A study of the antibacterial activity and stability of dyed cotton fabrics modified with different forms of silver / Ispitivanje antibakterijske aktivnosti i stabilnosti obojene pamučne tkanine modifikovane različitim formama srebra
(Serbian Chemical Society, Belgrade, 2012)
This study compares the effect of colloidal silver nanoparticles and the commercial RUCO-BAC AGP agent with silver chloride as the active component on the antibacterial activity of dyed cotton fabrics. Cotton fabrics were ...
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 ...
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 ...
Effects of solvent and structure on the reactivity of 2-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents / Efekti strukture i rastvarača na reaktivnost 2-supstituisanih nikotinskih kiselina sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2012)
The rate constants for the reactions of diazodiphenylmethane (DDM) with 2-substituted nicotinic acids in nine aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents were ...
Zinc removal from wastewater by a complexation-microfiltration process / Uklanjanje cinka iz otpadnih voda kompleksirajuće-mikrofiltracionim procesom
(Serbian Chemical Society, Belgrade, 2012)
Due to its wide industrial applications, zinc has become an important contaminant in aquatic environments since it is a toxic heavy metal and some of its compounds, such as zinc arsenate and zinc cyanide, may be extremely ...
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 ...
