Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer Science and Business Media LLC, 2021)
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
The influence of the starch coating on the magnetic properties of nanosized cobalt ferrites obtained by different synthetic methods
(Elsevier, 2021)
To investigate the magnetic behavior of starch-coated cobalt ferrites, well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted ...

Properties of different types of dry electrodes for wearable smart monitoring devices
(Walter de Gruyter GmbH, 2020)
Wearable smart monitors (WSMs) applied for the estimation of electrophysiological signals are of utmost interest for a non-stressed life. WSM which records heart muscle activities could signalize timely a life-threatening ...
Microsized fayalite Fe2SiO4 as anode material: the structure, electrochemical properties and working mechanism
(Springer Science and Business Media LLC, 2021)
Fayalite Fe2SiO4 is synthesized by the solid-state reaction without ball milling. The obtained powder is further structurally and electrochemically examined. Field emission scanning electron microscopy (FESEM) showed that ...
The low-temperature sonochemical synthesis of up-converting β NaYF4:Yb,Er mesocrystals
(Elsevier BV, 2022)
In this paper, we report the mild sonochemical synthesis of hexagonal (β) NaYF4:Yb,Er mesocrystals at low temperature of 40 °C. The nucleation and transformation of crystal structures is investigated in the course of time, ...
Characterization of silicon carbide ceramics obtained from porous carbon structure achieved by plant carbonization
(Elsevier, 2020)
The aim of this research was to obtain a carbon solid residue by the carbonization process of biomass in an inert atmosphere which, through physical activation and chemical treatment (using TEOS - tetraethyl orthosilicate) ...
Removal of the As(V) and Cr(VI) from the Water Using Magnetite/3D-Printed Wollastonite Hybrid Adsorbent
(International Institute for the Science of Sintering (IISS), 2022)
In this study, the structure, morphology and composition of the synthesized magnetite/3D-printed wollastonite (3D_W/M) composite were characterized, and its adsorption performance with respect to As(V) and Cr(VI) were ...
Changes in long-term properties and natural cycles of the Danube river level and flow induced by damming
(Elsevier BV, 2021)
In this paper we assessed changes in scaling properties of the river Danube level and flow data, associated with building of Djerdap/Iron Gates hydrological power plants positioned on the border of Romania and Serbia. We ...
