The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Srpsko hemijsko društvo, Beograd, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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. 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 ...
