Stabilnost frekvencije kvarcnih oscilatora
(Društvo za ETRAN, 2022)
Oscilatorna kola su neizbežni deo praktično svih elektronskih uređaja. Najčešće se koriste kola na bazi kvarcnih kristala. Prikazan je proces proizvodnje i princip rada kvarcnih oscilatora, kao i podele kristala i oscilatornih ...
Impact properties of Kolon/PVB fabrics reinforced with rice-husk silica particles
(Materials Letters, 2022)
This study presents the impact properties of the new form of hybrid thermoplastic composites. The Kolon fabrics were impregnated with the 10 wt% poly (vinyl butyral) (PVB)/ethanol solution with the addition of silica (SiO2) ...
Presentation of software for applying simplex methods / Prezentacija softvera za primenu simpleks metoda
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije SMEITS, Društvo za obnovljive izvore električne energije, 2022)
This paper presents original software, developed for the needs of mathematical modeling of complex processes using the simplex method. The software was developed in the Delphi programming language for the Windows environment. ...
Influence of Post-Synthesis Treatments on the Properties of Brushite/Monetite Powders
(Belgrade : Serbian Academy of Sciences and Arts, 2022)
Dicalcium phosphate (DP) materials, of which brushite and monetite were the most known, have
been intensively studied for several decades because of excellent resorptive and osteoconductive
properties that can satisfy ...
The use of manganese(II)-pyromellitate complex precursor for the synthesis of nanosized manganese oxides
(Belgrade : Institut za multidisciplinarna istraživanja, 2022)
The increasing interest for nanosized mixed metal oxides such as spinels and
spinel-based materials in last decades has been motivated by their wide applications
in photocatalysis, magnetism or solar cells [1]. So far, ...
Modification of cellulose-based waste materials for removal of methylene blue from wastewater
(Belgrade : Society of Physical Chemists of Serbia, 2022)
Different natural fibers and yarns (hemp, flax, and cotton), obtained as a waste from textile industry,
were used for the removal of methylene blue from aqueous solution. In attempt to increase the
adsorption efficiency, ...
Activity Coefficients of the System { yKCl + (1 - y)KH2PO4}(aq) at T = 298.15 K Determined by Cell Potential Measurements
(American Chemical Society, 2022)
Zero-current cell potential measurements were used to determine the solution activity coefficient in a ternary system {yKCl + (1 - y) KH2PO4}(aq) at temperature T = 298.15 K. The cell of the type K-ISE|KCl(mKCl), ...
Environmental Neurotoxin β-N-Methylamino-L-alanine (BMAA) as a Widely Occurring Putative Pathogenic Factor in Neurodegenerative Diseases
(MDPI, 2022)
In the present review we have discussed the occurrence of β-N-methylamino-L-alanine (BMAA) and its natural isomers, and the organisms and sample types in which the toxin(s) have been detected. Further, the review discusses ...
Disparate soil textures as a native medium for As(V) and Pb(II) separation from aqueous systems
(Desalination Publications, 2022)
This study investigated the use of different natural raw soil materials as low-cost adsorbents for
the removal to remove As(V) and Pb(II) from aqueous systems. It deals with the effect of different soil textures, sandy ...
