Coexistence of several sillenite-like phases in pseudo-binary and pseudo-ternary systems based on Bi2O3
(Elsevier, Amsterdam, 2013)
A series of polycrystalline samples containing sillenite-like (doped gamma-Bi2O3) phases were prepared by high-temperature reactions from alpha-Bi2O3 powder and different oxides in six pseudo-binary Bi2O3-MxOy (M = Mn, Ti, ...
Synthesis of tetraalkylthiuram disulfides using different oxidants in recycling solvent mixture / Sinteza tetraalkiltiuram-disulfida primenom različitih oksidacionih sredstava u reciklovanoj smeši rastvarača
(Association of the Chemical Engineers of Serbia, 2012)
A new optimized laboratory synthesis of tetraalkylthiuram disulfides, starting from dialkyl amines and carbon disulfide in presence of three oxidants (hydrogen peroxide, potassium peroxodisulfate and sodium hypochlorite) ...
The antioxidant properties of dried extracts from spent espresso coffee / Antioksidativna svojstva sušenih ekstrakata iz otpadne espreso kafe
(Association of Chemical Engineers of Serbia, 2013)
The importance of coffee waste utilization is based on the fact that it contains a large amount of biologically valuable components. Preparation of espresso coffee produces substantial quantities of polyphenolic acids that ...
Isolation of Hemoglobin from Bovine Erythrocytes by Controlled Hemolysis in the Membrane Bioreactor
(Springer, New York, 2012)
In this work, we describe an optimized procedure based on gradual hemolysis for the isolation of hemoglobin derived from bovine slaughterhouse erythrocytes in a membrane bioreactor. The membrane bioreactor system that ...
A study of the photocatalytic degradation of the textile dye CI Basic Yellow 28 in water using a P160 TiO2-based catalyst / Proučavanje fotokatalitičke degradacije tekstilne boje CI Basic Yellow 28 u vodi koristeći P160 katalizator na bazi TiO2
(Serbian Chemical Society, Belgrade, 2012)
The photocatalytic degradation of the synthetic textile dye CI Basic Yellow 28 (BY28) in water, using a recently synthesized P160 TiO2-based catalyst, under Osram ultra-vitalux® lamp (300 W) light, was studied. The effects ...
The effects of solvents and structure on the electronic absorption spectra of the isomeric pyridine carboxylic acid N-oxides / Uticaj rastvarača i strukture na elektronske absorpcione spektre izomernih piridin-karboksilnih kiselina N-oksida
(Association of the Chemical Engineers of Serbia, 2013)
The ultraviolet absorption spectra of the carboxyl group of three isomeric pyridine carboxylic acids N-oxides (picolinic acid N-oxide, nicotinic acid N-oxide and isonicotinic acid N-oxide) were determined in fourteen ...
Antioxidative capacity of fermented red bean and its protein hydrolysate fractions / Antioksidativni kapacitet fermentisanog crvenog pasulja i njegovih proteinskih hidrolizata
(Društvo za ishranu Srbije, Beograd, 2012)
In this study we investigated the antioxidant activity of native and fermented red bean, or their polyphenol and peptide fractions. It was found that the antioxidant activity determined by DPPH, FRAP and TBA, significant ...
Densities and derived thermodynamic properties for the (n-heptane plus n-octane), (n-heptane plus ethanol) and (n-octane plus ethanol) systems at high pressures
(Academic Press Ltd- Elsevier Science Ltd, London, 2016)
This work reports densities for the pure n-heptane, n-octane and ethanol at temperatures from (288.15 to 413.15) K and at pressures up to 60 MPa. The same properties were determined for the binary mixtures n-heptane + ...
Structural Properties of the Multiwall Carbon Nanotubes/Poly(Methyl Methacrylate) Nanocomposites: Effect of the Multiwall Carbon Nanotubes Covalent Functionalization
(Wiley, Hoboken, 2017)
The structural characteristics of polymer nanocomposites with functionalized multiwall carbon nanotubes (MWCNTs) in poly(methyl methacrylate) matrix have been studied in relation to nanofiller loading and surface functionality. ...
In situ photoreduction of Ag+-ions by TiO2 nanoparticles deposited on cotton and cotton/PET fabrics
