Efekti adsorpcione obrade solventnih baznih ulja aktiviranih bentonitom / Effect of Adsorption Processing of Solvent Base Oils by Activated Bentonite
(Academy of Sciences and Arts of the Republic of Srpska, 2014)
Solvent base oils of group API I contain larger quantities of aromatic compounds and sulfur, as compared to base oils of higher quality groups. Processing of base oils by commercial clays is performed in order to reduce ...
Resonant frequency and phase noise of nanoelectromechanical oscillators based on two-dimensional crystal resonators
(Elsevier, 2014)
This study presents a theoretical analysis of one of the most promising nanoelectromechanical (NEMS) components - A NEMS oscillator. The analyzed oscillator contains a stretched circular plate, fabricated of two-dimensional ...
Potential environmental application of microbial polysaccharides
(Abstracts CD - 23rd Symposium on Environmental Chemistry, Kyoto, Japan, 2014)
Here we report toxicity inhibition effect of microbial exopolysaccharides on copper (II) in acute toxicity tests with Artemia salina and Daphnia magna.
Photocatalytic activity of peg-modified catalysts
(Society of Physical Chemists of Serbia, 2014)
This work is focused on the influence of polyethylene glycol (PEG) onstructural, textural and photocatalytic properties of titanium dioxide (TiO2)catalyst. Catalysts were synthesized by sol-gel method using PEG withdifferent ...
Preparation of Ni/diatomite hydrogenation catalyst precursors: Effect of counter ions on textural characteristics
(Society of Physical Chemists of Serbia, 2014)
Diatomite supported nickel catalyst precursors (Ni/D) were prepared by the precipitation-deposition (PD) method using different nickel salts such as nitrate, chloride, acetate and formate. The effect of counter ions (NO3-, ...
Preparation of CaO/γ-Al2O3 catalyst for biodiesel fuels. The catalytic activity in relation to thermal treatment
(Society of Physical Chemists of Serbia, 2014)
A heterogeneous base catalyst (CaO/γ-Al2O3) for biodiesel production from sunflower oil was prepared by the impregnation method. The catalyst was characterized by means of MIP and XRD methods. The catalytic activity of the ...
Adsorption–desorption based random number generator
(Belgrade : Military Technical Institute, 2014)
Data tracking and hacking is especially dangerous in modern defence forces where classified data transmission must envolve cryptographic methods for secure and reliable data coding. The more unpredictable the cipher is, ...
Structure and magnetic properties of nanocrystalline NiFe2O 4 prepared via precipitation route
(Polish Academy of Sciences, 2014)
Nanocrystalline Ni-ferrite was synthesized by modified precipitation method in which soluble starch is used as dispersing agent and Na2CO 3 as a precipitating agent. NiSO4-6H2O and Fe(NO3)3-9H2O were used as precursors for ...
Mathematical modeling of ethanol effects on the HPA axis dynamics
(Elsevier Science Inc, New York, 2014)
Synthesis of gold nanoparticles using aldehyde functionalized levan as reducing agent
(Belgrade : Society of Physical Chemists of Serbia, 2014)
In this work, gold nanoparticles (AuNPs) were synthesized in aqueous solution by aldehyde functionalized microbial polysaccharide levan as a reducing agent. Resulting nanoparticles were characterized by UV-Vis spectroscopy ...
