The slag based adsorbents for Cu2+ removal from aquatic solutions
(Belgrade : Materials Research Society of Serbia, 2017)
This study aims to understand the kinetic, thermodynamic and mechanism of Cu2+ adsorption onto unmodified electric arc furnace slag (EAFS) and alkali modified EAFS. The adsorption process was investigated via a batch reactor ...
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 ...
Fractal Reconstruction of Fiber-reinforced Epoxy Microstructure
(Institute of Electrical and Electronics Engineers Inc., 2021)
In the past century, the use of polymers and composites with a polymer matrix has expanded to such a level that today it is impossible to imagine life without these materials. Epoxy resin and epoxy-based composites are ...
Planning of the high share of renewable sources within the Republic of Serbia Energy System: from 21.7 zo 40% - Can we reach 100%?
(Zagreb : Faculty of Mechanical Engineering and Naval Architecture, 2021)
Planning of energy systems in Serbia has long tradition and has been regularly performed for more than 60 years. Higher shares of renewable sources have been included just recently. The costs of such insufficiently planned ...
Simply prepared Mg-V-O as potential cathode material for rechargeable aqueous magnesium ion batteries
(Belgrade : Institute of Technical Sciences of SASA, 2021)
Although today widely used in electronic devices and electric vehicles, lithium ion batteries encounter problem of future application, resulting from limited Li resources, relatively high costs and operational safety ...
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, ...
Analysis of Intrinsic Stochastic Fluctuations of the Time Response of Adsorption-Based Microfluidic Bio/Chemical Sensors: the Case of Bianalyte Mixtures
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Real-time in situ operation of bio/chemical sensors assumes detection of chemical substances or biological specimens in samples of complex composition. Since sensor selectivity cannot be ideal, adsorption of particles other ...
Multi-sensor acquisition system for noninvasive detection of heart failure
(Belgrade : ETRANBelgrade : Academic Mind, 2019)
To research the possibility of noninvasive detection of heart failure we developed an acquisition system with multiple sensors. The system synchronously measures cardiovascular pulsations, heart sounds and ECG using different ...
