Flexibility index and decreasing the costs in energy systems with high share of renewable energy
(Elsevier BV, 2021)
Recent European Green Deal includes decision to become carbon neutral and even carbon negative region in order to tackle the climate crisis. Main technical challenge and a key factor in techno-economic analysis of the ...
Graph theory applied to microelectronics intergranular relations
(Taylor & Francis Group, 2021)
The focus of this study is on the control of layers between grains by applying graph theory. We performed modification of BaTiO3 nanoparticles with Y2O3. The results of capacitance change on submicron level are the part ...
Spray drying of Gentiana asclepiadea L. root extract: Successful encapsulation into powders with preserved stability of bioactive compounds
(Elsevier BV, 2021)
Willow gentian as a source of bitter compounds is traditionally used for digestive disorders. Gentiana root extract was spray dried using five different carriers (maltodextrin, whey protein, pectin, starch, gelatine) at ...
Uticaj stabilizatora na fizičkohemijska svojstva nanočestica selena dobijenih hemijskom redukcijom
(Beograd : Savez inženjera i tehničara Srbije, 2021)
Nanočestice selena (SeNPs) su specifična forma ovog elementa koja je u poslednje vreme postala predmet brojnih istraživanja, pogotovo u oblasti biomedicine. Do sada je razvijeno više metoda sinteze SeNPs, među kojima se ...
A kinetic study of D-glucose oxidation by bromine in aqueous solutions
(Oxford : Elsevier Sci Ltd., 2006)
The kinetics of the oxidation Of D-glucose to D-gluconic acid by bromine in aqueous solution were studied using potentiometric techniques and theoretical considerations of complex bromine-bromide-pH equilibria. The pH has ...
Nature of structural changes in LSM-YSZ nanocomposite material during thermal treatments
(Elsevier Science Sa, Lausanne, 2004)
Nanocomposite powders in the system (La1-xSx)(a)MnO3-YSZ((1-y)) [LSM-YSZ], as an attractive cathode material for high operating solid oxide fuel cell (SOFC), were obtained through ultrasonic spray pyrolysis (1.7 MHz) method. ...
Mechanochemical synthesis of gamma-Bi2O3
(Amsterdam : Elsevier, 2004)
A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) ...
The influence of alumino-silicate matrix composition on surface hydrophobic properties
(Belgrade : ETRAN, 2019)
The purpose of this investigation is to investigate the hydrophobicity of geopolymers, new alumino-silicate materials and the influence of Si/Al ratio on their surface properties. Contact angle measurement (CAM) as reliable ...
Three-Axis’ Heat Loss Anemometer Comprising Thick-Film Segmented Thermistors
(IEEE, 2019)
NTC thick-film segmented thermistors were used as anemometer sensing devices. They were screen printed of thick-film thermistor paste based on modified NiMn2O4 fine powder, organic vehicle, and glass frit. Their electrical ...
Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni+WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)from a commercially available Watts bath containing additives for brightness and smoothing and insoluble WCparticles, ...
