Examination of rheological properties of fine particles as carriers for controlled drug release
(Taylor & Francis Inc, Philadelphia, 2003)
Development of lipid-based fine particles as potential drug carriers requires detailed investigation of possible effects of these carriers on rheological properties of blood. In this study, we have investigated the influence ...
The effect of hydrogen co-deposition on the morphology of copper electrodeposits. II. Correlation between the properties of electrolytic solutions and the quantity of evolved hydrogen
(Elsevier, 2008)
Formation of irregular deposits by electrodeposition from acid sulfate solutions of various H2SO4 concentrations was examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
Kinetics of the mild steel corrosion protection by polypyrrole-oxalate coating in sulfuric acid solution
(Elsevier Science Sa, Lausanne, 2006)
Kinetics of the mild steel corrosion protection in 0.1 mol dm(-3) H2SO4 by polypyrrole coatings have been investigated by the means of electrochemical impedance spectroscopy (EIS), cyclic voltammetry, polarization measurements ...
Cyclopropyl building blocks in organic synthesis, part 143. A two-step, three-component queuing cascade leading to dihydrobenzoxepine and dihydrobenzazepine derivatives
(Wiley-VCH Verlag Gmbh, Weinheim, 2007)
A palladium-catalyzed reaction of methylenespiropentane (11) with iodobenzene (12) under typical Heck conditions [Pd(OAC)(2), PPh3, Et3N, DMF] produced a mixture of the unstable [3]dendralene 13 and allylidenecyclopropane ...
Effects of solvent and structure on the reactivity of 6-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents / Uticaj rastvarača i strukture na reaktivnost 6-supstituisanih nikotinskih kiselina sa diazodifenilmetanom u aprotičnim rastvaračima
(Serbian Chemical Society, Belgrade, 2009)
The rate constants for the reactions of diazodiphenylmethane (DDM) with 6-substituted nicotinic acids in aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents, together with ...
Non-isothermal crystallization of k2o center dot tio2 center dot 3geo(2) glass
(Springer, Dordrecht, 2009)
The crystallization of K2O center dot TiO2 center dot 3GeO(2) glass under non-isothermal condition was studied. In powdered glass with particle sizes less than 0.15 mm, surface crystallization was dominant and an activation ...
Corrosion behaviour of epoxy coatings on modified aluminium surfaces
(Bulletin of Electrochemistry, 2002)
The electrochemical and transport properties and thermal stability of epoxy coatings electrodeposited on aluminium and modified aluminium surfaces (anodized phosphatized and chromatized-phosphatized aluminium) have been ...
Synthesis of N-and N,N-dialkyl-S-alkylthiolcarbamates by the rearrangement of N-and N,N-dialkyl-O-thioncarbamates / Sinteza N- i N,N-dialkil-S-alkiltiol-karbamata premeštanjem N- i N,N-dialkil-O-alkiltionkarbamata
(Association of Chemical Engineers of Serbia, 2006)
A series of N- and N,N-dialkyl-S-alkylthiolcarbamates were synthesized by the rearrangement of N- and N,N-dialkyl-O-alkylthioncarbamates in the presence of diethyl sulfate. The synthesis of some compounds without catalyst ...
Mass transfer from the wall of a column to the fluid in a fluidized bed of inert spherical particles / Prenos mase zid-fluid u partikulativno fluidizovanim slojevima
(Association of Chemical Engineers of Serbia, 2004)
Mass transfer in fluidized beds is an important operation for separation processes. Two effects can be achieved by using fluidized beds in mass transfer processes increasing interface area and relative movement between the ...
The structure of bright zinc coatings / Struktura sjajnih prevlaka cinka
(Serbian Chemical Society, 2000)
The structures of bright zinc coatings obtained from acid sulfate solutions in the presenceof dextrin/salicylaldehyde mixture were examined. It was shown by the STM technique that the surfaces of bright zinc coatings are ...
