Uklanjanje estrona, 17β-estradiola i 17α-etinilestradiola iz vode na aktivnim ugljeničnim tkaninama
(Beograd : Visoka škola strukovnih studija Beogradska politehnika, 2017)
Prisustvo estrogenih hormona u vodenim resursima čak i u veoma niskim koncentracijama (reda
veličine ng/L) može dovesti do niza funkcionalnih poremećaja kod akvatičnih organizama, kao što
su poremećaj u radu endokrinog ...
Assessment of Safety Valve Springs Failure
(Materials Research Society of Serbia, Srbija, 2011)
The aim was to investigate the cause of failure of as-received ultra-high strength steel springs,
which were deposite-coated. The qualitative analysis of surrounding environment was performed.
Springs were visually and ...
Adsorption and photocatalytic degradation of methylene blue on carbon monolith with TiO2 coating
(Srpsko hemijsko društvo, 2013)
Silver micro-sized powder obtained by the chemical reduction
(Bor : Mining and Metallurgy Institute, 2018)
This paper presents the method for preparation the fine Ag powder with a particles size smaller than 2 μm. Reduction was performed from the nitrate solution directly by the vigorous stirring at the room temperature by the ...
Stability of gold complex based on mercaptotriazole with gold concentration lower than optimal
(Bor : University of Belgrade, Technical Faculty, 2017)
The aim of this work was to investigate the stability of the gold complex based on mercaptotriazole at optimum pH value of nine in the electrolyte with gold concentration of 1.5 g/dm3. Investigations were performed by ...
ZIGZAG METAL-ORGANIC POLYMER: (2,2’-DIPYRIDYLAMINE)(TEREPHTALATO)ZINC(II) HYDRATE / CIK-CAK METAL-ORGANSKI POLIMER: (2,2’-DIPIRIDILAMIN)(TEREFTALATO)CINK(II)-HIDRAT
(Beograd : Srpsko kristalografsko društvo, 2014)
Anions of terephthalic (1,4-benzenedicarboxylic) acid, tpht2–, act as a potential
polydentate and bridging ligands in metal-organic framework structures. COO groups are
usually coordinated either in mono-, bi- or polydentate ...
Nanocomposite Hydrogels Based on Poly(vinyl alcohol) and Chitosan with Silver Nanoparticles and Graphene Aimed for Wound Dressing Applications
(Belgrade : Serbian Academy of Sciences and Arts, 2018)
In this work, we prepared hydrogels based on PVA, CHI and Gr, and used them
as a porous matrix to synthesize silver nanoparticles by an in situ electrochemical
method [3,4]. The hydrogels were prepared from PVA/CHI/Gr ...
Аntioxidant activity of peptide fractions obtained by membrane ultrafiltration of egg white protein enzymatic hydrolysates
(Zvornik : Tehnološki fakultet, 2015)
The objective of this research was a production of egg white protein hydrolysates with improved antioxidant properties. For this purpose, a thermal and ultrasound pretreated egg white proteins were intensively hydrolysed ...
Peptides with improved antimicrobial activity screened by membrane ultrafiltration from egg white protein hydrolysates
(Bratislava, SK : Slovak Society of Chemical Engineering, 2015)
This contribution was aimed at the fractionation and identification of peptides with improved
antimicrobial activity from egg white protein hydrolysates, obtained by membrane ultrafiltration. For
this purpose, the thermal ...
CORROSION BEHAVIOUR OF AN Al-Zn-Mg-Cu ALLOY AFTER DIFFERENT HEAT TREATMENTS
(Technical faculty Mihajlo Pupin, Zrenjanin, University of Novi Sad, Srbija, 2012)
The variation of factors such as the amount of alloying elements in solid solution, thermal and
thermo-mechanical treatments changes the corrosion tendency in the Al-Zn-Mg-Cu alloy. The measurements of
electrical ...
