Preparation and characterization of oxidized wheat starch with hydrogen peroxide as an environmentally friendly oxidant
(7th Conference of the Young Chemists of Serbia, 2019)
The starch oxidation involves oxidation of primary or secondary hydroxyl to carbonyl
or carboxyl groups, whereas the number of these groups indicates the level of oxidation.
Oxidized starch is used as surface sizing agent ...
Određivanje veštačkog zaslađivača neotama u rečnim sedimentima / Determination of artificial sweetener neotame in river sediments
(Beograd : Srpsko hemijsko društvo, 2019)
Veštački zaslađivači predstavljaju emergentne zagađujuće materije u životnoj sredini. Decenijama se koriste kao aditivi u ishrani i farmaceutskim proizvodima zbog čega su široko rasprostranjeni u prirodnim vodama usled ...
Adsorpcija estrogenih hormona iz vodenih rastvora na različitim ugljeničnim materijalima
(Beogradska politehnika, 2019)
U ovom radu vršena je adsorpcija estrogenih hormona (estrona, 17β-estradiola i
17α-etinilestradiola) na različitim ugljeničnim materijalima, u cilju ispitivanja primenljivosti ovih
materijala za uklanjanje estrogenih ...
Adsorptive, catalytic and antimicrobial applications of Serbian natural clinoptilolite
(Lublin University of Technology, Nadbystrzycka 40 20-618 Lublin, 2018)
Clinoptilolite is the most abundant natural zeolite in Serbia, and the Zlatokop deposit (near Vranjska Banja) is the largest deposit. The zeolitic tuff (CT) from Zlatokop contains >70 wt. % clinoptilolite with quartz and ...
Methods for determination of residual stress in rail
(Faculty of Mechanical Engineering, Niš, 2018)
The residual stresses in rails are generated during the manufacturing process and have uneven distribution in rail cross section. The residual stress is a part of basic tensile stress in rail foot. For used rail, the ...
RAMAN SPECROSCOPY STUDY OF ANODIC FILM ON Ag43Cu37Zn20 ALLOY
(Bor : Mining and Metallurgy Institute, 2015)
The aim of the present work is characterization of electrochemically treated Ag43-Cu37-Zn20 alloy in near neutral chloride solutions by the X-ray diffraction and Raman spectroscopy. At potential of +0.25 V, a complex ...
The effect of anions on the removal of dyes from textile industry wastewater / Uticaj anjona na uklanjanje boja iz otpadnih voda tekstilne industrije
(Serbian Chemical Society, Belgrade, 2019)
Textile industry wastewater represents a serious environmental problem because it contains different dyes and toxic substances used during the production and dyeing of textile. Thus, it is necessary to investigate the ...
Ag+-DOPED HYDROXYAPATITE: CELL PARAMETERS, MORPHOLOGY, THERMAL AND SPECTRAL PROPERTIES / HIDROKSIAPATIT DOPIRAN Ag+ -JONIMA: PARAMETRI JEDINIČNE ĆELIJE, MORFOLOGIJA, TERMALNA I SPEKTRALNA SVOJSTVA
(Beograd : Srpsko kristalografsko društvo, 2014)
Synthetic hydroxyapatite (HAp) [Ca10(PO4)6(OH)2] is very similar to the inorganic part
of bones and the dentine of teeth. Consequently, it has well known biocompatibility and
bioactivity, and it is nontoxic in any quantity ...
