Simultaneous correlation of VLE, He and Cpe of some diether + n-alkane systems by the Kohler polynomial / Simultano korelisanje VLE, He i Cpe podataka dietar + n-alkan sistema pomoću Kohlerovog polinoma
(Serbian Chemical Society, Belgrade, 2006)
The simultaneous correlation of VLE and excess properties (HE, cPE) for diether + n-alkane systems was performed in our previous paper by the cubic equation of state which incorporates the activity coefficient model ...
TPD-MS study of glassy carbon surfaces oxidized by CO2 and O2 / Maseno spektrometrijsko ispitivanje stabilnosti površine staklastog karbona oksidovanog ugljen-dioksidom ili kiseonikom
(Serbian Chemical Society, Belgrade, 2002)
The temperature-programmed desorption (TPD) method combined with mass spectrometric (MS) analysis has been applied to investigate the surface properties of carbon materials. The apparatus consisting of a temperature-programmed ...
Mass transfer between a fluid and an immersed object in liquid-solid packed and fluidized beds / Prenos mase fluid-uronjeni objekat u pakovanim i fluidizovanim slojevima tečnost-čestice
(Serbian Chemical Society, Belgrade, 2005)
The mass transfer coefficient between fluid and an immersed sphere in liquid packed and fluidized beds of inert spherical particles have been studied experimentally using a column 40 mm in diameter. The mass transfer data ...
A comparative study of two wool enzyme treatments
(Niscair, 2002)
The influence of enzyme concentration and treatment time on certain wool properties has been studied according to the Box-Hunter experimental design in order to better understand the wool modification caused by two different ...
Theoretical assessment of calcium arsenates stability: Application in the treatment of arsenic contaminated waste
(8th Conference of the Yugoslav Materials Research Society, 2007)
Several approaches for immobilization of arsenic (As) based on the transformation of its soluble forms (compounds) into highly insoluble arsenate apatite Ca5(AsO4)3 OH have been proposed. These immobilization techniques ...
Influence of drying constant and diffusivity on clay drying behavior
(Techna Srl, Faenza, 2007)
The influence of the correlation between the drying constant and the diffusion coefficient of the liquid on the behavior of two raw materials for brick manufacturing during their drying process was examined. The test was ...
The influence of a cryoprotective medium containing glycerol on the lyophilization of lactic acid bacteria / Uticaj krioprotektivnog medijuma sa glicerolom na liofilizaciju bakterija mlečne kiseline
(Serbian Chemical Society, 2001)
The aims of lyophilization (freeze-drying) of lactic acid bacteria are to preserve pure cultures or to prepare starters for the dairy industry. In both cases, the choice of the cryoprotectant is very important. In this ...
Osmotic and activity coefficients of the {xZnCl(2)+(1-x)ZnSO4}(aq) system at 298.15 K
(Springer/Plenum Publishers, New York, 2007)
Isopiestic vapor pressure measurements were made for {xZnCl(2)+(1-x)ZnSO4}(aq) solutions with ZnCl2 molality fractions of x=(0,0.3062,0.5730,0.7969, and 1) at the temperature 298.15 K, using KCl(aq) as the reference standard. ...
Hydrothermal synthesis and structure of a new layered zincophosphate intercalated with 3-methylaminopropylamine cations / Hidrotermalna sinteza i struktura jednog novog slojevitog cinkofosfata interkaliranog sa 3-metilaminopropilamin-katjonom
(Serbian Chemical Society, Belgrade, 2005)
A novel layered zincophosphate (ZnPO–MPA) was prepared by hydrothermal crystallization using 3-methylaminopropylamine (MPA) as a structure-directing agent. The structure consists of macroanion [Zn2P3O8(OH)3]2- layers which ...
The retention behavior of some uracil derivatives in normal and reversed-phase chromatography. Lipophilicity of the compounds
(Research Inst Medicinal Plants, Budakalasz, 2005)
The chromatographic behavior of newly synthesized uracil derivatives has been studied by normal and reversed-phase thin-layer chromatography. Benzene-methanol, benzene-acetonitrile, and benzene-isopropanol were used as ...
