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 ...
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 ...
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 ...
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 ...
Synthesis and high in vitro cytotoxicity of some (S,S)-ethylenediamine-N,N '-di-2-propanoate dihydrochloride esters
(Srpsko hemijsko društvo, Beograd, 2014)
A novel (S,S)-R(2)eddip ester, O,O'-diisopentyl-(S,S)-ethylenediamine-N,N'-di-2-propanoate dihydrochloride (1) was synthesized and characterized by IR, H-1- and C-13-NMR spectroscopy, mass spectroscopy and elemental analysis. ...
Effect of the orientation of the initially formed grains on the final morphology of electrodeposited lead
(Srpsko hemijsko društvo, Beograd, 2014)
The processes of Pb electrodeposition under diffusion control were examined by scanning electron microscopy (SEM) of the formed crystals. The orientation of grains of hexagonal shape formed in the initial stage of ...
LC/DAD determination of biogenic amines in serum of patients with diabetes mellitus, chronic urticaria or Hashimoto's thyroiditis
(Srpsko hemijsko društvo, Beograd, 2016)
Biogenic amines are integral part of nearly every cell. In the present study, the method of acidic extraction of histamine (His), of polyamines putrescine (Put), spermidine (Spd) and catecholamines epinephrine (Epi) and ...
