FTIR study of carbon monoxide adsorption on ion-exchanged X, Y and mordenite type zeolites / FTIR studija adsorpcije ugljen-monoksida na izmenjenim zeolitima tipa X, Y i mordenita
(Srpsko hemijsko društvo, Beograd, 2003)
In this work Fourier transform infrared (FTIR) study has been applied to study the adsorption of carbon monoxide on transition metal (Mn2+, Co2 Ni2+) ion-exchanged zeolites type Y, X and mordenites. The adsorption of CO ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder, III: A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current / Uticaj oblika I strukture čestica na tečljivost elektrolitičkog bakarnog praha III - model površine reprezentativne čestice tečljivog bakarnog praha dobijenog elektohemijskim taloženjem reversnom strujom
(Srpsko hemijsko društvo, Beograd, 2004)
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow. It is shown that such structures can be easily obtained in the ...
The synthesis and pharmacological evaluation of (±)-2, 3- seco-fentanyl analogues / Sinteza i farmakološko ispitivanje (±)-2,3-seco-analoga fentanila
(Srpsko hemijsko društvo, Beograd, 2004)
An efficient, five-step synthetic approach to various acyclic 1,3-diamines has been developed and applied to the preparation of a novel class of open-chained fentanyl analogues. The acyclic derivatives 5.1–5.5 (all new ...
Comparison of the swelling kinetics of a partially neutralized poly(acrylic acid) hydrogel in distilled water and physiological solution / Poređenje kinetike bubrenja hidrogela delimično neutralisane poli(akrilne) kiseline u destilovanoj vodi i fiziološkom rastvoru
(Srpsko hemijsko društvo, Beograd, 2007)
The isothermal kinetics curves of the swelling of a poly(acrylic acid) hydrogel in distilled water and physiological solution at temperatures ranging from 20 to 40 ºC were determined. The possibility of applying both the ...
Influence of yeast and nutrients on the quality of apricot brandy
(Srpsko hemijsko društvo, Beograd, 2014)
Five yeast strains Saccharomyces cerevisiae and S. bayanus (SB, Top Floral, Top 15, Aroma White and Red Fruit) and two nutrients, diammonium phosphate and Nutriferm Arom, were examined for their influence on young apricot ...
The effect of the particle shape and structure on the flow ability of electrolytic copper powder II: The experimental verification of the model of the representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha II - eksperimentalna potvrda modela reprezentativne čestice praha
(Srpsko hemijsko društvo, Beograd, 2003)
An analysis of the effects of the shape, surface structure and size distribution of particles on the flow ability of the copper powder was performed. It is shown that the most important property of the particles of a powder, ...
The synthesis and preliminary pharmacological evaluation of racemic cis and trans 3-alkylfentanyl analogues / Sinteza i preliminarni farmakološki testovi recemskih cis i trans 3-alkilanaloga fentanila
(Srpsko hemijsko društvo, Beograd, 2004)
A general, five step method for the synthesis of 3-alkylfentanyl analogues (i.e., cis and trans 3-alkyl-4-anilidopiperidines 6.1–6.6) has been developed. The starting N-phenethyl- 4-piperidone 1 was first converted into ...
An optimized synthesis of a key pharmaceutical intermediate methyl 4-[(1-oxopropyl)phenylamino]piperidine-4-carboxylate / Optimizovana sinteza značajnog farmaceutskog intermedijera metil 4-[(1-oksopropil)fenilamino]piperidin-4-karboksilata
(Srpsko hemijsko društvo, Beograd, 2002)
An efficient synthesis of methyl 4-[(1-oxopropyl)phenylamino]piperidine-4-carboxylate (7) has been developed starting from 1-benzylpiperidin-4-one (1). The compound is a key intermediate in the synthesis of new generation, ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder. I. Modeling of a representative powder particle
(Srpsko hemijsko društvo, Beograd, 2003)
One of the most important properties of copper powder is its flowability which depends on the shape and the structure of the powder particles. A procedure for the determination of a representative powder particle permitting ...
