Aspirin polyrnorphs, exist or not?
(Elsevier, Amsterdam, 2004)
Energy and economy savings in the process of methanol synthesis unsig Pinch technology / Energetsko i ekonomsko poboljšanje procesa sinteze metanola primenom Pinch tehnologije
(Serbian Chemical Society, Belgrade, 2004)
A heat exchanger network (HEN) for the process of methanol synthesis has been studied by pinch design analysis. Great economic and energy savings were realized by the pinch analysis in comparison to the existing plant. ...
Synthesis of new hyperbranched urethane-acrylates and their evaluation in UV-curable coatings
(Elsevier Science Sa, Lausanne, 2004)
Three series of hyperbranched urethane-acrylates (HB-UA), based on aliphatic hyperbranched polyesters and polyethyleneglycol acrylate, were prepared and evaluated for use in UV-curable coatings. UV-curing kinetics were ...
Protective properties of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Fe alloys / Zaštitna svojstva epoksidnih kataforetskih prevlaka na čeliku elektrohemijski modifikovanom Zn-Fe legurama
(Association of Chemical Engineers of Serbia, 2004)
Epoxy coatings were electrodeposited on steel and steel modified by Zn-Fe alloys using the constant voltage method. Zn-Fe alloys were electrodeposited on steel at different current densities. The effect of the Zn-Fe alloy ...
Kinetics of the reaction of 5-substituted orotic acids with diazodiphenylmethane / Kinetika reakcije 5-supstituisanih orotinskih kiselina sa dizaodifenilmetanom
(Serbian Chemical Society, Belgrade, 2004)
Rate konstants for the reaction of eight 5-substituted orotic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) were determined at 30 ºC by the known spectrophotometricmethod. The determined rate constants ...
Polyacrylamide and poly(itaconic acid) complexes
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
Intermolecular complex formation through hydrogen bonding between poly(itaconic acid), partially neutralized and non-neutralized, and polyacrylamide was studied by potentiometry. The complexes were obtained by template ...
Obtaining crystals in a laboratory furnace
(Elsevier, Amsterdam, 2004)
A model of an air cooler (telescopic cold bridge) with a column of Tamman test tubes (telescopic test comb), installed in a laboratory tube furnace, for regulation and simultaneous crystallization tests at different ...
Expressing the reliability of the process technologies components / Izražavanje pouzdanosti opreme u procesnim tehnologijama
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2004)
Every process defined within a specific technology necessitates the exploitation of equipment with a large variety in structures. Procedures in the technology define the purpose of the component, and in-service operations ...
Electrochemical deposition and characterization of Zn-Fe alloys / Elektrohemijsko taloženje i karakterizacija Zn-Fe legura
(Serbian Chemical Society, Belgrade, 2004)
Zn–Fe alloy electrochemically deposited on steel under various deposition conditions were investigated using anodic linear sweep voltammetry (ALSV) and X-ray diffraction (XRD) analysis for phase structure determination, ...
Korozija metala - šta je to?
(Engineering Society for Corrosion, Belgrade, Serbia, 2004)
Korozija materijala je opšte poznat i prihvaćen izraz, ali da li se baš tačno zna šta je korozija? Pod pojmom korozija materijala se podrazumeva svako neželjeno razaranje materijala kao posledice delovanja spoljne sredine. ...
