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 ...
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 ...
Integer Codes Correcting High-Density Byte Asymmetric Errors
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
In optical networks without optical amplifiers, the number of received photons never exceeds the number of sent ones. Hence, upon transmission, only asymmetric (1 → 0) errors can occur. Motivated by this fact, in this ...
Multifunctional and hybrid systems based on calcium-phosphate and hydroxyapatite for preventive and regenerative medicine / Multifunkcionalni i hibridni sistemi na bazi kalcijum fosfata i hidroksiapatita za preventivnu i regenerativnu medicinu
(Belgrade : Union of Engineers and Technicians of Serbia, 2017)
Thanks to its special caracteristics, such as relativly easy chemical modification of structure and surface, calciumphosphates (CaP) especially hydroxyapatite (HAp) is found widely used in various fields of biomedicine. ...
Two step sintering of ZnTiO3 nanopowder
(Belgrade : International Institute for the Science of Sintering, 2017)
Metastable nanopowder ZnTiO3 was pressed into cylindrical compacts at 200 MPa. Compacts were treated by conventional heating with isothermal holding at 931°C for 10 minutes, 25 minutes and 40 minutes. ZnTiO3 compacts were ...
Simultaneous enhancement of natural sunlight- and artificial UV-driven photocatalytic activity of a mechanically activated ZnO/SnO2 composite
(Royal Society of Chemistry, 2017)
Mechanical milling of commercial ZnO and SnO2 was used to produce a ZnO/SnO2 composite with a high density of surface defects; in particular, zinc interstitials (Zni) and oxygen vacancies (VO). To determine the impact of ...
Discrete temperature values in the sintering process as a BaTiO3-ceramics properties parameter
(Belgrade : International Institute for the Science of Sintering, 2017)
In this paper, we develop the new physical-mathematical time scale approach-model applied to BaTiO3-ceramics. At the beginning, a time scale is defined to be an arbitrary closed subset of the real numbers R, with the ...
Želatin kao nosač za isporuku polifenolnih komponenata / Gelatin as a carrier system for delivery of polyphenols compounds
(Belgrade : Union of Engineers and Technicians of Serbia, 2017)
In the present study, the influence of different encapsulation techniques (lyophilization and spray drying) on gelatin, as a carrier system for delivery of polyphenols compounds, on wild thyme extracts and on encapsulated ...
Influence of starting powder milling on magnetic properties of Mn-Zn ferrite
(Novi Sad : Faculty of Technology, University of Novi Sad, 2017)
In this paper, the influence of additional sieving and milling of starting industrial Mn-Zn powders on magnetic properties was investigated. The starting powder was milled for 60 minutes, followed by sieving through 325 ...
