doped hydroxyapatite coating in simulated body fluid used as a corrosive agent / Spektroskopija elektrohemijske impedancije prevlake hidroksiapatita dopirane srebrom u simuliranoj telesnoj tečnosti korišćenoj kao korozioni agens
(Serbian Chemical Society, Belgrade, 2012)
Titanium is a key biomedical material due to its good biocompatibility, mechanical properties and corrosion stability, but infections at the implantation site still pose a serious threat. One approach to prevent infection ...
Separation and determination of dimethylarsenate in natural waters / Razdvajanje i određivanje dimetilarsenata u prirodnim vodama
(Serbian Chemical Society, Belgrade, 2012)
A simple and efficient method for the separation and determination of dimethylarsenate DMAs(V) was developed in this work. Two resins, a strong base anion exchange (SBAE) resin and iron-oxide coated hybrid (HY) resin were ...
