Maltose-mediated, long-term stabilization of freeze- and spray-dried forms of bovine and porcine hemoglobin
(Srpsko hemijsko društvo, Beograd, 2019)
Slaughterhouse blood represents a valuable source of hemoglobin, which can be used in the production of heme-iron based supplements for the prevention/treatment of iron-deficiency anemia. In order to obtain a stable ...
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 ...
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 ...
Lead and silver extraction from waste cake from hydrometallurgical zinc production
(Srpsko hemijsko društvo, Beograd, 2008)
This paper presents the experimental results of the extraction of lead and silver from a lead-silver waste cake obtained in the process of hydrometallurgical zinc production. While controlling the pH value, the lead-silver ...
Specific transformations of mineral forms of nitrogen in acid soils / Specifičnosti transformacije mineralnih oblika azota u kiselim zemljištima
(Srpsko hemijsko društvo, Beograd, 2009)
Investigations were performed on soils of different acidity, ranging in the pH interval 4.65-5.80 (in water). Changes of the mineral nitrogen forms in the examined soils were studied by applying short-term incubation ...
Content of heavy metals in Gentiana lutea L. roots and galenic forms / Sadržaj teških metala u korenu i galenskim proizvodima gencijane (Gentiana lutea L.)
(Srpsko hemijsko društvo, Beograd, 2007)
An experimental field for the cultivated production of Gentiana lutea L. was established five years ago at the Suvobor Mountain, Serbia. Soil analysis of this area revealed the occurrence of high pseudo-total (Ni - 1270 ...
Comparative study of the active sites in zeolites by different probe molecules / Uporedno ispitivanje aktivnih centara zeolita različitim probnim molekulima

This review summarizes some of the recently published results concerning the acid sites in the zeolites ZSM-5 and Y studied by temperature-programmed desorption (TPD) and adsorption calorimetry using different probe molecules ...
Some negative chemical properties of acid soils / Neka negativna svojstva kiselih zemljišta
(Srpsko hemijsko društvo, Beograd, 2005)
Some important chemical properties of various samples of two types of acid soil from Western Serbia (pseudogley and brown forest) are presented in this paper. Mobile Al was found in elevated and toxic quantities (10–30 ...
A study of the adsorption thermodynamics of n-hexane on ion-exchanged X zeolites / Termodinamika adsorpcije n-heksana na jonski izmenjenim X zeolitima
(Srpsko hemijsko društvo, Beograd, 2005)
In this work, the free energy changes and entropy changes of adsorption of n-hexane on zeolites of the MxNa87-2xX (M=Co,Ni,Zn,Cd) type were determined using their isosteric sorption heats. It was found that the exchange ...
The effects of some agrotechnical measures on the uptake of nickel by maize plants / Uticaj nekih agrotehničkih mera na usvajanje nikla biljkama kukuruza
(Srpsko hemijsko društvo, Beograd, 2009)
Nickel is a non-essential element in the nutrition of the majority of plant species and can be toxic to plants when its concentration in soils is high. Several soil properties have an effect on the uptake of this heavy ...
