(Serbian Chemical Society, Belgrade, 2009)
In this study, the influence of dyeing on the antibacterial efficiency of polyamide and polyester fabrics loaded with colloidal Ag nanoparticles and the influence of the presence of Ag nanoparticles on the color change of ...
Comparative study on biochemical activity of the intestinal isolates Lactobacillus sp. V3 and Bifidobacterium sp. A71 in different substrates / Uporedna ispitivanja biohemijske aktivnosti intestinalnih izolata Lactobacillus sp. V3 i Bifidobacterium sp. A71 u različitim supstratima
(Serbian Chemical Society, Belgrade, 2001)
The two intestinal isolates Lactobacillus sp. V3 and Bifidobacterium sp. A71 were selected for soymilk fermentation according to their acidification activity in soymilk. Beetroot juice and carrot juice were chosen for ...
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 ...
Vapor-liquid equilibria of triglycerides-methanol mixtures and their influence on the biodiesel synthesis under supercritical conditions of methanol / Ravnoteža para-tečnost za sistem trigliceridi-metanol i njen uticaj na kinetiku sinteze biodizela pod uslovima natkritičnog metanola
(Serbian Chemical Society, Belgrade, 2007)
The non-catalytic synthesis of biodiesel (fatty acids methyl esters) from triglycerides and methanol proceeds at elevated pressures above 100 bar and temperatures above 523 K. Kinetic investigations of the system revealed ...
Photoelectrochemical properties of sol-gel obtained titanium oxide / Fotoelektrohemijska svojstva titan-oksida dobijenog sol-gel postupkom
(Serbian Chemical Society, Belgrade, 2008)
The photoelectrochemical properties of a sol-gel prepared titanium oxide coating applied onto a Ti substrate were investigated. The oxide coating was formed from an inorganic sol thermally treated in air at 350°C. The ...
Simultaneous correlation of the excess enthalpy and W-shaped excess heat capacity of 1, 4-dioxane- n-alkane systems by PRSV-HVOS CEOS / Simultano korelisanje dopunske entalpije i dopunskog toplotnog kapaciteta sa w-oblikom eksperimentalnih tačaka kod sistema 1,4-dioksan+n-alkani pomoću prsv-hvos ceos
(Serbian Chemical Society, Belgrade, 2003)
In this work the Peng-Robinson-Stryjek-Vera (PRSV) equation of state coupled with the Huron-Vidal-Orbey-Sandler (HVOS) rule was tested for the correlation of the excess enthalpy (HE) and the excess heat capacity (cp E) ...
Temperature dependence of the Kovats retention indices for alkyl 1, 3-diketones on a DB-5 capillary column / Temperaturna zavisnost kovačevih retencionih indeksa 1,3-diketonan a DB-5 kapilarnoj koloni
(Serbian Chemical Society, Belgrade, 2004)
A series of alkyl 1,3-diketones were used to study the temperature dependence of the Kovats retention indices in the temperature range 130–190 ºC (403–463 K). The temperature dependence is described by the empirical equation ...
