Determination of surface coverage of iron-phosphate coatings on steel using the voltammetric anodic dissolution technique / Određivanje pokrivenosti površine čelika gvožđe-fosfatnim prevlakama anodnim rastvaranjem primenom linearne voltametrije
(Serbian Chemical Society, Belgrade, 2013)
In this study, the effect of deposition time and concentration of NaNO2 in the phosphate bath on the surface morphology of iron-phosphate coatings on low carbon steel was investigated using scanning electron microscopy ...
Micro-environmentally restricted hybridoma cell growth within polysaccharide hydrogel microbeads
(IOS Press, Amsterdam, 2013)
The mechanism of micro-environmentally restricted hybridoma cell growth caused by action of local mechanical compression stress generated within various polysaccharide hydrogel matrixes is estimated by comparing the growth ...
Lipase production by Yarrowia lipolytica using olive oil processing wastes as substrates / Proizvodnja lipaze iz Yarrowia lipolytica korišćenjem otpadnih sirovina industrije prerade maslina kao supstrata
(Serbian Chemical Society, Belgrade, 2013)
In this study, the solid and liquid wastes from the olive oil processing industry were evaluated as substrates for Yarrowia lipolytica growth with the aim of lipase production. Olive mill wastewater and olive oil cake ...
Synthesis and characterization of thermosensitive hydrogels and the investigation of modifiedrelease of ibuprofen / Sinteza i karakterizacija termoosetljivih hidrogelova i ispitivanje modifikovanog oslobađanja ibuprofena
(Association of Chemical Engineers of Serbia, 2013)
The method of the synthesis of poly(N-isopropylacrylamide-co-2-hydroxypropyl methacrylate) hydrogels obtained by radical polymerization is described. Their characterization was carried out by the determination of the ...
Lipophilicity assessment of some 5,5-disubstituted hydantoins by the means of reversed phase liquid chromatography / Procena lipofilnosti nekih 5,5-disupstituisanih hidantoina primenom tečne hromatografije na obrnutim fazama
(Association of the Chemical Engineers of Serbia, 2013)
The retention of some 5,5-disubstituted hydantoins was investigated by reversed phase high performance thin-layer chromatography (RP HPTLC) and reversed phase high-pressure liquid chromatography (RP HPLC). The mobile phases ...
Enzymatic synthesis of a vitamin B6 precursor / Enzimska sinteza prekursora vitamina B6
(Serbian Chemical Society, Belgrade, 2013)
3-Cyano-4-(ethoxymethyl)-6-methyl-2-pyridone, an important precursor in the synthesis of vitamin B6, is obtained in the addition reaction between 2-cyanoacetamide and 1-ethoxy-2,4-pentanedione catalyzed by lipase from ...
Two-Stage Fermentation for 2-Ketogluconic Acid Production by Klebsiella pneumoniae
(Korean Soc Microbiology & Biotechnology, Seoul, 2014)
2-Ketogluconic acid production by Klebsiella pneumoniae is a pH-dependent process, strictly proceeding under acidic conditions. Unfortunately, cell growth is inhibited by acidic conditions, resulting in low productivity ...
Calculation and optimization of the copper (II) sulphate monohydrate from copper (II) sulphate pentahydrate production process in a fluidized bed dryer / Proračun i optimizacija procesa proizvodnje bakar(II)-sulfat-monohidrata iz bakar(II)-sulfat-pentahidrata u sušnicama sa fluidizovanim slojem
(Association of Chemical Engineers of Serbia, 2015)
In this paper the process of the copper (II) sulphate monohydrate from copper (II) sulphate pentahydrate (also known as a Blue vitriol or Bluestone) production was analyzed. Copper (II) sulphate pentahydrate is one of the ...
Removal of Mg from spring water using natural clinoptilolite
(Mineralogical Soc, Twickenham, 2012)
Natural zeolitic tuff from Brus (Serbia) consisting mostly of clinoptilolite (about 90%) has been investigated for the reduction of the Mg concentration in spring water. The sorption capacity of the zeolite is relatively ...
