Investigations of the reactivity of pyridine carboxylic acids with diazodiphenylmethane in protic and aprotic solvents, Part I: Pyridine mono-carboxylic acids / Ispitivanje reaktivnosti piridin-monokarbonskih kiselina u reakciji sa diazodifenilmetanom u protičnim i aprotičnim rastvaračima. Deo I
(Serbian Chemical Society, Belgrade, 2005)
Rate constants for the reaction of diazodiphenylmethane with isomeric pyridine carboxylic acids were determined in chosen protic and aprotic solvents at 30 °C, using the well known UV spectrophotometric method. The values ...
Surface characterization of polymers by inverse gas chromatography
(Srpsko hemijsko društvo, Beograd, 2007)
An inverse gas chromatographic (IGC) study of the sorption properties of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), PGME, and PGME modified with ethylene diamine, PGME-en, was ...
The mechanism of cathodic electrodeposition of epoxy coatings and the corrosion behaviour of the electrodeposited coatings / Mehanizam kataforetskog taloženja epoksidnih prevlaka i koroziono ponašanje dobijenih prevlaka
(Serbian Chemical Society, Belgrade, 2002)
The model of organic film growth on a cathode during electrodeposition process proposes the current density-time and film thickness-time relationships and enables the evaluation of the rate contents for the electrochemical ...
Histological and immunohistochemical evaluations of rat soft tissue response to bioceramical implants / Histološka i imunohistohemijska procena reakcije mekog tkiva pacova na biokeramičke implante
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2009)
The purpose of this study was to evaluate the tissue response induced by bioceramical materials (BCM) implanted in rat subcutaneous tissue. Thirty two rats were assigned to 6 groups, as following: control group i.e. not ...
Damage detection of hybrid aramid/metal-PVB composite materials using optical fiber sensors
(Association of the Chemical Engineers of Serbia, 2009)
Embedding optical fiber sensors within laminar thermoplastic composite material results in forming a system known as 'smart structure'. These sensors present the information about the inner structure health during the ...
Heavy metals concentration in soils from parks and green areas in Belgrade / Koncentracija teških metala u zemljištu parkova i zelenih površina u Beogradu
(Serbian Chemical Society, Belgrade, 2009)
The current study included the investigation of several metals and their distribution in urban soils from parks and green areas in the city of Belgrade. The soils were sampled in January and February 2008. The concentrations ...
Optimization of the procedure for the synthesis of calcium and sodium citrate in laboratory and semi-industrial conditions / Optimizacija postupka sinteze kalcijum i natrijum-citrata u laboratorijskim i poluindustrijskim uslovima
(Association of Chemical Engineers of Serbia, 2009)
The aim of this investigation is the development of the optimal laboratory procedure for the synthesis of calcium and sodium citrate and the application of obtained results in a project for a semi-industrial installation ...
Saturated-liquid heat capacity: New polynomial models and review of the literature experimental data / Toplotni kapacitet zasićene tečnosti - novi polinomski modeli i pregled literaturnih podataka
(Serbian Chemical Society, Belgrade, 2003)
In this paper a review of selected literature experimental data for saturated-liquid heat capacities was presented. Two-, three- and four-parameter polynomial correlation models are tested on those data. Obtained results ...
