Degradability of n-alkanes during ex situ natural bioremediation of soil contaminated by heavy residual fuel oil (mazut) / Degradabilnost normalnih alkana za vreme ex situ prirodne bioremedijacije zemljišta zagađenog mazutom
(Srpsko hemijsko društvo, Beograd, 2013)
It is well known that during biodegradation of oil under natural geological conditions, or oil pollutants in the environment, degradation of hydrocarbons occurs according to a well-defined sequence. For example, the major ...
Randomly oriented twin domains in electrodeposited silver dendrites
(Srpsko hemijsko društvo, Beograd, 2015)
Silver dendrites were prepared by electrochemical deposition. The structures of the Ag dendrites, the type of twins and their distribution were investigated by scanning electron microscopy (SEM), Z-contrast high angle ...
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 ...
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 ...
Investigation of the bioremediation potential of aerobic zymogenous microorganisms in soil for crude oil biodegradation
(Srpsko hemijsko društvo, Beograd, 2011)
The bioremediation potential of the aerobic zymogenous microorganisms in soil (Danube alluvium, Pancevo, Serbia) for crude oil biodegradation was investigated. A mixture of paraffinic types of oils was used as the substrate. ...
A comparison of sample extraction procedures for the determination of inorganic anions in soil by ion chromatography / Uticaj pripreme uzorka zemljišta na određivanje neorganskih anjona metodom jonske hromatografije
(Srpsko hemijsko društvo, Beograd, 2011)
Three different extraction techniques were used for aqueous extraction of anions from soil of the type Ranker that was sampled from a serpentine site. The first technique involved the use of a rotary mixer (rotary mixer ...
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 ...
Influence of the content of hard segments on the properties of novel urethane-siloxane copolymers based on a poly(ε-caprolactone)-b-poly(dimethylsiloxane)-b-poly(ε-caprolactone) triblock copolymer / Uticaj sadržaja tvrdog segmenta na svojstva novih uretan-siloksanskih kopolimera na bazi poli(e-kaprolakton)-b-poli(dimetilsiloksan)-b-poli(e-kaprolaktona)
(Srpsko hemijsko društvo, Beograd, 2011)
A series of novel thermoplastic urethane-siloxane copolymers (TPUSs) based on a α,ω-dihydroxy-[poly(ε-caprolactone)-b-poly(dimethylsiloxane)-b- -poly(ε-caprolactone)] (α,ω-dihydroxy-PCL-PDMS-PCL) triblock copolymer, ...
Chemical composition of white currant seed extract / Hemijski sastav ekstrakta semenki bele ribizle
(Srpsko hemijsko društvo, Beograd, 2011)
From the seeds of white currant (Ribes rubrum, cv. White Champagne), a new sesquiterpenoid glycoside 1 was isolated, along with two known compounds: dihydrophaseic acid 3'-O-b-D-glucopyranoside (2), and 3-carboxymethyl-i ...
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 ...
