Modified glycine nitrate procedure synthesis and properties of nanostructured Ca1-xGdxMnO3 (x=0.05; 0.1; 0.15; 0.2)
(Belgrade : Serbian Ceramic Society, 2021)
Nanocrystalline manganites Ca1-xGdxMnO3(x=0.05, 0.1, 0.15, 0.2) were synthesized by a modified glycine-nitrate procedure. The subsequent studies were focused on the structural, microstructural and magnetic changes of the ...
Effect of processing parameters on NaGdYF4:Yb,Er UCNPs structural, morphological and optical properties
(Belgrade : Institute of Technical Sciences of SASA, 2021)
Synthesis of monosized and spherical Up-Converting NanoParticles (UCNPs) with biocompatible surface are of a great interest because of their potential application in biomedicine as biomarkers or drug delivery systems. Among ...
On the Role of Poly-Glutamic Acid in the Early Stages of Iron(III) (Oxy)(hydr)oxide Formation
(Basel : MDPI AG, 2021)
Nucleation of minerals in the presence of additives is critical for achieving control over the formation of solids in biomineralization processes or during syntheses of advanced hybrid materials. Herein, we investigated ...
Dielectric characteristics of polymer nanocomposites based on PVDF and mechanically activated ZnO powder
(Belgrade : Serbian Ceramic Society, 2021)
ZnO powder was mechanically activated for 10 and 30 minutes in a high energy planetary ball mill, and mixed with 2 wt% PVDF solution to obtain nanocomposite films (50 μm) by casting. ZnO powder activated for 10 and 30 ...
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 ...
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, ...
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 ...
The influence of self-doping on electrochemical synthesis and behaviour of polyaniline / Uticaj samodopovanja na elektrohemijsku sintezu i svojstva polianilina
(Beograd : Udruženje inženjera Srbije za koroziju i zaštitu materijala UISKOZAM, 2021)
Electrochemical synthesis was used to polymerize aniline and copolymerize aniline and m-aminobenzoic from aqueous acidic electrolyte containing aniline and aniline with different amount of m-aminobenzoic acid. These materials ...
Aqueous electrolyte polypyrrole | zinc cell with supercapattery performance / Polipirol | cink ćelija sa vodenim rastvorom elektrolita i svojstvima superkapabaterije
(Beograd : Udruženje inženjera Srbije za koroziju i zaštitu materijala UISKOZAM, 2021)
Electrochemical oxidative polymerization at constant current density was used to produce polypyrrole (PPY) at graphite electrode from aqueous acidic electrolyte containing 0,1 mol dm-3 pyrrole and 1,0 mol dm-3 HCl. PPY ...
Modelling of argon/dust pulsed plasma
(European Physical Society, 2021)
A spatially-averaged model for an argon/dust pulsed plasma is developed in this study [1]. We analyze how the plasma properties depend on the shape of the electron energy probability function (EEPF), the pulsing frequency ...
