Production of lipase from Pseudozyma aphidis and determination of the activity and stability of the crude lipase preparation in polar organic solvents / Proizvodnja lipaze iz Pseudozyma aphidis i utvrđivanje aktivnosti i stabilnosti lipaze u polarnim organskim rastvaračima
(Serbian Chemical Society, Belgrade, 2011)
The production of lipase from Pseudozyma aphidis (DSM 70725) was determined in six different media. The highest lipase production was observed in a medium with glucose as the sole carbon source, and yeast extract and sodium ...
Corrosion of an austenite and ferrite stainless steel weld / Korozija zavarenog spoja austenitnog i feritnog nerđajućeg čelika
(Serbian Chemical Society, Belgrade, 2011)
Dissimilar metal connections are prone to frequent failures. These failures are attributed to the difference in the mechanical properties across the weld, the coefficients of thermal expansion of the two types of steels ...
Physical, chemical and structural effects as important factors for the determination of thermodynamic and transport properties and the modelling of non-electrolyte solutions / Fizički, hemijski i strukturni efekti kao važni faktori za određivanje i modelovanje termodinamičkih i transportnih svojstava neelektrolitnih rastvora
(Serbian Chemical Society, Belgrade, 2013)
In our previous review, an attempt was made to relate the volumetric effects involved in binary mixtures of normal and branched alcohols. The present paper summarizes some selected research activities related to complex ...
Electrochemical synthesis of silver nanoparticles in poly(vinyl alcohol) solution / Elektrohemijska sinteza nanočestica srebra u rastvoru poli(vinil alkohola)
(Serbian Chemical Society, Belgrade, 2013)
In this work, silver/poly(vinyl alcohol), Ag/PVA, colloidal dispersions were obtained by electrochemical reduction of Ag+. The electrochemical synthesis of silver nanoparticles in aqueous solutions of 5 and 10 wt. % PVA, ...
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 ...
Simple one-pot synthesis of thioureas from amines, carbon disulfide and oxidants in water
(Srpsko hemijsko društvo, Beograd, 2016)
The present study reports a new facile methodology for the synthesis of symmetrical and asymmetrical thioureas by a one-pot reaction of the required amine, carbon disulfide and an oxidant, i.e., hydrogen peroxide, ...
The influence of substituted aromatic aldehydes on the electrodeposition of Zn-Mn alloy / Uloga supstituisanih aromatičnih aldehida u elektrohemijskom taloženju Zn-Mn legura
(Serbian Chemical Society, Belgrade, 2013)
Additives are necessary in the electrodeposition of Zn-Mn alloys at high current densities, in order to reduce the hydrogen evolution reaction and prevent dendrite formation. The influences of two aromatic aldehydes, ...
