Noble metal binding on macroporous poly(GMA-co-EGDMA) modified with ethylenediamine / Vezivanje plemenitih metala za makroporozni poli(GMA-co-EGDMA)kopolimer modifikovan sa etilendiaminom
(Serbian Chemical Society, Belgrade, 2004)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), p(GME), was synthesized by suspension copolymerization and modified by reaction of the pendant epoxy groups with ethylenediamine. The ...
Saturated-liquid heat capacity of organic compounds: New empirical correlation model / Toplotni kapacitet zasićene tečnosti organskih jedinjenja - nov empirijski korelacioni model
(Serbian Chemical Society, Belgrade, 2004)
A new saturated-liquid heat capacity model is recommended. This model is tested and compared with the known polynomial and quasi-polynomial models on 39 sets with 1453 experimental heat capacity data. The obtained results ...
Osmotic and activity coefficients of {yKCl+(1-y)MgCl2}(aq) at T=298.15 k
(Springer/Plenum Publishers, New York, 2007)
Isopiestic vapor-pressure measurements were made at the temperature 298.15 K for aqueous KCl + MgCl2 solutions using KCl(aq) as the reference standard. The measurements for these ternary solutions were made at KCl ionic ...
Activity and stability of RuO2-coated titanium anodes prepared via the alkoxide route / Aktivnost i stabilnost titanskih anoda sa prevlakom od oksida rutenijuma dobijenom alkoksidnim postupkom
(Serbian Chemical Society, Belgrade, 2006)
Titanium anodes with an active RuO2 coating of two different thicknesses were prepared from the oxide suspended in ethanol ("ink" method), while the oxide itself was synthesized by the hydrolysis of ruthenium ethoxide in ...
Lipase immobilization in a hollow fibre membrane reactor: Kinetics characterization and application for palm oil hydrolysis
(Versita, Warsaw, 2004)
Feasibility of lipase immobilization in a hydrophilic hollow fibre membrane reactor for oil hydrolysis has been demonstrated. A simple immobilization technique was applied resulting in about 155 mg m(-2) of immobilized ...
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 ...
Removal of metal cations from wastewater using recycled wool-based non-woven material / Uklanjanje katjona metala iz otpadne vode netkanim materijalom na bazi vune kao sekundarne sirovine
(Serbian Chemical Society, Belgrade, 2007)
In this study, the effect of low-temperature air plasma, biopolymer chitosan and hydrogen peroxide treatment of recycled wool-based non-woven material on metal cation uptake was investigated. Recycled wool-based material ...
Formation of oxygen complexes in controlled atmosphere at surface of doped glassy carbon
(Indian Acad Sciences, Bangalore, 2006)
The effects of boron and phosphorus incorporation in phenolic resin precursor to the oxidation resistance of glassy carbon have been studied. In order to reveal the nature and composition of the oxygen complexes formed at ...
