Composition of red mud and/or metakaolin-based modified geopolymers
(Belgrade : Materials Research Society of Serbia, 2017)
There is potential use of red mud for synthesis of inorganic polymeric materials through a geopolymerization process as an alternative in the sectors of construction and building materials. By introducing of inorganic and ...
The Influence of Nanomaterial Calcium Phosphate/poly-(dl-lactide-co-glycolide) on Proliferation and Adherence of HeLa Cells
(Paris : Atlantis Press, 2017)
Nanomaterials are nowadays widely used in various fields of biomedicine. Before the application of biomaterials they have to be tested and fulfill some criteria. The first tests that should be performed after synthesis of ...
Effect of the vinyl modification of multi-walled carbon nanotubes on the performances of waste poly(ethylene terephthalate)-based nanocomposites
(SAGE, 2017)
Production of high-performance nanocomposite materials obtained from unsaturated polyester resin, based on products of the waste poly(ethylene terephthalate) recycling, and modified multi-walled carbon nanotubes is presented. ...
Fractal nature Heywang model correction and Brownian motions
(Belgrade : Serbian Ceramic Society, 2017)
Ceramics grains contacts are essential for understanding complex dielectric properties of electronic ceramics materials. Since the actual contact surface is an irregular object, the theory of fractal sets is applied. Also, ...
Synthesis of ZnO:Ag core-shell nanoparticles with enhanced photocatalytic properties by single - and two-steps USP
(Belgrade : Serbian Ceramic Society, 2017)
Synthesis of ZnO:Ag core-shell nanoparticles were performed by ultrasonic spray pyrolysis (USP) from the corresponding nitrate solutions. Varying relative concentrations of Ag and ZnO precursors and two different equipment ...
Photo-assisted electrochemical oxidation of the urea onto TiO2-nanotubes modified by hematite
(Elsevier, 2017)
The electrochemical oxidation of the urea in near neutral pH is investigated on platinum electrode. It is shown that oxidation reaction is practically inhibited up to the potentials of ∼0.9 V. The same reaction is investigated ...
Characterisation of Mn0.63Zn0.37Fe2O4 powders after intensive milling and subsequent thermal treatment
(Science of Sintering, 2017)
Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. The goal was to observe intensive milling influences on oxidation and reduction processes ...
Structural, electrical and magnetic properties of mechanically activated manganese and zinc ferrite
(Belgrade : Institute for Multidisciplinary Research of the University of Belgrade, 2017)
Starting hematite (Fe2O3), zinc oxide (ZnO) and manganese carbonate (MnCO3) powders were homogenized in a planetary ball mill in stainless steel bowls with stainless steel balls for 15 min, calcined in air at 1000 C for ...
Open Access Journals in Serbia: Policies and Practices
(Belgrade : National Library of Serbia, 2017)
This study is the result of the project Revisiting Open Access Journal Policies and Practices in Serbia, funded through the EIFL Open Access Programme. The project was implemented by the Serbian Library Consortium for ...
Functional electrical stimulation cycling strategies tested during preparation for the First Cybathlon Competition – a practical report from team ENS de Lyon
(Pavia : PAGEPress, 2017)
Whether it is from the patient’s or the physical therapist’s point of view, FES cycling can be considered either as a recreational activity, or an engaging rehabilitation tool. In both cases, it keeps patients with lower-limb ...
