Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
Temperature dependence of the Kovats retention indices for alkyl 1, 3-diketones on a DB-5 capillary column / Temperaturna zavisnost kovačevih retencionih indeksa 1,3-diketonan a DB-5 kapilarnoj koloni
(Serbian Chemical Society, Belgrade, 2004)
A series of alkyl 1,3-diketones were used to study the temperature dependence of the Kovats retention indices in the temperature range 130–190 ºC (403–463 K). The temperature dependence is described by the empirical equation ...
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, ...
Alkylation of N-substituted-2-phenylacetamides / Alkilovanje n-supstituisanih 2-fenilacetamida
(Serbian Chemical Society, Belgrade, 2004)
Various N-substituted phenylacetamides were alkylated using different alkylating agents under neutral and basic conditions. Reactions were performed at different reaction temperatures and in various solvents. Also, a number ...
Synthesis and characterization of biodegradable aliphatic copolyesters with hydrophilic soft segments / Sinteza i karaterizacija biodegradabalnih alifatičnih kopoliestara modifikovanih mekim hidrofilnim segmentima
(Serbian Chemical Society, Belgrade, 2004)
segmented poly(ester-ether)s based on poly(butylene succinate) and two different types of polyethers were investigated. The poly(ester-ether)s were synthesized by transesterification reaction of dimethyl succinate ...

(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The aim of this work is to gain a better fundamental understanding of the nature Of Surface oxide sites present on activated carbon cloth (ACC) surface, and their role in the adsorption process. BET surface area of ACC was ...
The influence of the hydroxylic solvents on the reaction rates of diazodiphenylmethane with cycloalkylcarboxylic and cycloalkenylcarboxylic acids
(Natl Inst Science Communication, New Delhi, 2004)
The rate constants for the reaction of diazodiphenylmethane with cyclohexylcarboxylic, cyclopentylcarboxylic, cyclohex-3-enylcarboxylic and cyclopent-3-enylcarboxylic acids have been determined in ten alcohols at 30degreesC ...
Applicability of cubic equation of state mixing rules on correlation of excess molar volume of non-electrolyte binary mixtures
(Taylor & Francis Ltd, Abingdon, 2004)
The excess molar volume V data of the binary liquid systems were correlated by the Peng-Robinson-Stryjek-Vera equation of state coupled with two different types of mixing rules: composition dependent van der Waals mixing ...
