Influence of welding current intensity on susceptibility to intergranular corrosion in welded joints of stainless steel / Uticaj jačine struje zavarivanja na sklonost prema interkristalnoj koroziji zavarenog spoja nerdajućeg čelika
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2017)
Susceptibility to intergranular corrosion in welded joints of austenitic stainless steel X5Cr-Ni18-10 was tested. The welding was performed with different intensity of welding current (110 A, 130 A and 150 A). The tests ...
Examination of phosphate ores bioleaching from Lisina deposit / Ispitivanje mogućnosti bioluženja fosfora iz fosfatne rude sa ležišta Lisina
(Belgrade, Serbia : Engineering Society for Corrosion, 2012)
Phosphorus solubilization from insoluble phosphate ores by acidophilic autotrophs and heterotrophs is a research of significant interest, because of potential use of these ores as fertilizers, which are economically and ...
Aromatic π-networks in Sm/LSm protein interfaces / Aromatična π-mreža u interfejsima Sm/LSm proteina
(Univerzitet u Nišu, 2014)
In this work, we have analyzed the influence of π-π interactions on stability and properties of Sm/LSm assemblies. The residues were found to be involved in π-π interactions much more frequently than Tyr or His. Similarly, ...
Elektrohemijsko određivanje antimona na elektrodama sa poli(vinil alkohol)/glina kompozitom / Electrochemical detection of antimony on electrodes based on poly(vinyl alcohol)/clay composites
(Beograd : Savez inženjera i tehničara Srbije, 2019)
Sintetisani su kompoziti gline i poli(vinil alkohola) (PVA) sa masenim odnosima PVA/glina 10% i 20%. Kompoziti su naneti na površinu disk elektrode od staklastog ugljenika pomoću Nafiona. Tako modifikovane elektrode su ...
Determination of ionization constants (PKA) of β-hydroxy-β-arylalkanoic acids using high-pressure liquid chromatography
(University of Kragujevac, Faculty of Science, 2018)
pKa values of five β-hydroxy-β-arylalkanoic acids and ibuprofen were determined using the RP-HPLC method. Stationary phase was octadecyl modified (C-18) silica gel, and mobile phase was a mixture of methanol and one of ...
Viability of newly developed process for catalytic conversion of bio-glicerin into various 'green chemical' and development opportunities for Serbia
(Institut za istraživanja i projektovanja u privredi, Beograd, 2016)
Crude bio-glycerin is a by-product in the production of biodiesel. An economically efficient valorization of crude bio-glycerin usually significantly defines the profitability of the biodiesel plant. A strong technological ...
