Effects of chronic oral D-galactose treatment on general health status in male Wistar rats
(Belgrade : Vinča Institute of Nuclear Sciences, 2021)
D-galactose (d-gal) is an important physiological nutrient. According to the
widely accepted aging metabolic theory d-gal at high levels can be converted
into aldose and hydroperoxide, resulting in the overproduction of ...
Biblioteke naučnoistraživačkih instituta i ustanova: zakonodavni okvir i praksa
(Čitalište, 2016)
U Srbiji postoji više od 70 akreditovanih naučnih instituta, ustanova i centara izuzetnih vrednosti, sa bibliotekama čiji knjižni fondovi često premašuju fondove fakultetskih biblioteka, sa bibliotekarima i knjižničarima ...
The influence of mechanical activation on sintering process of BaCO3-SrCO3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2012)
In this article the influence of mechanical activation on sintering process of bariumstrontium-titanate ceramics has been investigated. Both non-activated and mixtures treated in a planetary ball mill for 5, 10, 20, 40, ...
Synthesis and characterization of ZnO nano/micro crystals with enhanced sunlight-induced photo-catalytic activity
(Belgrade : Serbian Ceramic Society, 2021)
It is known that the functional properties of zinc oxide (ZnO) materials depend on their physico-chemical properties, such as optical properties and specific surface area. They are defined with structural characteristics, ...
Structural analysis of Zn2TiO4 doped with MgO
(Springer, 2009)
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
Injectable polydimethylsiloxane-hydroxyapatite composite cement
(Bio-Medical Materials and Engineering, 2003)
An injectable polydimethylsiloxane/hydroxyapatite (PDMS/HAp) composite cement was synthesised using linear PDMS and HAp (particles of about 100 nm in size) of different mass fractions. The effect of HAp mass fraction (5-60 ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Elsevier, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm-3 HClO4, saturated with H2 containing 100 ppm CO, was examined with rotating disc ...
The ceramics materials density defined by artificial neural networks
(Belgrade : Serbian Ceramic Society, 2021)
Predicting the ceramic materials properties and designing the desired microstructures characteristics are very important objectives in ceramic samples consolidating process. The goal of our research is to calculate the ...
Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer Science and Business Media LLC, 2021)
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
The influence of the starch coating on the magnetic properties of nanosized cobalt ferrites obtained by different synthetic methods
(Elsevier, 2021)
To investigate the magnetic behavior of starch-coated cobalt ferrites, well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted ...
