Development of ion chromatography methods for the determination of trace anions in ultra pure water from power plants / Razvoj metoda jonske hromatografije za određivanje tragova anjona u ultra čistim vodama iz termoelektrana
(Serbian Chemical Society, Belgrade, 2005)
A suppressed ion chromatography (IC) technique, using a carbonate/hydrogen carbonate or a hydroxide eluent, has been evaluated as a monitoring tool for the detection of major anions (F-, Cl-, NO3-, PO43- and SO42-) in ultra ...
Nonlinear frequency response of a chromatographic column. part I: Application to estimation of adsorption isotherms with inflection points
(Taylor & Francis Inc, Philadelphia, 2005)
A new method to determine adsorption isotherms is suggested. The method is based on analysis of the nonlinear frequency response of a chromatographic column. Due to the fact that higher order frequency response functions ...
Saturated-liquid heat capacity calculation of alkanes / Predskazivanje toplotnog kapaciteta zasićene tečnosti alkana
(Serbian Chemical Society, Belgrade, 2005)
An empirical model for the calculation of the heat capacity of alkanes is recommended. This model was tested and compared to known models (Luria-Benson and Růžička-Domalski) using 68 sets with 1155 literature experimental ...
Aramid fiber reinforced laminar thermoplastic composite materials
(Journal of Advanced Materials, 2005)
In order to obtain a composite material with desired improved resistance to penetration of ballistic projectile, a poly(p-phenyleneterephthalamide) reinforced laminar thermoplastic composite material has been made. This ...
Using the image analysis program for prediction of thermal stability behavior of refractory specimen
(8th International Symposium on Multifunctional and Functionally Graded Materials, FGM2004, 2005)
Most important properties which are usually measured for refractories are work temperature and thermal stability. Thermal stability of the alumina based samples was measured using a standard laboratory procedure, the water ...
Influence of heat treatment on mechanical and sorptional properties of viscose-based nonwovens
(Niscair, 2005)
The influence of heat treatment on sorptional and mechanical properties of viscose: polypropylene (90:10) blend nonwoven fleeces has been studied. It is observed that the heat treatment improves mechanical properties ...
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 ...
Comparative potentiodynamic study of nickel and hydrogen underpotential deposition at polycrystalline platinum electrode in weak acid and neutral solutions
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Underpotential deposition of nickel and hydrogen on polycrystalline platinum in weak acid and neutral solutions (3.5 lt = pH lt = 7.0), with and without Ni2+-ions, has been examined using cyclic voltammetric technique ...
Composition and antimicrobial activity of essential oil of Satureja montana L. collected in Serbia and Montenegro
(Allured Publ Corp, Carol Stream, 2005)
The chemical composition of the essential oil of Satureja montana L. subsp. montana (Lamiaceae), obtained from the air-dried plant material by hydrodistillation, was analyzed using GC and GUMS. The major components were ...
Properties of dispersion-hardened copper made by internal oxidation of prealloyed copper powder containing 2.5wt. % Al
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Prealloyed copper powder containing 2.5wt. %Al was processed in a planetary ball mill to evaluate matrix hardening due to formation of Al2O 3 particles in situ by internal oxidation. After milling, the powders were heat ...
