The synthesis, characterization, antioxidant and antimicrobial activity of some novel amides of the esters of substituted 1,4-dihydropyridines / Синтеза, карактеризација, антиоксидативна и антимикробна активност некиx нових амида естара 1,4-дихидропиридина
(Serbian Chemical Society, 2024)
The esters of substituted 1,4-dihydropyirdines (1,4-DHP) are formed in the reaction of an appropriate aldehyde and ethyl acetoacetate in the presence of concentrated water solution of ammonia. The esters form the amides ...
The influence of antioxidant and post-synthetic treatment on the properties of biodegradable poly(butylene succinate)s modified with poly(propylene oxide) / Uticaj antioksiodansa i načina izdvajanja polimera na svojstva biodegradabilnih poli(butilen sukcinata) modifikovanih poli(propilenoksidom)
(Serbian Chemical Society, Belgrade, 2007)
Novel poly(ester-ether)s based on poly(butylene succinate) (PBS) as the hard segments and 30 mass % of poly(propylene oxide) (PPO) as the soft segments were synthesized with varying amount of the antioxidant (N,N'-diphen ...
Determination of the absolute hardness of electrolytically produced copper coatings by application of the Chicot–Lesage composite hardness model / ОДРЕЂИВАЊЕ АПСОЛУТНЕ ТВРДОЋЕ ЕЛЕКТРОЛИТИЧКИ ДОБИЈЕНИХ ПРЕВЛАКА БАКРА ПРИМЕНОМ CHICOT–LESAGE КОМПОЗИТНОГ МОДЕЛА ТВРДОЋЕ
(Serbian Chemical Society, 2022)
In this study, a novel procedure, based on application of the Chicot––Lesage (C–L) composite hardness model, was proposed for the determination of an absolute hardness of electrolytically produced copper coatings. The Cu ...
Synthesis, structure and properties of thermoplastic poly(ester-siloxane) elastomers
(Serbian Chemical Society, 2006)
Two series of thermoplastic poly(ester-siloxane) elastomers (TPES), with hard segments based on poly(butylene terephthalate) (PBT) and soft segments based on poly(dimethylsiloxane) (PDMS), were synthesized by high-temperature, ...
Use of the SSF equations in the Kojima-Moon-Ochi thermodynamic consistency test of isothermal vapour-liquid equilibrium data
(Serbian Chemical Society, 2000)
The Kojima-Moon-Ochi (KMO) thermodynamic consistency test of vapour-liquid equilibrium (VLE) measurements for 32 isothermal data sets of binary systems of various complexity was applied using two fitting equations: the ...
Electrochemical properties of mixed WC and Pt-black powders / Elektrohemijska svojstva smeše prahova WC i Pt
(Serbian Chemical Society, Belgrade, 2008)
The electrochemical characteristics of a mixture of Pt-black and WC powders and its catalytic activity for methanol and formic acid oxidation were investigated in acid solution. XRD and AFM measurements revealed that the ...
Kinetics and mechanism of As2S2 oxidation / Кинетика и механизам процеса оскидације једињења Аs2S2
(Serbian Chemical Society, 2005)
The kinetics of realgar (As2S2) oxidation was studied under isothermal and non-isothermal conditions. The obtained values of the activation energy indicate that the process occurs in the kinetic domain with the realgar ...
1,3-Propanediammonium [μ4-1,2,4,5-benzenetetracarboxylato(4-) ]copper(II) dihydrate with a microporous structure
