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 ...
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 ...

(Beograd : Srpsko hemijsko društvo, 2016)
Sa ubrzanim razvojem nanotehnologije, celuloza kao najrasprostranjeniji i najvažniji prirodni polimer na zemiji privlači sve veću pažnju u formi nanoceluloze. Zbog svoje biodegradabilnosti, biokompatibilnosti i velike ...
ToF-ERDA/RBS analysis of annealed TiO2 nanotubes grown onto FTO glass
(Novi Sad : Faculty of Technology, 2019)
Different semiconductors have been studied as photoanode material for solar cells. Among them, TiO2 has been shown to be the best material due to its chemical stability and good charge transport capability. It is usually ...
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 ...
Stability of the gold mercaptotriazole complex at pH=4
(Bor : Mining and Metallurgy Institute, 2018)
The objective of this work was to investigate the stability of the gold complex based on
mercaptotriazole in slightly acid media, at pH=4. The gold complex complex was studied by the visual monitoring and electrochemical ...
