Trans- and cis-resveratrol concentration in wines produced in Serbia / Koncentracija trans- i cis-rezveratrola u vinima proizvedenim u Srbiji
(Srpsko hemijsko društvo, Beograd, 2008)
Resveratrol, which occurs in two isomeric forms, trans and cis, is a phytoalexin with numerous pharmacological activities, such as anti-cancer, antiviral, neuroprotective and anti-aging. Red wine is the main source of the ...
Aqueous extraction of anions from coal and fly ash followed by ion-chromatographic determination
(Srpsko hemijsko društvo, Beograd, 2016)
Three different techniques were applied for the aqueous extraction of anions from coal and fly ash: rotary mixer-and ultrasonic-assisted extraction with different duration time, and microwave-assisted extraction at different ...
Comparison of sequential and single extraction in order to estimate the environmental impact of metals from fly ash
(Srpsko hemijsko društvo, Beograd, 2016)
The aim of this paper is to simulate leaching of metals from fly ash in different environmental conditions using ultrasound and microwave-assisted extraction techniques. Single-agent extraction and sequential extraction ...
The effect of polar solvents on the synthesis of poly(urethane-urea-siloxane)s / Uticaj polarnih rastvarača na sintezu poli(uretan-urea-siloksana)
(Srpsko hemijsko društvo, Beograd, 2012)
Segmented poly(urethane-urea-siloxanes) (PUUS) based on 4,4'- methylene diphenyl diisocyanate-ethylene diamine (MDI-ED) hard segments and hydroxypropyl-terminated poly(dimethylsiloxane) (PDMS, Mn = 1000 g mol-1) soft ...
Effect of transition metal cations on the commensurate freezing of n-hexane confined in micropores of ZSM-5
(Srpsko hemijsko društvo, Beograd, 2015)
Besides its importance concerning fundamental studies on gas adsorption in narrow pores, investigation of the commensurate freezing of a fluid within a zeolite is of practical importance in the application of zeolites in ...
Investigation of different extraction procedures for the determination of major and trace elements in coal by ICP-AES and ion chromatography
(Srpsko hemijsko društvo, Beograd, 2016)
This paper presents the extraction of major and trace elements from a coal sample, in deionized water, by using three different extraction techniques. Rotary mixing and ultrasonic extraction were examined for different ...
The use in grass production of clinoptilolite as an ammonia adsorbent and a nitrogen carrier
(Srpsko hemijsko društvo, Beograd, 2015)
Clinoptilolite-rich tuff (NZ) from the Zlatokop deposit (Vranjska Banja, Serbia) was studied as a nitrogen carrier for grass production. The mechanism of binding ammonium cations present in aqueous solutions by NZ was ...
Structural, thermal and surface characterization of thermoplastic polyurethanes based on poly(dimethylsiloxane)
(Srpsko hemijsko društvo, Beograd, 2014)
In this study, the synthesis, structure and physical properties of two series of thermoplastic polyurethanes based on hydroxypropyl-terminated poly(dimethylsiloxane) (HP-PDMS) or hydroxyethoxypropyl-terminated poly(dimet ...
High antioxidative potential and low toxic effects of selenosemicarbazone metal complexes / Visoki antioksidativni potencijal i mali toksični efekat selenosemikarbazonskih kompleksa
(Srpsko hemijsko društvo, Beograd, 2013)
Novel metal-based compounds with therapeutic potential have become the subject of intense investigations in inorganic chemistry and biomedical science. Recently, strong dose-dependent cytotoxic activities of selenosemicarbazone ...
Influence of bunch morphology on quality of wines produced from clones of grape variety Prokupac
(Srpsko hemijsko društvo, Beograd, 2016)
Wine quality depends mainly on the characteristics of the grape it is made of, and one of the attributes affecting wine composition is cluster and berry morphology. The aim of this study was to represent variability of the ...
