Hydrogenation of soybean oil over Ag-Ni/diatomite catalysts. Effect of silver content on the cis/trans isomerization selectivity
(Materials Science Forum, 2006)
Silver promoted nickel catalysts supported on diatomite were prepared by precipitation method. Characterization of the catalysts prepared with different silver contents (0.1-4.0 wt%) included AAS, XRD, Hg porosimetry, BET ...
Mathematical modelling and simulation of drawing thin glass sheet from a rectangular preform
(Society of Glass Technology, 1998)
A mathematical model of thin glass sheet drawing has been developed. This model includes momentum, heat and mass balance equations. The density, viscosity and specific heat of the glass were calculated as functions of ...
Ibuprofen and diclofenac sodium adsorption onto functionalized minerals: Equilibrium, kinetic and thermodynamic studies
(Elsevier, 2022)
Cationic surfactant - octadecyldimethylbenzyl ammonium chloride (ODMBA) was used for modification of the three natural raw materials - bentonite, kaolin and zeolite. Adsorption of ODMBA by minerals occurred via ion exchange ...
Influence of cation−π interactions to the structural stability of phycocyanin proteins: A computational study
(Elsevier, 2022)
The influences of cation−π interactions in phycocyanin proteins and their environmental preferences were analyzed. The number of interactions formed by arginine showed to be higher than those formed by the lysine in the ...
Improving of hydrogen desorption kinetics of MgH2 by NaNH2 addition: Interplay between microstructure and chemical reaction
(Elsevier, 2022)
MgH2 based composites combined with NaNH2 were synthesized by mechanical milling for
three different milling times ranging from 15 to 60 minutes. Microstructure and particle
size of the samples were analyzed by SEM ...
Formation of dish-like holes and a channel structure in electrodeposition of copper under hydrogen co-deposition
(Elsevier, 2007)
Copper electrodeposition from acid sulfate solutions at an overpotential of 1000 mV, which is about 250 mV outside the plateau of the limiting diffusion current density, was examined by the determination of the average ...

Ова монографска библиографска публикација је научно дело које мултидисциплинарно повезује области техничких наука, херитологије, методологије, историје науке и филозофије технологија. Обухвата период од пола века значајног ...
Degradation of three typical hydroxamic acids collectors via UVA-B activated H2O2 and persulfate: Kinetics, transformation pathway, DFT calculation and toxicity evaluation
(Elsevier, 2023)
This work systematically studied the kinetics and mechanism of degradation of salicylhydroxamic acid (SHA), benzhydroxamic acid (BHA) and N-hydroxyphthalimide (NOP) by UVA-B/H2O2 and UVA-B/peroxodisulfate (PDS). UVA-B ...
Izolovanje i biohemijska karakterizacija mikroorganizama izolovanih iz aktivnog mulja postrojenja za preradu otpadnih voda "HIP Petrohemija" Pančevo
(Beograd: Udruženje mikrobioologa Srbije, 2015)
Pojedini mikroorganizmi zagađenih lokaliteta poseduju biohemijske mehanizme koji im omogućuju da zagađujuće supstance koriste kao izvor ugljenika i/ili elektrona. Bioremedijacija se može definisati kao proces u kome se ...
Antioxidative properties of infant formulas against hydroxyl radical production in the Fenton reaction
(University of Belgrade - Faculty of Chemistry, 2012)
Electron paramagnetic resonance (EPR) spin-trapping spectroscopy was used to compare the antioxidative capacities of commercial infant formulas against hydroxyl radical production in the Fenton reaction.
