Corrosion protection of aluminium by a cataphoretic epoxy coating
(Elsevier Science Sa, Lausanne, 1999)
The corrosion behavior and thermal stability of epoxy coating electrodeposited on aluminium have been investigated during exposure to 3% NaCl. Electrochemical impedance spectroscopy (EIS), gravimetric liquid sorption ...
C-13 NMR spectra of pyridine chalcone analogs
(Elsevier, Amsterdam, 1999)
C-13 NMR spectra of two series of pyridine chalcone analogs were determined in deuterated dimethylsulphoxide (DMSO-d(6)). It was established that these compounds were in more stable E-configurations except for the ...
Reactivity of beta-aroylacrylic acids with diazodiphenylmethane (vol 63, pg 359, 1998)
(Srpsko hemijsko društvo, Beograd, 1999)
Study of the structure of phenol-formaldehyde novolac resins by NMR spectroscopy and gel-permeation chromatography
(Serbian Chemical Society, Belgrade, 1999)
C-13-NMR spectroscopy and gel-permeation chromatography studies were carried out on different samples of typical commercial phenol-formaldehyde novolac resins. Six random novolac resins (NLO 1-6), with decreasing ratios ...
Simultaneous presentation of VLE, H-E and c(p)(E) by the PRSV equation of state with the modified van der Waals one-fluid and Huron-Vidal-Orbey-Sandler mixing rules
(Elsevier, Amsterdam, 1999)
The Stryjek-Vera modification of the Peng-Robinson equation of state with two parameter van der Waals one-fluid mixing rule suggested by Schwartzentruber and Renon (SR) and the Orbey-Sandler modification of the Huron-Vidal ...
Solvent effects on electronic absorption spectra of 3-N-(4-substituted-phenyl)-5-carboxy uracils
(Serbian Chemical Society, Belgrade, 1999)
Absorption spectra of some 3-N-(4-substituted phenyl)-5-carboxy uracils (substiuents: H, Cl, Br, I, Me, Et, OMe, COOH and NO2) were recorded in twelve solvents in the range 200-400 nm. The effects of solvent polarity and ...
The polymerisation kinetics of lower dialkyl itaconates
(Wiley-VCH Verlag Gmbh, Weinheim, 1999)
The free radical polymerisation kinetics of diethyl- (DEI), dipropyl- (DnPI), dibutyl- (DnBI), and dihexyl itaconate (DHI) in the bulk were studied in the temperature range from 50 to 70 degrees C. The concentration of the ...
Investigation of the Microstructure and Distribution of Solute During Solidification of Al-Cu Alloy
(Springer Science and Business Media LLC, 1999)
Phenomenon of solidification process plays an important role in various areas like: crystal growth, casting processes, liquid phase sintering etc. Results presented in this paper contribute to investigation of the influence ...
Osmotic and activity coefficients of {yNaH(2)PO(4)+(1-y)Na2SO4}(aq) at the temperature 298.15 K
(Elsevier Science Bv, Amsterdam, 1999)
The osmotic coefficients of the mixed electrolyte solution {yNaH(2)PO(4) + (1 - y)Na2SO4}(aq) have been measured by the isopiestic method, at the temperature T = 298.15 K. The activity coefficients of NaH2PO4 and Na2SO4 ...
Rerafinacija otpadnih mineralnih transformatorskih ulja
(Savez energetičara Jugoslavije, Beograd, 1999)
Different physical and chemical processes taking place in the transformer or transformer insulation system, are influencing the decrease in the insulating oil quality. After certain period of time, the oil cannot meet the ...
