The influence of short thermal treatment on structure, morphology and optical properties of Er and Pr doped ceria pigments: Comparative study
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2019)
Potential non-toxic pink and red ceramic pigments based on CeO2 were successfully synthesized by self-propagating room temperature method and thermally treated at 600, 900 and 1200 degrees C for 15 min. The structure, ...
Adsorption performances of branched aminated waste polyacrylonitrile fibers: experimental versus modelling study
(Desalination Publ, Hopkinton, 2019)
Synthesis of branched aminated waste polyacrylonitrile (PAN) fibers, realized in a three addition/amidation successive steps, was performed in order to obtain AS3-PAN adsorbent. Influence of various operating parameters ...
Isopiestic Determination of the Osmotic and Activity Coefficients of the {yNaH(2)PO(4)+(1-y)KH2PO4}(aq) System at T=298.15K
(Springer/Plenum Publishers, New York, 2019)
Isopiestic measurements have been made for aqueous mixtures of NaH2PO4 and KH2PO4 at T=(298.15 +/- 0.01) K, at NaH2PO4 ionic strength fractions y=(0, 0.19108, 0.38306, 0.58192, and 1), assuming that both electrolytes ...
Biodegradation of cotton fabric impregnated with TiO2 nanoparticles
(Srpsko hemijsko društvo, Beograd, 2019)
Commercial P25 TiO2 nanoparticles are widely exploited as an efficient photocatalyst. In the textile domain, these nanoparticles are used for the production of self-cleaning, highly UV protective textiles, with an antimicrobial ...
Image analysis as a useful tool for fast detection of dimensional and structural changes of poly(ethylene terephthalate) containers
(Savez hemijskih inženjera, Beograd, 2018)
The aim of this paper is to present image analysis as a useful technique for fast, reliable and non-destructive detection of dimensional and structural changes in polymers. The possibility of applying image analysis was ...
Improving the synthesis process of tribological materials based on tin sulphides by adding graphite as additive
(Srpsko hemijsko društvo, Beograd, 2019)
The aim of this research was to study the effect of graphite addition in the process of synthesis of tribological materials based on tin sulphides. The tin sulphides powders were synthesized from selected precursors by ...
Treatment of the acidic effluent from a copper smelter by flotation tailings
(Savez hemijskih inženjera, Beograd, 2019)
Since commissioning in 1961, the copper mine Majdanpek, a part of the Mining and Smelting Complex Bor (RTB Bor), produced approximately 378 million tons of flotation tailings. Semiquantitative mineralogical analysis of the ...
Effects of caraway and juniper essential oils on aflatoxigenic fungi growth and aflatoxins secretion in polenta
(Wiley, Hoboken, 2019)
Inhibitory activity of caraway and juniper essential oils was tested against two aflatoxigenic strains (Aspergillus flavus-four isolates and Aspergillus parasiticus-one isolate) using the method of agar plates. A. flavus ...
Enzyme production by solid-state fermentation on soybean meal: A comparative study of conventional and ultrasound-assisted extraction methods
(Wiley, Hoboken, 2019)
Protease, cellulase, and alpha-amylase producing Bacillus subtilis strain was cultivated by solid-state fermentation technique using soybean meal as a substrate. The aim of the present study was to establish a highly ...
New spirohydantoins derived from beta-tetralone: design, synthesis and evaluation of their pharmacokinetically relevant propertie
