Optimization of (-galactosidase production from lactic acid bacteria / Optimizacija proizvodnje (-galaktozidaze pomoću bakterija mlečne kiseline
(Association of Chemical Engineers of Serbia, 2015)
(-galactosidase, commonly known as lactase, represents commercially important enzyme that is prevalently used for lactose hydrolysis in milk and whey. To the date, it has been isolated from various sources. In this study ...
Opportunities, perspectives and limits in lactic acid production from waste and industrial by-products
(Savez hemijskih inženjera, Beograd, 2016)
In line with the goals of sustainable development and environmental protection today great attention is directed towards new technologies for waste and industrial by-products utilization. Waste products represent potentially ...
Connecting science and industry with improved communication of research results
(Savez hemijskih inženjera, Beograd, 2019)
Fenton process in dispersed systems for industrial wastewater treatment
(Savez hemijskih inženjera, Beograd, 2019)
Industrial wastewater contains recalcitrant organic compounds with a very complex chemical structure, built of molecules with long chains of carbon atoms and attached different functional groups. Chemical or biological ...
Polypyrrole vertical bar zinc supercapattery with the aqueous electrolyte
(Savez hemijskih inženjera, Beograd, 2017)
Polypyrrole (PPY) electrode was obtained by electrochemical oxidative polymerization of pyrrole on graphite electrode from aqueous electrolyte containing 0.1 mol dm(-3) pyrrole monomer and 1.0 mol dm(-3) HCl. Polymerization ...
Cracking caused by cutting of plasma-sprayed hydroxyapatite coatings and its relation to the structural features of coatings deposited at different initial substrate temperatures
(Savez hemijskih inženjera, Beograd, 2017)
The present study estimated the cracking phenomenon in as-plasma-sprayed hydroxylapatite coatings (HACs) after they were being subjected to the severe cutting conditions in the direction perpendicular to the coating/substrate ...
The influence of migration processes in gunpowder charge on the quality of mortar ammunition
(Savez hemijskih inženjera, Beograd, 2017)
The study describes the results of static, physicochemical and ballistic examination of double-based gunpowder charges, in order to establish the deviations from the demanded quality of mortar ammunition. The examinations ...
Spectroscopic and quantum chemical elucidation of newly synthesized 1-aryl-3-methyl-3-phenylpyrrolidine-2,5-diones as potential anticonvulsant agents
(Savez hemijskih inženjera, Beograd, 2019)
Novel succinimide derivatives were synthesized from 3-methyl-3-phenylsuccinic acid and substituted anilines under solvent-free conditions by using microwave irradiation. All obtained compounds were characterized by ultraviolet ...
Analysis of selected elements in water in the drinking water preparation plants in Belgrade, Serbia / Analiza odabranih elemenata u vodi u pogonima za pripremu vode za piće u Beogradu
(Association of Chemical Engineers of Serbia, 2011)
Belgrade's water supply relies mainly on the River Sava and groundwater supply wells, which are located in the vicinity of the river and Ada Ciganlija. In this paper, the contents of aluminum, boron, chromium, manganese, ...
Image analysis as a useful tool for fast detection of dimensional and structural changes of poly(ethylene terephthalate) containers
(Savez hemijskih inženjera, Beograd, 2018)
The aim of this paper is to present image analysis as a useful technique for fast, reliable and non-destructive detection of dimensional and structural changes in polymers. The possibility of applying image analysis was ...
